BCAA boosts sprint and recovery in young soccer stars, study finds

This study tested whether a single dose of BCAA or L-arginine supplements could improve sprinting, agility, and recovery in 21 elite youth soccer players. Results showed that BCAA helped with short sprints, agility, and faster heart rate recovery after exercise, while L-arginine showed no clear benefit. The findings suggest these supplements may work better with long-term use.
