AI coach boosts bike performance in new study
NCT ID NCT07318233
First seen Jun 24, 2026 · Last updated Aug 18, 2026 · Updated 4 times
Summary
This study tests whether an AI coach that gives personalized encouragement during indoor cycling can help people ride harder. 120 recreationally active adults aged 18-40 will do a 20-minute time trial on a stationary bike. Some will get AI-powered affirmations, some will get fixed messages, and some will get no coaching. The goal is to see if the AI coaching leads to higher average power output.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- AI-delivered self-efficacy coaching (behavioral intervention)
- What this could lead to
- If it works, this could point toward a way to improve exercise performance using personalized AI coaching.
- What could go wrong
- This is a small, early-stage study that hasn't started yet. The AI coaching may not outperform simple encouragement, and results may not apply to other types of exercise.
