热应激对运动机体的影响

Effect of heat stress on body movement

在热环境下运动时,过度热应激会对运动机体造成一系列的生理、心理影响:脑工作能力下降,电解质、微量元素大量流失,血液中激素水平发生改变,心血管功能发生障碍,肌糖原利用率下降,脂质过氧化严重导致机体抗氧化能力下降,热休克蛋白HSP70合成改变以及不良情绪增多等。通过科学的补液和适当的热适应,可使机体保持体热和血容量的平衡,使机体保持较高的竞技能力。

This paper reviews the impact of thermal environment movement, heat stress on the body caused by a series of physiological movement. The psychological impact of the declining work： brain, electrolyte substantial loss of trace dements in the blood hormone level changes in cardiovascular function of obstacles muscle glycogen utilization decreased lipid peroxidation led to a serious decline in the antioxidant ability of the body, and reduced the heat shock protein HSP70.
