Branched-chain Amino Acids Aid Athletic Performance
 
Published Wednesday, February 1, 2006

CHIBA, Japan--Branched-chain amino acids appear to enhance training efficiency in athletes, according to Japanese researchers (J Nutr, 136:538S-43S, 2006). A combination of branched-chain amino acids, arginine and glutamine was studied for its impact on muscle function, fatigue and recovery in exercising athletes. In a dose-response study, administration of 6.6 g/d for 30 days increased indices of blood oxygen-carrying capacity and decreased indices of muscle damage. When the amino acid mixture (7.2 g/d) was given to elite rugby players for 90 days during training, the oxygen-carrying capacity of the blood was improved. The researchers concluded the amino acid supplement improved athletic training by improving muscle integrity and blood oxygen-carrying capacity.
