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.
