Athletes' bodies
Elite male taekwondo athletes are typically tall with long limbs (greater effective striking reach), lean enough to compete within weight categories, and have high lower-limb explosive power plus substantial flexibility for high kicks. Body-frame proportions (arm-span/height and leg-to-torso proportions) are generally optimized for producing fast, well-timed kicking distances while maintaining agility for footwork and evasion.

Measurements
| Factor | Prior | Posterior | Success-impact | Reasoning behind prior | Prior estimate sources |
|---|---|---|---|---|---|
| Ape index | 1.03 ± 0.03 ratio | 1.03 ± 0.03 ratio | high | Ape index slightly >1 supports longer reach for striking; set close to common athletic distributions with moderate spread. | [1] |
| Arm span | 188 ± 6.5 cm | 188 ± 6.5 cm | high | Taekwondo favors longer reach; for an average height ~182 cm, a typical male arm-span/height ratio near ~1.03–1.05 yields an arm span around ~188 cm with moderate elite spread. | [2] [3] [4] |
| Height | 182 ± 6 cm | 182 ± 6 cm | high | Using reported mean elite male taekwondo height around ~183 cm as a center point, with a realistic adult elite variability (~±6 cm) reflecting weight categories and body-size diversity. | [3] [5] |
| Leg-torso ratio | 1.66 ± 0.06 ratio | 1.66 ± 0.06 ratio | high | Computed/model-consistent with a tall athlete having a relatively long effective kicking lever relative to trunk length; variability kept small to reflect elite selection toward advantageous proportions. | [3] |
| Weight | 72.5 ± 8.5 kg | 72.5 ± 8.5 kg | high | Centered near published ~73 kg mean elite male weight and widened modestly to reflect adult elite athletes competing in different categories with typical lean mass preservation. | [2] [5] |
| Ankle circumference | 22.2 ± 1.4 cm | 22.2 ± 1.4 cm | medium | Proportional estimate consistent with lean elite males and moderate variability; ankle circumference correlates with distal limb robustness and potentially tolerance to repeated impact/kicking stabilization. | [6] |
| Foot length | 27.8 ± 1.3 cm | 27.8 ± 1.3 cm | medium | Estimated from typical adult male foot length for an athlete with ~182 cm height; foot length and geometry affect footwork stability and push-off mechanics. | [7] |
| Leg inseam | 86 ± 4.5 cm | 86 ± 4.5 cm | medium | Estimated from typical anthropometric proportions for adult males at ~182 cm height (in-seam scales with stature). Used as an approximate proxy for effective kick-leg lever length rather than as a directly sourced inseam mean for elite TKD. | [2] |
| Shoulder-hip ratio | 0.98 ± 0.05 ratio | 0.98 ± 0.05 ratio | medium | Modeled to be close to 1 (balanced proportions) because TKD emphasizes leg-driven striking rather than extreme shoulder-dominant strength/width. | [2] |
| Shoulder width | 44 ± 3 cm | 44 ± 3 cm | medium | Estimated from typical male frame geometry for an athlete around 180–185 cm; taekwondo does not require maximal shoulder breadth (unlike some grappling/pressing-dominant sports), so shoulder width is only a moderate differentiator. | [2] |
| Torso length | 60.5 ± 3.5 cm | 60.5 ± 3.5 cm | medium | Estimated from typical trunk-to-stature proportions; TKD benefits from the ability to keep balance and generate leg forces with minimal trunk restriction, so torso length is treated as moderately important. | [6] |
| Hand length | 19.2 ± 1 cm | 19.2 ± 1 cm | low | Modeled proportionally for a male around ~182 cm; hand length is low importance for kicking combat sport success (more related to guarding/timing than strike reach). | [2] |
| Pelvic bone width | 28 ± 2.2 cm | 28 ± 2.2 cm | low | Proportional estimate for a lean, tall male athlete; used mainly to support torso/leg proportional indices rather than as a key TKD discriminator. | [6] |
| Wrist circumference | 16.6 ± 1.1 cm | 16.6 ± 1.1 cm | low | Estimated based on typical adult male wrist girth for a lean elite athlete around ~180–185 cm; primarily reflects general frame size. | [6] |
Traits
| Factor | Value | Impact | Reasoning | Sources |
|---|---|---|---|---|
| Muscle fiber profile | fast-twitch dominant | high | Taekwondo scoring relies heavily on rapid, explosive kicking actions and repeated high-intensity bursts; this aligns with a fast-twitch dominant optimal profile (with some oxidative contribution for repeated exchanges). | [8] [9] |
| Metabolic tendency | ectomorphic tendency | medium | Modeled as ectomorph-leaning because elite male TKD athletes often manage leanness and present tall, relatively low-fat profiles to maintain speed and reach advantages within weight divisions. | [8] |
| Joint laxity | high | high | High joint laxity (or at least high achievable functional ROM supported by training) is valuable for chambering speed and executing high/side kicks safely and repeatedly. | [8] |
| Foot arch | neutral arch | medium | Neutral arch is chosen because TKD requires both stability during footwork and flexibility for varied stances; extremes of flat/high arch are less consistently advantageous than an adaptable neutral mechanics profile. | [10] |
| Temperature tolerance | balanced | low | No strong, sport-specific evidence that TKD elite performance systematically favors heat- or cold-tolerance extremes; kicking/sprints depend more on warm-up, ROM readiness, and anaerobic capacity. | [9] |
| Dominant side | no meaningful side advantage | low | While individual taekwondoists often have a preferred lead/side, the population-level elite advantage is not clearly directional enough to encode right vs left superiority, so it is set to neutral. | [9] |
Goals
| Factor | Alignment | Reasoning | Sources |
|---|---|---|---|
| Build confidence | medium | Taekwondo gives frequent feedback (technique progress, belt/rank milestones, sparring improvements). That can build confidence, especially for beginners. However, confidence is not guaranteed because sparring intensity or fear of contact can be a barrier for some people. | [11] [12] |
| Build endurance | medium | Taekwondo includes intermittent hard efforts (rounds, sparring) that can improve aerobic fitness, especially with frequent training. However, the sport also has lots of stop-start explosive work, so endurance gains tend to be moderate for amateurs unless the class is well-conditioned or you add extra cardio. | [13] [14] |
| Build strength and power | high | Although it’s a striking sport, taekwondo practice strongly trains lower-body strength and power (kicking, chambers, lunges, stance work) and also recruits core and upper body for balance and control of strikes. Beginners usually notice noticeable strength improvements within months. | [14] [15] |
| Challenge myself | high | For amateurs, taekwondo can feel demanding quickly: mastering form, maintaining balance through kicks, building conditioning, and learning to control power/timing. Belt progression and sparring provide clear personal challenge and stretch. | [16] [17] |
| Compete and measure myself | medium | There are competitions for taekwondo (tournaments, sparring forms/poomsae events, belt-adjacent milestones). That gives a way to measure progress. But many amateurs compete rarely, so the alignment is moderate rather than “high” by default. | [14] |
| Improve agility and coordination | high | Footwork drills, stance transitions, partner sparring, and timing-based kicking all require coordinated movement under changing conditions. That makes taekwondo a strong fit for agility/coordination—especially for amateurs learning to connect timing, distance, and body control. | [14] [18] |
| Improve balance and control | high | Taekwondo relies on maintaining stable footing during kicks, recovering balance during re-chambers, and controlling posture through stance work. Even beginners get lots of practice balancing on one leg and managing center-of-mass shifts. | [18] [19] |
| Improve flexibility and mobility | medium | Taekwondo often includes stretching and kicking-related range-of-motion work, which can improve mobility over time. Still, many classes focus on technique and conditioning more than systematic mobility progression, so results vary a lot by gym and how much your training includes stretching. | [14] [20] |
| Improve general health and fitness | high | Taekwondo training typically includes repeated bouts of kicking drills, footwork, sparring, and conditioning. For amateurs, that usually adds up to regular full-body movement and meaningful cardiovascular + muscular training, which makes it a strong all-around choice for general health and fitness. | [14] [16] |
| Improve speed and explosiveness | high | Your description matches the sport’s core skill demands: fast kicks, timing, and explosive distance management. Training repeatedly practices rapid lower-body acceleration, strike execution, and quick re-chambering—so speed and explosiveness are typically among the most directly trained attributes. | [13] [14] |
| Learn new skills and master technique | high | Taekwondo is fundamentally a technique-learning sport: kicking mechanics, stance control, timing, and combinations. Progression is typically systematic (curriculum, belt requirements), so it’s very aligned with the goal of learning and mastering technique. | [14] |
| Lose weight | medium | Taekwondo can help with weight loss because it burns calories and can improve overall fitness—but outcomes depend heavily on total weekly training time and diet. As a standalone plan it’s often effective, but not as consistently predictable as structured cardio or a full nutrition + training program. | [11] [14] |
| Make friends and feel a sense of belonging | medium | Most taekwondo schools are structured and community-based, so it’s fairly common to meet people and build friendships—especially when sparring partners rotate and classes include group drills. That said, it depends strongly on the gym culture. | [16] |
| Reduce stress and feel better | high | Martial arts training can improve mood and psychological wellbeing, likely via a mix of physical exertion, structured practice, focus, and social support. Evidence specifically involving taekwondo and broader martial arts programs points toward meaningful mental health benefits for many people. | [11] [16] [21] |
| Spend time with people I care about | low | Taekwondo is often practiced with partners/coaches, but it’s not usually the kind of activity where you can easily talk and catch up while training (interval intensity and safety cues). You might do this more with friends outside class (arriving early, watching, or traveling), but during practice it’s usually not ideal. | [22] |
Preferences
| Factor | Alignment | Reasoning | Sources |
|---|---|---|---|
| Competition-focused environment | medium | Taekwondo has a strong competition pathway (sparring rules, scoring, belt gradings). But amateur community dojos also emphasize fitness/skill learning, so it’s not always a “results-only” culture. | [23] [24] |
| Enjoys contact | medium | Contact happens in the sense of kicking/punching an opponent (often with protective gear and controlled force at amateur level). Still, it’s not generally grappling-heavy or collision-heavy like some other combat sports. | [25] [26] |
| Flexible Time Table | medium | You can practice forms and drills on your own and at different times (flexible). But full sparring usually requires a class schedule or a partner, which limits flexibility somewhat. | [27] |
| Indoor setting | high | Most taekwondo clubs train in dojangs (gyms/indoor training spaces), where sparring and drills are done in controlled conditions. | [25] |
| Long steady efforts | low | Taekwondo bouts are usually composed of bursts of action separated by pauses/counterplay. You do build fitness, but it’s not primarily about long, steady pacing like distance running or cycling. | [25] |
| Low impact on joints | low | Taekwondo involves frequent high-speed kicks and repetitive lower-body loading. Studies and injury data commonly show lower-limb injury patterns, so it’s not typically “easy on joints.” | [28] [29] |
| Mostly individual | high | Most of the practice is about your own technique, fitness, forms (patterns/poomsae), and rounds against an opponent. Even sparring is not team-based—your performance is largely independent. | [25] [30] |
| Non-contact | low | While you can train with reduced-force or point-sparring, taekwondo’s defining element is striking with contact at the technique level during drills/sparring; it’s not primarily “no-contact.” | [31] |
| Outdoor setting | none | There isn’t a typical taekwondo practice format that regularly happens outdoors; the standard environment is a dojang/gym. | — |
| Playful recreational atmosphere | low | Taekwondo can be fun, but the standard atmosphere is typically disciplined and training-oriented, with sparring that can feel serious even if done safely. | — |
| Routine and structure | high | Training is typically very structured: belt progression, repeatable drills, and forms (poomsae), plus scheduled sparring rounds. It’s easy to practice in a consistent progression format. | [25] [32] |
| Short explosive efforts | high | The sport is built around fast, explosive kicking bursts—speed, timing, and generating force across short attack windows are central. | [25] [33] |
| Tactical and strategic | medium | Even though it’s striking-focused, you still need to read distance, feints, timing windows, and choose tactics (where to attack, how to manage the exchange). But it’s less “plan-and-execute” like chess/strategy sports and more reactive. | [34] |
| Team environment | low | Taekwondo is usually practiced around one-on-one training partners and individual skill development (even when classes are group-based). Team tactics aren’t the core of how you win or train. | [25] |
| Technique-heavy | high | Precision (distance control, kicking mechanics, timing, and clean execution) is the whole point. Progress is usually measured by form quality and how well you execute techniques. | [25] [35] |
| Variety and novelty | medium | There’s variety through different kicks, combinations, and poomsae, plus changing opponents in sparring. However, much training can become repetitive while you master fundamentals. | [36] |
| Water environment | none | Taekwondo is not normally practiced in a water-based setting. | — |
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. | Direct epidemiology specifically naming Achilles tendinopathy as a frequent taekwondo diagnosis is limited, but taekwondo’s high lower-limb exposure and recorded foot/ankle injury burden (including ankle/foot issues) makes Achilles tendon overuse a plausible risk. Because the sport strongly loads the calf–Achilles complex, risk is set to medium rather than none. | [37] [38] |
| ACL injury | low | A major ligament injury inside the knee, often linked to pivoting, landing, or sudden deceleration. | Taekwondo has high lower-limb exposure, and ACL injury risk can be plausible given dynamic single-leg landings. However, the taekwondo injury distribution studies retrieved emphasize foot/ankle and knee injuries generally, and do not strongly single out ACL as a top incidence diagnosis. With that uncertainty and no strong taekwondo-specific ACL-specific incidence data in the sources pulled, risk is set to low rather than medium/high. | [39] [40] |
| Ankle sprain | high | A stretched or torn ankle ligament, usually after the foot rolls awkwardly. | Multiple taekwondo injury analyses report foot and ankle injuries as common sites. A dedicated 4-year elite-athlete analysis shows a high prevalence of recorded foot/ankle injuries across athletes, supporting high injury likelihood for ankle-region problems. Given the sport’s repeated landing and kicking demands, ankle sprain risk is graded high. | [38] [42] [43] |
| Calf strain | medium | A pulled or overloaded calf muscle, often felt during pushing off, sprinting, or jumping. | Direct calf-strain incidence is not isolated in the retrieved taekwondo injury sources, but the high foot/ankle injury burden and the sport’s explosive lower-limb mechanics support a medium risk for calf strains. | [37] [38] |
| Finger or hand impact injury | low | Pain from jamming, bending, or striking the fingers or hand during sport. | The taekwondo injury distributions highlight lower extremity frequency. Hand/finger impact injuries are plausible but not the main documented pattern in the cited sources; therefore low risk. | [46] [47] |
| General forearm overuse pain | none | Ongoing forearm pain from repeated gripping, lifting, or arm use when the exact tendon is unclear. | Most taekwondo injury surveillance focuses on the lower extremity (especially foot/ankle and knee) and includes bruises/soft-tissue injuries from kicking and contact. Forearm overuse pain is not highlighted as a common injury location for taekwondo participation in the cited injury-distribution studies, so the risk from taekwondo practice is treated as none. | [42] [48] |
| General foot or ankle pain | high | Ongoing foot or ankle pain when the exact structure or diagnosis is unclear. | The elite-athlete 4-year descriptive study reports substantial foot/ankle injury prevalence (nearly half of athletes experiencing foot/ankle injuries during the period). Broader injury analyses also identify foot and ankle among the most frequent sites. Since “general foot/ankle pain” is a broader bucket than specific sprain/diagnosis, risk is high. | [38] [39] [42] |
| General hip or groin pain | medium | Ongoing hip or groin pain when the exact structure or diagnosis is unclear. | Systematic reviews show lower-limb injury predominance, and taekwondo’s kicking mechanics strongly stress hip flexors/adductors. While the cited sources mostly emphasize foot/ankle/knee, hip/groin pain is a biomechanically credible risk and appears in taekwondo back/waist/lower-limb surveillance generally. Hence medium rather than low. | [39] [49] |
| General knee pain | high | Ongoing knee pain when the exact structure or diagnosis is unclear. | Injury analyses of taekwondo report knee as one of the most frequently injured body regions, and systematic reviews describe lower-limb injury predominance. Because “general knee pain” includes both acute and overuse presentations, risk is high. | [39] [42] [50] |
| General lower-back pain | low | Ongoing lower-back pain when the exact source is unclear. | Some injury surveillance in youth/collegiate taekwondo shows lumbar/lower-back involvement, but systematic reviews still emphasize lower-limb injury predominance. Therefore risk is low rather than medium/high. | [39] [51] |
| General lower-leg pain | high | Ongoing shin or calf pain when the exact diagnosis is unclear. | Taekwondo injury surveillance shows foot/ankle and knee injuries dominate. “General lower-leg pain” includes shin/calf/ankle complex; given that posterior and distal lower-limb problems are common, risk is high. | [42] [54] |
| General shoulder pain | low | Ongoing shoulder pain when the exact structure or diagnosis is unclear. | Injury distribution studies show foot/ankle and knee as dominant sites. Shoulder injuries are reported but not usually as the most frequent. So overall shoulder pain risk is low. | [39] [42] |
| General wrist or hand pain | none | Ongoing wrist or hand pain when the exact structure or diagnosis is unclear. | No evidence in retrieved taekwondo injury-distribution sources indicates wrist/hand pain is common. So risk none. | [47] |
| Golfer's elbow | none | Pain on the inside of the elbow linked to overload in the forearm tendons. | Common taekwondo injuries are mostly lower-limb/foot/ankle/knee and contact/bruising, not wrist/forearm flexor overuse. With no evidence presented in the cited taekwondo injury-distribution sources that golfer’s elbow is common, risk is none. | [42] |
| Groin strain | medium | A pulled or irritated groin muscle, often felt in cutting, sprinting, or kicking movements. | The injury literature for taekwondo highlights lower-limb regions and common sprains/muscle injuries, but the specific groin-strain diagnosis frequency is not isolated in the sources retrieved. Still, biomechanics and the overall lower-extremity injury burden support a medium risk for groin strains. | [39] [55] |
| Hip flexor strain | medium | A strain or overload in the front-of-hip muscles that help lift the leg. | Taekwondo’s kicking mechanics create high hip-flexor workload. While the cited injury-site studies mainly quantify foot/knee/ankle distributions, the sport’s known lower-limb injury burden supports medium risk for hip flexor strain. | [39] [50] |
| Side-of-hip tendon pain | low | Irritation of the hip or gluteal tendons around the outer side of the hip. | The retrieved taekwondo injury distributions emphasize foot/ankle and knee more than hip/glute tendinopathy diagnoses. That said, repetitive kicking and high stance demands can plausibly irritate hip tendons, so risk is low (not none). | [39] [42] |
| Lower-back disc irritation | none | Lower-back pain that may involve irritation of a spinal disc and sometimes pain spreading into the leg. | While taekwondo involves twisting/impact and can cause back pain, the specific category “lumbar disc irritation” is not directly supported as common in the taekwondo injury epidemiology sources pulled. With no direct evidence, risk defaults to none. | [39] [56] |
| Mechanical lower-back pain | low | Common lower-back pain related to movement, loading, stiffness, or irritated supporting tissues. | Taekwondo injury epidemiology indicates some lumbar involvement, while lower-limb injuries predominate. Mechanical back pain is therefore plausible but not the primary expectation → low risk. | [39] [56] |
| Meniscus injury | low | Irritation or tearing of the knee cartilage that helps cushion and stabilize the joint. | The taekwondo injury sources retrieved quantify common body regions but do not provide strong meniscus-specific incidence. Therefore, risk is set to low to avoid overstating meniscus injury likelihood. | [39] [42] |
| Jumper's knee (patellar tendinopathy) | low | Pain and irritation in the tendon just below the kneecap. | Given plausible mechanics (knee extension during kicks) but lack of strong taekwondo-specific patellar tendinopathy incidence evidence, risk is low. | [39] [42] |
| Front-of-knee pain (patellofemoral pain) | low | Pain around or behind the kneecap that often flares with repetitive knee bending. | Because knee is common, patellofemoral pain is plausible; however, the cited taekwondo sources I pulled emphasize foot/ankle and knee generally, without patellofemoral pain specificity. Thus risk is low. | [42] |
| Heel pain (plantar fasciitis) | medium | Irritation of the tissue under the foot that often causes pain near the heel. | There is not strong taekwondo-specific epidemiology for plantar fasciitis as a named diagnosis in the sources I pulled, but plantar fasciitis risk is generally related to repetitive loading and foot mechanics—both heavily taxed in taekwondo. With common foot/ankle injury burden in taekwondo, the risk is treated as medium. | [38] [57] |
| Rotator cuff irritation | low | Pain and overload in the shoulder muscles and tendons that help control arm movement. | The taekwondo injury epidemiology sources retrieved emphasize lower-limb injuries as predominant. Upper-body rotator cuff irritation appears not to be a top site, so risk is low. | [42] [46] |
| Shin splints | medium | Exercise-related pain along the shin that often appears when impact load rises too quickly. | Direct taekwondo shin-splints incidence numbers weren’t retrieved in the sources above, but taekwondo’s high lower-limb loading and common foot/ankle/lower-leg injuries make shin splints a plausible medium-risk overuse condition. | [42] [54] |
| Shoulder impingement-type pain | none | Shoulder pain that appears when tissues feel pinched or irritated during arm elevation. | No taekwondo-specific evidence that impingement syndrome is common enough to rate above none. Therefore risk none. | [47] |
| Shoulder instability or dislocation | none | A shoulder that has slipped out, partly slipped out, or feels unreliable in vulnerable positions. | Given lack of evidence in the retrieved taekwondo injury surveillance that shoulder instability/dislocation is common, risk is none. | [47] |
| Back stress reaction (spondylolysis) | none | A stress injury in the back often linked to repeated extension and rotation loading. | Given lack of taekwondo-specific prevalence/incidence data for spondylolysis in the retrieved sources, risk defaults to none. | [39] [56] |
| Tennis elbow | none | Pain on the outside of the elbow linked to overload in the wrist and forearm tendons. | The injury-location evidence base for taekwondo points mainly toward lower-limb injuries rather than extensor-tendon elbow problems. Therefore tennis elbow risk is set to none. | [42] |
| Shin bone stress injury | low | Stress irritation in the tibia from repeated impact that has outpaced recovery. | Tibial stress injuries are plausible in any jumping/impact sport, but the retrieved taekwondo injury sources emphasize other sites. Without direct taekwondo tibial stress incidence evidence, risk is low. | [39] |
| Wrist sprain | none | A stretched or irritated wrist ligament, often after a fall, impact, or awkward bend. | Because the retrieved injury surveillance emphasizes lower extremity and doesn’t highlight wrist sprains as common, risk defaults to none. | [47] |
| Wrist tendon pain | none | Irritation of wrist tendons from repeated gripping, racquet use, lifting, or supporting body weight. | No evidence in retrieved taekwondo injury-distribution sources suggests wrist tendinopathy is common. Therefore risk none. | [47] |
Prevention
| Factor | Value | Definition | Full reasoning | Sources |
|---|---|---|---|---|
| Achilles tendon pain (tendinopathy) | low | Pain and irritation in the Achilles tendon at the back of the ankle. | Taekwondo training can improve lower-limb strength and neuromuscular control, which may help tissues tolerate load, but taekwondo also exposes you to high-impact kicking/jumping. With mixed direction evidence and no direct tendinopathy-prevention trial evidence, prevention is low rather than medium/high. | [38] |
| ACL injury | none | A major ligament injury inside the knee, often linked to pivoting, landing, or sudden deceleration. | No taekwondo-specific ACL prevention evidence was retrieved here. Without evidence that taekwondo itself (as practiced) reliably reduces ACL risk, prevention remains none. | [39] |
| Ankle sprain | low | A stretched or torn ankle ligament, usually after the foot rolls awkwardly. | Taekwondo includes balance/strength demands that may improve ankle stability, but there is no strong evidence in the cited sources that taekwondo participation alone reliably prevents ankle sprains (and ankle injuries are common). Therefore prevention is low rather than medium/high. | [38] [39] |
| Calf strain | low | A pulled or overloaded calf muscle, often felt during pushing off, sprinting, or jumping. | No direct calf-strain prevention trials for taekwondo. Still, general lower-leg strength from training could provide some protection. Therefore low. | [45] |
| Finger or hand impact injury | none | Pain from jamming, bending, or striking the fingers or hand during sport. | Because there is no direct prevention evidence, set to none. | [47] |
| General forearm overuse pain | none | Ongoing forearm pain from repeated gripping, lifting, or arm use when the exact tendon is unclear. | Given the lack of evidence that taekwondo regular practice specifically protects against forearm overuse conditions (and that taekwondo loading is dominated by kicking/leg work), the prevention effect is set to none by default. | [42] |
| General foot or ankle pain | low | Ongoing foot or ankle pain when the exact structure or diagnosis is unclear. | Evidence shows foot/ankle problems are common, so participation alone is unlikely to provide a strong preventive effect. However, conditioning and technique practice may offer some small protection, hence low prevention. | [44] |
| General hip or groin pain | low | Ongoing hip or groin pain when the exact structure or diagnosis is unclear. | Given the lack of taekwondo-specific evidence proving hip/groin pain prevention, and considering the sport’s repetitive hip loading, prevention is graded low. | [39] |
| General knee pain | low | Ongoing knee pain when the exact structure or diagnosis is unclear. | Without evidence of knee-pain prevention specific to taekwondo and considering knee injuries are common, prevention is low. | [39] |
| General lower-back pain | none | Ongoing lower-back pain when the exact source is unclear. | No taekwondo-specific back-pain prevention evidence is cited here, and since back injuries are not dominant but still present, prevention remains none. | [52] |
| General lower-leg pain | low | Ongoing shin or calf pain when the exact diagnosis is unclear. | Lower-leg issues are common, so taekwondo participation alone cannot be rated as strongly preventive. However, some conditioning benefit exists → low prevention. | [45] |
| General shoulder pain | none | Ongoing shoulder pain when the exact structure or diagnosis is unclear. | No taekwondo shoulder-pain prevention evidence is provided. Set prevention none. | [47] |
| General wrist or hand pain | none | Ongoing wrist or hand pain when the exact structure or diagnosis is unclear. | Default none. | [39] |
| Golfer's elbow | none | Pain on the inside of the elbow linked to overload in the forearm tendons. | Because taekwondo does not primarily target the wrist flexor tendon loading patterns associated with golfer’s elbow prevention (and taekwondo-specific evidence for this is not shown), prevention is none. | [42] |
| Groin strain | low | A pulled or irritated groin muscle, often felt in cutting, sprinting, or kicking movements. | No direct taekwondo prevention trials for groin strains were found in the retrieved sources, so prevention can’t be rated high. Strengthening/technique from training may help somewhat → low. | [39] |
| Hip flexor strain | low | A strain or overload in the front-of-hip muscles that help lift the leg. | Without specific evidence that taekwondo prevents hip flexor strains, prevention is low rather than medium/high. Conditioning benefits exist but are coupled with continuing high-demand hip flexion. | [39] |
| Side-of-hip tendon pain | low | Irritation of the hip or gluteal tendons around the outer side of the hip. | No direct prevention trials for glute/hip tendinopathy in taekwondo, but the sport can improve general hip strength and control. With no strong evidence, prevention is low. | [39] |
| Lower-back disc irritation | none | Lower-back pain that may involve irritation of a spinal disc and sometimes pain spreading into the leg. | Without taekwondo-specific prevention evidence for disc irritation, set to none. | [52] |
| Mechanical lower-back pain | none | Common lower-back pain related to movement, loading, stiffness, or irritated supporting tissues. | No specific prevention evidence is provided here; therefore prevention stays none. | [52] |
| Meniscus injury | none | Irritation or tearing of the knee cartilage that helps cushion and stabilize the joint. | No taekwondo-specific meniscus prevention evidence. Set prevention none. | [39] |
| Jumper's knee (patellar tendinopathy) | none | Pain and irritation in the tendon just below the kneecap. | Without direct evidence, prevention is none. Taekwondo could both load and potentially help tissue capacity, but without data to support net prevention, keep none. | [39] |
| Front-of-knee pain (patellofemoral pain) | none | Pain around or behind the kneecap that often flares with repetitive knee bending. | Defaulting to none due to missing taekwondo-specific prevention evidence and mixed loading nature of the sport. | [39] |
| Heel pain (plantar fasciitis) | low | Irritation of the tissue under the foot that often causes pain near the heel. | Without taekwondo-specific prevention trials, prevention can’t be rated high. Conditioning might help, but the sport’s repetitive impact means net preventive effect from just “doing taekwondo” is likely modest, so low. | [45] [57] |
| Rotator cuff irritation | none | Pain and overload in the shoulder muscles and tendons that help control arm movement. | Without direct evidence, prevention remains none. | [39] |
| Shin splints | low | Exercise-related pain along the shin that often appears when impact load rises too quickly. | No taekwondo-specific shin-splints prevention evidence is cited; with likely bidirectional effects (conditioning vs repetitive impact), prevention is low. | [45] |
| Shoulder impingement-type pain | none | Shoulder pain that appears when tissues feel pinched or irritated during arm elevation. | Default none due to no direct evidence. | [39] |
| Shoulder instability or dislocation | none | A shoulder that has slipped out, partly slipped out, or feels unreliable in vulnerable positions. | Set none due to lack of evidence. | [39] |
| Back stress reaction (spondylolysis) | none | A stress injury in the back often linked to repeated extension and rotation loading. | Without specific prevention evidence, prevention remains none. | [39] |
| Tennis elbow | none | Pain on the outside of the elbow linked to overload in the wrist and forearm tendons. | No taekwondo-specific prevention evidence supports reduced risk of tennis elbow from regular participation. Defaulting to none. | [59] |
| Shin bone stress injury | none | Stress irritation in the tibia from repeated impact that has outpaced recovery. | No taekwondo-specific prevention evidence was retrieved. As a result, prevention is none. | [39] [52] |
| Wrist sprain | none | A stretched or irritated wrist ligament, often after a fall, impact, or awkward bend. | Default none. | [39] |
| Wrist tendon pain | none | Irritation of wrist tendons from repeated gripping, racquet use, lifting, or supporting body weight. | Default none. | [39] |

| Achilles tendon pain (tendinopathy) | low | Pain and irritation in the Achilles tendon at the back of the ankle. | Because healing of Achilles tendinopathy is usually improved by appropriate tendon loading, taekwondo could contribute some beneficial loading; however, taekwondo also tends to provoke high tendon stress via kicks/jumps, so net healing benefit for “regular taekwondo” is only modest. Set to low, not medium/high. | [38] |
| ACL injury | none | A major ligament injury inside the knee, often linked to pivoting, landing, or sudden deceleration. | No evidence supports that routine taekwondo practice improves ACL healing. Given the need for rehab and possible surgical management, heal is none. | [41] |
| Ankle sprain | none | A stretched or torn ankle ligament, usually after the foot rolls awkwardly. | With no direct evidence that routine taekwondo accelerates healing of ankle sprains (and given likely risk of aggravation during ongoing symptoms), healing benefit is set to none. | [44] |
| Calf strain | none | A pulled or overloaded calf muscle, often felt during pushing off, sprinting, or jumping. | No evidence that routine taekwondo practice heals calf strains. With likely pain-provocation, heal is none. | [45] |
| Finger or hand impact injury | none | Pain from jamming, bending, or striking the fingers or hand during sport. | No evidence that regular taekwondo helps heal hand/finger impact injuries. Heal none. | [47] |
| General forearm overuse pain | none | Ongoing forearm pain from repeated gripping, lifting, or arm use when the exact tendon is unclear. | No evidence indicates that continuing taekwondo would improve healing of forearm overuse pain (the common training stimulus is not specific rehabilitation for that tissue). Therefore heal is none. | [46] |
| General foot or ankle pain | none | Ongoing foot or ankle pain when the exact structure or diagnosis is unclear. | No cited evidence supports that regular taekwondo practice accelerates healing of nonspecific foot/ankle pain. Given the high re-stress risk, heal is none by default. | [44] |
| General hip or groin pain | none | Ongoing hip or groin pain when the exact structure or diagnosis is unclear. | No direct evidence supports that regular taekwondo participation improves healing of hip/groin pain. With potential for re-irritation from kicking patterns, heal is none. | [39] |
| General knee pain | none | Ongoing knee pain when the exact structure or diagnosis is unclear. | No evidence indicates taekwondo practice accelerates healing of nonspecific knee pain. Given repeated knee loading during kicks/landings, heal is none. | [47] |
| General lower-back pain | none | Ongoing lower-back pain when the exact source is unclear. | No evidence indicates that regular taekwondo practice (without specific rehab additions) reliably improves lower-back pain healing. Therefore heal is none. | [53] |
| General lower-leg pain | none | Ongoing shin or calf pain when the exact diagnosis is unclear. | No evidence supports that routine taekwondo practice heals general lower-leg pain. Because taekwondo continues to load the region, heal is none. | [45] |
| General shoulder pain | none | Ongoing shoulder pain when the exact structure or diagnosis is unclear. | No evidence supports healing benefit. Heal none. | [47] |
| General wrist or hand pain | none | Ongoing wrist or hand pain when the exact structure or diagnosis is unclear. | No evidence supports healing benefit from taekwondo practice. Heal none. | [39] |
| Golfer's elbow | none | Pain on the inside of the elbow linked to overload in the forearm tendons. | With no direct evidence that taekwondo practice improves healing of golfer’s elbow, and given the rehab focus typically requires targeted tendon-loading protocols, heal is none. | [42] |
| Groin strain | none | A pulled or irritated groin muscle, often felt in cutting, sprinting, or kicking movements. | No evidence supports that normal taekwondo practice speeds groin-strain healing; and kicking is likely provocative. Therefore heal is none. | [39] |
| Hip flexor strain | none | A strain or overload in the front-of-hip muscles that help lift the leg. | No evidence indicates that regular taekwondo accelerates hip flexor strain healing. Given likely pain-provoking activity, heal is none. | [39] |
| Side-of-hip tendon pain | none | Irritation of the hip or gluteal tendons around the outer side of the hip. | No evidence indicates that regular taekwondo practice heals hip/glute tendinopathy. Because the sport involves repeated hip loading, heal is none. | [39] |
| Lower-back disc irritation | none | Lower-back pain that may involve irritation of a spinal disc and sometimes pain spreading into the leg. | No evidence indicates taekwondo alone improves healing for lumbar disc irritation. Therefore heal is none. | [53] |
| Mechanical lower-back pain | none | Common lower-back pain related to movement, loading, stiffness, or irritated supporting tissues. | No evidence supports healing benefit from regular taekwondo practice for mechanical low-back pain. Heal is none. | [53] |
| Meniscus injury | none | Irritation or tearing of the knee cartilage that helps cushion and stabilize the joint. | No evidence supports that routine taekwondo practice improves meniscus healing. Heal is none. | [39] |
| Jumper's knee (patellar tendinopathy) | none | Pain and irritation in the tendon just below the kneecap. | No evidence supports that routine taekwondo accelerates patellar tendon healing. Heal is none. | [39] |
| Front-of-knee pain (patellofemoral pain) | none | Pain around or behind the kneecap that often flares with repetitive knee bending. | No evidence supports healing benefit from routine taekwondo. Heal is none. | [39] |
| Heel pain (plantar fasciitis) | none | Irritation of the tissue under the foot that often causes pain near the heel. | No evidence indicates regular taekwondo accelerates plantar fasciitis healing. Because taekwondo involves repeated foot-strike/weight-bearing, the safe default is none. | [58] |
| Rotator cuff irritation | none | Pain and overload in the shoulder muscles and tendons that help control arm movement. | No evidence supports healing benefit from routine taekwondo. Heal none. | [39] |
| Shin splints | none | Exercise-related pain along the shin that often appears when impact load rises too quickly. | No evidence that routine taekwondo practice improves healing of shin splints. Healing typically benefits from reducing irritative load; therefore heal is none. | [45] |
| Shoulder impingement-type pain | none | Shoulder pain that appears when tissues feel pinched or irritated during arm elevation. | Heal none by default. | [39] |
| Shoulder instability or dislocation | none | A shoulder that has slipped out, partly slipped out, or feels unreliable in vulnerable positions. | No evidence supports healing benefit from continuing taekwondo. Heal none. | [39] |
| Back stress reaction (spondylolysis) | none | A stress injury in the back often linked to repeated extension and rotation loading. | No evidence supports that regular taekwondo participation accelerates healing of stress-reaction/spondylolysis. Therefore heal is none. | [39] |
| Tennis elbow | none | Pain on the outside of the elbow linked to overload in the wrist and forearm tendons. | No evidence suggests that continuing taekwondo helps healing of tennis elbow. Heal set to none. | [39] |
| Shin bone stress injury | none | Stress irritation in the tibia from repeated impact that has outpaced recovery. | No evidence supports that routine taekwondo practice heals tibial stress injury. Therefore heal is none. | [39] |
| Wrist sprain | none | A stretched or irritated wrist ligament, often after a fall, impact, or awkward bend. | Heal none due to lack of evidence and potential re-stress from arm-blocking and sparring. | [39] |
| Wrist tendon pain | none | Irritation of wrist tendons from repeated gripping, racquet use, lifting, or supporting body weight. | Heal none due to lack of evidence and risk of ongoing aggravation. | [47] |
Past-sport transfer logic
| Past sport | Average correlation (success) | Std dev | Correlation reasoning | Correlation sources |
|---|---|---|---|---|
| american-football-defensive-back | 0.15 | 0.12 | Defensive back performance should correlate weakly with taekwondo success because both benefit from explosive movement speed, quick reactions, and ability to manage distance through fast footwork. However, taekwondo is highly technique-specific: kicking mechanics, chamber/recoil timing, balance during high-speed kicking, and striking-pattern tactics are not trained in defensive back roles. Cue sets also differ—coverage reads vs striking-range timing. Therefore overall correlation is modestly positive but limited, with substantial variation driven by prior martial arts exposure and how quickly the athlete learns taekwondo-specific kicking technique and timing. | [60] [61] [62] [63] |
| american-football-line-player | 0.32 | 0.14 | PAST = American football line-player success (contact-heavy, explosive power, leverage/body positioning, and reactive performance under chaos). FUTURE = Taekwondo success (striking combat with high-speed kicks; needs timing, distance management, explosive leg mechanics, and perceptual-cognitive anticipation/decision-making). Why correlation is positive (raises r): shared requirement for operating under opponent-driven time pressure; football line players often have strong perceptual/response readiness and physical force expression, which can help with initial kick explosiveness and decision timing. Why it’s not high (lowers r): taekwondo’s dominant bottlenecks are highly sport-specific: kicking mechanics, distance control, and discipline-specific perceptual-motor patterns. Combat-sport research shows discipline-specific perceptual-motor profiles, constraining cross-sport prediction. Bayesian estimate: start with a moderate-positive prior from shared “duel under time pressure + power/explosiveness” traits, then discount for the large action-system/mechanics mismatch (kicking/distance/timing). This yields r ≈ 0.32 with std dev ≈ 0.14. | [64] [65] [66] [67] [68] |
| american-football-linebacker-tight-end | 0.15 | 0.1 | Linebacker/tight end success should correlate weakly but positively with taekwondo success because both benefit from explosive lower-body power, whole-body coordination, and the ability to execute under pressure. However, taekwondo is dominated by taekwondo-specific technical outputs: precise kicking speed, chamber-to-impact timing, balance during high-kick chambers, reach and scoring-distance control, and sparring tactical footwork. Those perceptual-motor patterns and repeatable kick mechanics are not typical primary determinants in LB/TE training. Contact/tackling leverage transfers partially to overall combat-athletic control, but it does not reproduce the exact kicking/distance-management technique. Therefore carryover is expected to be small-to-modest: a head start in athleticism and learning speed, but limited prediction of taekwondo technical sparring effectiveness. | [69] [70] [71] |
| american-football-quarterback | 0.39 | 0.15 | We’re estimating the correlation between (1) being successful as an **American football quarterback** and (2) being successful as a **taekwondo athlete** (technique/striking success), ignoring physique/proportional traits. Why it’s moderately positive (raises correlation): - **Perceptual-cognitive overlap:** QB expertise is strongly about early visual information pickup, anticipation, and rapid response selection under time pressure; Taekwondo success also depends on perception/anticipation of opponent action and fast response selection. ([sciencedirect.com](https://www.sciencedirect.com/science/article/pii/S146902921830668X?utm_source=openai)) - **Attentional control under volatility:** both settings have high uncertainty (defense/offense in football; opponent feints/tempos in taekwondo), which can translate as a learning advantage. ([pmc.ncbi.nlm.nih.gov](https://pmc.ncbi.nlm.nih.gov/articles/PMC11505547/?utm_source=openai)) Why it’s not high (lowers correlation): - **Action-affordance mismatch:** QB mechanics are throwing/pocket movement, while Taekwondo is striking with specific kicking kinematics, balance during chambered phases, and scoring-context constraints. Transfer literature emphasizes that perceptual-cognitive transfer is usually partial and attenuates with action differences. ([journal.uir.ac.id](https://journal.uir.ac.id/index.php/JSP/article/download/6433/3398/24997?utm_source=openai)) - **Technical execution bottleneck:** Taekwondo scoring is dominated by kicking speed/timing/accuracy and sport-specific technique, which is not pre-learned from quarterbacking. Bayesian calibration to a numeric value: - Start with a dissimilar-sport baseline for partial perceptual/decision transfer around ~0.25–0.35. - Increase slightly because Taekwondo (like other combat sports) is strongly perceptual-cognitive rather than purely physical, and contains response-selection and anticipation elements that match QB. ([sciencedirect.com](https://www.sciencedirect.com/science/article/pii/S146902921830668X?utm_source=openai)) - Cap below ~0.5 because most of the performance is still sport-specific striking mechanics. ([sciencedirect.com](https://www.sciencedirect.com/science/article/pii/S146902921830668X?utm_source=openai)) Result: **correlation_average ≈ 0.39**, with **std_dev ≈ 0.15** reflecting that conversion varies a lot depending on whether the QB’s success came from broader athletic/perceptual training versus mostly passing/throwing mechanics. | [72] [73] [74] [75] [76] |
| american-football-receiver-running-back | 0.16 | 0.1 | Receiver/running back performance should correlate slightly with Taekwondo success because both reward: (1) explosive kicking-range entry via quick acceleration, (2) balance and body control while moving fast, and (3) the ability to time an explosive action after reading what’s happening. However, Taekwondo performance is heavily determined by event-specific kicking technique and combat-timing: hip-to-foot sequencing, chambering speed, range management tailored to kicks, scoring/priority rule timing, defensive footwork, and counters. WR/RB roles train open-field movement and ball-route timing rather than chambered-kick biomechanics and striking/range tactics. Therefore the overall carry-over should be modest (~0.16) with meaningful uncertainty. | [77] |
| athletics-distance | 0.07 | 0.03 | Distance-running success should relate positively but weakly to later Taekwondo success. Transfer is mainly general: aerobic/anaerobic base for repeated bouts, fatigue resistance (staying composed and technique-consistent through longer sparring sessions), and training discipline/learning habits. However, Taekwondo performance depends heavily on sport-specific technical and perceptual skills: explosive kicking mechanics (chamber/retraction timing, hip/leg power application), reach-and-distance management to land kicks at scoring range, and rapid reactive timing during live sparring (including feints and counter timing). Distance-running technique provides minimal direct overlap with these. With technique/skills transfer only (and excluding body-type proportions), the expected correlation should stay low above the near-zero baseline. A plausible mean is ~0.07 with moderate uncertainty (roughly ~0.04–0.12). | [78] |
| athletics-jumps-high-jump | 0.13 | 0.09 | High-jump performance should correlate modestly with taekwondo success. The shared, transferable component is general technique-adjacent athleticism: explosive leg power, elastic use of the lower body, and strong body control, which can support fast kicking, jumping kicks, and quick repositioning. However, taekwondo is dominated by highly specific kicking mechanics (hip/ankle sequencing, chamber/recoil timing), plus open-skill adversarial timing, distance management, and reaction to an opponent’s movement cues—skills not trained well by high jump. Therefore the overall correlation is positive but limited and variable. | [79] [80] [81] |
| athletics-jumps-long-triple-jump | 0.13 | 0.12 | Long jump/triple jump performance reflects explosive lower-body power, elastic stiffness/recoil, and coordinated timing—these can modestly help Taekwondo because kicks require rapid force generation and well-timed leg extension/direction changes. However, Taekwondo success depends heavily on sport-specific technical learning: chamber/rechamber mechanics, precise footwork and stance control under pressure, kicking accuracy/control, and defensive/reactive timing with an opponent. Those are largely non-overlapping with jumping-event technique. Therefore the expected carry-over is small-to-modest positive with substantial uncertainty across individuals. | [82] [83] [84] |
| athletics-jumps-pole-vault | 0.11 | 0.09 | Pole vault success should have a small positive correlation with taekwondo striking success because both reward explosive lower-body power, timing, balance, and the ability to control and re-stabilize your body after committing to fast movements. However, taekwondo’s core performance is dominated by kicking-specific mechanics (chambering, hip/foot speed, reach/targeting), reactive distance management, and opponent-based timing—skills not developed by pole-vault training. Therefore the average carryover should remain modest (roughly ~0.05–0.20), centered near ~0.11, with meaningful variance depending on whether the athlete also trains kicking/striking skills alongside pole vault. | [85] [86] [87] |
| athletics-middle-distance | — | — | No explanation provided. | — |
| athletics-sprints-hurdles | 0.16 | 0.09 | Sprint/hurdle performance should have a modest positive relationship with taekwondo striking success. The carry-over is mainly through technique-relevant athletic components: explosive acceleration, leg stiffness/power expression, and the ability to manage short, high-intensity movement bursts and timing. However, taekwondo outcomes are heavily driven by sport-specific kicking mechanics, balance, and the perceptual timing of kicks against a resisting opponent—largely absent from sprint/hurdle training. Therefore the overall expected correlation is small-to-modest with meaningful variance based on how quickly the athlete learns taekwondo fundamentals and how much general martial-arts exposure they already have. | [88] [89] [90] |
| athletics-throws-discus | 0.15 | 0.07 | Discus performance reflects rotational strength, leverage use, rhythm/timing, and efficient whole-body sequencing into a fast ballistic release. Taekwondo’s kicking effectiveness similarly relies on generating and transferring power quickly from the ground through the hips/trunk to the kicking leg/foot, plus maintaining body control during rapid changes in position. That creates a meaningful positive association in general “explosive coordinated power” components. However, taekwondo’s dominant determinants are sport-specific: kicking technique (chambering, recoil, impact mechanics), timing and range management versus a moving opponent, stance/guard, and opponent-reactive decision-making. These limit discus-to-taekwondo transfer so the correlation should not be high. A realistic Bayesian estimate is a small-to-moderate positive correlation around ~0.15 with std dev ~0.07 due to variable cross-training in combat sports. | [91] [92] [93] |
| athletics-throws-hammer-throw | 0.1 | 0.06 | Hammer throw success indicates strong whole-body coordination, dynamic balance through a rotational movement, and efficient explosive force generation. Those can transfer meaningfully into taekwondo’s need for explosive kicking, body control, and stability while generating power. However, taekwondo success is heavily determined by sport-specific striking mechanics: chambered kick execution, precision targeting, distance management, reactive footwork, and timing against an opponent. Hammer throw’s implement-leverage rotational sequence does not train these combat- and targeting-specific skills. Net effect: a modest positive correlation, around the 0.1 range. | [94] [95] |
| athletics-throws-javelin | 0.14 | 0.09 | Javelin success is strongly associated with explosive whole-body sequencing (legs→trunk→upper body) and fast upper-body action, which can transfer somewhat to taekwondo’s needs for burst power, coordination, and timing of explosive movements. However, taekwondo is dominated by sport-specific determinants: kicking speed and accuracy, chamber-to-impact timing, rotational/hip mechanics for kicks, partner/opponent distance management, defensive/reactive movement in sparring, and balance recovery after kicks. Since javelin’s key technique is an overhand throwing release (arm/shoulder-driven) rather than repeated kick-based striking under combat timing constraints, the overlap is partial. Net expected carry-over is small but positive, plausibly around ~0.14 on average with moderate individual variation. | [96] |
| athletics-throws-shot-put | 0.2 | 0.12 | Shot put success reflects maximal whole-body force production, trunk bracing, and coordinated explosive movement. These qualities should help taekwondo for the physical side: generating explosive kicking power, maintaining stable balance during rapid attacks, and moving efficiently through explosive distance-management footwork. However, taekwondo performance is dominated by sport-specific learned skills: kick chambering/extension mechanics, precise timing to impact, stance and footwork patterns, and tactical range control against an opponent. Those key learned determinants have limited overlap with shot-put throwing mechanics. Therefore the correlation should be positive but only modest, with substantial individual variation depending on how quickly the athlete acquires taekwondo footwork and kick timing. | [97] [98] [99] [100] |
| badminton | 0.08 | 0.05 | Badminton should have a modest positive correlation with taekwondo success because both benefit from fast reaction timing, good footwork/stance control, and learning to time explosive movements at the right moment. However taekwondo is dominated by highly specific kicking mechanics, distance management with kicks, and combat-timing under an opponent’s attacks—none of which are trained directly by badminton. Therefore the carry-over should be small. Plausible estimate: ~0.04–0.12 with an average around ~0.08. | [101] |
| baseball-catcher | 0.08 | 0.06 | Baseball catcher success should have a small positive relationship with taekwondo success. Shared transferable components: - Fast perception and reaction to a moving object (catching/tracking translates conceptually to reading an opponent’s action) - Timing and coordination of a technically coached movement executed under pressure - Basic lower-body stability from the crouched receive/block position and transitions - Composure and routine-based learning from repeated high-pressure reps Why the carryover is limited: - Taekwondo performance is dominated by sport-specific striking skills: kicking speed and mechanics, chambering and extension timing, hip/ankle coordination for kicks, and repeated explosive kicking under sparring constraints. - Footwork and distance management (enter/exit range, angle creation) and sparring tactics are very specific to taekwondo. - Catcher’s receiving/blocking/throwing does not directly train the neuromuscular patterns for kicking and the timing of strike exchanges. So the correlation should be low but not zero, with moderate variance: athletes with exceptional general athleticism and quick motor-learning may adapt faster, while others may not. | [102] |
| baseball-field-player | 0.07 | 0.06 | Baseball field players and taekwondo athletes overlap mostly in general “read early + react fast + stay coordinated” abilities. Baseball also trains stress management during live, chaotic moments and repeated effort over many innings. However, taekwondo performance is highly technique-specific: kicking speed and accuracy depend on hip-to-foot timing, chamber mechanics, balance during unilateral impacts, sport-specific defensive footwork, and sparring distance control. Those are not trained directly by baseball fielding. So the carryover should be small-to-modest and variable, with many athletes near baseline unless they also train martial arts or have prior kicking/striking background. A plausible estimate is ~0.07 average with ~0.06 std dev. | [103] [104] |
| baseball-pitcher | 0.07 | 0.06 | Pitcher → taekwondo should yield a small positive carryover at most. Shared transferable elements are mostly general: explosive execution, coordinated timing, and training discipline to refine a repeatable technique under pressure. A pitcher’s neuromuscular coordination and ability to accelerate/stop quickly can modestly help with learning kicking timing and generating leg power. However, taekwondo’s core technique is highly sport-specific: chamber/retraction mechanics, kicking geometry (speed at impact from different ranges), footwork and stance timing, and offensive/defensive distance management. Overhand throwing mechanics do not map directly onto kicking and combat patterns. With body-proportion traits excluded, the expected average correlation remains low (around the 0.05–0.10 range). I set the mean at ~0.07 with moderate uncertainty. | [105] [106] [107] |
| basketball-big | 0.12 | 0.06 | The correlation from basketball Big to taekwondo is small but positive. Shared components include explosive lower-body power, coordination, and the ability to move and stay balanced during rapid actions. However, taekwondo’s decisive determinants are highly technique-specific kicking mechanics, footwork/stance timing, and rule-based distance management—skills not central to basketball Big play. Excluding body-proportion traits, this keeps the correlation in the low tenths (~0.10–0.15). | [108] [109] |
| basketball-guard | 0.1 | 0.08 | Basketball guards share several transferable technical ingredients with taekwondo: fast lower-body movement, balance, coordination, and the ability to time actions to an opponent’s spacing and movement. That creates a small head start for learning taekwondo footwork and timing. However, taekwondo performance is dominated by event-specific skills: kicking speed and mechanics (chambering, hip/ankle sequencing, strike trajectories), combative distance/range judgment, and guard/defensive actions with the ruleset of sparring. Basketball guard play doesn’t meaningfully train those kicking/strike mechanics. So the carryover should be small positive with substantial individual variation. | [110] [111] |
| basketball-wing | 0.1 | 0.08 | Basketball wing performance should have a small-to-modest positive correlation with taekwondo success due to shared general attributes: explosiveness, balance, coordination, and timing. However, taekwondo is dominated by sport-specific kicking technique, chambering mechanics, and striking distance control that basketball does not teach directly. Thus the expected correlation is modest: ~0.10 average with ~0.08 uncertainty. | [112] [113] [114] [115] |
| boxing | 0.7 | 0.18 | Boxing should have a strong positive correlation with taekwondo success because both are striking combat sports that strongly depend on distance management, timing, reading an opponent, and composure under direct threat. Many boxing perceptual-motor habits (tracking movement, creating/evading openings, maintaining balance while engaged) carry over. The correlation is not near-perfect because taekwondo’s key technical primitives are different: kicking speed and mechanics (chambering, hip/leg generation, foot targeting), distinct stances and footwork patterns for kick range, and rule-specific tactical choices. Overall this yields a high average correlation with substantial variance: some athletes adapt quickly, others find the kicking-specific skill requirement limiting. | [116] [117] [118] [119] [120] |
| climbing-bouldering | 0.12 | 0.09 | Bouldering success is associated with strong body tension/bracing, balance/proprioception, and the ability to generate force quickly while keeping precise coordination. These can transfer to taekwondo as improved stability, better control of whole-body mechanics during explosive kicks, and faster motor learning. However, taekwondo success depends heavily on sport-specific determinants: kick chambering and recoil timing, hip/torso alignment for force generation, precise target-distance management, and reacting to an opponent’s movement while executing legal strike patterns. Bouldering does not train those striking and opponent-coupled mechanics. Therefore the carryover should be positive but modest with meaningful variability based on how much the bouldering background includes dynamic footwork and kicking-like explosive leg actions versus mostly upper-body/grip strength. | [121] [122] [123] |
| climbing-lead | 0.13 | 0.08 | Lead climbing success is driven by movement economy, balance/proprioception, and keeping precise body positioning as forearms/grip fatigue and pump discomfort increase. Taekwondo success depends heavily on sport-specific skills: explosive kick mechanics, timing, recoil control, distance management, and opponent-reactive striking/defensive decisions. Shared overlap is mainly general: (1) body control and coordination, (2) maintaining technique-quality under fatigue/discomfort, and (3) fast learning from feedback. But the dominant ‘how to win’ actions in taekwondo (kicking speed/accuracy, sparring timing, managing range) are not trained by lead climbing’s friction/grip-based movement. So the correlation should be positive but modest. A realistic Bayesian-style estimate is ~0.13 with std dev ~0.08 to reflect wide individual variability (e.g., some climbers may also have prior martial arts or leg power training). | [124] |
| climbing-speed | 0.22 | 0.1 | Speed climbing success indicates explosive upward acceleration, precise neuromuscular coordination, balance, and repeatable execution under time pressure. Taekwondo also relies on explosive bursts—especially for kicking speed and recovery—as well as disciplined body control and footwork quality. Because these share meaningful neuromuscular/athletic components (explosiveness, coordination, tension control), a modest-to-moderate positive carry-over is plausible. However, taekwondo’s key determinants are highly technique- and adversarial-specific: chamber timing, kicking mechanics, stance transitions, and strike timing based on opponent reads. Speed climbing’s hold-based sprinting mechanics have limited direct overlap with kick/striking technique. That keeps the correlation from being high. A realistic estimate is in the ~0.15–0.3 range, centered around ~0.22. | [125] [126] [127] |
| cricket-all-rounder | 0.08 | 0.06 | Cricket all-rounder success should have a small positive correlation with Taekwondo mainly through transferable timing/distance judgment and general ability to execute explosive bursts with coordination. However, Taekwondo is highly technique-specific: kicking mechanics, chamber/extension timing, defensive footwork, and rules-based range control are not learned in cricket. With body-trait/reach confounds excluded, only a limited learning/mentality component carries over, keeping correlation low (~0.08). | [128] [129] [130] [131] [132] |
| cricket-batter | 0.11 | 0.06 | Cricket batter success depends heavily on perceptual timing (reading a moving ball early), hand–eye coordination, and stable lower-body control to execute repeatable striking mechanics. Taekwondo success also depends on timing and explosive movement, particularly for initiating kicks from a set stance and managing distance and reach to land efficiently. The main overlap is general: coordination, balance, and the ability to time an action accurately under pressure, plus repeatable mechanics for producing powerful lower-body actions. But taekwondo’s key motor programs are event- and combat-specific: chambering and snapping mechanics, hip/torso kinematics for kicks, footwork patterns (step/angle management), and reactive decision-making in an opponent-driven environment. Cricket batting does not meaningfully train those specific kicking/stance and combat timing loops. Therefore the correlation should be positive but modest. | [133] |
| cricket-bowler | 0.08 | 0.08 | Cricket bowler → taekwondo is expected to be weakly positive. Direct technique transfer is limited because bowling’s overarm projectile mechanics don’t map well to taekwondo’s kicking-based timing, distance control, and combat footwork. The main overlap is higher-level perception-action timing and general explosive/iterative high-intensity execution. Since taekwondo outcomes are dominated by highly specific kicking and distance/defense mechanics, the correlation should remain small. A Bayesian point estimate around 0.08 with std dev ~0.08 is consistent with “small head start via timing/learning, but capped by major motor-program mismatch.” | [134] [135] [136] [137] [138] |
| cricket-wicketkeeper | 0.12 | 0.1 | Cricket wicketkeeper success should correlate modestly with taekwondo success because both reward fast reaction timing, visual tracking, and explosive lower-body bursts from a ready posture. However, taekwondo is dominated by very specific kicking mechanics, timing to distance, and footwork/defensive patterns that wicketkeeping doesn’t train. Therefore carryover is positive but limited (low-to-mid 0.10s). | [139] [140] [141] [142] |
| cycling-mountain-bike-cross-country | 0.11 | 0.08 | Mountain bike cross-country should have a small but non-zero correlation with future taekwondo performance when ignoring body-size traits. The carry-over is mainly general athletic technique: balance/proprioception, coordinated lower-body movement, and the ability to repeat hard efforts and keep form under fatigue. However, taekwondo performance is dominated by technique-specific kicking mechanics, kicking speed/accuracy, chambering and extension timing, sparring distance control, and reaction to opponent cues—none of which MTB XC teaches directly. This specificity gap keeps the correlation low rather than moderate. | [143] [144] [145] |
| cycling-road-climber | 0.08 | 0.09 | A cycling road climber’s key strengths are sustained aerobic power-to-weight, pacing, and maintaining output when fatigued. Taekwondo success is more dependent on explosive kick speed, timing, distance management, and repeat high-intensity striking while managing recovery—skills with limited direct overlap. Some indirect benefits (general coordination, leg strength base, and training discipline) likely provide a small advantage for learning. Overall, the expected carry-over is low (around 0.08) with substantial person-to-person variability depending on flexibility and prior martial-arts exposure. | [146] [147] [148] [149] |
| cycling-road-sprinter | 0.12 | 0.08 | Cycling road sprinter success should have a weak positive relationship with taekwondo success in a technique-only sense (excluding physique). There is some carry-over from explosive burst ability, training discipline, and general comfort with high-intensity effort. However, taekwondo outcomes are dominated by highly specific kicking biomechanics, distance control, and reactive footwork under opponent pressure—techniques with low overlap to cycling sprint mechanics. Therefore the carry-over correlation should remain small (around 0.12) with moderate uncertainty (std ~0.08). | [150] [151] [152] [153] [154] |
| cycling-road-time-trialist | 0.11 | 0.1 | Cycling road time-trial success should show a **small positive** relationship with taekwondo success. The overlap is mainly general athletic/conditioning: strong lower-body strength, ability to train hard and recover through fatigue, and some capacity for explosive leg power. However, taekwondo performance is dominated by sport-specific technical determinants—kicking mechanics and recoil timing, distance management (range judgment), fast reactive striking, and repeatable kick execution under pressure. Cycling TT does not meaningfully practice those kick-specific perceptual-motor patterns, so most variation in TKD outcomes should be unrelated to TT performance. Thus an average correlation around **0.11** with fairly high individual variability is realistic. | [155] [156] [157] |
| cycling-track-endurance | 0.1 | 0.06 | Cycling endurance should have a small positive carry-over to taekwondo. The overlap is mostly general athletic preparation: the ability to train consistently, sustain repeated hard efforts (rounds/sparring sessions), and maintain coordination under fatigue. But taekwondo success depends strongly on highly specific technical striking skills—kick mechanics (recoil, chambering, hip/ankle sequencing), precision distance control, rapid footwork patterns linked to kicking, and combat-timing/perception in response to an opponent. Because those are not taught by endurance track cycling, the expected correlation remains low. A realistic estimate is ~0.05–0.18 with an average around ~0.10 and moderate uncertainty. | [158] |
| cycling-track-sprint | 0.14 | 0.14 | Cycling sprint-track performance should have a modest positive carry-over into taekwondo via general neuromuscular explosiveness, leg power, and the capacity for repeated high-intensity exchanges. However, taekwondo success depends heavily on highly sport-specific striking mechanics: kicking distance/timing, chamber-to-impact sequencing, footwork patterns, and reactive sparring decisions—all of which cycling sprinting does not meaningfully train. Because of this technique mismatch and the open-skill reactive environment, the technique-only correlation should remain small-to-moderate, plausibly ~0.14 with substantial uncertainty (~0.14). | [159] [160] [161] |
| fencing-epee | 0.24 | 0.12 | Epee and taekwondo should show a moderately positive correlation. The main transferable technique/cognitive components are: (1) managing striking range (distance/angle), (2) timing your entry/extension/attack to an opponent, and (3) reactive footwork and whole-body coordination in response to an opponent’s movement. The correlation is not extremely high because taekwondo’s execution is dominated by different tool mechanics: kicking dynamics (leg swing generation, chambering, kicking trajectories), specific guard/stance habits for kicks, and different rule constraints and rhythms (continuous striking threats rather than blade point touches). Those must be retrained. Net estimate: ~0.24 average technique correlation with moderate individual variance (std dev ~0.12). | [162] [163] [164] |
| fencing-foil | 0.4 | 0.2 | Foil fencing should correlate fairly strongly with taekwondo striking success because both are opponent-mediated combat sports where technique-neutral elements transfer: reading intent early, managing distance/reach, timing explosive entries, and maintaining composure through rapid exchanges. The correlation is not extremely high because taekwondo’s decisive skills are kicking mechanics (chambered leg drive, recoil timing), stance and footwork patterns optimized for kicking range, and striking/contact rules that differ from foil’s non-contact point control and priority logic. That creates a meaningful “re-learning” component and thus reduces the ceiling and increases variance. | [165] [166] [167] |
| fencing-sabre | 0.25 | 0.18 | Fencing sabre and taekwondo both train “combat timing”: reading an opponent, choosing when to enter, and executing fast, decisive actions while managing distance. Sabre also builds quick reaction, explosive starts, and movement coordination that can translate into better initiation and timing of attacks in taekwondo. The correlation is not very high because taekwondo’s core technique is fundamentally different: leg chambering, kick execution, kicking footwork patterns, and rule-specific scoring/combination rhythms are not meaningfully trained in sabre. Also, sabre’s target mechanics and weapon-mediated range control differ from striking with kicks. Overall this supports a moderate positive correlation, roughly in the mid-0.20s, with substantial uncertainty. | [168] |
| field-hockey-goalkeeper | 0.1 | 0.07 | Field-hockey goalkeeper and taekwondo share some transferable process skills: fast visual tracking, early reading of an opponent’s actions, quick reaction timing, and staying composed while moving in space under pressure. But taekwondo’s technical center of gravity is different: it relies on kicking-speed mechanics, precise timing at specific ranges, chamber/hip sequencing, and sport-specific defensive/range management. Hockey goalkeeping teaches stick/leg shot-stopping and goal-area positioning, not chambered kicking patterns. Therefore the expected correlation should be low-to-modest positive, mostly driven by perceptual timing and general footwork rather than direct technique overlap. | [169] [170] [171] [172] |
| field-hockey-outfield | 0.1 | 0.1 | Field-hockey outfield success should have a weak positive correlation with taekwondo success. The shared transferable component is mainly general perceptual-motor timing and athleticism: reacting to an opponent’s movement, coordinating body segments quickly, producing explosive leg actions, and keeping technique under fatigue. However, taekwondo success is strongly technique- and situation-specific: chambering/recoil patterns, kicking mechanics and accuracy at range, defensive footwork, and combat timing. Those technical elements are not trained in hockey outfield roles. Therefore the correlation should remain low (roughly ~0.00–0.20), centered near ~0.10 with moderate uncertainty. | [173] [174] |
| golf | 0.08 | 0.06 | Golf-to-taekwondo should have a modest, but not strong, positive correlation when body-trait effects are excluded. The carry-over is mainly general: striking/impact technique learning, disciplined practice habits, and the ability to time an action precisely. However, taekwondo success depends heavily on kick-specific motor patterns (hip/leg sequencing, balance, chambering), explosive distance management, and reactive opponent-driven timing in sparring. Since these are not trained by golf, the correlation should stay limited rather than high. | [175] [176] [177] [178] [179] |
| gymnastics-artistic | 0.24 | 0.11 | Artistic gymnastics should correlate positively with taekwondo success because there is substantial overlap in transferable *technique components*: whole-body coordination, extreme balance and body control, explosive lower-body mechanics, and the ability to execute high-amplitude movements accurately. However, taekwondo performance is dominated by sport-specific determinants: correct chambering and alignment for kicks, timing/feinting and scoring rules under sparring pressure, and defensive distance management. These are only indirectly related to gymnastics, so carryover should be moderate rather than extremely high. | [180] [181] [182] |
| gymnastics-rhythmic | 0.08 | 0.08 | Rhythmic gymnastics should correlate positively with taekwondo through transferable prerequisites: excellent balance, proprioception, flexibility/line control, and coordinated whole-body movement. These can help with stance stability, recovery after kicks, and the learning speed of kicking sequences. However, taekwondo performance is dominated by highly sport-specific determinants: explosive and efficient kicking biomechanics, precise distance management, repeated chamber/retraction speed, and opponent-based stimulus–response timing under resistance. Rhythmic gymnastics does not provide comparable practice for those adversarial and kicking-specific loops. Therefore the expected carryover is small but positive. A plausible Bayesian mean is ~0.08 with std dev ~0.08 due to wide athlete-background differences. | [183] [184] [185] [186] |
| gymnastics-trampoline | 0.18 | 0.1 | Trampoline should have a modest positive correlation with taekwondo success. Transfer is mainly general neuromotor skill: balance, proprioception, and the ability to control whole-body position quickly, which supports taekwondo footwork and kicking chamber/recovery coordination. Elastic timing/power can also help with explosive bursts and distance management. However, taekwondo performance is dominated by highly sport-specific technique: the exact kicking mechanics, chamber/impact timing, and the ability to land strikes accurately and defensively against an opponent. Trampoline does not directly train these kicking and opponent-driven perception-action decisions. Therefore the overall correlation is likely modest (low-to-mid 0.1s), around ~0.18, with meaningful uncertainty. | [187] [188] [189] [190] [191] |
| handball-backcourt | 0.2 | 0.12 | A positive correlation is plausible because handball backcourt success often reflects: - Strong perception-action timing (choosing the right moment to act). - Distance judgment (spacing from opponents/defenders). - Explosive burst coordination and repeatable high-tempo execution. - Confidence and technical composure under pressure. These qualities can carry over into taekwondo striking (kick speed/reach/timing). However, the dominant technique transfer is limited: - Handball backcourt is primarily arm-based throwing/shooting and perimeter ball tactics. - Taekwondo is heavily kicking-mechanics and footwork specific (hip/leg chain, chamber timing, “snapping” speed, guard management, engagement/reaction in combat). Because technique-specific leg mechanics and combat footwork are not trained by handball backcourt, the correlation should be moderate at most, around ~0.20, with substantial individual variability (std dev ~0.12). | [192] |
| handball-goalkeeper | 0.08 | 0.06 | Handball goalkeeping can correlate modestly with taekwondo because both reward rapid perception-action coupling, quick reaction, composure under pressure, and coordinated explosive movement. A goalie’s ability to read threat early and respond correctly can help with taekwondo’s timing and distance management. However, taekwondo performance is dominated by striking technique—kicking speed/power, chamber timing, exact footwork patterns, and defensive counter-timing. Those are highly specific and are not trained in handball goalkeeping. This technique mismatch limits the ceiling. Overall expect a small positive correlation. | [193] [194] |
| handball-pivot | 0.06 | 0.05 | Handball Pivot success depends on rapid explosive actions, strong body bracing/balance in tight physical space, and coordinated timing for effective passes/shots under pressure. Taekwondo success is dominated by sport-specific kicking mechanics (leg chamber/recoil, hip- and knee-driven power transfer), precise striking timing, reach/distance management, and combat-rule tactical patterns. There is some transferable component: explosiveness, coordination, and learning to execute well under pressure. But the core discriminative skills for taekwondo are largely different from pivot play, so the carryover should be small rather than moderate. | [195] |
| handball-wing | 0.13 | 0.08 | Handball wing and taekwondo overlap in opponent-interaction skills: quick perception of threat/space, timing commitments, and explosive distance changes. That yields a modest positive correlation. But taekwondo’s decisive technique is highly sport-specific: chambering and kicking mechanics, footwork patterns, stance control, and scoring techniques with specific distance/angle constraints. Handball wing training emphasizes throwing/shooting and ball targeting, so the exact motor programs for kicks and taekwondo distance control don’t transfer directly. Therefore the carryover stays modest and variable. | [196] [197] [198] |
| ice-hockey-defenseman | 0.1 | 0.08 | Ice hockey defenseman success should correlate modestly with taekwondo success because there is overlap in general, non-body-type skills: managing distance, staying balanced and coordinated under pressure, and executing actions with good timing against an opponent. However, taekwondo’s key technical determinants are highly sport-specific: kicking speed/accuracy, chambering mechanics, hip-driven explosive distance management, and sparring strategy under taekwondo rules. Ice hockey defense does not provide a technical foundation for those kicking/striking mechanics. Since the correlation is intended to reflect skill/learning transfer (not physical traits like reach), this caps the relationship. Therefore the expected correlation is positive but modest (~0.10) with fairly wide uncertainty. | [199] [200] [201] [202] |
| ice-hockey-forward | 0.1 | 0.07 | Ice-hockey forwards and taekwondo share some transferable technique-adjacent learning components: fast visual scanning, timing of commitment, and coordinating body segments to produce an explosive action in response to an opponent’s movement. That supports a small positive correlation. However, taekwondo success is dominated by highly sport-specific mechanics—kicking chamber/extension timing, reach management, stance mechanics, and defensive kicking/footwork patterns. Hockey forward technique (skating + stick/puck play) doesn’t train those motor programs. Therefore carryover remains low-to-modest rather than high. | [203] [204] [205] |
| ice-hockey-goalkeeper | 0.08 | 0.06 | Ice hockey goalkeeping is strongly built around fast visual tracking, reactive timing, and maintaining balance/repositioning after sudden threats. Those ingredients can carry over modestly to taekwondo because taekwondo also requires reading an opponent’s movement early, reacting quickly, and managing explosive distance changes without losing posture. However, taekwondo success is dominated by sport-specific striking mechanics: kicking speed and mechanics (hip-knee-ankle sequencing), chamber control, timing of impact relative to opponent range, spin/rotation techniques, and learning safe distance management and combinations. Goaltending does not teach these kicking motor programs or combative footwork patterns. So the expected correlation is positive but small, with meaningful spread: some goalkeepers adapt well to combat footwork and explosive extension, while others struggle mainly due to missing specialized kicking/striking technique and rule-specific tactical learning. | [206] |
| judo | 0.35 | 0.15 | Judo and taekwondo share substantial opponent-interaction overlap at the *skill* level: (1) maintaining balance while being off-centered and disrupted, (2) explosive whole-body reorientation to engage/re-engage, (3) reading timing and reactions from an opponent, and (4) footwork and distance management to initiate scoring opportunities. However, taekwondo success depends heavily on striking- and kicking-specific techniques (kicking chambers, hip/foot biomechanics, repeatable kick timing at range, and the sport’s distinct defensive/offensive patterns). Judo training does not directly teach those kicking/guard mechanics. Therefore, we expect a moderate-to-strong positive carry-over, but not near-maximal prediction of taekwondo ranking. A realistic estimate is around 0.30–0.40 (center ~0.35). | [207] [208] |
| lacrosse-attacker | 0.09 | 0.1 | Lacrosse attacker performance should have a weak positive association with taekwondo success through transferable perceptual skills (timing, distance judgement) and general comfort with explosive actions under pressure. However, taekwondo is dominated by highly specific kicking mechanics, stance/guard footwork, and sparring-rule constraints. Lacrosse attacker techniques do not train those kick-specific and guard-specific skills, so the correlation remains low with substantial variance. | [209] [210] [211] |
| lacrosse-defender | 0.1 | 0.07 | Lacrosse defender success should correlate positively with taekwondo performance to a small-to-modest extent. Shared transferable components include: (1) spatial/distance awareness and reading an opponent’s intentions, (2) quick explosive lower-body bursts, and (3) staying composed while engaging physically and reacting fast. However, taekwondo is dominated by highly technique-specific striking skills: kicking mechanics (chamber, hip/leg sequencing, extension timing), defensive footwork and guard management, scoring timing based on taekwondo rules, and learned sparring patterns for creating and countering kicking opportunities. Lacrosse defending uses stick checks and different body mechanics and doesn’t meaningfully train the exact kicking/stance/chamber timing or sparring distance-management of taekwondo. So only a fraction of the variance should transfer, keeping correlation modest around ~0.1. | [212] |
| lacrosse-goalkeeper | 0.09 | 0.06 | Lacrosse goalkeeper success should correlate only modestly with Taekwondo because both benefit from quick perceptual processing, timing, balance, and staying composed during fast, high-pressure interactions. However, Taekwondo’s determinants are highly technique-specific (kicking mechanics, chamber/recoil timing, range/distance control, combinations, and guard/footwork patterns) that lacrosse goalie play does not train. The technical mismatch limits transfer, keeping the correlation in the low double digits. Estimated correlation: ~0.09 with moderate spread. | [213] [214] [215] [216] |
| lacrosse-midfielder | 0.1 | 0.07 | Lacrosse midfield success can correlate modestly with Taekwondo because both reward reading an opponent quickly, acting at the right moment in contested space, and generating explosive lower-body efforts repeatedly. However, Taekwondo performance is dominated by very sport-specific kicking technique (chamber/retraction timing, hip/foot mechanics), footwork patterns tailored to kicking range, and striking/tactical decision rules tied to Taekwondo scoring. Lacrosse midfielder skills involve stick handling/catching and different contact dynamics, so the technical motor programs for kicks transfer poorly. So the expected carry-over is positive but small: ~0.10 average with a fairly wide spread depending on whether the athlete has prior martial-arts exposure or naturally adapts to kicking mechanics. | [217] [218] [219] [220] |
| padel | 0.1 | 0.07 | Padel-to-taekwondo should correlate slightly positively because both require rapid perception and timing, and learning to choose when to commit (attack/return) based on cues from an opponent/object. A padel player often adapts quickly to learning new movement sequences and maintaining coordination while under pressure. However, taekwondo is heavily technique- and combat-specific: it depends on leg/hip kinematics for kicking speed and accuracy, chamber/recoil efficiency, explosive distance management in open space, and combat footwork/stance control. Padel’s racket-and-wall rebound striking does not provide meaningful practice for kicking mechanics or combat-range tactics. Therefore the carry-over remains modest with large individual variance. | [221] |
| pickleball | 0.16 | 0.08 | Pickleball should have a modest positive correlation with taekwondo success mainly through transferable timing/anticipation and general footwork/balance under reactive conditions. But taekwondo performance is dominated by sport-specific striking and defensive techniques (kicking mechanics, blocks, stance-specific movement) that pickleball does not train. Therefore the expected carry-over is small-to-moderate, around ~0.16 with substantial uncertainty. | [222] [223] [224] [225] [226] |
| rowing-lightweight | 0.08 | 0.06 | Lightweight rowing should have a small positive correlation with taekwondo success. The transferable part is mostly general athletic competence: coordination, balance, and the ability to keep form and rhythm through repeated training stress. But taekwondo performance is driven by highly sport-specific skills with limited rowing overlap: explosive kicking mechanics (speed, chambering, hip/leg sequencing), distance judgment for kicks, dynamic footwork and stance transitions, and reactive timing against an opponent’s movements and feints. Rowing’s cyclic stroke mechanics and aerobic/efficiency emphasis do not replicate these combat timing patterns. Therefore the expected correlation is low (around ~0.08) with meaningful variance depending on whether the athlete also trains kicking/plyometrics/footwork beyond rowing. | [227] |
| rowing-openweight | 0.12 | 0.07 | Rowing openweight success reflects coordinated whole-body force production in a cyclic rhythm plus endurance/efficiency and the ability to keep mechanics consistent under fatigue. Taekwondo success relies heavily on highly event-specific striking skills: explosive kicking speed, chamber-to-impact timing, distance management (range), footwork patterns for entering/exiting, and reactive combat decisions. Those decisive taekwondo determinants are not trained by rowing’s propulsion mechanics, so direct motor-skill transfer should be limited. However, there is still meaningful transferable foundation: whole-body coordination, posture control, and general ability to train high-intensity drills repeatedly. That can make learning taekwondo fundamentals easier. Therefore the expected carry-over is small but positive (low-to-modest ~0.12), not near-zero because general power/coordination and training tolerance provide some advantage, but clearly capped by the large technique gap in kicking and combat timing. | [228] [229] [230] |
| rugby-union-halfback-midfield | 0.16 | 0.14 | Rugby union halfback/midfield performance should show a modest positive correlation with taekwondo success because both reward fast perception, timing of commitment, explosive lower-body actions, and distance/space management. However, taekwondo is dominated by highly specific kicking and striking mechanics (hip/torso sequencing, chambering, kick chamber timing), plus guard and combat-pattern execution. Rugby’s passing/kicking distribution and collision play do not train these techniques directly. So only part of the rugby skill stack transfers (mainly coordination, foot speed, and some timing/distance-reading), making the expected correlation moderate-to-low with substantial individual variability. | [231] [232] [233] [234] [235] |
| rugby-union-loose-forward | 0.14 | 0.09 | Loose forward success should correlate modestly with taekwondo because both require high-intensity athleticism: explosive leg drive, good dynamic balance, and performing under physical pressure. However, taekwondo performance is dominated by highly specific striking mechanics and timing: exact kicking techniques (chamber, hip rotation, recoil timing), reach/distance management, and taekwondo-specific footwork patterns and defensive actions. Rugby contact and ruck skills don’t train those kick-specific motor programs. So the expected correlation is low-to-modest positive with substantial individual variance—rugby athletes with excellent natural kicking/coordination or prior martial-arts exposure adapt faster, while others are limited by learning the taekwondo technique and distance-timing system. | [236] |
| rugby-union-outside-back | 0.25 | 0.12 | Rugby union outside-back success should have a modest positive correlation with taekwondo success because both draw on explosive lower-body power, rapid footwork, distance/spacing awareness, and body control under pressure. However, taekwondo is dominated by highly technique-specific kicking mechanics (chamber/retraction patterns, hip/knee/ankle coordination, and scoring-timed execution) and sparring-rule-specific distance engagement. Rugby doesn’t provide comparable repetition for these core skills, so the carry-over should remain limited rather than high. | [237] [238] [239] [240] [241] [242] |
| rugby-union-tight-five | 0.12 | 0.1 | Rugby tight-five and taekwondo have only partial overlap in technique/skill domains once we exclude body-proportion advantages. Transferable components (positive): - Comfort operating under physical stress and repeated impacts. - Training discipline and the ability to repeat demanding efforts with consistent form. - Close-range body control and leverage awareness in contact situations, which can help adaptation to combat distance changes. But taekwondo’s determinants are largely sport-specific: - Kicking mechanics (hip/leg chambering, snap/extension timing), - precise striking distance management in measured bouts, - footwork patterns (stance changes, bounce), - and point-scoring/defensive read timing. Tight-five scrummaging doesn’t train those core kicking/striking motor programs. Therefore the correlation should be modest rather than high. An average around ~0.12 is plausible with substantial uncertainty (some tight-five athletes convert well if they already have good kicking/leg coordination; others will not). | [243] |
| skiing-alpine-speed | 0.09 | 0.08 | Alpine speed-event skiing should have a modest positive relationship with Taekwondo because it builds transferable athletic foundations: high-speed balance, ability to absorb/recover from forces, and general explosive leg power. These can make it easier to learn stance stability, stepping patterns, and generating force for kicks. However, Taekwondo performance is dominated by sport-specific technique and timing: precise chamber-to-impact sequencing, kick height/reach control, distance management, and opponent-driven reactive footwork and striking. Skiing does not train the exact kicking mechanics or the timing/distance constraints of martial arts. Balancing general movement transfer against the large sport-specific kicking-technique mismatch yields an expected carry-over that is small but positive: roughly ~0.09 with substantial person-to-person variability (~0.08 std dev) depending on whether the athlete also does martial arts, plyometrics, or kicking-focused training. | [244] [245] [246] |
| skiing-alpine-technical | 0.13 | 0.08 | Alpine technical skiing (slalom/giant slalom) builds strong dynamic balance, edge/stance control, and the ability to rapidly redirect force with the legs while maintaining posture under perturbation. It also reinforces timing of commitment during fast changes, which can transfer to taekwondo’s need for explosive distance management (closing range, kicking at the right moment) and stable body alignment before impact. However, taekwondo’s core technique is sport-specific: correct chambering and extension of kicks, hip/torso mechanics for impact, retraction speed, and repeated practice of kicking accuracy on a target/opponent—all of which skiing does not directly teach. The expected carry-over is therefore modest positive rather than strong. | [247] |
| skiing-cross-country | 0.1 | 0.05 | Skiing cross-country success correlates with aerobic capacity, movement efficiency, balance, and coordinated lower/upper-body control—useful in taekwondo for maintaining stance, footwork quality, and explosive movement quality across bouts. However, taekwondo performance depends heavily on sport-specific technical determinants: precise kicking mechanics (hip chambering, recoil timing, shin/foot impact alignment), reach-and-distance judgment, defensive/reactive head movement, and rapid execution of combinations under rules-specific constraints. Ski XC does not meaningfully train these perceptual-motor kicking patterns or the timing of chambered kicks. Therefore the carry-over should be small but positive, reflecting general athletic coordination and training discipline rather than direct technique transfer. A value around ~0.10 is plausible with moderate uncertainty. | [248] |
| snowboarding | 0.14 | 0.16 | Snowboarding and taekwondo share some technique-relevant motor prerequisites: dynamic balance, proprioception, and the ability to coordinate fast lower-body actions while re-centering after stance changes. That can make taekwondo’s early kick mechanics and overall body control easier to learn. But taekwondo performance is dominated by highly specific kicking/striking technique (chambering and hip/torso timing) and combat timing/decision-making in response to an opponent. Snowboarding does not train those repeatable striking mechanics, so the correlation cannot be high. Therefore, a low-to-modest positive correlation is plausible, around ~0.14 average with noticeable variability (~0.16). | [249] [250] [251] [252] |
| soccer-central-defender | 0.07 | 0.06 | Soccer central defender success should provide a small-to-modest advantage in taekwondo mainly through transferable opponent-reading, timing, reaction, and composure under direct challenge. However, taekwondo’s key determinants are highly sport-specific: kicking speed and mechanics, distance management footwork, chamber/recoil timing, and sparring tactical patterns. Soccer defending does not train those core technique patterns. Therefore the overall correlation should be low-to-modest, around ~0.07 with std dev ~0.06. | [253] [254] [255] [256] |
| soccer-central-midfielder | 0.12 | 0.09 | Central midfield success transfers modestly to taekwondo because both build footwork, balance, and the ability to read an opponent and act at the right moment in a fast duel. That creates a small positive correlation. However, taekwondo performance depends heavily on highly specialized kicking technique (chambering, extension sequencing, recoil timing), guard/blocks, and rule-specific distance control. Soccer does not provide much of this exact motor learning. Therefore the overall correlation remains low-positive rather than moderate. | [257] |
| soccer-goalkeeper | 0.1 | 0.07 | Soccer goalkeeper success should correlate somewhat with taekwondo success because both reward fast perceptual processing and timing, maintaining balance while moving explosively, and managing distance/intention under pressure. However, the technical motor patterns differ substantially: taekwondo scoring depends on chambering/hip mechanics, kicking biomechanics (roundhouse, side kick, axe kick), stance/guard control, and combat-specific footwork and timing—skills not trained by goalkeeping. So the expected carry-over is small but nonzero, driven mostly by general attributes (reaction, balance, explosiveness, learning in high-pressure contexts) rather than direct technique overlap: r≈0.10 with moderate uncertainty (std dev ≈0.07). | [258] |
| soccer-striker | 0.13 | 0.08 | Soccer striker success should correlate somewhat with taekwondo success because both reward explosive lower-body action, timing, and committing under pressure at the moment of attack. However, taekwondo’s dominant technical bottlenecks are sport-specific: disciplined stance/guard footwork, controlled kicking mechanics (chamber/retraction, snapping speed), precise distance management, and sparring/rule-based scoring patterns. Soccer finishing with the feet only partially overlaps with taekwondo kicks and does not teach the combat-specific defensive positioning and combination timing. Therefore the correlation should be positive but limited. | [259] |
| soccer-winger | 0.16 | 0.1 | Soccer winger performance should correlate only low-to-moderately with taekwondo success. Positive overlap comes from: (1) distance and timing concepts learned in one-on-one attacking, (2) quick, coordinated footwork and acceleration/deceleration, and (3) maintaining decision quality under pressure. However, taekwondo is dominated by highly specific striking technique—hip/leg chamber mechanics, kicking angles and recoil timing, explosive distance management for kicks (and often jumping kicks), plus defensive responses and sparring-based shot selection. Soccer winger training doesn’t systematically develop those martial-arts mechanics. Therefore the expected average correlation is modest (around ~0.16) with substantial variance: athletes who already practice martial arts, do lots of kicking/drills, or have strong general explosive leg skill may transfer more. | [260] [261] [262] [263] |
| softball-catcher | 0.07 | 0.07 | Softball catcher success should have a small positive relationship with taekwondo success. Shared transferable components include quick perception/anticipation, readiness/reaction from a low stance, and overall coordination for explosive movements. However, taekwondo performance depends heavily on sport-specific technical and tactical skills: kick execution mechanics (chamber-to-impact timing, recoil efficiency), precise distance management, taekwondo footwork and stance transitions, and sparring/point-strategy timing. Catcher training (pitch reception/blocking and defensive game control) does not build those core determinants. Therefore the correlation should remain low positive. | [264] |
| softball-field-player | 0.06 | 0.06 | Softball field-player success should have a small positive relationship with taekwondo success because both involve perceptual-motor skills (tracking what’s happening), quick reactions, and coordinated footwork/balance. However, taekwondo performance—especially kicking speed and scoring effectiveness—is dominated by taekwondo-specific techniques (chambering and extension mechanics, hip/torso alignment, recoil timing, defensive timing, and distance management within bouts). Since softball fielding doesn’t meaningfully train these mechanics, carryover remains low. Net: low but non-zero positive correlation. | [265] [266] [267] |
| softball-pitcher | 0.08 | 0.11 | A softball pitcher transfers some useful ingredients to taekwondo: (1) timing and coordination of complex body movements, (2) general kinetic-chain force transfer, and (3) comfort executing repeatable explosive actions under fatigue/pressure. However, taekwondo striking success is dominated by sport-specific kicking mechanics (chambering/rechambering, hip/leg drive angles), footwork/stance control, range management, and reactive timing against a moving opponent—skills only weakly connected to underhand pitching. Therefore the expected correlation is small but positive. | [268] |
| squash | 0.17 | 0.1 | Squash and taekwondo share several transferable components: fast perception of an opponent/ball trajectory, rapid stimulus–response, and explosive movement with frequent balance/weight shifts and quick footwork. However, taekwondo striking success—especially kicking speed and accuracy—is dominated by highly specific motor patterns: chambering mechanics, kick timing relative to opponent distance, rotational/hip-knee-ankle coordination for kicks, balance control during airborne impacts, and sparring-rule-based footwork/strategy. Squash involves racket strikes and multi-direction movement in a confined court, so while it can support general reactivity and athletic coordination, it does not train the core kicking mechanics or taekwondo’s specific distance management under sparring. Thus the correlation should be positive but modest. A realistic Bayesian-centered estimate is r ≈ 0.17 with std dev ≈ 0.10 to reflect limited technical overlap and meaningful individual differences in how much of squash success comes from pure explosive footwork/timing versus squash-specific racket skills. | [269] |
| surfing | 0.14 | 0.08 | Surfing should correlate modestly with later taekwondo success because there’s real overlap in transferable, technique-neutral components: dynamic balance, rapid re-centering after perturbations, coordination, and the ability to produce power from stable joint positions and then stabilize immediately. However, taekwondo performance depends heavily on taekwondo-specific technical skills: precise kicking mechanics (hip-knee-ankle sequencing), chamber/recoil timing, footwork/stance rhythm, range management for each kick type, and sparring-specific decision-making. Surfing does not directly train the repeated high-speed kicking motor patterns or the sport’s tactical timing against an opponent. Therefore the expected correlation is positive but limited, with substantial variance depending on whether the athlete also trains kicking, martial arts footwork, or general plyometric/leg power beyond surfing. | [270] |
| swimming-backstroke-middle-distance | 0.1 | 0.07 | Middle-distance backstroke success reflects rhythm, stroke economy, shoulder endurance, and maintaining efficient technique under fatigue—indicating strong general motor control and technique-learning habits. Taekwondo success depends on very sport-specific skills: rapid kicking mechanics (speed, timing, chamber/retraction), stance and balance control, distance management, and opponent-driven reactive sparring decisions. Shared overlap is mainly general athletic coordination and disciplined technique practice. Core technical mechanics and the adversarial stimulus-response loop differ substantially, limiting direct transfer. Therefore a small positive correlation is plausible: ~0.10 mean with moderate uncertainty (~0.07), reflecting that some swimmers adapt well to taekwondo learning due to coordination, while many still need substantial time to master kicking/stance and sparring timing. | [271] [272] [273] |
| swimming-backstroke-sprint | 0.11 | 0.07 | Sprint backstroke success should show a weak-to-modest positive correlation with taekwondo performance. The overlap is mainly general: both reward short-burst explosiveness, high-tempo execution, and maintaining technical coordination under intense effort. However, taekwondo is dominated by highly sport-specific skills—stance management, kicking speed and trajectory control, hip/leg sequencing, and timing based on an opponent’s actions. Backstroke sprint training does not directly build these motor patterns or the interactive distance/perception skills. Therefore, the technique/skill carryover should remain modest, with an average around ~0.10–0.15. | [274] [275] [276] [277] [278] |
| swimming-breaststroke-middle-distance | 0.12 | 0.06 | Middle-distance breaststroke success suggests strong general coordination, rhythm/timing, and disciplined technique under fatigue—skills that can help someone learn taekwondo fundamentals and stay technically consistent during training. However, taekwondo’s main determinants are sport-specific: explosive and well-timed kicks (recoil/chamber timing), stance transitions, balance recovery, and opponent-based reactive striking. Breaststroke’s movement mechanics and energy-system emphasis overlap only partially, so the carry-over should be low-positive rather than moderate-high. Net expectation: correlation around 0.08–0.16 (average ~0.12) with substantial individual variation depending on whether the athlete also develops explosive power and kicking-specific balance quickly. | [279] [280] [281] [282] |
| swimming-breaststroke-sprint | 0.1 | 0.05 | Sprint breaststroke success reflects strong whole-body timing (simultaneous arm–leg coordination), explosive lower-body force production for short bursts, and high technical discipline. Those general athletic/coordination qualities can help with taekwondo’s general requirements: moving explosively, learning technique details efficiently, and maintaining timing under speed. However, taekwondo performance is dominated by highly sport-specific determinants: kicking mechanics, striking a moving target with correct body positioning, distance management, and reactive decision-making in an opponent interaction setting. Swimming does not train those core striking mechanics and reactive timing cues. Therefore, the technique/skill carry-over should be small positive rather than moderate. | [283] [284] [285] |
| swimming-butterfly-middle-distance | 0.12 | 0.06 | Swimming butterfly middle-distance success is driven by water-specific propulsion/undulation coordination and maintaining rhythm/efficiency as fatigue accumulates. Taekwondo success is driven more by sport-specific kicking mechanics, explosive footwork, reach-distance timing, and striking execution under opponent pressure. Learned mechanics overlap only weakly, capping direct carryover. A small positive correlation remains plausible due to transferable substrate: whole-body coordination, kinetic-chain awareness, and the ability to keep technique quality under repeated effort/fatigue. Net expectation ~0.12 with moderate uncertainty. | [286] [287] [288] [289] |
| swimming-butterfly-sprint | 0.12 | 0.07 | Butterfly sprint success indicates strong explosive upper-body/whole-body power, good rhythm/timing, and the ability to keep mechanics reliable under very short, intense fatigue. Taekwondo also rewards explosive, well-timed movement and repeated high-intensity exchanges, requiring coordinated whole-body mechanics (especially hips/torso-to-kick sequencing) and maintaining technical output during pressure. There is therefore some overlap in general skill elements: power generation quickly, coordinated movement, and keeping technique from collapsing under fatigue. However, taekwondo performance depends heavily on sport-specific learned technique: kicking mechanics, stance and footwork patterns, head/body positioning for striking and defense, and tactical distance management. Swimming butterfly does not train these directly. Thus the expected carry-over should be modest rather than large. Plausible Bayesian estimate: mean ≈ 0.12 with std dev ≈ 0.07. | [290] |
| swimming-freestyle-distance | 0.08 | 0.06 | Swimming distance freestyle/front-crawl success is mainly associated with aerobic/threshold conditioning, efficiency, and maintaining coordination while fatigued. Taekwondo emphasizes explosive kicking speed, lower-limb chamber/recoil mechanics, timing/accuracy, and opponent-based distance management—skills with limited direct mapping from swimming propulsion. Excluding body-trait effects, the overlap is mostly indirect (general conditioning, trainability, and coordination), so the correlation should be small but non-zero: around ~0.08 with moderate uncertainty. | [291] [292] [293] |
| swimming-freestyle-middle-distance | 0.14 | 0.08 | Swimming middle-distance freestyle performance mainly reflects aerobic efficiency, pacing/effort regulation, and highly specific front-crawl propulsion technique. Taekwondo success depends much more on highly specific striking mechanics: stance control, kicking chamber-to-impact timing, kicking speed and accuracy, distance management, and explosive burst execution with rapid recovery between exchanges. Direct technical/mechanical overlap with swim propulsion is low. Still, there is a modest positive carry-over from general athletic qualities: coordination, balance, disciplined technique learning, and maintaining performance quality under fatigue. Because Taekwondo is more burst/anaerobic and technique-specific, the overall correlation should be low-to-moderate, around ~0.14 with substantial variance. | [294] [295] [296] [297] |
| swimming-freestyle-sprint | 0.12 | 0.07 | Sprint freestyle (front crawl) success reflects explosive power expression (starts/turns), high-rate whole-body coordination, and the ability to execute maximal-intensity technique briefly while maintaining control. Taekwondo also rewards explosive distance management and rapid, well-timed kicking actions with repeated bursts during sparring. That shared “explosive + coordinated + high-intensity tolerance” ingredient supports a small-to-modest positive correlation. However, taekwondo’s decisive determinants are highly sport-specific: chamber/footwork timing, kicking mechanics (hip/ankle extension sequences), stance transitions, and perceptual timing against an opponent’s movement. Swimming does not directly train these kicking and sparring mechanics. Therefore the expected correlation should remain low-to-modest with notable between-athlete variability. | [298] [299] [300] [301] [302] |
| table-tennis | 0.2 | 0.15 | Table tennis success should have a modest positive correlation with future Taekwondo success because both rely on rapid visual processing, precise timing, distance control, and short explosive coordinated actions. However, Taekwondo performance is dominated by combat-specific techniques—kicking mechanics (hip/leg sequencing, snap timing, alignment), guard/feint patterns, and learning to strike safely and effectively under contact pressure—skills that do not directly transfer from racket/spin contact. Overall expected carry-over is low-to-moderate: ~0.20 with moderate uncertainty (~0.15). | [303] [304] [305] [306] |
| tennis | 0.12 | 0.07 | Tennis should correlate modestly with taekwondo because both involve timing, distance judgment, and quick, coordinated lower-limb actions under time pressure. A good tennis background can improve general footwork, balance, and the ability to react quickly. However, taekwondo success is dominated by highly specific striking skills—kicking mechanics (chamber, hip/foot alignment, recoil), stance/guard discipline, sparring distance management, and explosive kicking sequences governed by taekwondo rules. Tennis does not train those combat-specific techniques, so carry-over should be limited rather than strong. | [307] [308] [309] |
| triathlon | 0.08 | 0.05 | Triathlon success should correlate only weakly with taekwondo success. Both can benefit from endurance for long training sessions and the ability to keep technique choices under fatigue, but taekwondo’s determinants are highly sport-specific: maximal kick speed and accuracy, precise timing (chamber/recoil and impact timing), explosive footwork to manage kicking range, and rapid decision-making in sparring. Triathlon does not train these striking and reactive distance skills directly, so carry-over remains small (~0.08). | [310] |
| volleyball-attacker | 0.09 | 0.08 | Volleyball attackers can transfer a small advantage to taekwondo via general technique/learning factors: explosive leg power, timing of movement, and balance/coordination in the air—useful for high kicks and rapid re-centering. However, taekwondo scoring and effectiveness depend on kick-specific mechanics (chambering and recoil timing), reach/distance management in a live striking duel, and defensive/combat sequence timing. Volleyball attacking doesn’t train those combat-specific motor patterns. So the expected carry-over is small but positive, around ~0.09, with moderate variability (~0.08) depending on whether the athlete also has prior martial arts/leg-kicking experience. | [311] [312] |
| volleyball-libero | 0.1 | 0.07 | Volleyball libero success can correlate slightly with taekwondo success because both benefit from: (1) fast reaction to an opponent’s actions, (2) agile footwork and balance maintenance, and (3) ability to stay coordinated while moving quickly and frequently changing directions. However, taekwondo performance is dominated by highly sport-specific striking skills: kicking speed/power depend on hip-thigh-shin sequencing, chamber mechanics, recoil timing, and precise distance management. Also crucial are martial-arts timing, guard structure, and attack/defense combinations learned through sparring—not trained by libero digging/reception. So the carry-over is positive but limited, around ~0.10. | [313] |
| volleyball-middle-blocker | 0.16 | 0.13 | A volleyball middle blocker trains fast anticipation, quick repositioning, and coordinated explosive lower-body actions timed to an incoming ball. Those traits can transfer to taekwondo as general “timing, coordination, and reaction under pressure,” and may help with kick speed and initial distance judgment. But taekwondo success depends heavily on sport-specific mechanics: kicking technique (hip/leg sequencing, chambering, balance on the supporting leg), accurate reach-distance calibration, and combat skills like guard discipline, feints, and timing exchanges against an actively moving opponent. Volleyball blocking/jumping is a different interaction (net-front, mostly vertical timing to a non-opponent ball) and doesn’t directly develop these combat-specific motor programs. Therefore the expected correlation is positive but modest. | [314] [315] |
| volleyball-setter | 0.07 | 0.08 | Volleyball setters and taekwondo share limited but transferable ingredients: (1) tracking an incoming object early, (2) timing coordinated body movement, and (3) executing skills under time pressure. However, taekwondo success is dominated by highly sport-specific technique and constraints: guarded stance control, balance during dynamic kicking, chambering and retraction timing, explosive hip-driven kick mechanics, and combat-specific distance management learned through sparring. Volleyball setting’s overhead two-contact ball placement does not meaningfully train these determinants. Therefore the expected correlation should be low but not zero, driven mainly by general timing/reactivity. A reasonable Bayesian estimate is ~0.07 with uncertainty ~0.08. | [316] [317] [318] |
| wrestling | 0.25 | 0.18 | Wrestling and taekwondo share a combat-sport foundation: both require managing range, reading an opponent’s intention, staying balanced while exchanging force, and executing explosive movements under pressure. Those transferable competitive/perceptual-motor skills support a moderate positive carry-over. But taekwondo’s success is heavily driven by sport-specific kicking mechanics (chambering/retraction, hip–knee–ankle timing), precise kicking distance control, and kicking-focused defense. Wrestling does not directly train those core striking patterns, so the correlation should be noticeably below “very similar sport” levels and remain highly variable. A plausible average is ~0.25 with a relatively large standard deviation (~0.18) due to big individual differences in how quickly athletes transition from grappling timing to striking mechanics. | [319] [320] [321] |
