The Acute Effects Different Quantities of Branched-Chain Amino AcidsHave On Recovery of Muscle Function

Harry F Dorrell,Thomas I Gee

The purpose of the study was to investigate the acute effects of two different quantities of branched-chain amino acids (BCAA) on the recovery of muscle function following high-intensity resistance training in trained individuals. Five resistance-trained males were recruited and performed baseline assessments of, countermovement (CMJ) and squat jump (SJ), peak (PP) and mean (MP) power (6s Cycle Sprint) and perceived muscle soreness (RMS). In a counterbalanced, single-blind fashion, participants were provided with either, placebo or 6 g or 18 g BCAA 20 min prior to, and immediately after completion of a high-intensity strength session (ST). At 24 h post ST, all assessments were completed under all three experimental conditions. Following ST, there were significant decrements in all measures of muscle function across conditions when compared to baseline values (P
