| 摘 要： | 目的探讨高原富氧运动对机体自由基代谢的影响。方法对海拔 5 380m高原的 1 0名健康青年富氧 2 7.3%前后分别进行踏阶运动 ,检测血中超氧化物歧化酶 (SOD )、谷胱甘肽过氧化物酶 (GSH Px)和丙二醛 (MDA )含量。结果富氧运动较未富氧运动SOD、GSH Px增加 (P <0 .0 5 ,P <0 .0 1 ) ,MDA降低显著 (P <0 .0 1 )。结论富氧对高原运动自由基损伤有明显的抑制作用 ,对于增强有氧氧化途径具有重要作用。

| Abstract: | Objective To study the effect of enriched oxygen on free radical metabolism at high altitude. Method SOD,GSH Px and MDA were measured in 10 health young men after step in a room with or without oxygen enrichment at high altitude of 5 380 m.Result After exercise in the oxygen enriched room,SOD and GSH Px increased significantly while MDA decreased notably (P<0.01) than those after exercise in the room without oxygen enrichment(P<0.05 or P<0.01).Conclusion Enriched oxygen can decrease damage from free radical at high altitude. |
