摘要
目的:探讨富氧水对高原人体运动后自由基代谢的影响。方法:在海拔3700m选择10名已习服半年的健康男性青年,在海拔5380m选择10名已习服2个月的男性青年,均采用口服富氧水前(对照组)后(实验组)的自身对比运动负荷双盲实验。实验组口服富氧水,对照组口服5%葡萄糖注射液,每次500mL,一日2次,连续服用3天。运动结束后检测血中超氧化物歧化酶(SOD)、丙二醛(MDA)、一氧化氮(NO)及其合酶(NOS)在口服富氧水前后的变化。结果:海拔3700m和5380m负荷运动后,实验组SOD、NO和NOS增高,差别有非常显著性(P<0.01);MDA降低,差别有显著性(P<0.05或0.01)。结论:富氧水可增加体内氧含量,对低氧造成的自由基代谢失衡有调节作用。
Objective：To study the effects of oxidizing water on free radical of human exercise at high al- titude. Methods： 10 healthy male youths who acclimatized for half year in 3 700m altitudes and 10 healthy male youths who acclimatized for two months in 5 380m altitudes were selected in this study. The test was double-blind and divided into the test group in which oxidizing water was given after exercise and the control group in which 5% glucose injection was given before exercise. The level of SOD, MDA, NO and NOS were measured when exercise ended. Results： Compared with control group, the level of SOD, NO, NOS were increased （P〈0. 01）and the level of MDA was lower （P〈0. 05 or 0. 01）in the test group whether at 3 700m or 5 380m. Conclusions： The oxidizing water could increase oxygen content inside the body, and could regulate the imbalance free radical metabolism-hypoxia induced.
