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 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.
