Judo jump study: can simple ankle tape fix leg asymmetry?
NCT ID NCT07688330
First seen Jul 07, 2026 · Last updated Jul 08, 2026 · Updated 1 time
Summary
This study looks at whether taping the dominant ankle can reduce differences in how the left and right legs work during a jump test in healthy judo athletes. Forty judokas aged 18 to 35 will perform countermovement jumps with and without ankle tape, and a force platform will measure leg symmetry. The goal is to understand if taping can help balance leg use, which may aid injury prevention and performance.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Standardized ankle taping
- What this could lead to
- If taping reduces asymmetry, it could help coaches and athletes use taping to prevent injuries and improve jump performance.
- What could go wrong
- This is a small, short-term study in healthy athletes. Results may not apply to injured athletes or other sports, and taping might not show a clear benefit.
