Sport: Soccer

Position: Goalkeeper

Athletes' bodies

Elite female soccer goalkeepers typically have an above-average stature and reach-oriented build, supporting maximal goal coverage for catching, punching, and shot-stopping. Compared with outfield positions, GK morphology shifts toward taller heights and somewhat higher body mass, with body-proportion traits (arm span/ape index, relatively longer lower-limb leverage) that favor dive distance and landing control.

Measurements

Factor	Prior	Posterior	Success-impact	Reasoning behind prior	Prior estimate sources
Height	169.6 ± 4.5 cm	169.6 ± 4.5 cm	high	Goalkeeper role benefits from height and reach; for elite female GK archetype, this target is anchored to the reported positional goalkeeper mean/SD (169.638 ± 4.482 cm) in a first-division women’s league study, assuming Sporty’s 'elite' cohort aligns directionally with top-level national/professional players.	[1]
Weight	60.8 ± 3.7 kg	60.8 ± 3.7 kg	high	GK requires strength for high-force catching/punching and safe landing/diving mass tolerance. The mean/SD is taken from the same positional goalkeeper value (60.81 ± 3.68 kg) to remain consistent with the height anchor.	[1]
Arm span	173 ± 5.3 cm	173 ± 5.3 cm	medium	Because direct GK arm-span tables weren’t available in the positional anthropometry source, arm span is set using a GK-friendly ape-index pattern (slightly >1.0) and modest SD to reflect reach variability while avoiding extreme outliers.	[2] [3]
Leg inseam	85.5 ± 3.8 cm	85.5 ± 3.8 cm	medium	For a ~170 cm female GK, inseam is set to reflect typical adult proportions and to support dive/landing leverage and lower-body reach. Value is a proportion-based estimate consistent with the height anchor.	[4]
Leg-torso ratio	1.39 ± 0.06 ratio	1.39 ± 0.06 ratio	medium	Goalkeeper diving/landing benefits from sufficient lower-limb leverage and an efficient trunk for balance. Therefore leg:torso is set moderately high but not extreme.	[5]
Shoulder-hip ratio	1.1 ± 0.06 ratio	1.1 ± 0.06 ratio	medium	A slightly higher shoulder:hip ratio supports upper-body stabilization and effective arm-driven reaching while still allowing leg-dominant dive mechanics.	[6]
Shoulder width	41 ± 2.7 cm	41 ± 2.7 cm	medium	Broader shoulders can support stable upper-body mechanics for catching/punching, but height/reach dominates the GK morphology story. Shoulder width is therefore set as moderately above average-but-plausible, with moderate SD.	[7]
Torso length	58.5 ± 3.1 cm	58.5 ± 3.1 cm	medium	A moderately long torso helps balance and trunk control during eccentric deceleration and dive initiation, without overly compromising leg drive.	[8]
Ankle circumference	20.6 ± 0.5 cm	20.6 ± 0.5 cm	low	This estimate is taken directly from the GK ankle perimeter reported in the positional table. It’s kept low importance because Sporty typically uses it more for injury/brace sizing realism than for core GK performance differentiation.	[1]
Ape index	1.03 ± 0.05 ratio	1.03 ± 0.05 ratio	low	Set slightly above 1.0 to reflect reach advantage for GK shot-stopping without making the model overly dependent on extreme long-limb proportions.	[2] [3]
Foot length	25.4 ± 1 cm	25.4 ± 1 cm	low	Foot length is set to match elite female stature proportions and to keep the measurement-model coherent. Performance importance is low relative to reach/height.	[8]
Hand length	18.7 ± 0.8 cm	18.7 ± 0.8 cm	low	Hand length may matter for effective catching surface, but Sporty’s GK archetype is modeled primarily via height/reach. Therefore hand length is set from adult anthropometric priors consistent with elite female stature.	[8]
Pelvic bone width	27.2 ± 2 cm	27.2 ± 2 cm	low	Pelvic width is not a primary GK selector trait, but a stable pelvis supports trunk stiffness and safe bracing during dives/contacts. Value is set slightly robust for an elite GK profile while keeping low importance in Sporty scoring.	[8]
Wrist circumference	14.5 ± 0.4 cm	14.5 ± 0.4 cm	low	Directly anchored to the GK wrist perimeter from the same positional anthropometry dataset; kept low importance for GK optimization since catch mechanics are driven more by reach/strength than by wrist circumference alone.	[1]

Traits

Factor	Value	Impact	Reasoning	Sources
Muscle fiber profile	balanced	high	GK actions are highly explosive (dives/jumps/reactions) but must be repeated across the match with effective submaximal positioning and recovery steps. This aligns best with a balanced fast/slow advantage rather than purely fast- or purely slow-twitch dominance.	[9] [10]
Metabolic tendency	mesomorphic tendency	medium	GK archetype is modeled as mesomorphic because it tends toward strength-capable, athletic builds (higher stature/mass than many outfield roles) while still requiring conditioning for repeated explosive actions.	[11] [12]
Joint laxity	medium	medium	Goalkeepers must be stable under landing impact and contact while still having enough range for dynamic reaching, stretching saves, and dive transitions—so medium laxity is the most defensible option.	[13]
Foot arch	neutral arch	low	Neutral arch is used as a pragmatic default because GK performance depends on traction and force transfer for dives/plant steps, but there’s not enough solid evidence to encode a universal arch-type optimum for elite female goalkeepers specifically.	[14]
Temperature tolerance	balanced	low	GK experiences the same general intermittent match structure and environmental exposures as other outfield roles; therefore no strong GK-only heat/cold specialization is assumed.	[15]
Dominant side	no meaningful side advantage	low	Some tactical matchups exist, but Sporty’s 'optimal profile' does not assume a universal dominant-side advantage for elite female goalkeepers, so it is set to neutral.	[16]

Goals

Factor	Alignment	Reasoning	Sources
Build confidence	medium	A goalkeeper can build confidence quickly when they learn positioning, handling, and communication—success is clearly visible (saves, claims, clean sheets). But the role also includes high-visibility mistakes (goals), so confidence can fluctuate depending on coaching, team support, and how you mentally process errors. ([link.springer.com](https://link.springer.com/article/10.1007/s40279-018-0977-2?utm_source=openai))	[17] [18]
Build endurance	low	“Endurance” in the aerobic sense usually comes from sustained running over time. Goalkeepers spend a lot of time in lower-movement readiness states, with bursts rather than continuous aerobic work. You may improve some cardio as a side effect of team practices, but the position is not the most reliable match-to-goal fit for building aerobic stamina. ([cris.brighton.ac.uk](https://cris.brighton.ac.uk/ws/portalfiles/portal/37748827/Accepted_Proof_The_relationship_between_subjective_wellness_and_external_training_load_in_elite_English_Premier_League_Goalkeepers_.pdf?utm_source=openai))	[17] [18]
Build strength and power	high	Goalkeeping is strongly power-oriented: you jump, dive, and react explosively, and you also build leg/hip/core strength to produce force quickly and control landings. That’s directly aligned with building strength and power—even without a gym—though you’ll generally improve more if strength training is added. ([link.springer.com](https://link.springer.com/article/10.1007/s40279-018-0977-2?utm_source=openai))	[17] [18] [19]
Challenge myself	high	Being a goalkeeper is demanding mentally and physically: you must stay alert, make split-second decisions, and repeatedly attempt high-risk actions (dives/jumps) under pressure. That “stretching yourself” quality maps well to challenge. ([cris.brighton.ac.uk](https://cris.brighton.ac.uk/ws/portalfiles/portal/37748827/Accepted_Proof_The_relationship_between_subjective_wellness_and_external_training_load_in_elite_English_Premier_League_Goalkeepers_.pdf?utm_source=openai))	[17] [18] [19]
Compete and measure myself	medium	You absolutely compete in matches, and you can measure progress via goals conceded, clean sheets, saves, and decision quality. But at amateur level, those stats may be noisy (team strength, shot volume, defensive organization), and goalkeeper performance is harder to compare objectively than, say, timed running. So the fit is medium-high, and I’m scoring it medium. ([link.springer.com](https://link.springer.com/article/10.1007/s40279-018-0977-2?utm_source=openai))	[17] [18] [19]
Improve agility and coordination	medium	Goalkeepers need quick, coordinated body positioning (footwork, hand/eye timing, body shape during dives) and must adjust rapidly to unpredictable ball flight. That said, “agility” for GK is more about reactive, non-standard movement than repeated direction changes like some field roles, so the fit is medium rather than high. ([link.springer.com](https://link.springer.com/article/10.1007/s40279-018-0977-2?utm_source=openai))	[17] [18]
Improve balance and control	high	A big part of goalkeeping is landing and recovering from awkward movements: stabilizing in a split-second, holding body position before contact, and controlling landings after dives and jumps. Those repeated balance challenges strongly match “balance and control.” ([link.springer.com](https://link.springer.com/article/10.1007/s40279-018-0977-2?utm_source=openai))	[17] [18] [19]
Improve flexibility and mobility	low	Goalkeeping uses a lot of range of motion during dives, but it’s not typically “mobility training.” Unless your practices intentionally include stretching and mobility work, most improvements will be from skill and power rather than big gains in flexibility/mobility. ([link.springer.com](https://link.springer.com/article/10.1007/s40279-018-0977-2?utm_source=openai))	[17] [19]
Improve general health and fitness	high	Even though goalkeepers (GK) don’t cover as much total distance as outfield players, the position still includes frequent high-intensity actions (explosive pushes/quick steps, jumps, dives) plus constant readiness and short recoveries. Over a season of amateur goalkeeping—especially if you train rather than only do matches—this reliably supports a solid baseline of general fitness. ([link.springer.com](https://link.springer.com/article/10.1007/s40279-018-0977-2?utm_source=openai))	[17] [18] [19]
Improve speed and explosiveness	high	Explosiveness is at the core of goalkeeping. Your best actions rely on quick first steps, reactive changes of direction, and rapid acceleration into a dive or set position—so GK training consistently rewards speed and explosiveness more than most other positions. ([cris.brighton.ac.uk](https://cris.brighton.ac.uk/ws/portalfiles/portal/37748827/Accepted_Proof_The_relationship_between_subjective_wellness_and_external_training_load_in_elite_English_Premier_League_Goalkeepers_.pdf?utm_source=openai))	[17] [18] [19]
Learn new skills and master technique	high	Goalkeeping is very technique-heavy: catching/handling, diving mechanics, positioning angles, footwork timing, and reading ball flight. These are learnable skills with clear practice feedback (coaching cues and outcomes), making this a strong match. ([link.springer.com](https://link.springer.com/article/10.1007/s40279-018-0977-2?utm_source=openai))	[17] [19]
Lose weight	medium	Weight loss depends heavily on total calorie burn. Goalkeepers generally run less distance than outfield players, so the match-time calorie burn can be lower. However, the repeated explosive actions and goalkeeper-specific training can still contribute meaningfully—just usually not as strongly as roles with constant running. ([cris.brighton.ac.uk](https://cris.brighton.ac.uk/ws/portalfiles/portal/37748827/Accepted_Proof_The_relationship_between_subjective_wellness_and_external_training_load_in_elite_English_Premier_League_Goalkeepers_.pdf?utm_source=openai))	[18] [19]
Make friends and feel a sense of belonging	high	Soccer (including being GK) is strongly social: teammates train together, communicate frequently, and share match-day experiences. While goalkeeping is a specialized role, you still belong within the team structure, and you interact directly with defenders during play. ([jamanetwork.com](https://jamanetwork.com/journals/jamapediatrics/fullarticle/2734743?utm_source=openai))	[20] [21] [22]
Reduce stress and feel better	medium	Playing soccer is generally good for mood and stress because it combines physical activity with social belonging. Goalkeeping can be emotionally intense (you’re directly involved in critical moments), so it may help as much as other roles for many people, but it’s not uniquely superior just because you’re a GK—so medium alignment. ([jamanetwork.com](https://jamanetwork.com/journals/jamapediatrics/fullarticle/2734743?utm_source=openai))	[20] [21] [22]
Spend time with people I care about	medium	You do spend a lot of time around teammates, but during active play a goalkeeper’s attention is highly focused (and communication is often brief/urgent). So it’s not as naturally “talk while practicing” as lower-intensity sports; it’s medium. ([link.springer.com](https://link.springer.com/article/10.1007/s40279-018-0977-2?utm_source=openai))	[17] [18]

Preferences

Factor	Alignment	Reasoning	Sources
Competition-focused environment	high	Goalkeepers are extremely visible in match results: one goal conceded can dominate evaluation. Amateur leagues still revolve around standings, clean sheets, and match performance, which strongly fits a competition-focused preference.	—
Enjoys contact	medium	You should be comfortable being physically involved (diving, impacts on landing, and occasionally bumping/through-body contact during claims). But the dominant identity is preventing goals, not initiating collisions—so it’s only moderately aligned for someone who specifically enjoys contact.	[23]
Flexible Time Table	medium	You can practice some skills solo (reaction/footwork drills, wall ball handling, stretching/mobility), but meaningful improvement still benefits from team training (crosses/set pieces, defenders’ timing, distribution options) and matches. So flexibility exists, but it’s not fully independent.	—
Indoor setting	none	Standard soccer/goalkeeping is an outdoor, field-based activity. Indoor soccer/futsal does exist, but that’s a different sport/setting and typically different goalkeeping demands.	—
Long steady efforts	low	Goalkeeper performance isn’t mainly defined by long, steady running the way some endurance roles are. Even though you have to be fit for the full match, your key actions are short, irregular events.	[24]
Low impact on joints	low	Goalkeepers make repeated high-impact movements: explosive dives/sprints, frequent jumping (aerial claims), and landings that can load ankles/knees/hips and wrists/shoulders. It’s not joint-gentle compared with low-impact sports.	[25]
Mostly individual	medium	You spend much of the match relatively alone compared with outfield players, and many moments are 1-vs-1 (save situations). However, your effectiveness still depends on team positioning and how defenders play the penalty area, set pieces, and distribution.	[23]
Non-contact	medium	Goalkeeping includes direct physical contests—jumping for high balls, diving, and taking contact when challenging for crosses or through bodies. It’s not a pure contact sport, but it also isn’t “low contact/no contact” in practice.	[23]
Outdoor setting	high	As a goalkeeper, you’re strongly tied to outdoor match conditions (weather affecting balls in flight, visibility, wind/rain, and pitch/stands environment). The “court” is the goal area on a field outdoors, so the role naturally matches an outdoor preference.	—
Playful recreational atmosphere	low	Goalkeeping can be intense and high-responsibility. Even in casual settings, mistakes are costly, and you’re often mentally on-alert—so it usually doesn’t feel like a light, purely social vibe.	—
Routine and structure	medium	There’s structure in training (handling drills, diving/footwork practice, set-piece routines), and within a match you follow repeatable positioning/rest-start patterns. But the match is unpredictable—shots happen at irregular times—so it’s not as routine/predictable as some structured sports.	[23]
Short explosive efforts	high	Goalkeepers often go from stillness to sudden bursts: quick reactions to shots, short sprints off the line, and explosive dives/jumps to reach the ball. The effort pattern is bursty rather than continuous.	[26]
Tactical and strategic	high	A goalkeeper is constantly reading threats: anticipating where the next dangerous ball will come from, choosing whether to stay or come out, organizing defenders, and making tactical decisions on restarts and set pieces.	[23]
Team environment	high	Goalkeeping is highly team-based even though you’re alone in the box: you organize the back line, command the defensive shape, and coordinate restarts/clearing and communication with defenders.	[23]
Technique-heavy	high	This position rewards highly refined technique: catching/handling, footwork on the line, safe diving mechanics, proper positioning before the shot, and distributing the ball accurately.	[23]
Variety and novelty	medium	You face a wide range of shot types (low drives, crosses, one-on-ones) and game states (set pieces, counters). However, the “core actions” of saving/claiming/clearing repeat a lot each match, so it’s moderately varied, not highly novel.	[23]
Water environment	none	Water is not part of soccer’s gameplay environment for goalkeepers.	—

Injuries

Risk

Factor	Value	Definition	Full reasoning	Sources
Achilles tendon pain (tendinopathy)	medium	Pain and irritation in the Achilles tendon at the back of the ankle.	Even though goalkeepers may not run as continuously as outfield players, they repeatedly accelerate, decelerate, and jump/land in the penalty area. Those actions can overload the calf/Achilles—enough to make Achilles tendinopathy a meaningful risk. It’s not the absolute highest compared with hand/finger or shoulder issues, so medium.	[27]
ACL injury	low	A major ligament injury inside the knee, often linked to pivoting, landing, or sudden deceleration.	Soccer has ACL risk, and landing/plant stress can occur when goalkeepers dive or land after saves. Still, compared with high-cutting outfield roles, ACL incidence for goalkeepers is often lower. With no goalkeeper-specific evidence to raise it, the rating is low.	[29]
Ankle sprain	medium	A stretched or torn ankle ligament, usually after the foot rolls awkwardly.	Ankle sprains are a common soccer injury overall. Goalkeepers do experience awkward landings and push-off mechanics and may collide while challenging, creating real exposure. However, compared with midfield/defenders, they’re typically exposed to fewer continuous running/cutting events across matches, so this is medium rather than high.	[30]
Calf strain	none	A pulled or overloaded calf muscle, often felt during pushing off, sprinting, or jumping.	Goalkeepers can strain calves during sudden push-offs, but given the absence of goalkeeper-specific incidence support, risk is none.	[32]
Finger or hand impact injury	high	Pain from jamming, bending, or striking the fingers or hand during sport.	Goalkeepers are structurally exposed to hand/finger trauma because they must contact the ball with their hands and are prone to falls/impacts during saves. Goalkeeper-focused reviews and clinical discussions describe common hand/finger injury mechanisms (e.g., direct finger impact and “mallet finger”-type scenarios). That makes risk high in this role.	[33] [34]
General forearm overuse pain	none	Ongoing forearm pain from repeated gripping, lifting, or arm use when the exact tendon is unclear.	Goalkeeper training repeatedly stresses the shoulder and hand/fingers (including catching, punching, and throwing), whereas the forearm overuse patterns in this taxonomy are typically driven by repetitive gripping/wrist actions. So the expected risk for forearm_overuse_pain is effectively none for a typical central goalkeeper role at moderate play frequency.	—
General foot or ankle pain	medium	Ongoing foot or ankle pain when the exact structure or diagnosis is unclear.	Goalkeepers repeatedly load the foot/ankle through jumping/landing, quick lateral pushes, and short sprints. That provides enough cumulative exposure to make general foot/ankle pain a meaningful risk, but typically not as dominant as hand/finger and shoulder problems. Medium.	[32]
General hip or groin pain	low	Ongoing hip or groin pain when the exact structure or diagnosis is unclear.	Soccer mechanisms (sprinting, bracing in duels, and changes of direction) are plausible for hip/groin pain, but goalkeeper-specific evidence for high hip/groin injury incidence isn’t established in the provided sources. So risk is low.	—
General knee pain	low	Ongoing knee pain when the exact structure or diagnosis is unclear.	Goalkeepers repeatedly land from dives and perform explosive movements that can stress the knee. However, in this injury taxonomy and without goalkeeper-specific incidence evidence, knee pain is best rated low rather than medium/high.	[35]
General lower-back pain	low	Ongoing lower-back pain when the exact source is unclear.	Back pain is plausible from repeated trunk bracing/impacts. But without stronger goalkeeper-specific incidence evidence, it’s low.	[32]
General lower-leg pain	low	Ongoing shin or calf pain when the exact diagnosis is unclear.	Goalkeepers do repeatedly load the lower leg/calf/shin complex through explosive actions. It’s plausible, but not necessarily dominant compared to upper-body goalkeeper injuries, so low.	[32]
General shoulder pain	medium	Ongoing shoulder pain when the exact structure or diagnosis is unclear.	Goalkeepers use the upper extremity frequently for save actions. Evidence in goalkeeper-specific populations shows higher upper-extremity injury involvement and shoulder-related conditions compared to field players. That supports a meaningful (medium) risk for general shoulder pain.	[36]
General wrist or hand pain	medium	Ongoing wrist or hand pain when the exact structure or diagnosis is unclear.	Goalkeeper role causes substantial upper-extremity loading. While specific “general wrist/hand pain” varies by condition, the overall exposure supports medium risk rather than none. Evidence of increased upper-extremity injuries in goalkeepers supports this direction.	[33] [36]
Golfer's elbow	none	Pain on the inside of the elbow linked to overload in the forearm tendons.	Goalkeepers may have arm use, but golfer’s elbow is usually driven by repetitive wrist/forearm flexor work (gripping/throwing patterns won’t be enough to make this a dominant goalkeeper-specific risk). Thus risk is none.	—
Groin strain	low	A pulled or irritated groin muscle, often felt in cutting, sprinting, or kicking movements.	Goalkeepers do make explosive lateral and stopping movements that can stress adductors, but in the absence of stronger goalkeeper-specific incidence data, this remains low.	[32]
Hip flexor strain	none	A strain or overload in the front-of-hip muscles that help lift the leg.	While hip flexors can be stressed during kicking motions and rapid movements, goalkeeper-specific frequency is unclear and likely lower than other hallmark issues (hand/finger/shoulder). Defaulting to none for this specific diagnosis at moderate play.	—
Side-of-hip tendon pain	none	Irritation of the hip or gluteal tendons around the outer side of the hip.	Goalkeepers do load the hip during lateral movements and landing mechanics, yet without evidence of high incidence in goalkeepers for this specific diagnosis, risk is none.	—
Lower-back disc irritation	none	Lower-back pain that may involve irritation of a spinal disc and sometimes pain spreading into the leg.	Without evidence linking goalkeeping to higher incidence of lumbar disc irritation specifically, default to none.	—
Mechanical lower-back pain	none	Common lower-back pain related to movement, loading, stiffness, or irritated supporting tissues.	Plausible mechanisms exist, but because the task asks for evidence-based injury categories and there’s no goalkeeper-specific data in the sources to justify low/medium, the safest default in this framework is none.	—
Meniscus injury	none	Irritation or tearing of the knee cartilage that helps cushion and stabilize the joint.	Meniscus injury mechanisms can occur during planted-foot twisting or contact. While goalkeepers can be involved in awkward landings, there isn’t enough goalkeeper-specific evidence to raise this above none at moderate play frequency.	—
Jumper's knee (patellar tendinopathy)	none	Pain and irritation in the tendon just below the kneecap.	Goalkeepers do jump and dive, but there’s no strong evidence in the sources provided that patellar tendinopathy is a typical goalkeeper-specific outcome. So none.	—
Front-of-knee pain (patellofemoral pain)	none	Pain around or behind the kneecap that often flares with repetitive knee bending.	Without evidence that this is a common goalkeeper injury at moderate frequency, risk is none.	—
Heel pain (plantar fasciitis)	low	Irritation of the tissue under the foot that often causes pain near the heel.	Goalkeepers do land and push off frequently, which can stress the plantar fascia, but without goalkeeper-specific evidence suggesting this is particularly common, the best defensible rating is low rather than medium/high.	[32]
Rotator cuff irritation	medium	Pain and overload in the shoulder muscles and tendons that help control arm movement.	Goalkeeper shoulder demands include repeated overhead/throwing mechanics. Goalkeeper literature specifically points to throwing shoulder dysfunction and rotator cuff strength deficits, supporting meaningful risk for rotator cuff irritation.	[36]
Shin splints	low	Exercise-related pain along the shin that often appears when impact load rises too quickly.	Goalkeepers do face repetitive lower-leg impact, but shin splints are usually more associated with higher running volumes. Without goalkeeper-specific incidence support, low risk is most defensible.	[32]
Shoulder impingement-type pain	medium	Shoulder pain that appears when tissues feel pinched or irritated during arm elevation.	Goalkeeper-specific shoulder dysfunction evidence supports the idea that shoulder pathology is prevalent. Impingement is a plausible shoulder pain mechanism from repetitive overhead positioning and dynamic loading. With medium confidence, risk is medium.	[36]
Shoulder instability or dislocation	none	A shoulder that has slipped out, partly slipped out, or feels unreliable in vulnerable positions.	Instability/dislocation is possible in soccer, but compared with more common goalkeeper issues (shoulder dysfunction, rotator cuff problems, hand/finger trauma), it’s not justified as a common goalkeeper risk category here. So none.	—
Back stress reaction (spondylolysis)	none	A stress injury in the back often linked to repeated extension and rotation loading.	Without strong evidence that goalkeeping at moderate recreational frequency commonly leads to spondylolysis, risk defaults to none.	—
Tennis elbow	none	Pain on the outside of the elbow linked to overload in the wrist and forearm tendons.	While goalkeepers use their arms, the dominant overuse injuries tend to involve the shoulder and hand/finger. Wrist-extensor-dominant repetitive loading isn’t usually the primary mechanism, so risk is none.	—
Shin bone stress injury	none	Stress irritation in the tibia from repeated impact that has outpaced recovery.	While repeated impact could contribute, there’s insufficient evidence that goalkeepers at moderate practice frequency commonly develop tibial stress injuries. Default to none.	[32]
Wrist sprain	medium	A stretched or irritated wrist ligament, often after a fall, impact, or awkward bend.	Goalkeepers are exposed to wrist sprain mechanisms from falls and impact with the hand. However, the most frequent issues are often finger-specific; therefore medium rather than high.	[34]
Wrist tendon pain	none	Irritation of wrist tendons from repeated gripping, racquet use, lifting, or supporting body weight.	Goalkeeping involves repetitive wrist/hand use, but the dominant injury profile is often acute hand/finger trauma and shoulder dysfunction rather than primarily wrist tendinopathy in this taxonomy. With no strong evidence to elevate risk, default to none.	[40]

Prevention

Factor	Value	Definition	Full reasoning	Sources
Achilles tendon pain (tendinopathy)	medium	Pain and irritation in the Achilles tendon at the back of the ankle.	Goalkeeper training includes repeated ankle/calf loading, which can support tendon adaptation if managed. Additionally, soccer neuromuscular warm-ups (FIFA 11+-type) improve ankle/knee control and are linked with lower-limb injury reductions in soccer contexts, providing a meaningful (but not perfect) prevention effect. Hence medium rather than high.	[28]
ACL injury	medium	A major ligament injury inside the knee, often linked to pivoting, landing, or sudden deceleration.	FIFA 11+-type neuromuscular warm-ups have evidence for reducing injury mechanisms in soccer and improving knee/ankle proprioception and control. Goalkeepers still benefit from this. Because ACL mechanisms are still present during dives/landings, set to medium.	[28]
Ankle sprain	medium	A stretched or torn ankle ligament, usually after the foot rolls awkwardly.	FIFA-style neuromuscular injury-prevention approaches have evidence for reducing ankle injuries in football contexts. In goalkeepers, this translates into a meaningful prevention effect, though not complete due to match/landing unpredictability. So medium.	[31]
Calf strain	none	A pulled or overloaded calf muscle, often felt during pushing off, sprinting, or jumping.	No specific preventive evidence assumed beyond general fitness; none.	—
Finger or hand impact injury	medium	Pain from jamming, bending, or striking the fingers or hand during sport.	Some evidence-informed and practical measures (hand protection, technique, and readiness) can reduce hand injuries, but there’s still high exposure because goalkeepers must use their hands in live play. That supports medium rather than high prevention.	[34]
General forearm overuse pain	none	Ongoing forearm pain from repeated gripping, lifting, or arm use when the exact tendon is unclear.	There’s no clear evidence that goalkeeper-specific activity protects against forearm overuse pain, so this is set to none.	—
General foot or ankle pain	low	Ongoing foot or ankle pain when the exact structure or diagnosis is unclear.	Because general foot/ankle pain is broad and not reliably prevented by goalkeeper role alone (and because normal play both causes and conditions load), the prevention effect is uncertain. Set to low.	—
General hip or groin pain	none	Ongoing hip or groin pain when the exact structure or diagnosis is unclear.	No strong injury-specific prevention evidence is available for this category for goalkeeping role alone; none.	—
General knee pain	none	Ongoing knee pain when the exact structure or diagnosis is unclear.	Without assuming knee-focused strength/rehab beyond normal practice, prevention isn’t reliably injury-specific; none.	—
General lower-back pain	none	Ongoing lower-back pain when the exact source is unclear.	Without assuming back-focused conditioning programs, set to none.	—
General lower-leg pain	none	Ongoing shin or calf pain when the exact diagnosis is unclear.	Without assuming targeted lower-leg conditioning programs outside normal soccer, prevention is not injury-specific; none.	—
General shoulder pain	medium	Ongoing shoulder pain when the exact structure or diagnosis is unclear.	While prevention is not guaranteed by simply playing, goalkeeper-specific repetitive throwing requires functional shoulder control and tissue tolerance. Also, warm-ups used in soccer programs can improve neuromuscular readiness. Because the role inherently exposes the shoulder, prevention is meaningful but not absolute, so medium.	[36]
General wrist or hand pain	low	Ongoing wrist or hand pain when the exact structure or diagnosis is unclear.	Prevention depends on hand protection/technique quality and sometimes equipment; since those are not guaranteed “extra” programs here, prevention is only low.	[37]
Golfer's elbow	none	Pain on the inside of the elbow linked to overload in the forearm tendons.	No goalkeeper-specific preventive link is established for this specific diagnosis; set to none.	—
Groin strain	none	A pulled or irritated groin muscle, often felt in cutting, sprinting, or kicking movements.	Without assuming dedicated adductor-specific training outside normal play, prevention isn’t supported; none.	—
Hip flexor strain	none	A strain or overload in the front-of-hip muscles that help lift the leg.	No goalkeeper-specific prevention evidence assumed; none.	—

Lower-back disc irritation	none	Lower-back pain that may involve irritation of a spinal disc and sometimes pain spreading into the leg.	Set to none.	—
Mechanical lower-back pain	none	Common lower-back pain related to movement, loading, stiffness, or irritated supporting tissues.	No specific preventive evidence for this diagnosis assumed; none.	—
Meniscus injury	none	Irritation or tearing of the knee cartilage that helps cushion and stabilize the joint.	Meniscus prevention typically requires specific technique and neuromuscular/strength strategies not assumed here; none.	—

Front-of-knee pain (patellofemoral pain)	none	Pain around or behind the kneecap that often flares with repetitive knee bending.	Set to none.	—
Heel pain (plantar fasciitis)	low	Irritation of the tissue under the foot that often causes pain near the heel.	With no assumption of extra foot-specific stretching/strengthening beyond normal team training, prevention is uncertain. Low.	—
Rotator cuff irritation	medium	Pain and overload in the shoulder muscles and tendons that help control arm movement.	Because the shoulder is repeatedly loaded, prevention is limited by exposure. Still, neuromuscular warm-ups and appropriate preparation can reduce injury mechanisms, giving a medium prevention level.	[38]
Shin splints	none	Exercise-related pain along the shin that often appears when impact load rises too quickly.	Shin splints depend strongly on load progression and technique/footwear factors; none assumed here; none.	—
Shoulder impingement-type pain	low	Shoulder pain that appears when tissues feel pinched or irritated during arm elevation.	Injury-specific prevention for impingement usually requires targeted shoulder mobility/control and strength—none of which is guaranteed by “playing the sport.” Since there is still some general conditioning and warm-up benefit, it’s low rather than none.	[39]
Shoulder instability or dislocation	none	A shoulder that has slipped out, partly slipped out, or feels unreliable in vulnerable positions.	Prevention would require shoulder stabilization training beyond normal play; none assumed, so none.	—
Back stress reaction (spondylolysis)	none	A stress injury in the back often linked to repeated extension and rotation loading.	Set to none.	—
Tennis elbow	none	Pain on the outside of the elbow linked to overload in the wrist and forearm tendons.	No injury-specific evidence-based preventive effect is expected for this role beyond general fitness, so none.	—

Wrist sprain	low	A stretched or irritated wrist ligament, often after a fall, impact, or awkward bend.	Without assuming extra specialized prevention training beyond normal warm-ups, prevention is limited. Low.	—
Wrist tendon pain	none	Irritation of wrist tendons from repeated gripping, racquet use, lifting, or supporting body weight.	Prevention for tendinopathy would require targeted tendon loading/mobility/technique optimization beyond normal play; none assumed, so none.	—

Heal

Factor	Value	Definition	Full reasoning	Sources
Achilles tendon pain (tendinopathy)	low	Pain and irritation in the Achilles tendon at the back of the ankle.	Achilles tendinopathy healing typically requires symptom-guided tendon load management. With only “regular goalkeeping practice” assumed (no extra rehab), the net expected benefit is small and could easily be neutral-to-negative, so low.	—
ACL injury	low	A major ligament injury inside the knee, often linked to pivoting, landing, or sudden deceleration.	ACL recovery generally requires structured rehabilitation and often surgical/medical management. Without that being assumed, continuing play isn’t expected to speed healing; small benefits are only possible for very mild/managed situations. Low.	—
Ankle sprain	low	A stretched or torn ankle ligament, usually after the foot rolls awkwardly.	Sprain healing typically needs progressive protection and rehab. Without assuming targeted rehab beyond normal play, continued goalkeeping on a sprained ankle is more likely to delay than accelerate recovery, but mild cases could have minimal benefit. Therefore low (not none).	—
Calf strain	none	A pulled or overloaded calf muscle, often felt during pushing off, sprinting, or jumping.	Calf-strain healing typically requires progressive loading and may be aggravated by ongoing explosive play; none assumed, so none.	—
Finger or hand impact injury	low	Pain from jamming, bending, or striking the fingers or hand during sport.	Hand/finger injuries heal through protection and progression. Without assuming splinting/rest and rehab beyond normal play, continued goalkeeping (hand contact) is more likely to maintain or worsen symptoms. At most there’s a small chance of benefit for very mild injuries, so low.	—

Without forearm-specific load management/rehab assumed beyond normal play, continuing soccer goalkeeping isn’t expected to provide a positive healing effect for forearm overuse pain.	—
General foot or ankle pain	none	Ongoing foot or ankle pain when the exact structure or diagnosis is unclear.	Many foot/ankle overuse pains require symptom-guided load reduction and targeted rehab. With no such extra rehab assumed, normal play isn’t expected to provide positive healing, so none.	—
General hip or groin pain	none	Ongoing hip or groin pain when the exact structure or diagnosis is unclear.	Groin/hip pain usually needs targeted load management/rehab. Without assuming those extras, there’s no basis for positive healing, so none.	—

General lower-leg pain	none	Ongoing shin or calf pain when the exact diagnosis is unclear.	Healing usually depends on diagnosing the cause and managing load; normal play alone isn’t expected to help reliably, so none.	—
General shoulder pain	low	Ongoing shoulder pain when the exact structure or diagnosis is unclear.	Goalkeeper actions can be provocative (high-velocity throwing/saving). Without assuming shoulder rehab/load modification beyond normal practice, the expected healing benefit is small and may be neutral-to-negative. Therefore low.	—
General wrist or hand pain	none	Ongoing wrist or hand pain when the exact structure or diagnosis is unclear.	Healing depends on protecting the painful tissue and sometimes immobilization/rehab; that’s not assumed here. With continued hand contact, positive healing from normal play isn’t expected—so none.	—
Golfer's elbow	none	Pain on the inside of the elbow linked to overload in the forearm tendons.	Healing needs targeted tendon load management and symptom control; normal practice is unlikely to provide that reliably, so none.	—

Rotator cuff irritation	low	Pain and overload in the shoulder muscles and tendons that help control arm movement.	Rotator cuff irritation healing typically relies on symptom-guided load modification and often targeted rehab. Normal goalkeeping likely continues provocative loading (throws/saves), so only low positive healing is expected.	—

Past-sport transfer logic

Past sport	Average correlation (success)	Std dev	Correlation reasoning	Correlation sources
american-football-defensive-back	0.18	0.12	Defensive back success should correlate modestly with soccer goalkeeper success because both demand fast reactions, anticipation, and strong defensive positioning under pressure. However, goalkeeper performance is highly technique-specific (dive timing and mechanics, catching/boxing, shot-handling under spin/deflections) and depends on goalkeeper-specific distribution decisions. Defensive back training also emphasizes reading routes/space, whereas goalkeepers must read shot release and ball trajectory. These specificity and cue-set gaps keep the correlation from being high, resulting in a low-to-moderate positive correlation with meaningful variance by individual learning speed and prior goalkeeper experience.	[41] [42] [43] [44] [45]
american-football-line-player	0.29	0.14	We’re estimating the correlation between: (A) success as an American football line player (mass/leverage/power; collision-heavy; opponent-driven chaos but not the same action system as shot-stopping) and (B) success as a soccer goalkeeper (crease shot-stopping; positioning/coverage; dive timing; relies heavily on information pickup, anticipation, and decision timing). The correlation should be clearly non-zero because both roles require: (1) operating under high time pressure, (2) making fast decisions based on visual information, and (3) maintaining performance in chaotic, opponent-driven contexts. Football evidence indicates shared perceptual/visual and reaction-related capabilities across positions (not purely role-specific). ([sciencedirect.com](https://www.sciencedirect.com/science/article/pii/S1469029214001046?utm_source=openai)) However, it should not be high because goalkeeper success also depends on sport-specific cueing and action systems—especially the goalie’s information pickup and gaze/quiet-eye-like strategy and the biomechanics of diving/positioning on a soccer field. Goaltending research emphasizes that information pickup and anticipatory strategies dominate, which are only partially transferable from football line play. ([sciencedirect.com](https://www.sciencedirect.com/science/article/pii/S1469029214001046?utm_source=openai)) Therefore a moderate correlation around the upper-0.2s to low-0.3s is realistic, with substantial uncertainty. Chosen point estimate: r ≈ 0.29, std dev ≈ 0.14.	[46] [47] [48] [49]
american-football-linebacker-tight-end	0.17	0.1	Linebacker/tight end success should correlate weakly-to-modestly with soccer goalkeeper success because both are defensive roles that benefit from: quick anticipation, strong body control under pressure, and the ability to maintain positioning/effort during chaotic play. However, a goalkeeper’s performance is heavily constrained by goalkeeper-specific perceptual-motor and technique determinants: diving/shot-react mechanics, hand/finger positioning, catching vs punching choices, and often distribution/first-contact skills. Those are not central in LB/TE, where outcomes are dominated by tackling/blocking leverage and short traffic movement rather than repeatable save mechanics. So the carryover is positive but limited: football defensive instincts and athletic balance help you start faster, but most variance in GK success comes from goalkeeper-specific diving and ball-handling practice.	[50] [51] [52]
american-football-quarterback	0.3	0.12	We estimate the correlation between success as an American football quarterback and success as a soccer goalkeeper, excluding physique/proportional traits. Why it’s above low baseline (raises correlation): - Shared perceptual-cognitive core: QBs and goalkeepers both rely heavily on reading the situation early, anticipating trajectories/pressure, and making rapid, correct choices based on visual information. - General expertise translates to learning efficiency: QB training tends to refine scanning, attentional control, and adaptation under pressure—skills that can speed early GK skill acquisition. Why it’s not high (lowers correlation): - Action-affordance mismatch: QB success is dominated by throwing mechanics and play execution; GK success is dominated by shot-stopping mechanics (diving/catching/positioning) with different timing constraints. - Goalkeeper-specific technical sequences matter: Specific reaction + action patterns are goalkeeper-critical, and these are not directly practiced as a QB. - Decision-making transfer attenuates across dissimilar sports: even when both involve “deciding,” the response options and movement execution differ. Bayesian calibration to a single number: starting from a dissimilar-sport baseline (~0.2–0.3) and moving upward slightly because anticipation/perception overlap is meaningful for goalkeeping, but moving downward relative to “similar-position” transfers due to goalkeeper-specific diving/shot-stopping mechanics. This yields ~0.30 with ~0.12 uncertainty.	[53] [54] [55] [56] [57]
american-football-receiver-running-back	0.15	0.1	Receiver/running back performance should correlate slightly with soccer goalkeeper success because both roles rely on (1) tracking a ball rapidly, (2) reacting quickly to changing trajectories, and (3) explosive movement and balance to get into the right position. However, goalkeeper performance depends strongly on specialized technical and tactical systems: dive mechanics, hand positioning/angles, choosing catch vs parry vs punch, aerial timing/handling, starting/starting-steps and lateral edge work specific to goalkeeping, and unique distribution/communication responsibilities. WR/RB roles don’t systematically train these goalkeeper-specific mechanics or the decision loops tied to penalty-area play. So the carry-over should be modest—around the mid-teens (≈0.15) with meaningful uncertainty.	[58]
athletics-distance	0.05	0.03	Distance-running success should show only a slight relationship with later soccer goalkeeper success. Some general components transfer: athletes who do well in distance events often have better training consistency, aerobic/anaerobic base for repeated high-intensity actions, fatigue resistance, and can maintain concentration during intermittent periods. However, the dominant determinants of goalkeeper performance are highly sport- and technique-specific: rapid visual tracking and reaction to shots, diving/catching/deflection mechanics, positioning and angle selection in the penalty area, and read-and-react decision-making. These have minimal overlap with distance-running technique. Therefore the expected skill-based correlation remains low but not exactly zero, plausibly around a mean of ~0.05 with moderate uncertainty (about 0.02–0.10).	[59]
athletics-jumps-high-jump	0.1	0.08	High-jump performance should correlate only weakly with soccer goalkeeper success. There is some transferable, technique-adjacent athletic component: explosive leg power and strong body control for jumping and safe landings can help with diving mechanics and recovering position. However, goalkeeper success is dominated by highly specific open-skill perceptual and technical demands—reading the shooter, timing, catching/deflecting technique with the hands/feet, and making correct decisions under live game cues. These are largely absent from high jump. Additionally, the movement patterns differ substantially (vertical clearance vs reactive lateral/low dives and penalty-area positioning). Therefore the expected correlation is small and variable.	[60] [61] [62]
athletics-jumps-long-triple-jump	0.1	0.09	Long jump/triple jump performance reflects explosive lower-body power, elastic stiffness/recoil, and whole-body coordination that can provide a modest athletic advantage for a soccer goalkeeper’s dive mechanics, push-offs, and recovery speed. However, goalkeeper performance is dominated by highly sport-specific technical skills: shot/ball reading, catching and handling technique, positioning to reduce angles, footwork patterns inside the box, and distribution/decision-making. Since these core learning components are largely non-overlapping with jumping-event training, the expected carry-over should be small but positive, with substantial individual variability.	[63] [64] [65]
athletics-jumps-pole-vault	0.12	0.09	Pole vault should have a small positive correlation with soccer goalkeeper success because both reward general athletic qualities: explosive leg power, excellent balance/aerial-body control, and the ability to re-stabilize quickly after dynamic movement. However, goalkeeper performance is dominated by soccer-specific perceptual and technical-tactical skills (reading shots, diving/landing mechanics in soccer contexts, catching/handling, positioning/angles, and decision-making). Pole vault’s unique motor components (pole plant/inversion and vault landing constraints) do not directly train those. Therefore the expected carryover is modest (roughly ~0.05–0.20), centered around ~0.12 with moderate variance.	[66] [67] [68]
athletics-middle-distance	0.07	0.04	Athletics middle distance and soccer goalkeeping have minimal direct technical overlap. Middle-distance excellence is driven mainly by aerobic pacing and running economy, while goalkeeping success is driven by sport-specific determinants: shot-reading, reaction/timing, dive/save mechanics, penalty-area positioning, and soccer-ball distribution with precise footwork/handling. Any carry-over is mostly indirect (conditioning, coordination, and maintaining readiness across a long match). With goalkeeper proportion traits excluded, the expected correlation remains small but slightly positive, about ~0.07.	[69] [70] [71] [72] [73]
athletics-sprints-hurdles	0.12	0.07	Sprint and hurdle performance should have only a small relationship with soccer goalkeeper success. There is some technique-relevant overlap through explosive first steps, leg stiffness, and rapid repositioning. However, goalkeeper performance is dominated by ball-specific perceptual skills (reading shot direction, timing), save technique (diving/catching/deflecting mechanics), and distribution/decision-making—skills not built in sprints/hurdles. Therefore the carry-over is expected to be modest with meaningful individual variance depending on whether the athlete also has prior ball-skill exposure.	[74] [75] [76]
athletics-throws-discus	0.09	0.05	Discus excellence reflects rotational strength, leverage, rhythm/timing, and efficient whole-body sequencing into a ballistic release. A soccer goalkeeper also benefits from balance, body control, and explosive/reactive movement (lateral pushes, dive initiation, and recovery), so there is a small positive carry-over in general athletic coordination. However, goalkeeper success is largely determined by goalkeeper-specific technical skills (set-body/ready position, dive mechanics, catching/handling, parry/rebound control) and sport-specific perceptual skills (reading shots, anticipating trajectories, positioning on crosses). Those are not well trained by discus. Therefore the expected relationship should be small positive rather than moderate. A realistic Bayesian estimate is ~0.09 average correlation with std dev ~0.05, reflecting variability in whether athletes also play soccer or do comparable catching/goalkeeper-style training beyond discus.	[77] [78] [79]
athletics-throws-hammer-throw	0.06	0.04	Hammer throw success indicates strong whole-body coordination, dynamic balance, and efficient force production. Those can modestly help a soccer goalkeeper with athletic movement quality, explosive dives, and maintaining control through unpredictable body orientations. However, goalkeeper performance is heavily driven by soccer-specific perceptual and technical skills: reading the game/shot, tracking the ball, positioning in the box, and executing repeatable save actions with the constraints of gloves/footwork and live match timing. Hammer throw’s implement-leverage throwing technique does not train these key shot-stopping determinants. Therefore only a small positive correlation is expected.	[80] [81]
athletics-throws-javelin	0.09	0.06	Javelin success correlates with good explosive whole-body coordination and kinetic-chain sequencing (legs→trunk→shoulder/arm) plus upper-body power, which can slightly help an incoming soccer goalkeeper with general athletic execution (e.g., reaching/upper-body force for saves, quick readiness, safe landing mechanics). But elite goalkeeper performance is driven mainly by soccer-specific perceptual-motor and technical skills: reading/anticipating shots, correct positioning and dive selection, repeatable shot-stopping mechanics, catching/boxing and distribution choices, and lateral movement timing in response to a continuously moving ball and attacker. Because javelin’s core technique is a runway-to-release throwing action (and not reactive save technique with a ball in play), the overlap is limited. Therefore the expected carry-over is small but positive—around low ~0.1 on average, with modest spread.	[82]
athletics-throws-shot-put	0.08	0.07	Shot put success indicates maximal whole-body force production, strong trunk bracing, and coordinated explosive movement. These can help a soccer goalkeeper with general physical capabilities: getting off the ground quickly, maintaining alignment, and stabilizing during jumps/dives. However, goalkeeper success is dominated by goalkeeper-native perceptual-motor skills: tracking shots early, diving/catching technique, positioning within the area, handling crosses, and rapid decision-making under unpredictable live play. Those learned skills overlap only indirectly with shot put. Therefore the expected correlation should be small but slightly positive, with meaningful individual variability depending on prior ball/goalkeeping experience and how quickly the athlete acquires goalkeeper-specific reaction and technique.	[83] [84] [85] [86]
badminton	0.06	0.04	Badminton should have a modest positive correlation with soccer goalkeeper success because both require excellent visual tracking of an incoming projectile, quick perception–action timing, and rapid lateral/forward repositioning to get into the save position. However, goalkeeper performance is heavily dependent on soccer-specific skills: handling mechanics (catch vs punch), dive and landing mechanics on pitch surfaces, reading kicking angles and spins shaped by the foot/ball dynamics, communication/commanding the box, and penalty-area positioning rules. Since badminton doesn’t train those directly, the correlation should stay small rather than moderate. A plausible estimate is ~0.03–0.10 with an average around ~0.06.	[87]
baseball-catcher	0.2	0.1	Baseball catcher success should have a modest positive relationship with soccer goalkeeper success because both are shot-stopping roles that require rapid visual tracking, anticipation of where the ball will arrive, and technical composure under pressure. Transferable components: - Reading a fast-moving ball early and reacting quickly - Maintaining a consistent pre-action routine (set/ready posture, timing) - Defensive organization habits: staying mentally “in the moment” and communicating - Some receiving/blocking coordination concepts (body positioning behind the ball) Why the correlation is limited: - Soccer goalkeeper performance depends heavily on soccer-specific mechanics: diving/catching/boxing technique, positioning to different shot angles, and especially footwork/recovery on a grass/turf surface. - Ball behavior and shot geometry differ substantially (puck-like skids vs kicked/spun ball on turf; low-driven trajectories; rebounds from posts/crossbars). - Catcher receiving/blocking in baseball is from a crouch with hand/arm timing against pitches, which only loosely maps to goalkeeper movement paths, angles, and distribution/clearance mechanics. So expect a modest positive correlation, with fairly wide individual variation: some catchers transition well due to exceptional reaction/receiving mechanics and comfort in the goal area, while others are limited by the soccer-specific goalkeeper technique gap.	[88]
baseball-field-player	0.18	0.1	Baseball field players and soccer goalkeepers overlap mainly in reactive perception and defending against a fast-moving ball: tracking trajectory, anticipating shot direction, and reacting quickly in high-pressure moments. But soccer goalkeeping is technique-specific: goalkeeper distribution/footwork, diving/landing mechanics with soccer-ball physics, aerial and one-on-one positioning, handling vs punch choices, and save selection based on soccer-specific shot types. Those core motor patterns are not trained by baseball fielding. So carryover should be modest rather than high. I estimate ~0.18 average with ~0.10 standard deviation, reflecting that some good field players transfer well (great tracking/catching and quick learning), while others struggle with soccer-ball dynamics and goalie-specific footwork/handling decisions.	[89] [90]
baseball-pitcher	0.16	0.08	Pitcher → soccer goalkeeper should have a modest positive carryover. Shared transferable elements are mainly general perceptual-motor and psychological skills: tracking a rapidly moving ball, anticipating trajectory, and executing a precise movement under high stakes. But goalkeeper performance is strongly shaped by soccer-specific technique and positioning: reading the shooter’s body/ball situation in a different context, diving and recovery mechanics, aerial ball handling, catching under flight/spin differences, and controlling the penalty area. Pitching mechanics (overhand throwing delivery and pitch command) do not map directly onto these goalkeeper actions. With body-proportion/trait effects excluded, there’s still meaningful-but-limited overlap, so an average in the mid-teens is plausible (std dev reflecting variability across individuals’ catching/athletic background).	[91] [92] [93]
basketball-big	0.2	0.08	The expected correlation is small-to-modestly positive. Basketball Big can transfer some general defensive cognition—reacting to a ball in space, reading threat direction, and positioning under pressure. However, goalkeeper success depends heavily on highly specific technique (save mechanics on feet/diving, catching/deflecting with the hands under soccer conditions, and distribution patterns). Since Basketball Big does not develop those systems as core skills, the predictive value remains limited and stays in the low-to-mid 0.2 range.	[94] [95]
basketball-guard	0.18	0.12	Basketball guards and soccer goalkeepers share some transferable components: tracking an incoming ball, anticipating shots, making fast position adjustments, and reacting under pressure. However, goalkeeper performance is dominated by soccer-specific technique: setting the correct angle and starting position, diving/catching mechanics under different shot heights, handling/rebounding rules, aerial judgment, and goalkeeper distribution. Those core mechanics are not learned in basketball guard play. Because we exclude physique/proportion advantages, only the perceptual/reactive and general movement-control aspects remain as transferable skill. That produces a modest positive correlation, estimated around ~0.18 with wide individual variation.	[96] [97]
basketball-wing	0.12	0.1	Basketball wing excellence should have a small positive relationship with soccer goalkeeper success because both benefit from fast perception-action coupling and coordinated hand/arm responses. However, goalkeeper performance is heavily determined by soccer-specific technique (diving/landing angles, penalty-area positioning, ground footwork) and the way the ball moves in soccer. Therefore the carry-over is limited. Estimated average correlation ~0.12 with uncertainty ~0.10.	[98] [99] [100] [101]
boxing	0.22	0.12	Boxing should show a moderate positive correlation with soccer goalkeeper success mainly through transferable “reactive combat sport” skills: composure under direct threat, quick response habits, and tracking a fast-moving opponent/target. However, goalkeeping performance is dominated by soccer-specific technical primitives—correct positioning relative to the ball, dive/landing mechanics, catching/deflecting technique, handling traffic/through-balls, and decision-making for distribution. Boxing’s striking/guard skills do not train these primitives directly. Therefore, the correlation should be modest (not high), with substantial variance depending on how quickly the athlete acquires soccer goalkeeper technique.	[102] [103] [104] [105] [106]
climbing-bouldering	0.12	0.1	Bouldering performance reflects strong body tension/bracing, balance, proprioception, and coordinated movement execution in awkward high-load positions. Those general technique-like enablers transfer to a soccer goalkeeper as improved stability in the set position, better control during reactive re-positioning, and more efficient body alignment for drops/dives. However, goalkeeper performance is heavily determined by sport-specific determinants: tracking the ball from a kick, positioning to reduce angles, catching/handling technique, and dive/landing timing that matches soccer shot trajectories. Bouldering does not train these goalkeeper-specific ball-interaction and decision loops. Therefore the carryover should be positive but still modest, with substantial variability depending on how quickly the athlete acquires soccer-specific keeping skills.	[107] [108] [109]
climbing-lead	0.08	0.06	Lead climbing success is driven by movement economy, balance/proprioception, and keeping precise body positioning as grip/forearm fatigue and pump discomfort increase. Soccer goalkeeper success depends heavily on very specific, sport-reaction and interaction skills: reading shots/angles in real time, hand-eye timing for saves, catching/boxing technique, explosive diving and recovery mechanics, and positioning/decision-making with live play and ball distribution. Overlap is mainly general (coordination, balance, and staying technically consistent when tired). Because lead climbing does not meaningfully train the goalkeeper’s key “react to a fast moving ball with a stickless body” mechanics or soccer-specific footwork and reads, the expected correlation remains low. A realistic Bayesian-style estimate is therefore ~0.08 average correlation with moderate uncertainty (~0.06).	[110]
climbing-speed	0.12	0.08	Speed climbing performance reflects explosive upward acceleration, tight body tension control, balance, and the ability to execute repeatable fast movements under time pressure. A soccer goalkeeper also needs quick first movements, strong balance, and rapid recovery after diving/setting. However, goalkeeper performance is dominated by soccer-specific determinants: reading shot cues, positioning in the box, shot-stopping technique (hands/body angle), catching timing, and distribution/footwork. These have low overlap with speed climbing’s hold-to-hold vertical sprint mechanics. Therefore the carry-over should be small but above zero—around ~0.08–0.15, centered near ~0.12.	[111] [112] [113]
cricket-all-rounder	0.12	0.08	Cricket all-rounder success should have a small positive correlation with soccer goalkeeper success mainly through shared perceptual-motor skills: tracking a fast projectile, anticipating shot direction, and reacting quickly during high-leverage moments. However, soccer goalkeeping is highly technique-specific—box positioning, dive/footwork mechanics, handling/1v1 cues, and distribution under soccer rules are not meaningfully developed in cricket. With reach/size effects excluded, the remaining learnable overlap is modest, so the expected correlation is low-to-mid ~0.12.	[114] [115] [116] [117] [118]
cricket-batter	0.26	0.1	Cricket batter success depends strongly on perceptual timing (tracking a fast ball early), hand–eye coordination, and stable lower-body control to execute repeatable actions under pressure. Soccer goalkeeper success also depends heavily on perceptual tracking and rapid reaction timing, plus coordinated whole-body positioning to intercept high-speed shots. Shared components therefore include: early ball reading, visual tracking, coordination of eyes-hands-body, and performing under high-pressure moments. However, most determinants for a top goalkeeper are sport-specific learned motor programs: diving/landing mechanics, shot-stopping technique at specific angles and heights, aerial catching/claiming, close-range positioning, dealing with deflections/rebounds under soccer rules, and distribution footwork/throws/kicks. Cricket batting does not meaningfully train these goalkeeper-specific mechanics. So the correlation should be clearly positive but not very high—around the mid-0.2s—with substantial scatter due to specialization and prior exposure to goalkeeper-type training.	[119]
cricket-bowler	0.12	0.09	Cricket bowler → soccer goalkeeper should be weak-to-modestly positive. Direct technique transfer is limited because bowling’s core learned motor program (overarm projectile delivery) differs from goalkeeper success factors (save mechanics, diving/footwork, penalty-area positioning). The main transferable advantages are higher-level perception-action skills: reading ball-release cues and tracking trajectory early, plus general match composure and the ability to repeat technical actions under pressure. Because goalkeeper performance is still dominated by goalkeeper-specific mechanics, the ceiling is capped. A Bayesian point estimate around 0.12 with std dev ~0.09 reflects “small head start via anticipation/repeatable execution, but limited direct technique mapping.”	[120] [121] [122] [123] [124]
cricket-wicketkeeper	0.2	0.12	Cricket wicketkeeper success should correlate moderately with soccer goalkeeper success because both are specialized reactive roles built around tracking an incoming ball early and making fast, reliable saves from a ready posture. However, soccer goalkeeper performance is strongly governed by soccer-specific technique—diving/landing mechanics, positioning in the penalty area, handling/boxing under different shot types, and distribution footwork—plus different ball dynamics. Since wicketkeeping doesn’t train these directly, the carryover should be limited. Net expectation: a modest positive correlation around ~0.20.	[125] [126] [127] [128]
cycling-mountain-bike-cross-country	0.06	0.06	Cycling (mountain bike cross-country) should have a very small positive correlation with future soccer goalkeeper success (ignoring body-size traits). The carry-over is mainly general athletic: balance/proprioception, body control, and staying technically coordinated under fatigue. However, goalkeeper success is highly soccer-specific and perceptual: catching/claiming timing, dive/landing mechanics, shot reading, and positioning with the ball in play. Those determinants are not trained in MTB XC, so the correlation remains near zero rather than moderate.	[129] [130] [131]
cycling-road-climber	0.03	0.05	Cycling road climbers are specialized for sustained aerobic power-to-weight and pacing. Soccer goalkeepers are specialized for sport-specific perceptual-motor skills—reacting to shots, positioning in the penalty area, diving/landing technique, and ball-handling/distribution timing—plus frequent explosive lateral movements. Because these determinants overlap only weakly with cycling climbing technique, the expected carry-over is very small but not exactly zero due to indirect conditioning and balance. Substantial between-person variability is expected depending on prior goalkeeper/ball-sports exposure.	[132] [133] [134] [135]
cycling-road-sprinter	0.08	0.07	Cycling road sprinter success should have a weak positive relationship with soccer goalkeeper success (technique/skill only, excluding physique). Some general attentional sharpness and ability to perform under intense, repeated effort transfers. However, goalkeeper success is dominated by highly specific skills—diving/shot-tracking mechanics, penalty-area positioning, and handling timing—which have limited overlap with cycling sprint technique. Thus the expected carry-over is small, around ~0.08, with moderate uncertainty.	[136] [137] [138] [139]
cycling-road-time-trialist	0.09	0.1	Cycling road time-trial success should have only a small positive relationship with soccer goalkeeper success. The overlap is mostly general: aerobic/threshold fitness for match-related movement volume, leg strength for jumping/recovery, and mental discipline for training. However, goalkeeper performance is dominated by highly sport-specific perceptual-motor skills—reading shot cues, positioning to reduce angles, immediate reaction timing, and precise diving/landing and catching/deflecting technique with the ball. Since TT cycling does not meaningfully train those reactive, ball-specific patterns, most variance in goalkeeper outcomes should be largely unrelated to TT performance, keeping the correlation low with substantial between-athlete variability.	[140] [141] [142]
cycling-track-endurance	0.05	0.05	Cycling endurance should have only a very small positive relationship with soccer goalkeeper success. Both share general athletic readiness: being fit for repeated intense actions, staying coordinated across a match, and having a lower-body force base. But goalkeeper performance is dominated by soccer-specific perceptual/technical skills: reading shot trajectories, reactive lateral positioning, dive timing/angle execution, catching/deflection technique, aerial/1v1 positioning, and ball handling/distribution under pressure. Track endurance cycling does not build these save-specific skills. So the carry-over correlation should be near the low end for different sports pairings. A realistic estimate is ~0.00–0.10, with an average around 0.05 and moderate uncertainty.	[143]
cycling-track-sprint	0.05	0.11	Technique-only carry-over from cycling sprint track to soccer goalkeeper should be weak. Some general neuromuscular qualities (explosive leg drive, repeated intensity readiness) can help with short reaction bursts and recovery steps. However, goalkeeper performance is dominated by soccer-specific skills—shot-stopping and dive mechanics, catching/deflection technique, positioning/angle judgment, and reading unpredictable shot trajectories and rebounds. Those are not meaningfully trained by velodrome sprint cycling, so the expected correlation stays only slightly above zero. A plausible estimate is ~0.05 with moderate uncertainty (~0.11).	[144] [145] [146]
fencing-epee	0.12	0.08	Epee-to-soccer-goalkeeper should be modestly positive. A strong epee fencer often has excellent read-react timing, distance/angle judgment, and coordinated whole-body positioning—skills that can help with early shot anticipation and getting set for dives/blocks. But elite goalkeeping depends heavily on soccer-specific tool mechanics and constraints: catching/handling the ball under different trajectories, diving/landing technique on the turf, distribution/footwork specific to goalkeeper play, and understanding keeper positioning within soccer systems. Those are not trained by epee blade-touch distance work. Therefore the technique carry-over is limited, yielding an expected correlation around ~0.12 with moderate scatter.	[147] [148] [149]
fencing-foil	0.22	0.14	Foil fencing should correlate positively with soccer goalkeeping success because both depend on broadly transferable technique-neutral factors: early anticipation of the opponent’s intent, distance/positioning judgment, explosive reactive timing, and staying composed through many discrete high-stakes actions. The correlation is not high because goalkeeping performance is dominated by soccer-specific ball-handling and locomotion demands: tracking a real ball with varying flight/spin, executing correct dive/footwork mechanics within the penalty area, and using sport-specific save/deflection/catching technique. Foil’s lunge/point-control against a non-ball target only indirectly overlaps. So a modest-to-moderate positive correlation with substantial variance is the most realistic expectation.	[150] [151] [152]
fencing-sabre	0.16	0.13	Fencing sabre and soccer goalkeeping overlap in general defensive skills: fast reading of an attacker’s intention, quick reaction, and the ability to explode into the correct direction with good balance while maintaining technical discipline. These can create a modest positive association. However, goalkeeper “how good you are” is dominated by soccer-specific mechanics: saving technique with hands/feet at different shot angles, diving and positioning within the penalty area, handling different ball trajectories (spin/bounce), and distribution timing/accuracy. Those key determinants are not meaningfully trained in sabre fencing. With much of the outcome variance coming from missing sport-specific skills, the correlation should remain low-to-moderate rather than high.	[153]
field-hockey-goalkeeper	0.4	0.16	Field-hockey goalkeeper success should correlate moderately with soccer goalkeeper success. The role similarity is substantial at the functional level: both are dedicated shot-stoppers who must track fast attacks, read intentions early, maintain coverage geometry/angles, and react quickly under pressure. The correlation is not very high because the dominant technical center of gravity differs. Hockey goalkeeping uses stick/leg save mechanics and turf/goal-area positioning constraints; soccer goalkeeper performance is driven heavily by soccer-specific diving/handling/footwork, plus different ball dynamics (including bounces, aerial balls) and distribution responsibilities. Net: a moderate positive correlation (around 0.40) with meaningful individual variation driven by how well perceptual/positioning skill generalizes versus how quickly athletes learn soccer-specific save and handling mechanics.	[154] [155] [156] [157]
field-hockey-outfield	0.35	0.18	Field-hockey outfield success should correlate moderately with soccer goalkeeper success, but not highly. Shared transferable elements are mainly perceptual-cognitive and behavioral: tracking a fast incoming ball/passing lane, anticipating attackers’ options, making quick decisions under pressure, and staying mentally organized in defense. However, soccer goalkeeper performance is highly specialized technically: hand catching/box handling, diving and safe landing mechanics, shot-angle/positioning patterns specific to soccer’s goal shape and ball trajectories, plus distribution skills and communication patterns. Hockey outfield roles do not train those core goalkeeper mechanics. Therefore the technique-transfer component is limited, leading to a moderate correlation centered around ~0.35 with substantial uncertainty (plausibly ~0.15–0.55).	[158] [159]
golf	0.08	0.06	Golf success should correlate modestly but not strongly with soccer goalkeeper success once body-size/trait effects are excluded. Transfer is mainly general: precision, technique discipline, and some visual tracking/timing. However, goalkeeper performance is dominated by soccer-specific reactive and whole-body motor patterns (diving/footwork, positioning, rebound control) within an opponent-driven, highly variable environment—skills golf does not meaningfully train. Therefore the correlation remains limited rather than high.	[160] [161] [162] [163] [164]
gymnastics-artistic	0.25	0.1	Artistic gymnastics should correlate positively with soccer goalkeeping because there is meaningful overlap in transferable technique components: balance recovery, controlled body positioning in mid-air, trunk/hip bracing, and efficient re-positioning after dives. Those map directly to the physical “save + recover” patterns in goalkeeping. However, goalkeeper success is also highly dominated by soccer-specific determinants—glove/ball-handling technique, catching angles, footwork patterns specific to the penalty area, and reading shot trajectories and line/pace differences from real soccer balls. These are not trained directly in artistic gymnastics. Therefore the carryover should be moderately positive (higher than many cross-sport athletic pairs, but not near-similar-position levels).	[165] [166] [167]
gymnastics-rhythmic	0.13	0.09	Rhythmic gymnastics should correlate positively with soccer goalkeeper success through transferable prerequisites: excellent balance, proprioception, and whole-body coordination. Those help a goalkeeper maintain correct stance/angles, absorb perturbations, and recover position after dives. However, goalkeeper performance is dominated by soccer-specific perceptual-motor and rule-constrained skills: tracking the ball’s flight off different shot types, timing hand placement for saves, executing dive and landing mechanics that match soccer ball trajectory and constraints, plus distribution/footwork decisions. Because rhythmic gymnastics does not train those adversarial ball-flight stimulus-response loops directly, the correlation is expected to be modest rather than large. A plausible Bayesian mean is ~0.13 with std dev ~0.09.	[168] [169] [170] [171]
gymnastics-trampoline	0.1	0.08	Trampoline should have a small-to-modest positive correlation with soccer goalkeeper success. The transferable element is primarily general neuromotor skill: balance, proprioception, dynamic body control, and stable re-centering after fast movements and dives. However, goalkeeper performance is highly constrained by soccer-specific technique and perception-action skills: reading ball flight from the shooter, catching/handling mechanics in real game contexts, and goalkeeper footwork/distribution. Those are largely not trained by trampoline. Therefore the correlation should remain modest, around ~0.10, with substantial uncertainty.	[172] [173] [174] [175] [176]
handball-backcourt	0.28	0.14	There should be some positive correlation because both roles require strong perception-action under pressure: - Tracking a fast-moving ball and responding quickly. - Anticipating where shots/attacks will come from. - Maintaining concentration over repeated scoring threats. - Basic understanding of attacking patterns and defensive organization. But the correlation is capped by major technique mismatch: - Soccer goalkeeper success is dominated by goalkeeper-specific mechanics (set stance, dive/extension angles, rebound control, catching/boxing, timing off crosses/through balls). - Soccer goalkeeper footwork and positioning (including dealing with ground balls and aerial balls) are not trained by handball backcourt. - Handball backcourt is perimeter play (throwing/shooting and defensive sizing), where arm throwing mechanics and court/spacing rules matter differently than save mechanics. So a modest average correlation (~0.28) with fairly large variability (std dev ~0.14) is plausible.	[177]
handball-goalkeeper	0.8	0.14	Both are “goalkeeper” shot-stopping roles, so the transferable core is large: reading the attacker’s intentions early, tracking fast ball flight, making rapid decisions under intense pressure, maintaining correct spatial positioning/angles, and handling chaotic rebounds/changes of threat. Those learned goalkeeping behaviors should correlate strongly. The correlation is not near-perfect because key technical elements differ: handball depends more on catching/deflecting with the body and immediate re-play mechanics, while soccer goalkeeping relies more on diving technique, boxing/clearing, foot-based saves, aerial command on crosses, and different distribution skills. Still, the role overlap is strong enough to keep the expected correlation high.	[178] [179]
handball-pivot	0.25	0.1	Handball Pivot and soccer Goalkeeper share several transferable, technique-relevant components: (1) playing in and near the goal area, (2) rapid ball trajectory tracking and anticipation, (3) decision-making under high pressure and physical crowding, and (4) body positioning and balance to act quickly. However, goalkeeper performance in soccer is shaped strongly by sport-specific mechanics: how you set your stance and use footwork on a large goal, how you time dives/blocks with the different ball movement and angles, dealing with crosses/lofted balls, and handling/rebounding within soccer rules. Pivot play focuses more on offensive close-quarter battling and passing/shoot-prep mechanics rather than the exact goalkeeper save/coverage templates. Therefore the carryover should be noticeably above zero but not very high—consistent with a moderate correlation.	[180]
handball-wing	0.18	0.1	Handball wing and soccer goalkeeper share some technique-relevant foundations: rapid ball tracking, early shot/angle recognition (from knowing how shooters create openings), and composure/reactivity in high-tempo situations. That should produce a modest positive correlation. However, goalkeeper success is dominated by soccer-specific techniques: staying properly positioned on the line/within the box, diving/shot-stopping mechanics, catching vs boxing, and goalkeeper distribution/decision rules. Wing play’s core motor programs (throwing/shooting mechanics, offensive spacing/finishing) don’t directly train keeper saves and movement patterns. Also, the roles are oppositely oriented (offense vs specialized defense), reducing transfer. So the correlation should be noticeable but not large, with substantial variability by training quality and individual adaptability.	[181] [182] [183]
ice-hockey-defenseman	0.27	0.14	Ice hockey defenseman success should correlate with soccer goalkeeper success at a moderate level. The overlap comes mainly from role demands that share interceptive elements: reading the attacker’s intent, tracking the ball/shot threat quickly, and maintaining correct positioning relative to goal danger. That produces a meaningful positive relationship. However, goalkeeper mechanics are very sport-specific. Soccer requires distinct footwork, diving/landing technique, handling/catching under different ball bounces, and dealing with aerial deliveries and distribution patterns—skills that are not trained in hockey defense. Locomotion constraints (skates vs turf) and rule/equipment differences further reduce technique transfer. Therefore the expected correlation should be positive but not high: roughly in the 0.25–0.30 range with substantial uncertainty.	[184] [185] [186] [187]
ice-hockey-forward	0.18	0.08	Ice-hockey forwards and soccer goalkeepers overlap mainly in perceptual/anticipation skills: reading the shooter’s intent, tracking the incoming puck/ball, and reacting quickly. That creates a modest positive correlation. However, goalkeeper technique is highly sport-specific. Soccer goalkeeping depends on specialized positioning within the penalty area, dive/jump mechanics and angles, catching/claiming/boxing technique, and distribution/command behaviors, none of which are central to hockey forward play. Because the dominant motor programs differ substantially, the carryover should not be large.	[188] [189] [190]
ice-hockey-goalkeeper	0.6	0.15	Ice hockey goalkeeper success should correlate strongly with soccer goalkeeper success because both roles are dominated by the same core technical/decision cycle: track a fast ball-like object early, anticipate the attacker’s intent, choose correct positioning/angles, react rapidly to unpredictable shots, and maintain composure after sudden events. The correlation is not expected to be extremely high (e.g., >0.85) because the sport-specific “save mechanics” differ a lot: ice uses a stick and puck on ice with different trajectories, while soccer saves rely on handling/shot-stopping with hands and/or feet, diving/footwork on turf, and different distribution of shot types and risk areas. Also, soccer has substantial penalty-area control behaviors tied to rules and ball behavior that hockey goalies do not train directly. Still, because you are matching goalkeeper-to-goalkeeper and the underlying perceptual-reactive and positioning fundamentals align well, a moderately-high mean correlation (around the low-to-mid 0.6 range) with meaningful spread is plausible. Spread remains large because some hockey goalies adapt quickly to soccer’s diving/handling/footwork, while others remain limited until they relearn those specific techniques.	[191]
judo	0.16	0.1	Judo and soccer goalkeeper overlap mainly in general, technique-relevant capacities: (1) staying balanced and recovering when perturbed, (2) rapid whole-body reorientation for reactive saves, and (3) safe landing/body-protection mechanics during sudden changes of direction and contact-like collisions. However, goalkeeper performance is dominated by soccer-specific determinants: reading the ball and opponent’s actions, tracking a rapidly moving ball, precise catching/handling, and keeper-specific footwork/positioning plus distribution/clearances within the Laws of the Game. Those are not meaningfully trained by judo. So past judo success should provide a noticeable but limited head start for goalkeeping learning and reactive movement quality, leading to a modest correlation (~0.15–0.2).	[192] [193]
lacrosse-attacker	0.13	0.12	Lacrosse attacker performance should show a modest positive association with soccer goalkeeper success mainly through transferable perceptual-motor abilities: tracking the ball, anticipating play, and reacting under pressure. However, goalkeeper excellence is dominated by soccer-specific technique and constraints—dive timing, positioning, catching/handling, distribution, and penalty-area command—which lacrosse attacking doesn’t directly teach. Therefore the expected correlation is low-to-modest with substantial variance across individuals.	[194] [195] [196]
lacrosse-defender	0.28	0.15	Lacrosse defender performance should correlate positively—but only moderately—with soccer goalkeeper performance. Shared transferable skills include: (1) anticipating where attacks are developing, (2) tracking a fast-moving ball and reacting to shots, (3) positioning to deny the most dangerous angles, and (4) staying mentally composed amid physical pressure and chaotic play. However, goalkeeping is extremely technique-specific. Soccer goalkeeper success depends on: (a) soccer ball handling/catching and securing, (b) dive/landing mechanics and recovery footwork on grass/turf, (c) reading shot spin/trajectory created by a different kicking tool (foot + ball physics) versus lacrosse stick dynamics, and (d) distribution/starting plays and close-range command. Lacrosse defense trains disruption and coverage with a stick, not the core goalkeeper save/footwork mechanics. So the correlation should be meaningful but not high.	[197]
lacrosse-goalkeeper	0.66	0.13	The correlation should be fairly high because both roles are highly analogous: both are dedicated goalkeeper shot-stoppers who must anticipate, track fast-moving balls, and react under pressure while maintaining correct positioning to reduce scoring angles. However, it won’t be extremely high/near-perfect because the save mechanics and ball behaviors differ substantially (stick-based catching vs soccer hand/foot goalkeeping mechanics, plus different rules and ball trajectories). Those mismatches cap transfer, but functional overlap keeps the mean in the mid-to-high 0.6 range.	[198] [199] [200] [201]
lacrosse-midfielder	0.22	0.1	Midfielder success in lacrosse should correlate positively with soccer goalkeeper success because the transferable “core” includes ball tracking, rapid reaction, anticipation, and performing under chaotic, high-pressure attacks. However, soccer goalkeeper performance is highly constrained by goalkeeper-specific technique and constraints: exact diving/shot-block mechanics, catching and handling rules, positioning in the penalty area, and clearing/starting actions. Lacrosse midfield play does not directly train those goalie motor patterns. Given this, the relationship should be moderate-but-not-high: a noticeable advantage from perception/anticipation and reflex readiness, but with substantial variance due to how quickly an athlete learns soccer-keeper mechanics and calibrates to soccer ball dynamics.	[202] [203] [204] [205]
padel	0.08	0.06	Padel performance should correlate modestly with soccer goalkeeper performance because both involve rapid tracking of an incoming ball and quick, high-pressure reactions. However, goalkeeper success is strongly determined by soccer-specific motor skills: positioning/angle control in the penalty area, diving and footwork mechanics, catching vs parrying under flight and pace, handling crosses, and distribution (kicking/rolling) with soccer ball physics. Padel’s racket timing and angled wall rebound cues do not provide equivalent practice for these goalkeeper-specific patterns. As a result, carry-over should remain small with substantial individual variance (people with prior football goalkeeping or general catching/throwing experience may transfer better).	[206]
pickleball	0.08	0.06	Pickleball success should have a modest positive carry-over to soccer goalkeeper performance through transferable perceptual-motor skills: tracking, early reads, fast reactions, and lateral positioning/recovery. However, goalkeeper performance is strongly determined by soccer-specific save technique (diving/catching/footwork), dealing with soccer-ball trajectories, and angle control, none of which are trained directly by pickleball. Team tactical context and shot-quality variance further reduce predictive power. Therefore the expected correlation is low-to-modest, around ~0.08 with meaningful uncertainty.	[207] [208] [209] [210] [211]
rowing-lightweight	0.05	0.04	Lightweight rowing should have only a small positive correlation with soccer goalkeeper success. The transferable components are mostly general athletic/technical habits: body control, balance, and the ability to keep mechanics consistent while fatigued. However, goalkeeper performance is driven by soccer-specific determinants with limited rowing overlap: reading shots and tracking ball flight, explosively moving to precise positions, dive/catch/land technique, hand-eye timing for handling, and penalty-area control/distribution under pressure. Rowing does not meaningfully train the dive-and-catch reflex loop or the soccer-style repeated sprint/stop/reactive lateral movement patterns. So the expected carry-over is low (near ~0.05) with substantial variance depending on whether the athlete has parallel soccer experience or strong general reflex/ball-sport background.	[212]
rowing-openweight	0.05	0.04	Rowing openweight success is mainly driven by coordinated whole-body force application in a repeatable cyclic rhythm plus endurance/efficiency. Soccer goalkeeper success depends heavily on event-specific determinants: rapid visual tracking/anticipation, dive and save mechanics, catching/deflecting technique, penalty-area positioning and reading angles, plus specific quick-stop/lateral movement patterns. Those decisive goalkeeper technical skills have limited overlap with rowing, so direct technique transfer should be very small. The remaining transferable foundation is mainly general balance, whole-body coordination, and the ability to train and maintain quality under fatigue. Because those foundations are real but not dominant, the expected carry-over is low—near the lower end of small positive correlations.	[213] [214] [215]
rugby-union-halfback-midfield	0.2	0.2	Rugby union halfback/midfield performance should have a modest positive relationship with soccer goalkeeper success mainly through shared “read-and-react” components (anticipation, scanning, composure under pressure). However, goalkeeper performance is dominated by soccer-specific technique—handling/catching mechanics, diving and landing patterns, and penalty-area positioning with precise timing. Rugby halfback skills (distribution via passing/kicking and collision/phase play) provide only partial foundations. Because the technical and movement-mechanics mismatch is substantial and conversion to a specialized role is highly variable, the expected correlation is modest with a relatively large standard deviation.	[216] [217] [218] [219] [220]
rugby-union-loose-forward	0.13	0.08	A rugby loose forward can correlate modestly with soccer goalkeeper success because both roles involve high-pressure defense, quick reaction to danger, strong spatial awareness, and the ability to stay composed while fatigued and under physical challenge. However, goalkeeper performance is heavily determined by soccer-specific technical skills: catching/handling and ball control, diving and recovery mechanics, positioning/angle discipline in the penalty area, reading shots from the ball trajectory and shooter cues, and distribution (kicking/throwing) which follow soccer-specific rules. Rugby ruck/tackle/carrry contexts don’t train the core goalkeeper motor programs (shot-stopping dives, set-position footwork) or the exact soccer ball/trajectory interpretation. So the expected correlation is low-to-modest positive with substantial individual variance: some rugby athletes with naturally strong hand skills and reaction/coordination transfer better, while many will be limited by goalkeeper-specific technique learning.	[221]
rugby-union-outside-back	0.18	0.09	Rugby union outside-back success should have only a modest positive correlation with soccer goalkeeper success. The shared elements are reactive ball tracking, anticipation, and athletic lateral movement/recovery. However, goalkeeper performance is dominated by soccer-specific technique—diving/catching mechanics, positioning/angles in the penalty area, and keeper distribution/footwork—none of which are trained in the outside-back role. Therefore transfer is limited and correlation stays low-to-modest.	[222] [223] [224] [225] [226] [227]
rugby-union-tight-five	0.24	0.12	Rugby tight-five and soccer goalkeeper share some transferable, non-proportion components: both demand staying composed under repeated physical stress, role discipline within structured defenses, and quick decision-making when the game becomes chaotic. However, goalkeeper success is dominated by sport-specific technique: elite shot-stopping mechanics, catching/boxing/deflection skills, reading ball flight off the foot, and—critically—skating/footwork equivalents in soccer (dives, recoveries, positioning relative to the back line) tied to soccer timing and ball trajectories. Tight-five scrum/contact mechanics do not directly train those goalkeeper motor programs or the visual–motor loop of reacting to driven/curving shots. So the expected correlation is meaningfully positive but not high: enough for a noticeable head start in mental toughness/defensive organization and some general hand-eye advantages, but with substantial uncertainty due to the large technique gap. An average around ~0.24 with wide variance is plausible.	[228]
skiing-alpine-speed	0.12	0.11	Alpine speed-event skiing should have a modest positive relationship with soccer goalkeeping because strong skiers typically develop transferable athletic foundations: dynamic balance while moving fast, the ability to absorb/recover from large perturbations, and controlled low-to-high body positioning. But soccer goalkeeper success is dominated by highly sport-specific technique and timing: catching/claiming and shot-blocking mechanics (hands/legs and ball contact timing), plus distribution footwork with the ball. Skiing does not train these constraints directly. Additionally, the stimulus structure differs: skiing is continuous line control on a fixed run, whereas goalkeeping is discrete, opponent-driven shot-by-shot reactive behavior. That reduces the correlation. Balancing general movement transfer against large technique/timing mismatch yields an expected carry-over that is small but positive, around ~0.12 average correlation with substantial variability (~0.11 std dev) depending on whether the athlete also has prior soccer/ball experience and trains goalkeeper-specific skills early.	[229] [230] [231]
skiing-alpine-technical	0.08	0.07	Technical alpine skiing (slalom/giant slalom) can transfer modestly to soccer goalkeeper play via (1) balance and force absorption for maintaining stability during sudden perturbations, (2) rapid body reorientation and stance control, and (3) perceptual/decision skills like reading line/trajectory and committing at the right moment. However, the dominant goalkeeper requirements are highly soccer-specific: hand/arm technique for shot-stopping and catching, tracking the ball from specific release angles, diving/grounding mechanics tailored to the ball’s path on grass/indoor surfaces, and repeated ball-handling patterns under team play. Because these key motor programs are largely not trained by alpine skiing, the expected carry-over is small but positive.	[232]
skiing-cross-country	0.05	0.03	Skiing cross-country success correlates with aerobic capacity, movement economy, and whole-body coordination under fatigue—useful for a soccer goalkeeper’s ability to repeatedly sprint/reposition, stay balanced, and maintain technique across a match. However, a goalkeeper’s performance is heavily determined by soccer-specific technical/perceptual skills: reading shot trajectories and body shape, explosive first-step and dive mechanics on grass, precise catching/hand positioning, and distribution mechanics (kicking/throwing) plus decision-making tied to soccer patterns. XC skiing does not train these shot-stopping timing mechanics or the ball-specific handling skills. Therefore the carry-over should be near-zero but slightly positive due to general athleticism and conditioning. ~0.05 is plausible with low-to-moderate uncertainty.	[233]
snowboarding	0.1	0.13	Snowboarding and soccer goalkeeping share several general motor-learning prerequisites: dynamic balance, proprioception, and reacting to fast-moving stimuli. Those can make it slightly easier to learn basic goalkeeper movement organization and improve reaction timing. However, goalkeeper performance is dominated by soccer-specific shot-stopping technique: catching/boxing mechanics, dive timing and angles, footwork distribution, and repeatedly learning how the ball behaves off different turf conditions. Snowboarding provides limited direct practice of those repeatable techniques. So a low-to-modest positive carryover is expected: about ~0.10 average with moderate variability (~0.13), depending on additional goalkeeping/hand-eye experience outside snowboarding.	[234] [235] [236] [237]
soccer-central-defender	0.74	0.12	Central defender success should correlate strongly with goalkeeper success because both are soccer roles with major overlap in perceptual-cognitive demands: reading attacking patterns early, tracking ball/shot trajectories, reacting quickly, and staying organized under pressure. That creates a high positive carry-over. However, the technical architecture differs substantially. Central defenders are judged primarily on tackling, clearance/ball recovery, and aerial duel technique, while goalkeepers are judged on shot-stopping mechanics (hands/pads), diving and landing control, angle coverage, and goalkeeper-specific distribution/penalty-area control. This mismatch prevents the correlation from reaching the extremely high levels seen for very similar roles/positions within soccer.	[238] [239] [240] [241]
soccer-central-midfielder	0.5	0.18	Central midfielder and goalkeeper roles share meaningful cognitive soccer skills—reading the game early, anticipating opponents’ intentions, staying mentally sharp, and handling the ball under pressure. A CM who succeeds often has good scanning and decision-making, which can help a goalkeeper judge shots and organize the defensive line. However, goalkeeper performance is dominated by very specialized techniques: dive/cover mechanics, hand positioning, catching/parrying, and cue-based positioning relative to the penalty area. Those skills are not trained in the same way in central midfield. As a result the correlation is moderate rather than high. Overall, a mid-range positive correlation (~0.5) is plausible for technique/cognition transfer, even though the goalie-native skill set likely explains a large portion of the remaining variance.	[242]
soccer-striker	0.15	0.12	Striker and goalkeeper are both soccer positions, so they share some general technical and cognitive demands (ball tracking, timing, composure, understanding attacking patterns, and performing under pressure). That creates a modest positive relationship. However, the key technical bottlenecks diverge strongly: the goalkeeper’s success is dominated by shot-stopping technique (diving/catching/handling), positioning and angle coverage within the penalty area, communication/command of space, and laws-specific handling behavior. Striker success is dominated by finishing mechanics, creating chances through runs, and attacking decision-making. Because those role-specific technique components are largely non-overlapping, the correlation should be low-to-modest rather than high.	[243]
soccer-winger	0.35	0.18	Winger and goalkeeper are both soccer positions, so there is meaningful shared “soccer intelligence” and some transferable technical-tactical foundations (reading the game, timing of movements, using feet for distribution/clearances, and anticipating where danger will come from). That keeps the correlation clearly above zero. However, the goalkeeper’s success is heavily driven by goalkeeper-specific skills: safe ball handling, catching technique, diving/shot-stopping mechanics, positioning and angles in the penalty area, dealing with crosses at pace, and commanding the box—skills that a winger does not usually train as a core competency. This large technique gap prevents a high correlation. Therefore the expected average correlation is moderate, not high: around ~0.35, with substantial variance (higher for athletes with prior goalkeeping experience or who already mastered catching/1v1 defending; lower for typical wingers).	[244] [245] [246]
softball-catcher	0.4	0.18	Softball catcher success should correlate moderately with soccer goalkeeper success because both are primarily reactive shot-stoppers. Transferable components include reading where the ball is going early, staying in an effective low ready position, rapid first responses to incoming projectiles, and strong defensive organization/anticipation. However, soccer goalkeeping is not simply “catching with hands.” It relies heavily on soccer-specific technique and context: dive and fall mechanics, positioning relative to the goal/angles, handling/claiming and punching/box-outs, dealing with ground balls and different spin/trajectory, and controlling the penalty area and rebounds. Catcher training provides limited direct learning for these football-specific technical determinants. That mismatch prevents the correlation from being high.	[247]
softball-field-player	0.18	0.1	Softball field-player success should have a modest positive relationship with soccer goalkeeper success because both require strong perceptual-motor skills: tracking a fast ball, reacting quickly, and maintaining coordination while moving laterally. However, goalkeeper performance is specialized and soccer-specific: handling/catching technique for a kicked ball, dive and save mechanics, controlling the penalty area with reading of crosses/through balls, and accurate distribution (often with feet). Softball fielding trains catching/tracking, but not the core goalkeeper technique and rule constraints in soccer. Therefore the carryover should be low-to-modest rather than strong.	[248] [249] [250]
softball-pitcher	0.08	0.11	A softball pitcher transfers some useful skills to soccer goalkeeper play: (1) ball tracking and judging release/flight, (2) arm-hand coordination and power/accuracy in throwing-type actions, and (3) coping with high-pressure, repeated explosive efforts. However, the soccer goalkeeper’s dominant skill domains are different: rapid lateral/vertical footwork, set positioning, dive/landing mechanics, catching/box control under varying trajectories (often from crosses), and shot-reaction timing across many shot types, plus distribution decisions. Underhand pitching mechanics only partially resemble goalkeeper throws/distribution. Therefore the expected carry-over is small positive, not large.	[251]
squash	0.12	0.08	Squash and soccer goalkeeper overlap on general reaction/anticipation components: reading the ball’s path early, fast stimulus–response timing, and making coordinated, explosive movements in a limited space. However, goalkeeper success is dominated by soccer-specific technique and constraints: diving and landing mechanics on a pitch, correct body/arm angles for catching/ parrying, handling different shot types (driven shots, chips, crosses), dealing with bounce/skidding and ball physics specific to soccer, plus distribution skills (kicking/throwing) and position-specific tactical organization. Because squash does not train these sport-specific goalie motor patterns and decision rules, the carry-over should be positive but limited. A plausible Bayesian-centered estimate is therefore r ≈ 0.12 with std dev ≈ 0.08, reflecting modest transfer and meaningful individual differences (some squash players’ strengths will align more with reactive tracking; others will not).	[252]
surfing	0.08	0.06	Surfing should correlate weakly with success as a soccer goalkeeper (excluding body-size traits). Shared, technique-neutral elements include dynamic balance, quick re-centering after loss of equilibrium, coordination while moving, and staying composed while fatigued. But elite goalkeeper performance is dominated by soccer-specific technical/tactical skills: reading shot/ball trajectories from the box, proper diving mechanics and landing control, positioning/angles, handling and catching technique, dealing with through-balls and crosses, and the unique distribution/footwork patterns used by keepers. Surfing does not train the core perceptual-motor loop of shot-stopping in soccer or the specific diving/step/plant mechanics relative to a moving ball on grass. So the correlation stays low with wide individual variance depending on whether the athlete also has prior stick/ball catching, diving, or goalkeeper-specific training.	[253]
swimming-backstroke-middle-distance	0.08	0.06	Middle-distance backstroke success is mainly driven by rhythm, stroke economy, shoulder endurance, and maintaining efficient technique under fatigue. A soccer goalkeeper’s success depends more on sport-specific perceptual/technical skills: reading shooter cues, tracking ball trajectories, positioning in the box, and executing catching/diving/deflection mechanics safely and repeatedly. Because core goalkeeper mechanics and adversarial timing are largely different, direct skill transfer from backstroke should be limited. Only general athletic coordination, conditioning, and technique-learning discipline provide some advantage. Therefore a low positive correlation is plausible: ~0.08 average with uncertainty ~0.06, reflecting variability in whether the athlete also gains early ball-sport exposure before/while switching to soccer.	[254] [255] [256]
swimming-backstroke-sprint	0.04	0.03	Sprint backstroke success should correlate only weakly with soccer goalkeeper success. While there is some overlap in general athletic qualities—explosive quick-burst movement and executing technique under intense effort—the decisive goalkeeper skills are highly sport-specific: tracking and timing against unpredictable shot trajectories, catching/deflecting and rebound control, and goalkeeper-specific diving/stance footwork on turf. Sprint backstroke does not train these core perceptual-motor and landing/dive mechanics. Therefore the technique/skill transfer should be near-zero to very small positive, around ~0.04 on average.	[257] [258] [259] [260] [261]
swimming-breaststroke-middle-distance	0.1	0.06	Middle-distance breaststroke success is a decent signal of general coordination, rhythm/timing, and the ability to keep technique high-quality under fatigue—helpful for learning goalkeeper fundamentals (stance discipline, balance, repeatable movement quality, and training mindset). However, goalkeeper performance is strongly determined by sport-specific reactive skills: tracking a rapidly moving ball off a foot, positioning to reduce angles, reading shooter body cues, and executing correct dive/landing mechanics and rebound control. Breaststroke mechanics and cueing overlap only weakly with those demands, and the typical effort pattern differs (sustained output vs bursty saves). Net expectation: a low positive correlation with meaningful individual variation; it should not be a strong predictor of goalkeeper excellence.	[262] [263] [264] [265]
swimming-breaststroke-sprint	0.07	0.04	Sprint breaststroke success indicates strong whole-body timing (simultaneous arm–leg coordination), disciplined technique work, and ability to generate force quickly in short bursts (notably starts/turns/walls). These general qualities can help a goalkeeper with readiness, coordination, and explosive first steps. However, soccer goalkeeper success is dominated by highly sport-specific learned determinants: rapid visual tracking of a moving ball, split-second reaction timing to shots, diving/landing and save technique, and precise positioning/angle management. Swimming breaststroke does not train the core hand-eye and reactive save mechanics within the same interaction environment. Therefore the technique/skill carry-over is small positive rather than moderate.	[266] [267] [268]
swimming-butterfly-middle-distance	0.04	0.03	Swimming butterfly middle-distance success is primarily driven by water-specific propulsion/undulation coordination and maintaining efficient technique as fatigue accumulates. A soccer goalkeeper’s success relies much more on soccer-specific perceptual reads (shot/body/ball trajectory), positioning, and keeper save mechanics (dive/block/reaction timing). Because learned motor patterns and key perceptual cues overlap only weakly, direct technique-based carryover should be very small. A small positive association remains plausible from transferable general coordination, body control, and the ability to keep execution quality under repeated physical stress. Therefore the expected correlation is near the low end (~0.04) with moderate uncertainty.	[269] [270] [271] [272]
swimming-butterfly-sprint	0.05	0.04	Butterfly sprinting success suggests strong upper-body/whole-body coordination, explosive power bursts, and the ability to maintain technical mechanics under very intense short-duration fatigue. These general qualities can transfer a bit to a goalkeeper through improved body coordination, readiness for repeated high-intensity actions, and technical consistency under stress. However, soccer goalkeeper success is dominated by highly sport-specific techniques: reading shot trajectories and adjusting in time, correct positioning/centering in the box, dive mechanics relative to approach and contact angles, and catching/box distribution mechanics. Swimming butterfly does not meaningfully train these goalkeeper-specific perceptual-motor skills. Therefore, the expected technique-only correlation should be small and likely near the low end of positive transfer. A plausible Bayesian estimate is a mean around 0.05 with std dev around 0.04.	[273]
swimming-freestyle-distance	0.06	0.04	Swimming distance freestyle performance is mainly tied to endurance, efficiency, and maintaining coordination under fatigue. A soccer goalkeeper’s success (excluding body-trait effects like height/reach) is dominated by highly specific perceptual-motor skills: reading shots, diving/catching/blocking mechanics, and angle/positioning plus grass-footwork recovery. The overlap is therefore mostly indirect via conditioning, trainability, and general coordination. This yields a low but non-zero expected correlation around ~0.06 with moderate uncertainty.	[274] [275] [276]
swimming-freestyle-middle-distance	0.06	0.04	Middle-distance freestyle success is driven mainly by aerobic efficiency, pacing/effort regulation, and highly specific front-crawl propulsion/body alignment. Soccer goalkeeper success depends heavily on technical shot-stopping mechanics, precise positioning and dive timing, and reacting to sport-specific ball trajectories and shooter cues. Direct technical overlap between freestyle swimming and goalkeeper skills is minimal. Therefore swimming performance should only weakly predict goalkeeper performance. A small positive carry-over is expected from general coordination, balance, training discipline, and some limited perceptual-reactive similarity, yielding a low correlation close to baseline.	[277] [278] [279]
swimming-freestyle-sprint	0.05	0.05	Sprint freestyle success reflects explosive power expression (starts/turns) and high-rate movement coordination. Soccer goalkeeping also values rapid reactions and explosive movement bursts, creating a small positive carry-over. However, the decisive determinants for goalkeeper performance are highly sport- and role-specific: reading the ball from the shooter’s cues, positioning/angle control in the penalty area, and executing soccer goalkeeper dives and lateral recovery mechanics. Swimming sprinting does not train these goalkeeper-specific perceptual routines and movement patterns. Therefore the expected correlation is small, near the low end.	[280] [281] [282] [283] [284]
table-tennis	0.2	0.13	Table tennis success should have a modest positive correlation with future soccer goalkeeper success because both rely on rapid visual tracking, early anticipation, and precise, timely responses to fast shots. However, goalkeeper performance is dominated by soccer-specific mechanics (diving/catching/deflecting angles, penalty-area positioning, and footwork/stance under rules and flow of play) that only partially relate to racket-spin contact. Therefore the expected carry-over is meaningful but not strong: ~0.20 on average with moderate uncertainty (~0.13).	[285] [286] [287] [288]
taekwondo	0.16	0.05	Taekwondo success should correlate modestly with future soccer goalkeeper success due to transferable ingredients: fast reaction timing, explosive defensive repositioning, balance, and mental composure. However, goalkeeper performance is constrained by soccer-specific technique—save selection/positioning, diving and catching/boxing mechanics, and goalkeeper distribution/footwork with the ball—which taekwondo does not directly develop. Thus the carry-over is expected to be modest rather than large.	[289] [290] [291] [292] [293]
tennis	0.16	0.06	Tennis should correlate moderately with soccer goalkeeper success because both require early ball-reading, fast reactive movement, and strong body/footwork coordination to intercept a shot. However, goalkeeper performance in soccer is dominated by sport- and position-specific save mechanics (diving angles, catching/deflecting, shot-types from different distances), plus soccer-specific tactical context (penalty-area positioning, crosses/through balls, defensive organization). Tennis does not directly train those core determinants, so the carry-over should be meaningful but not high.	[294] [295] [296]
triathlon	0.06	0.03	Triathlon success should have only a weak relationship with soccer goalkeeper success. Goalkeeper determinants are highly sport- and role-specific: tracking a small ball from short distances, reacting quickly to shot type/body cue, maintaining correct positioning and angles, managing the penalty area, and executing precise catching/diving/clearance technique. Triathlon does not meaningfully train these ball-tracking and shot-stopping mechanics. The only overlap is generalized athletic ability and the ability to train consistently while fatigued, which may slightly help with learning speed and match fitness. Therefore the expected correlation remains small (~0.06) with modest variance.	[297]
volleyball-attacker	0.07	0.07	Volleyball attackers share a small set of reactive, technique-neutral abilities with soccer goalkeepers: tracking a moving ball quickly, coordinating body movements at the last second, and maintaining composure during high-pressure moments. But soccer goalkeeper success depends strongly on goalkeeper-specific motor skills: diving mechanics and recovery, positioning/angle control in a penalty area, judging and handling balls that bounce/roll differently on turf, and distribution/clearance techniques unique to soccer. Volleyball attacking does not meaningfully train those goalkeeper movement and ball-handling programs. Therefore the expected carry-over is small—around ~0.07—with noticeable individual variation depending on prior goalkeeper experience or general stickless ball goalkeeping exposure.	[298] [299]
volleyball-libero	0.22	0.12	Volleyball libero success should correlate positively with soccer goalkeeper success because both roles are strongly defensive and depend on (1) reading the opponent early and anticipating where the ball will go, (2) rapid movement to a “save position” and maintaining balance/stance, and (3) hand-eye/ball-tracking skill for controlling fast, incoming projectiles. However, goalkeeper performance is heavily shaped by sport- and technique-specific elements not trained in libero volleyball: diving/landing mechanics on a hard pitch, catching/boxing vs deflecting decisions, dealing with rolling and curving shots (different trajectories/spin), off-the-line footwork, and distribution/clearance habits. Libero digging and reception use different contact mechanics (forearm platform) and mostly occur over a net with different ball physics. So the carry-over is noticeable but limited: a plausible mid-low correlation is ~0.22, with substantial variation depending on how much the person also has soccer experience/keeper-specific practice.	[300]
volleyball-middle-blocker	0.07	0.08	Volleyball middle blockers train strong perceptual timing and ball-tracking, plus fast whole-body repositioning and coordinated upper-body actions at the moment the ball arrives (blocking/attacking). Those general skills can translate to soccer goalkeeping as improved “read the shot early and get positioned quickly” behavior. However, soccer goalkeeper performance is dominated by soccer-specific save technique: diving/catching/boxing mechanics, choosing the correct body angle, handling varying shot types (low drives, chips, driven shots, deflections), and goalkeeper distribution and penalty-area positioning under continuous running and contact with the ground-ball environment. Volleyball net blocking is not a direct substitute for goalkeeper diving and ball-handling on the ground/through the air. Therefore the carry-over is likely weak (small positive correlation).	[301] [302]
volleyball-setter	0.1	0.11	Volleyball setters and soccer goalkeepers overlap in a limited but real way: both can develop good early reading of where a fast ball will go and can respond quickly with body positioning. However, soccer goalkeeper performance is driven heavily by highly sport-specific technical learning: stance and glove/hand positioning, diving and rebound control on different surfaces, handling crosses/shot types governed by soccer rules, and goalkeeper footwork/line management. Volleyball setting’s overhead two-contact ball placement does not directly train these core shot-stopping mechanics. Because the overlap is mostly general anticipation/reactivity rather than the key goalkeeper techniques, the expected correlation is low but not zero. A realistic Bayesian estimate is ~0.10 with fairly high uncertainty (~0.11).	[303] [304] [305]
wrestling	0.14	0.12	Wrestling and soccer goalkeeper overlap mainly in general opponent-interaction abilities: maintaining balance under physical pressure, controlling body position in close contact, and staying mentally composed when things get chaotic. Those create a modest positive carry-over. But a goalkeeper’s success is strongly driven by soccer-specific perceptual-motor and technique skills: reading the shot, tracking the ball, reacting quickly, and executing correct dive/catch/landing mechanics and penalty-area positioning. Wrestling does not train these core goalkeeper tasks. Therefore the correlation should be low-to-moderate and fairly variable. Plausible average: ~0.14 with SD ~0.12.	[306] [307] [308]
