The aim of this study was to examine the efficacy glutamine ingestion on basketball players power performance. Forty men of a university basketball team (20.4 ± 1.6 years; height: 188.6 ± 8.7 cm; body mass: 76.5 ± 7.9 kg) volunteered for this study. Subjects participated in four trials, each consisting of a 40-min basketball game with controlled time-outs for rehydration. During the FS (first trial), subjects were not allowed to rehydrate, and the total weight lost during the contest was used to determine fluid replenishment. During one trial subjects consumed only W (water), while during the other two trials subjects consumed the glutamine supplement mixed in water using either a low dose (1 g per 500 ml) (G1) or high dose (2 g per 500 ml) (G2). A 14.6% difference in basketball shooting performance was shown between FS and G1, and there was significant difference between FS and G1 for shooting performance at P < 0.05. There was no significant difference in vertical jump power during any trial. Glutamine had significant effects on the reaction time at 5% probability level. It concluded that the test should be performed by different doses of the glutamine on the different sport team of men and women.
