Research
Evidence-based summaries of the research shaping modern coaching: what the science says, and what it means in practice.
Each summary distils a body of peer-reviewed work into its practical takeaways for coaches and athletes. Summaries are editorial syntheses prepared by the institute, not original studies.
Endurance
Interval training remains one of the most efficient ways to raise aerobic capacity. Meta-analyses consistently show that structured high-intensity interval work produces comparable or superior improvements in VO2max to traditional steady-state training, in a fraction of the time.
Key finding
Short, repeated high-intensity intervals improve maximal aerobic capacity as effectively as much longer moderate sessions.
Recovery
Sleep is among the most powerful, and most neglected, recovery tools available to athletes. Studies across team and individual sports link extended sleep duration with measurable gains in reaction time, accuracy, and self-reported wellness.
Key finding
Athletes extending sleep report faster reaction times, lower injury rates, and better training tolerance.
Youth development
The long-standing myth that strength training stunts growth in young athletes has been repeatedly disproven. Supervised, technique-first resistance training is associated with stronger bones, better movement quality, and fewer sports injuries.
Key finding
Supervised resistance training in young athletes improves strength, motor skill, and injury resilience without harming growth.
Nutrition
Deliberately varying carbohydrate availability across a training week, fuelling hard sessions and training low on easier days, has emerged as a strategy for endurance adaptation, though evidence for performance benefit remains nuanced.
Key finding
Matching carbohydrate intake to training demand can improve endurance adaptations while preserving high-quality session output.
Recovery
Cold-water immersion reliably reduces perceived muscle soreness after hard sessions. However, growing evidence suggests routine cold exposure immediately after strength training can dampen the cellular signalling that drives adaptation.
Key finding
Cold immersion reduces post-session soreness but may blunt strength and hypertrophy adaptations when used habitually after resistance work.
Skill acquisition
Mental imagery, the vivid rehearsal of a skill, activates many of the same neural pathways as physical execution. Programs that pair imagery with physical practice show faster skill acquisition, especially when session time on the field is limited.
Key finding
Combining physical practice with structured mental rehearsal speeds up motor learning beyond physical practice alone.
Injury prevention
How quickly training load increases matters as much as how much is done. Athletes whose weekly load spikes sharply relative to their recent average show markedly higher injury rates, supporting gradual, monitored progression.
Key finding
Large week-to-week spikes in training load are consistently associated with elevated injury risk in team-sport athletes.
Nutrition
Total daily protein intake is the primary driver of muscle adaptation. Distributing protein evenly across three to five meals, with a pre-sleep serving, modestly improves muscle protein synthesis compared with skewed intake patterns.
Key finding
Total daily protein matters most; evenly distributing it across meals supports muscle maintenance and growth.
Endurance
Repeated exercise in hot conditions expands plasma volume, lowers heart rate at a given effort, and improves sweat response. Even short structured acclimatisation blocks produce meaningful competitive advantages in warm-weather events.
Key finding
One to two weeks of structured heat exposure measurably improves performance and safety in hot conditions.
Psychology
Brief, consistent mindfulness training helps athletes regulate pre-competition anxiety and sustain attention under pressure. Effects are most reliable when practice is habitual rather than a single intervention.
Key finding
Structured mindfulness practice reduces competitive anxiety and improves attentional control under pressure.
