碩士 === 國防大學 === 運籌管理學系 === 106 === The main purpose of this study was to investigate the effect of ambient temperature on physiological parameters such as oxygen consumption, heart rate, skin temperature, microclimate (temperature and humidity) and subjective perception assessment during the simulated march. The subjects recruited 10 marine male officers who were in good health and qualified for performing the annual march training mission, and used experimentation methods to conduct research. The maximum oxygen consumption measurement was performed first, and then two different ambient temperature (22°C and 37.5°C; humidity 70%) were created using a thermostatic chamber; The subjects were asked to carry 20 kg and walking on a treadmill at 5 km/h for 50 minutes to simulate actual marching rules. Subjects' oxygen consumption, heart rate, skin temperature, microclimate and subjective perception assessment were recorded throughout the experiment. The results of the study tell us: when the subjects simulated marching at 37.5°C, their heart rate, skin temperature, microclimate, and subjective perception assessment were a significant increase compared to 22°C, in addition to oxygen consumption. However, the subjects simulated marching at 37.5°C, and their average walking time was 28.95 minutes, which was significantly lower than the 50 minutes prescribed by the marching rules. Therefore, the high temperature really increase the physiological load of the military during marching. This study hopes to provide the suggestions in which the Taiwan army change the methods of the marching, and the rest time and frequency of the marching, when they face the high ambient temperature in future.
