Abstract:

BACKGROUND: Intense competition and frequent competition schedule are the salient features of competitive sports. Especially the ball games usually continue for several days, meanwhile athletes need continuous high-intensity physical demands. Central nervous system plays an important role in the process of fatigue formation, and central fatigue status directly affects the competition results.
OBJECTIVE: To further investigate the effects of branched-chain amino acids (BCAA), arginine and citrulline on central fatigue during sports.
METHODS: The model of high-intensity intermittent sports was established, and 12 male basketball players were randomly divided into trial group (0.17 g/kg BCAA, 0.04 g/kg arginine and 0.04 g/kg citrulline), and control group (same volume of placebo). The sports program was 30-second high-intensity cycle, thrice for 3 cycles and resting for 3-4 minutes between cycles. The motion response time, attention distribution and blood samples were tested before and after exercise.
RESULTS AND CONCLUSION: The motion reaction time and the Q value of attention distribution in the trial group were superior to those in the control group. The blood tryptophan/BCAA ratio was significantly reduced in the trial group, but the NH3 accumulation showed no significant difference between groups. Our study shows that BCAA, arginine and citrulline supplementation can alleviate the central fatigue during high-intensity intermittent sports.
