| 摘 要： | 为了观察模拟高住低练对人体红细胞中丙二醛(MDA)、超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)的影响,及在模拟高原训练后有氧运动能力是否提高.将男大学生13名随机分成对照组和模拟高住低练组,从事相同身体活动,模拟高住低练组每天低氧环境睡眠8 hφ(O2)=14%],连续4周.两组均在低氧训练开始前、结束后进行Bruce方案的力竭运动,并在安静和运动后取血测试MDA、SOD、GSH-Px.结果表明:高住低练组红细胞SOD、GSH-Px活性在安静时和力竭运动后都明显提高,MDA没有变化,定量负荷后心率和血乳酸降低.结论:模拟高住低练有助于增强红细胞抗氧化能力,改善有氧运动能力.

| Abstract: | Objective: To observe the effect of simulated HiLo training (living high and training low) on MDA, SOD and GSH-Px in erythrocyte of a human body,and to find out whether aerobic sports capacity is enhanced. Method: 13 male college students were randomly divided into a control group and a simulated HiLo training group,and both groups engaged in the same physical activities; the simulated HiLo training group slept 8 hours a day under hypoxia environment (O_2)=14%] for 4 weeks consecutively; both groups carried out an exhaustion exercise in Bruce program before and after hypoxia training, and were blood drawn for MDA,SOD and GSH-Px tests at calm and after the exercise. Results: In respect to the simulated HiLo training group, the activities of SOD and GSH-Px in erythrocyte at calm and after the exhaustion exercise were obviously enhanced,while MDA remained unchanged,and the heart rate and lactic acid level after rationed load were lowered. Conclusion: The simulated HiLo training group is conductive to enhancing the ability of erythrocyte to resist oxidation, as well as enhancing and improving aerobic sports capacity. |
