Bowlegs and agility: a new test for young footballers
NCT ID NCT07798869
First seen Sep 01, 2026 · Last updated Sep 04, 2026 · Updated 3 times
Summary
This observational study compares change-of-direction and reactive agility performance between youth football players with and without genu varum, commonly known as bowlegs. Researchers will measure lower-limb alignment and use the SpeedCourt system to test how quickly players change direction and react to visual cues. The study aims to see if leg alignment is linked to these performance measures. Participants are football players with at least five years of experience who train at least five days a week.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If a link is found, coaches might tailor training to help players with genu varum improve agility and reduce injury risk.
- What could go wrong
- This is a small observational study, so it cannot prove cause and effect. Results may not apply to all players or levels of play.
