本研究从急性低氧对移居海平面后藏族的体力活动能力的影响来探索藏族的高原低氧适应机制。结果揭示藏族的最大体力负荷强度没有显著下降，最大氧耗和氧脉搏也没有明显变化，动脉血氧饱和度明显高于汉族，这更显示藏族对高原低氧适应机制有独特之处。推测可能是藏族在氧的摄取、传递和释放过程比汉族更有利于对高原低氧环境的适应。
In this study, we explored Tibetan plateau hypoxia adaptation mechanism from the impact of acute hypoxia on Tibetan people’s physical activity ability after moving to sea level. The results revealed that the maximum physical load intensity of Tibetans did not significantly decrease, the maximum oxygen consumption and oxygen pulse did not change significantly, and arterial oxygen saturation was significantly higher than that of Han people. This shows that Tibetans are unique to the adaptation mechanism of plateau hypoxia. It is speculated that Tibet may be more suitable for adaptation to the hypoxic environment in the plateau than oxygenation in the uptake, transmission and release of the Tibetan Plateau.
