碩士 / 國防大學 / 運籌管理學系 / 107 / In order to ensure that Taiwan’s Army personnel or high-altitude workers and emergency rescuers can maintain their performance in the acute exposure to low-oxygen pressure environment when they are rapidly entering high altitude to perform high altitude and cold weather personnel rescue training or related high altitude operations every year, it is necessary to have an in-depth understanding of the maximum oxygen-consuming aerobic exercise capacity and physiological response in a hypoxic environment.
This study aims to study the effect of hypoxia on the maximum oxygen consumption (VO2max) and physiological response (HR、SPO2、RF、AMS). This research recruited 12 subjects from the National Defense University (6 males and 6 females) that regularly-exercise. Subjects will simulate three different levels of oxygen in a hypoxic chamber at three different altitudes: 0 meters (sea level), 2,000 meters (Taipingshan) and 3,000 meters (Hehuanshan). Each subject will be asked to perform incremental Bruce test in a hypoxic chamber with one of three hypoxic conditions every time. The subject’s VO2 max and the physiological responses will be measured.
The results showed that during the rest period, the resting heart rate in the cabin was significantly greater than that outside the cabin, and the blood oxygen saturation concentration was significantly reduced; during the exercise phase, the heart rate and respiratory rate are the largest due to exercise load, and the blood oxygen saturation concentration is the smallest; finally, during the recovery phase, the blood oxygen concentration and respiratory rate are the first to return to normal, and the heart rate continues to compensate for physiological needs. In this experiment, the exposure time of hypoxia test was short, and the AMS score system showed no peak disease. Therefore, after working or training in a high-altitude environment, the heart rate can be used as an observation indicator for the physiological recovery of the person.
