Effect Of Branched-Chain Amino Acid Supplementation On Recovery Of Performance And Muscle Damage, & Autophagy And Heat Shock Protein Response, Trisha Vandusseldorp

Health, Exercise, and Sports Sciences ETDs

Purpose: To investigate: 1) if branched-chain amino acid supplementation (BCAA) enhances recovery from acute, eccentric resistance exercise as measured by indirect markers of muscle damage, and 2) the impact of acute, eccentric resistance exercise on markers of autophagy and heat shock protein during recovery. Methods: Twenty resistance-trained males were randomly assigned to eight days of BCAA or PLCB and adhered to a diet consisting of 1.2 g/kg/d protein. On day five, all subjects completed 10x8 eccentric squats at 70% one repetition maximum (1RM), followed by 5x20 split jumps. Plasma creatine kinase (CK), erythrocyte glutathione, vertical jump (VJ), maximal voluntary isometric …
