Jumping your way to stronger arms? study tests Leg-to-Arm strength transfer
NCT ID NCT07339436
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether doing leg exercises like jumps can also improve upper-body strength and muscle size in teenage male basketball players. Fifty players aged 16-18 with at least 2 years of experience were split into groups doing either combined leg-and-arm plyometrics, arm-only exercises, or regular training. Over 8 weeks, researchers measured throwing distance, muscle thickness, hormone levels, and muscle electrical activity to see if leg training boosts arm performance.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Plyometric training (jump and push-up exercises)
- What this could lead to
- If successful, this could show that leg exercises alone can boost arm strength and muscle growth, helping coaches design more efficient training programs.
- What could go wrong
- This is a small, completed study in healthy teen athletes, so results may not apply to other groups. The effects on hormones and muscle activity are exploratory and may not lead to practical changes.
