我们对28名自愿受试者,年龄在20.3±0.7在海拔760米,Po2=147Torr进行了对外加负荷因素——模拟海拔7500米的耐受能力(Po2=58Torr)运动(PWC170试验)和吸入常氧高二氧化碳的研究。在海拔3,600米处(Po2为103Torr,天山),根据他们对模拟低氧的耐受程度,分别于在高原适应第3天和第20天测定了他们的运动能力.根据有效清醒时间的值将受试者分为3个组,第一组为低耐受组,有效清醒时间为8.0±1.2分钟,13例.第二组为中等耐受组为13.5±0.9分钟,8例,第三组为高耐受组为39.2±1.5分钟,7例.
We tested 28 volunteers aged 20.3 ± 0.7 at an altitude of 760 meters and Po2 = 147 Torr under the applied load factor of 7500 m (PoC = 58 Torr) (PWC170 test) and inhaled Oxygen high carbon dioxide research. At 3,600 meters above sea level (103 Torr, Po2, Tianshan), their ability to exercise was measured respectively at day 3 and day 20 of altitude adaptation, based on their tolerance to simulated hypoxia. Based on the value of effective wakefulness time Subjects were divided into three groups, the first group of low-tolerance group, the effective awake time was 8.0 ± 1.2 minutes, 13 cases.The second group was 13.5 ± 0.9 minutes of moderate tolerance group, 8 cases, the third group For the high-tolerance group, 39.2 ± 1.5 minutes and 7 cases.
