Branched-chain amino acids (BCAAs) are essential nutrients that play a significant role in muscle metabolism and recovery. They are commonly used as supplements by athletes and individuals undergoing strength training to enhance muscle performance, reduce muscle soreness, and improve recovery. This synthesis aims to evaluate the effectiveness of BCAA supplementation in improving strength training results based on recent research findings.
Improvement in Muscle Strength and Function:
Enhanced Recovery and Reduced Muscle Damage:
Reduction in Delayed-Onset Muscle Soreness (DOMS):
Optimal Dosage and Timing:
Mixed Results on Muscle Hypertrophy:
Overall, BCAA supplementation appears to be beneficial for improving muscle strength, reducing muscle damage, and enhancing recovery following strength training. The optimal benefits are observed when BCAAs are consumed before and after exercise, with a dosage of 2-10 g per day. While the impact on muscle hypertrophy remains inconclusive, BCAAs are effective in reducing delayed-onset muscle soreness and maintaining muscle function, particularly in trained individuals and those undergoing rehabilitation.
