| 摘 要： | 本文报道60名健康男性青年由海拔500m乘机到达海拔3680m,休息7天后,其最大做功量、最大摄氧量(Vo_2max)和最大心率(HRmax)等的变化规律。研究表明,平原人急进高原后,最大做功量由平原11109.1kgf.m降低到3967.7kgf.m,降低64.28％;Vo_2max由平原的2.673L/min降低到2.056L/min,降低23.07％;与最大做功量相比,高原低氧环境对Vo_2max的影响较小,仅以Vo_2max来评价平原人高原劳动能力是不全面的。受试者进入高原后,晨脉升高,HRmax降低,50％最大负荷运动心率升高,表明机体心力储备降低,做功效率降低。

| Abstract: | It is reported the changes of the maximal work capacity, maximal oxygen uptakc(Vo_2max) and maximal heart ratc(IIRmax) of 60 healthy young men used to live in plain cxposurcd to the high altitudc(abovc sea level 3680m) after having rested for 7 days. The results showed that during acute period, their maximal work capacity decreased from 11 109.1 kgf.m to 3967.7 kgf.m and Vo_2max did too from 2.673 L / min to 2.056L / min. Both falling rates were 64.28% and 23.07%, respectively. Therefore the Vo_2max could not appraise overall the people's work capacibility in high altitude because the hypoxia environment had less effects on Vo_2max than work capacibility. After arriving at high altitude, the subjects' basal HR and motcr HR at 50% maximal loading insensity increased, but HRmax towered from 191 b/min to 182 b/min. It was indicated that the heart reserve and work efficiency decreased. |
