摘　　要：目的确定支链氨基酸是否能够降低运动造成的延迟性肌肉疼痛(DOMS)。方法采用双盲交叉实验设计。选取40名大学生(20女,20男)随机分成支链氨基酸组(n=20)和安慰剂组(n=20)。受试者进行200m自重蛙跳的训练用于引起DOMS,并且在服用支链氨基酸或安慰剂的同时,每隔24h,连续3天,对肌肉疼痛程度进行分级。在3周恢复期后,受试者再次进行支链氨基酸或安慰剂的干预实验,重复同样的运动程序,并在接下来的3天里进行肌肉疼痛的分级。结果与结论运动后24h,在女性受试者中,支链氨基酸补充使得DOMS降低与安慰剂组相比有显著的差异(p=0.015)。然而,对于女性受试者和男女受试者整体分析时则没有显著性差异。这种性别的差异可能与男女受试者单位体重补充支链氨基酸的剂量差异和女性雌激素对BCODH激酶代谢的影响有关。Objective To determine whether the BCAA can reduce exercise-induced delayed onset muscle soreness(DOMS).Methods Adopting double blind experiment design,40 subjects(20 females,20 males)were randomly divided into BCAA(n=20)or placebo(n=20)groups.Subjects be asked to a 200m leapfrog exercise to induce DOMS and rated their muscle soreness every 24 hours for three days following exercise while sustaining to take the BCAA or placebo.after a three-week recovery period,The subjects of BCAA or placebo intervention experiment and repeated the same exercise and DOMS rating protocol.Results and Conclusion For female subjects(BCAA)resulted in a significant decrease in DOMS versus placebo at 24 hours following exercise(p=0.015).No significant effect in male subjects nor when male and female results were analyzed together.This gender difference may be associated with the dose of male and female subjects unit weight added BCAA and the regulation of branched-chain amino acid catabolism The influence of estrogen to BCODH kinase in female.
