Branched-Chain Amino Acids Supplementation Does Not Accelerate Recovery after a Change of Direction Sprinting...

Area of Science:

• Sports Science
• Exercise Physiology
• Nutrition Science

Background:

• Branched-chain amino acids (BCAAs) are popular supplements for post-exercise recovery.
• Evidence is lacking on BCAAs' effects on muscle damage and recovery following change of direction (COD) sprinting, common in team sports.

Purpose of the Study:

• To investigate the impact of BCAAs supplementation on muscle damage markers, soreness, neuromuscular performance, and vascular health.
• To assess recovery over 72 hours after a COD protocol in collegiate basketball players.

Main Methods:

• A randomized, crossover, double-blind, placebo-controlled study.
• Participants received either BCAAs or placebo (glucose) before and after a COD exercise protocol.
• Measurements included creatine kinase, muscle soreness, neuromuscular performance, and arterial stiffness.

Main Results:

• Muscle damage markers and soreness increased post-exercise, persisting for up to 72 hours.
• Arterial stiffness decreased after exercise in both groups.
• No significant differences in muscle damage, soreness, or performance were observed between BCAAs and placebo groups.

Conclusions:

• BCAAs supplementation does not appear to mitigate muscle damage or soreness after COD sprinting in basketball players.
• The findings do not support the use of BCAAs for enhancing recovery or performance in this context.
