Can One-Legged isometric exercises boost soccer performance?
NCT ID NCT07556315
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether adding isometric strength exercises (like holding a squat against a bar) to an 8-week training program helps youth soccer players jump higher, sprint faster, and get stronger. Forty-one male players aged 15-19 were split into groups doing unilateral (one leg) or bilateral (both legs) isometric exercises, or just the regular program. The goal was to see which type of training works best and whether it reduces strength differences between legs.

Active substance
isometric strength training exercises
What this could lead to
If it works, this could help coaches design better training programs to improve young soccer players' performance and reduce muscle imbalances.
What could go wrong
This is a small, early-stage study with only 41 male players, so results may not apply to females or other sports. The training is just 8 weeks, so long-term benefits are unknown.
