目的：观察10天热适应过程中机体热调节反应及HSP70变化，探讨运动员运动训练和比赛实践中热适应的有效建立。方法：以8名中长跑男性运动员为受试对象，在温度为33℃、湿度为80％RH环境条件下，进行连续10天60min、40％抛max强度的热适应运动，观察第2天、6天和10天机体热调节反应及HsP70变化。结果：中长跑运动员10天热适应过程中的体核温度、心率、主观感觉疲劳程度、出汗量、出汗率、汗液电解质离子和HSP70出现一些明显的变化，主要表现为热适应过程中运动后体核温度、心率逐渐下降，运动排汗能力增强，汗液电解质离子浓度显著下降（P〈0．01），运动后HSP70水平显著升高（P〈0．01）。结论：热适应过程中机体出现体核温度下降、心率下降、排汗能力增强和HSP70水平升高等热适应性变化，提示中长跑运动员经过10天热适应运动后，机体已经有效地建立了热适应。

Objective：To investigate changes of thermoregulatory responses and hsp70 in 10-day heat acclimation of middle-long-distance runners, and explore how to establish heat acclimation in practice of training and competing. Methods： Taking 8 middle-long-distance runners as the research objects. In a hot environment（33 ℃, 80% relative humidity）, participants were asked to cycle at 40% of their VO2 max workload for 60 minutes during 10 days, and the indexes of thermoregulatory responses were measures on 2,6,10 days. Results ： There were some regular and adaptable changes of body core temperature, heat rate, ratings of perceived exertion, sweat loss, sweat rate and sweat ion of middle-long-distance runners in 10-day heat acclimation. The body core temperature, heat rate and sweat ion were decreased. The sweat rate was increased. The serum concentration of hsp70 was increased. Conclusion： The adaptable changes of body core temperature, heat rate, sweating, hsp70 in 10-day heat acclimation suggested that the heat acclimation of middle-long-distance runners were successfully came into being.
