摘　　要：背景:赛事紧密、竞争激烈是目前竞技体育运动的显著特征。尤其是球类项目,比赛通常连续多天进行,运动员需要持续多天的高强度对抗,中枢神经系统在机体疲劳的形成过程中起着至关重要的作用,运动员中枢疲劳状态直接影响着竞赛成绩。目的:进一步研究支链氨基酸、精氨酸和瓜氨酸对运动员运动性中枢疲劳的影响及其机制。方法:建立高强度间歇运动模型,选取自愿参加试验的职业男性篮球运动员12名,随机分为补剂添加组和安慰剂组,补剂添加组按0.17 g/kg剂量补充支链氨基酸、0.04 g/kg剂量补充精氨酸和0.04 g/kg剂量补充瓜氨酸;安慰剂组补充同样计量的葡萄糖淀粉胶囊安慰剂。运动方案为3组3次30 s的全力功率自行车蹬踏运动,组间休息3.0-4.0 min。于测试前后进行运动反应时、注意分配测定和静脉穿刺抽血样。结果与结论:(1)相对安慰剂组,补剂添加组队员运动反应时明显快于安慰剂组,注意分配Q值优于安慰剂组;(2)补剂添加组队员血液色氨酸/支链氨基酸值显著降低,但NH3积累与安慰剂组相比无显著性差异;(3)研究认为补充支链氨基酸、精氨酸和瓜氨酸复合制剂能够缓解高强度间歇运动引起的枢神经疲劳(注意分配值降低,运动反应时增长)。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.
