本文研究了平原人移居海拔3680m后,不同时间体力状况,并与条件相近的藏族世居者进行了比较。研究结果表明,移居者的屏气时间较短,表明其缺氧耐受力低。低氧环境对60m跑和握力等无氧运动项目的影响不大。世居者与平原人相比,Vo_2rmax等指标均低于平原人,表明即使对低氧环境产生习服的人体,也不可能达到平原水平,机体的代偿调节能力是有限的。移居者的Vo_2rmax和HBmax等经过7～15个月的适应,可接近世居者水平。但1000m跑成绩大大低于世居者,可能是两种人群对Vo_2rmax的利用率不同引起。
This paper studies the physical condition of plain people after they have been migrated to 3680m above sea level at different time and compared with the Tibetan settlers with similar conditions. The results show that migrants have a shorter hold-up time, indicating low tolerance to hypoxia. The hypoxic environment has little effect on anaerobic exercise items such as 60m running and grip strength. The index of Vo_2rmax and other indicators were lower than that of the plain people in the home and the plain, indicating that even in the hypoxic environment of the human body, it is impossible to reach the level of plain, the body’s compensatory capacity is limited. The migrants Vo_2rmax and HBmax, after 7 to 15 months of adaptation, can be close to the level of the Habitat. However, the results of 1000m runners were much lower than that of the natives. This may be caused by the different utilization rates of Vo_2rmax in the two populations.
