Understand your training.

Healthy adults; general strength and power training. Supports progressive resistance training and goal-dependent loading. This library’s exact starting doses are coaching choices; it does not validate a complete touch programme.

Healthy adults; foundational prescription guidance. Historical guidance on strength, power and progression, read alongside the newer ACSM statement. Not a rehabilitation or youth prescription.

Elite sprinting; transfer to team sports requires judgement. Supports purposeful sprint practice, technical quality and adequate recovery. Exact drill sequences and distances here are coaching applications.

Dynamic preparation; mixed exercise populations. Dynamic movement can prepare range and performance. It does not establish an injury-prevention effect for each warm-up drill.

Multiple sports; programmes including Nordic hamstring exercise. Programme-level injury reduction supports considering progressive Nordic loading. It is not an individual guarantee or acute-injury treatment instruction.

Male football players; progressive adductor programme. Supports progressive adductor strengthening in the studied programme. Touch, women and alternative doses require cautious transfer.

One male and one female international touch team. Informs touch conditioning context. Team-average differences do not determine an individual athlete’s exercise level, speed threshold or training load.

Court and field sports; planned direction changes. Multiple training methods can support planned turning. Angle, entry speed and task specificity matter; planned cuts are not identical to reactive agility.

Mostly soccer and basketball; female samples underrepresented. Supports practising perception and action together. Evidence certainty and sport transfer limit universal dose claims.

Male touch players; a specified reactive-agility test. Provides touch-specific rationale for reactive demands. It does not validate this library’s games, camera timing or alternative tests.

Amateur mixed-gender touch players. Supports an intermittent, position-aware touch context while showing limited between-position differences for many measures. Avoid rigid positional stereotypes.

Aerobic interval programming across athletic contexts. Work duration, intensity and recovery affect the training stimulus. Example intervals are templates to individualise, not a single optimal touch prescription.

Team-sport repeated-sprint sessions. Repeated sprints create substantial acute fatigue. Keep conditioning goals separate from fresh maximal-speed development.

Female team-sport athletes; certainty varies by outcome. Supports including appropriate plyometric training for women. It does not establish one best contact count, drill or progression ladder.

Female athletes; jump outcomes. Supports potential jump improvement from plyometric programmes. Specific exercise selection and impact readiness still require coaching.

Structured rugby-union physical preparation programmes. Useful physical-preparation reference. Individual borrowed exercise concepts do not confer the injury reductions of the full studied programme, nor establish equivalent effects in touch.

Stretching interventions and joint range. Supports range-of-motion changes with repeated stretching. Extra range is useful only where it serves the athlete’s needs and does not guarantee injury prevention.

Post-exercise cool-down effects. Does not support broad claims that a cool-down prevents soreness or injuries. Use an optional brief transition for comfort and preference.

Post-operative ACL reconstruction; clinician-managed rehabilitation. Supports individual rehabilitation and multidimensional progression. It cannot be generalised to every knee injury or used as app-only clearance.

Acute lateral ankle sprain and chronic instability. Informs clinician-selected loading, balance and functional work after ankle sprain. Severity and restrictions determine the entry point.

Touch playing-rule discussion. Context for seven-metre defensive movement. This is not a current competition rulebook: verify local rules before using drill distances or interchange conventions.

Midportion Achilles tendinopathy. Supports condition-specific management and loading. Do not apply midportion guidance unchanged to insertional pain, rupture or surgery.

Athletes with hamstring strain. Informs injury assessment and rehabilitation. Exercise choice, lengthening demand and running exposure require an individual plan.

Patients with diagnosed patellar tendinopathy. Supports a progressive loading approach in the studied condition. Do not copy it as a universal knee-pain or post-operative pathway.

Adults with suspected or diagnosed rotator-cuff tendinopathy. Supports assessment-led nonsurgical care and rehabilitation. It does not cover every shoulder injury, instability episode or surgical restriction.

Eumenorrheic women; heterogeneous evidence. Does not justify a universal phase-based performance schedule. Use the athlete’s symptoms, preferences and observed response; avoid assumptions based on gender alone.

Children and adolescents under appropriate instruction. Youth need supervision and development-appropriate programming. Adult doses in this catalogue must not be automatically copied to under-18 athletes.

Return to sport after lateral ankle sprain. Readiness includes pain, ankle impairments, perception, sensorimotor control and sport function. A single hop score or elapsed time cannot replace review.

Tendinopathy trials. Isometrics are one loading option, not a guaranteed analgesic or universally superior exercise. Clinicians select angle, load and dose.

Healthy participants undertaking resistance training. Strength work can also support range. A separate mobility drill is not always necessary if the required range is already trained comfortably.
