摘要
目的观察在海拔3700m建立富氧室对人体体力活动时氧耗量的影响。方法:10名受试者在进入富氧室前后分别观察氧耗量(VO2)及氧脉搏(VO2/HR)。结果:心率在100b-170b/min时,富氧室随HR增加而呈线性增加[分别为Y=(0.0165+0.0073)x,r=0.9877,P<0.001;Y=(-0.1629+0.0087)x,r=0.9902,P<0.001]。结论:富氧室在高原能提高心脏作功效率和改善肺功能。
Objective: To investigate the effects of oxygen - enriched room on oxygen consumption (VO2) of human physical exercise at high altitude. Method: The VO2 of ten volunteers and their ratio of V02 to pulse (VO2/HR) were determined before and after they entered die oxygen - enriched room. Result; When the heart rates of these subjects were between 100 and 170 beats per minute( bpm), the level of VO2 had a positive linear correlation with heart rate( HR) . Before they entered the oxygen - enriched room, their VO2 = 0.0165 + 0.0073HR,7 = 0.9877, p < 0.001 . After they did the room, their VO2 = - 0.1629 + 0.0087HR, 7 = 0.9902, p<0.001. Conclusion: The oxygen - enriched room could improve subjects' cardiac and pulmonary function and their work efficacy of physical exercise.
