摘　　要：目的探讨拉萨地区人群血氧饱和度及运动前后的差异。方法随机选取藏族人群和平原移居者(2年以上)各50名测定血氧饱和度,并对70名驻藏战士5公里越野运动前后的血氧饱和度进行测定,将三组人群的检测结果进行比较分析。结果高原世居者和平原移居者静息状态下血氧饱和度没有显著性差异,平原移居者运动后血氧饱和度下降明显,与运动时间之间存在着正相关。结论高原世居者比平原移居者具有更强的活动能力,平原移居者在高海拔地区进行重体力活动时氧经肺的弥散受到限制。Objective To discuss the blood oxygen saturation of the people in Lasa and the difference of blood oxygen saturation before and after exercise. Methods 50 Tibetans and 50 plain migrants from high altitude （ over 2 years ） were randomly selected and their blood oxygen saturations were detected; the blood oxygen saturations of 70 resident soldiers in Tibet were detected before and after the 5km cross - country running; the detection results of the people in the 3 groups were compared and analyzed. Result There existed no significant difference of blood oxygen saturation between altitude residents and plain migrants in the resting state; the blood oxygen saturation of plain migrants after exercise decreased obviously, which was in positive correlation with the time length of exercise. Conclusions The plateau habitants are of stronger activity ability than plain migrants ; the oxygen dispersion via lungs of plain migrants is limited when they undergo heavy physical activity at high altitude.
