NCT ID NCT07709104
First seen Jul 16, 2026 · Last updated Jul 17, 2026 · Updated 1 time
Summary
This study tests whether doing isometric squats with one leg at a time or both legs together improves jump height in highly trained male volleyball players. Fourteen athletes will perform bilateral squats, unilateral squats, or a light walk, then have their jump performance measured at several time points. The goal is to see which type of warm-up leads to better jumping, and whether the effect differs for two-legged versus one-legged jumps.
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 it works, this could help coaches and athletes choose the best warm-up strategy to improve jump performance in volleyball.
- What could go wrong
- This is a small, early-stage study with only 14 highly trained athletes, so results may not apply to other groups or real-game settings.
