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

 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.
