摘　　要：目的:观察急性抗阻运动及不同比例糖和蛋白营养干预对男子力量项目运动员尿雄激素变化的影响。方法:18名男子力量项目(拳击、健美)运动员,分为糖加高蛋白补充组(HP组,糖和蛋白比例为3:1)、糖加低蛋白补充组(LP组,糖和蛋白补充比例为6:1)及纯糖补充对照组(C组),所有受试者进行相同的抗阻运动,先进行4组70%1RM深蹲动作,每组8次,组间休息60 s,第4组完成后休息90 s;随后完成4组50%1RM深蹲动作,第1、2组重复8次,后两组重复至不能完成动作为止,组间休息60 s,第4组完成后休息150 s;接下来完成4组70%1RM卧推动作,组间休息60 s,第4组完成后休息90 s;最后完成4组50%1RM卧推动作,第1、2组重复8次,后两组重复至不能完成动作为止,组间休息60 s。采用气相质谱色谱仪(GC-MS)测定运动前、运动后即刻及次日晨尿雄激素。结果:急性运动后即刻各组尿本胆烷醇酮及雄酮比运动前显著升高(P<0.05),组间无差异。运动后次日晨,HP组和LP组尿5α-雄烷二醇和5β-雄烷二醇比运动前显著升高(P<0.05),组间比较HP组5α-雄烷二醇和5β-雄烷二醇显著高于LP、C组(P<0.05)。结论:急性抗阻运动及糖和蛋白营养干预能加速男子力量项目运动员性腺雄激素和肾上腺雄激素转化和代谢,促进睾酮向双氢睾酮转化,有利于脂肪分解和糖酵解,促进机体运动后疲劳恢复。Objective To investigate the effects of carbohydrate-protein supp｜ementations with differ- ent ratios on the body recovery process after acute resistance training and urine androgen metabolism of male boxers and bodybui｜ders. Methods Eighteen male boxers and bodybuilders were supplied with high-protein and low-carbohydrate（group HP, carbohydrate：protein = 3：1 ）,low-protein and high-carbo- hydrate（group LP,carbohydrate：protein = 6：1 ） and carbohydrate only（group C）. All subjects completed4 sets of S-repetition squats at 70% of 1-RM with 60-second interval. There was 150-second interval after the fourth set. The last two sets were carried out until the subjects were exhausted. Then,4 sets of bench press at 70% of 1-RM were followed with 60-second interval,and 90-second interval after the last set. Again,4 sets of bench press at 50% of 1-RM were followed until the actions of the last two sets could not be repeated. Gas chromatography mass spectrometry （GC-MS） was used to observe urine an- drogen before exercise,and immediately and in the next morning after exercise. Results Etiocholanalone and androsterone in each group increased significantly （P 〈 0.05） immediately after acute resistance ex- ercise, but there was no difference among the 3 groups. 5α-androstanediol and 5β-androstanediol in- creased significantly （P 〈 0.05） in groups HP and LP in the next morning after acute resistance exer- cise, and they were significantly higher in group HP than that in groups LP and C （P 〈 0.05）. Conclu- sions Carbohydrate-protein supplementation during acute resistance training can accelerate the transfor- mation and metabolism of gonad androgen and adrenal androgen, promote testosterone transforming to hydrotestosterone, and thus benefit the recovery process after acute resistance exercise.
