New study: which strength training boosts soccer performance best?
NCT ID NCT07447258
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at two different ways of strength training in 24 teenage male soccer players. One method used speed of movement to guide training, while the other used the traditional approach of training until failure. After six weeks, researchers measured changes in strength, speed, jumping, and muscle size to see which method worked better.
