【摘要】:目的:探讨热习服对湿热环境下运动机体体液调节激素ALD、AVP、ANP、NE及Hsp70的影响。方法:16名中长跑运动员随机分为热习服组(HA)和对照组(HC),每组各8人;HA组先进行10天的热习服方案,使机体产生热习服,然后进行一次33℃、80%RH湿热环境下的40min、70%VO2max运动强度的热负荷运动;HC组不经过热习服阶段,直接进行一次同于热习服组的热负荷运动。热负荷运动前后测试实验对象的热应激的生理学指标及体液调节激素ALD、AVP、ANP、NE及Hsp70的水平,观察两组实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,HA组和HC组核心温度和心率均非常显著性升高(P0.01),出汗率无显著变化;HA组热负荷运动后的核心温度和心率水平比对照组低、出汗率水平比对照组高,但两组间差异无统计学意义。与运动前相比,HA组和HC组热负荷运动后红细胞压积非常显著性升高(P0.01)。与运动前相比,HA组和HC组运动后ALD和NE非常显著性升高(P0.01),AVP显著性升高(P0.05),ANP显著性降低(P0.05),Hsp70非常显著性升高(P0.01),但组间检验均未见显著性差异(P0.05)。结论:体液调节激素对维护热负荷运动过程中的机体水盐代谢和平衡发挥着重要作用;热习服一定程度上降低了机体对热负荷运动应激的生理生化热调节反应,提高了机体适应运动热环境的能力。
