目的：探讨补液对热湿环境下运动机体热调节反应和体液调节激素的影响。方法：采用随机对照2×2交叉试验设计，将试验对象随机分为热湿环境运动对照组和热湿环境运动补液组。两组试验对象分别进行一次33℃、80％RH热湿环境下的40min、70％运动强度的热负荷运动，其中补液组运动前和运动中进行补液，对照组不进行补液干预。热负荷运动前后测试试验对象热应激生理学指标及体液调节激素ALD、AVP和ANP水平，以观察两组试验对象测试指标在热负荷运动前后的变化。结果：热负荷运动后，对照组Tc非常显著性升高、HR非常显著性升高，补液组Tc非常显著性升高、HR非常显著性升高；热负荷运动后两组间的Tc、HR、SL、SR未见显著性差异。与对照组相比，补液组热负荷运动时间显著性升高、生理热应力指数未见显著性差异。热负荷运动后补液组和对照组的Na^＋，K^＋，Cl^-均未见显著性差异，但总体上表现为补液组Na^＋和Cl^-水平要高于对照组。与运动前相比，对照组运动后的ALD非常显著性升高、AVP显著性升高、ANP显著性降低；补液组运动后的ALD非常显著性升高、AVP非常显著性升高、ANP非常显著性降低；两组运动后ALD、AVP、ANP均无显著性差异。结论：热湿环境对运动机体的热调节反应和体液调节激素产生明显的影响，补液延长了机体热湿环境下的运动时间，提高了机体在热湿环境下的运动能力。
目的：探討補液對熱濕環境下運動機體熱調節反應和體液調節激素的影響。方法：採用隨機對照2×2交扠試驗設計，將試驗對象隨機分為熱濕環境運動對照組和熱濕環境運動補液組。兩組試驗對象分彆進行一次33℃、80％RH熱濕環境下的40min、70％運動彊度的熱負荷運動，其中補液組運動前和運動中進行補液，對照組不進行補液榦預。熱負荷運動前後測試試驗對象熱應激生理學指標及體液調節激素ALD、AVP和ANP水平，以觀察兩組試驗對象測試指標在熱負荷運動前後的變化。結果：熱負荷運動後，對照組Tc非常顯著性升高、HR非常顯著性升高，補液組Tc非常顯著性升高、HR非常顯著性升高；熱負荷運動後兩組間的Tc、HR、SL、SR未見顯著性差異。與對照組相比，補液組熱負荷運動時間顯著性升高、生理熱應力指數未見顯著性差異。熱負荷運動後補液組和對照組的Na^＋，K^＋，Cl^-均未見顯著性差異，但總體上錶現為補液組Na^＋和Cl^-水平要高于對照組。與運動前相比，對照組運動後的ALD非常顯著性升高、AVP顯著性升高、ANP顯著性降低；補液組運動後的ALD非常顯著性升高、AVP非常顯著性升高、ANP非常顯著性降低；兩組運動後ALD、AVP、ANP均無顯著性差異。結論：熱濕環境對運動機體的熱調節反應和體液調節激素產生明顯的影響，補液延長瞭機體熱濕環境下的運動時間，提高瞭機體在熱濕環境下的運動能力。

The purpose of this paper was to observe the effect of liquid supplement on thermoregulatory responses and fluid regulation hormones of athletes in humid heat environment. Using random control trial of 2 ×2 cross design, the experimental subjects were randomly divided into 2 groups： control group （TC） and liquid supplement group （TB）. TC group and TB group exercised at 70% intensity for 40min in 33℃, under 80%RH heat environment. During heat load exercise, TB had liquid supplement, and TC didnot have liquid supplement. The indexes of thermoregulatory response ALD, AVP and ANP were measured before and after heat load exercise. It could be seen that after heat load exercise, TC group showed significant increase in core temperature and heart rate, and TB group showed significant increase in core temperature and heart rate. Compared with the TC group, TB group exercise time was high, and physiological heat strain index had no significant difference. After heat load exercise, there were not significant differences in Na^＋ , K^＋ , Cl^- between TB group and TC group. After heat load exercise, TC group and TB group showed significant increase in ALD and in AVP, while significant decrease in ANP. There were not significant difference in ALD, AVP, ANP between TB group and TC group. It could be concluded that heat humid environment had obvious effects on body thermoregu｜atory responses and fluid regulation hormones in exercise. Liquid supplement prolonged the athletes＇ exercise time in heat humid environment, which improved athletes＇ sport ability in heat humid environment.
