Can shorter workouts boost soccer performance as much as long ones?

This study tested whether doing shorter, more frequent plyometric exercises (about 20 minutes, 3-4 times a week) works as well as traditional longer sessions (about 40 minutes, twice a week) for improving speed and jumping ability in elite under-19 soccer players during pre-season. Twenty-four players completed an 8-week program, and researchers measured their sprint times, jump height, and change-of-direction speed before and after. The goal is to help coaches decide if micro-dosed training is a good alternative when time is limited.
