Abstract：Objective To study the changes of physiological indexes of subjects under high intensity military training despite high risk of heatstroke, and to provide reference for heatstroke prevention. Methods Subjects selected from East China(293 people), South China(208 people), and Central China(601 people)were subjected to 5, 10 km, and 20 km running under a heat index of ≥40. Fifty subjects were selected from each region for measurement of their heart rate, core temperature and body weight before training and after training. Measurement was taken in case of discomfort. Heatstroke prevention education was given before the experiment, and subjects drank 400 ml water. Results The average heart rate of the subjects was >170 times per minute during training, which indicated a high training intensity. When the heat index reached 40, the incidence of heatstroke and signs of heatstroke was 0.91%. There was significant difference in body weight changes and core temperature changes after training(P<0.05). The core temperature of the subjects who experienced heatstroke was >38.5 ℃, their heart rate recovery was slow, and they had predisposition. Conclusion Effective measures of prevention can reduce the incidence of heatstroke.Physical discomfort is the cause of heat stroke in hot seasons.
