高温高湿环境下补液对有氧耐力的影响

Effect of Fluid Replacement on Aerobic Endurance in High Temperature and High Humidity Environment

目的:研究高温高湿环境下运动时补液对有氧耐力的影响。方法:随机选取吉林体育学院运动训练专业学生30名,年龄、身高、体重、肺活量、VO_(2max)等指标均无差异,分为常温常湿组、高温高湿组、高温高湿补液组,测试实验过程中的心率(HR)、肌氧含量的变化、运动持续的时间以及恢复时间。结果 :对高温高湿环境下运动进行补液干预,发现与高温高湿组相比,补液组体温、HR相对较低,肌氧饱和度下降幅度小,运动持续时间延长、恢复时间缩短。补液可以提高高温高湿环境下有氧运动的能力。

To study the effect of fluid replacement on aerobic endurance during exercise in high temperature and high humidity environment. Method： 30 athletes from Jilin Institute of Physical Education were randomly selected. There was no difference between the indexes of age, height, weight, vital capacity and VO2mx. The subjects were divided into normal temperature and normal humidity group, high temperature and high humidity group, high temperature and high humidity flu- id replacement group. HR, muscle oxygen content changes and the duration of exercise and recovery time were measured in the process of the experiment. Result： Compared with the high temperature and high humidity group, the body temperature and heart rate of the fluid replacement group were lower. The decrease of muscle oxygen saturation was lower. The duration of exercise was prolonged, while the recovery time was shortened. So fluid replacement can improve the ability of aerobic exercise in high temperature and high humidity environment.
