Heavier Warm-Up, higher jump? testing weighted plyometrics in soccer
NCT ID NCT07755345
First seen Aug 10, 2026 · Last updated Aug 14, 2026 · Updated 4 times
Summary
This study tests whether adding a weighted vest during plyometric warm-up exercises improves vertical jump height more than doing the same exercises without extra weight. Young male soccer players will perform both weighted and unweighted conditioning sessions, with jump performance measured at several time points afterward. The goal is to see if the extra load offers a performance boost and how long any effect lasts, which could help coaches design better warm-ups.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Weighted and unweighted plyometric conditioning exercises
- What this could lead to
- If weighted plyometrics prove more effective, coaches could use them to boost explosive power before games and training.
- What could go wrong
- This is a small, early-stage study in a specific group, so results may not apply broadly. Adding weight could also increase injury risk.
