藏族较汉族对高原低氧有较高的适应性已得到公认，这种高度适应性是高原环境所致，还是遗传基因特点不同仍不清楚。目前研究发现，出生在高原的藏族较汉族有更大的肺活量及最大通气量，在运动时氧摄取能力、最大心输出量及脑供血能力均强于汉族［１，２］。出生高原的藏族...
The higher adaptability of Tibetans to plateau hypoxia than the Han nationality has been recognized. Whether this high degree of adaptation is caused by the plateau environment or the genetic characteristics is still unclear. The present study found that Tibetans born in the plateau had greater lung capacity and maximum ventilation than Han people, and their oxygen uptake capacity, maximum cardiac output and cerebral blood supply were stronger than Han during exercise [1,2]. Tibetan plateau born ...
