摘要
目的:探讨高温不同湿度环境下运动对最大摄氧量、电解质及其调节激素的影响。方法:20名男性受试者随机分成对照组和运动组,实验分4次完成,测定运动组最大摄氧量值,运动和对照组测试后的尿电解质、血清血管紧张素Ⅱ和醛固酮浓度。结果:运动组33℃80%相对湿度时的最大摄氧量值明显低于其他湿度。湿度对血管紧张素Ⅱ和醛固酮浓度都有明显的影响(P<0.01);运动能明显升高血管紧张素Ⅱ和醛固酮浓度(P<0.01)。结论:1)高温高湿环境(33℃80%RH)中机体运动能力下降。2)运动促进血管紧张素Ⅱ和醛固酮的释放。3)高温时不同湿度对血管紧张素Ⅱ有明显影响。
Objective： The purpose of this study was to discuss the effect of acute exercise in hot and different relative humidity environment on electrolyte and serum angiotensionⅡ（AngⅡ） and aldosterone.Methods： Twenty male subjects were randomly divided into control group and exercise group.After the experiment,the VO2max of the exercise,electrolyte,serum ang II and aldosterone concentration.Results：After exercise,exercise group VO2max at 80%RH was lower than other RH.AngⅡ and aldosterone have obvious changes in different relative humidity（P0.01）;Exercise promote serum AngⅡ and aldosterone significantly（P0.01）.Conclusion： 1）Hot and humid environment inhibit exercise ability.2）Exercises promote serum AngⅡ and aldosterone concentration.3）Different humid in hot environment has significant effect in the serum AngⅡ concentration.
