日训练时长对热湿环境下人员热适应性的影响

Influence of daily training duration on personnel thermal adaptation in hot and humid environment

以12名健康男性大学生为样本,在热湿环境舱内通过跑步机进行热习服训练,研究不同日运动时长下人体进行热习服训练的适应性过程,根据实验结果判断不同日训练时长下热习服形成的程度并总结相应的生理反应规律。通过配对样本t检验方法分析热习服训练的效果,利用测得的实验数据,探寻与运动时间有关的评价人体热习服训练效果的最佳训练方式。结果表明:热习服训练会影响人体的生理参数,从而有效改善高温高湿环境下人员对环境的热适应性;不同热习服日训练时长对人体直肠温度的影响较心率更为显著;单次热暴露时间越长,热习服训练效果越显著。

Selecting 12 healthy male college students as volunteers, carries out heat acclimation training through walking on the treadmills in a hot and humid environment cabin, studies the adaptive process of the human body to different time-related heat acclimation trainings and summarizes the corresponding physiological response law. Analyses the effect of heat acclimation training by the paired sample t-test method. Explores the best training method for evaluating the effect of human heat acclimation training related to exercise time using the measured experimental data. The results show that the heat acclimation training can affect the physiological parameters of human body, so as to effectively improve the thermal adaptability of personnel to the high temperature and humidity environment. The effect of different daily-heat acclimation training durations on rectal temperature is more significant than that of heart rate. The longer the time of single heat exposure, the more significant the effect of heat acclimation training.
