Comparing adaptive and static training for better physical performance

Using AI-generated Adaptive Training Recommendations to Improve Physical Performance

PHASE1 · The Swedish School of Sport and Health Sciences · NCT06145152

This study tests whether a flexible training plan that changes based on how athletes feel can help them perform better than a set training plan that stays the same.

What this trial studies

This study compares two training strategies for recreational athletes: an adaptive training approach that adjusts daily based on the individual's recovery status, and a static approach that follows a fixed regimen regardless of readiness. Over an 8-week period, participants will engage in home-based training guided by an online application, while undergoing thorough physiological assessments, including muscle biopsies and continuous monitoring of glucose levels, sleep, and heart rate. The goal is to determine which training method yields better improvements in maximal oxygen consumption and overall physical performance.

Who should consider this trial

Good fit: Ideal candidates are recreational athletes with a history of regular running and experience using wearable technology for training.

Not a fit: Patients with chronic diseases, recurrent injuries, or those unwilling to use wearable devices may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective training programs that enhance physical performance and recovery for athletes.

How similar studies have performed: While adaptive training approaches have shown promise in other contexts, this specific comparison of adaptive versus static training in recreational athletes is relatively novel.
