本文采用踏阶法(阶梯高度0.4m,踏阶速度22.5step/min)测定了40名平原男性青年长期暴露海拔3700m高原过程中心功能适应指数的改变,并与海拔3700m高原移居一年和世居男性青年水平进行了比较。结果提示:平原人移居海拔3600m高原3个月后心脏功能恢复到平原水平和同于世居者水平,心功能适应指数可用于急性暴露高原人体心脏功能和劳动能力的评价。
In this paper, 40 steppe young adults were measured by step method (step height 0.4m, step speed 22.5step / min) to measure the changes of central functional adaptation index of long-term exposed 3700m altitude plateau, Living male youth level were compared. The results suggest that plain people migrate to altitude 3600m plateau 3 months after the heart function returned to the level of the plain and the same as the native level, cardiac function index can be used for acute exposure plateau human heart function and ability to assess.
