Get The Winning Edge With Branch-chain amino acids
Branched-chain amino acid leucine, isoleucine and valinesupplements are extremely popular a help and have been found to boost protein synthesis during and after heavy exercise and also help improve physical performance.
A study reported in Amino Acids 1993;4:255-266 found that athletes supplementing with these BCAA demonstrated a significant improvement in exercise performance. Another study found that BCAA supplementation can reduce muscle breakdown in athletes (Effect of Branch-Chain Amino Acids Supplementation on the Exercise-Induced Change in Aromatic Amino Acid Concentration in Human Muscle, Blomstrand, E et al, ACTA Physiol Scand, 1992;146:293-298)
Older athletes can also benefit from BCAA supplementation. Studies have found that in older adults supplemented with 4g of leucine per meal improved muscle protein synthesis(Casperson SL et al.: L-Leucine supplementation chronically improves muscle protein synthesis in older adults consuming the RDA for Protein; Clin Nutr. 2012 Feb 20)
