【摘要】：为研究支链氨基酸(BCAA)、精氨酸(Arg)对运动员运动能力的影响及其机制,建立运动竞赛模型。选取自愿参加试验的职业男性篮球运动员14名,随机分为AA试剂组和PB安慰剂组,AA组按0.17g/kg体重的量补充BCAA和0.04g/kg体重的量补充Arg,PB组补充同样计量的安慰剂。实验进行2d,每天进行2组相同的20个2min运动,组间休息10min,每组最后设置1个20m全力冲刺测试。实验结果显示,AA组队员运动后主观感觉疲劳等级(RPE)值显著低于PB组,第2天20m冲刺AA组队员成绩明显优于PB组。研究结果表明:补充BCAA、Arg复合制剂在模拟篮球比赛中可以提高运动员的短距离冲刺能力,并且可以缓解连续2d运动引起的中枢疲劳。
[Abstract]:In order to study the effect of branched-chain amino acid (BCAA), arginine (Arg) on athletes' athletic ability and its mechanism, a competition model was established. Fourteen male basketball players who volunteered to participate in the experiment were randomly divided into AA reagent group and PB placebo group. The AA group supplemented BCAA and 0.04g/kg weight according to the weight of 0.17g/kg and the Arg,PB group supplemented with the same amount of placebo. The experiment was carried out for 2 days, and 20 2min exercises were performed daily in two groups. The rest time was 10 minutes. Each group was given a 20m full sprint test at the end of the experiment. The results showed that the (RPE) value of the AA group was significantly lower than that of the PB group after exercise, and the score of the 20 m sprint AA group was significantly better than that of the PB group on the second day. The results showed that the supplement of BCAA,Arg compound preparation could improve the sprint ability of athletes in simulated basketball match and relieve the central fatigue caused by continuous exercise for 2 days.
