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 ［φ(O2)=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. |
