Abstract:
In order to investigate the effect of combined supplementation of branched-chain amino acids (BCAA) and arginine (Arg) on performance in simulated basketball games on two consecutive days. The 14 male basketballers were randomly divided into AA trial group and PB trial group, AA trial group consumed 0.17 g/kg BCAA and 0.04 g/kg arginine together, the control group added same placebo. The test consecutive two days, it was consisted of 20 identical 2 min blocks, rest for 10 min between groups, and a 20 m all-out sprint was performed at the end of each block. The results showed that the average ratings of perceive exertion throughout the 2 days trial was significantly lower in the AA trial than the PB trial. The sprint time was significantly better in the AA trial.It is indicated that BCAA and Arg supplementation could improve performance in sprints ability on the second consecutive day of simulated basketball games in well-trained athletes by potentially alleviating central fatigue.
