对拉萨(海拔3658M)16名世居藏族和20名移居汉族健康青年男性的最大O_2摄取,最大运动负荷及其影响因素进行了研究。结果发现在最大努力作功时,藏族的最大O_2摄取量、最大运动负荷量、潮气量、肺通气量及氧脉搏等均大于汉族,而两者心率相同。说明世居藏族具有更好的0_2转运功能。
The maximal O 2 uptake, maximum exercise load and its influencing factors of 16 native Tibetan and 20 migrant healthy young men in Lhasa (3658 M) were studied. The results showed that the maximum O_2 intake, maximum exercise load, tidal volume, pulmonary ventilation and oxygen pulse of Tibetans were all greater than those of Han nationality at maximum effort, and the heart rate was the same between the two. It shows that Tibetan people in the world have better 0_2 translocation function.
