| 摘 要： | 目的:研究自然高温环境下5 km越野跑对红细胞MDA含量和SOD活性变化,了解自然高温环境下5 km越野跑对红细胞造成的影响.方法:抽取学员18名,随机分为室温组、高温组.室温组在室温28℃.湿度50%的环境下进行5 km越野跑;高温组在地面温度为40℃的环境下进行5 km越野跑.在运动前、运动后即刻、运动后3 h,抽取5 ml肘静脉血m进行红细胞MDA含量和SOD活性的测量.结果:自然高温环境下进行5 km越野跑后,红细胞MDA含量较安静状态非常显著升高(p<0.01),运动后3 h下降显著下降至安静水平(p<0.05),较对照组无显著性差异(p>0.05).红细胞SOD活性较安静状态时显著下降(p<0.05),运动后3 h也基本恢复活性与安静状态比较无显著性差异(p>0.05).结论:自然高温环境下的5 km越野跑可能使红细胞脂质过氧化作用增强,红细胞氧化刺激损伤增加,氧化应激对红细胞的损伤作用可在运动后3 h消除.红细胞氧化损伤增加可能是自然高温环境中进行5 km越野跑,有氧耐力下降更快的原因之一.自然高温环境下训练更应重视训练后的恢复和抗氧化剂的营养补充.

| Abstract: | Subject: In order to understand the impact of 5 km cross-country run on the red cell in the natural high temperature environment,the changes of red cell MDA concentration and the activity of SOD in natural high temperature environment after 5 km cross-country running are studied.Results: The MDA concentration of red cell was significantly increased(p<0.01);and SOD activity was decreased significantly(p<0.05).Conclusion: the 5 km cross-country run in the natural high temperature environment stimulates body more strongly and causes red cell injury.So this decreased function of red cell may be one reason for the fatigue resulted from 5 km cross-country run in the natural high temperature environments.More attentions must be payed to the rehabilitation and antioxidants nutritional supplements. |
