Eight members of the American Women's Himalayan Expedition, ranging in age from 20-49, performed maximal exercise on a treadmill under normoxic and acute hypoxic (12.58% O2) conditions. Normoxic values for VO2 max were above average for all subjects and did not decline with age. The mean decrease in VO2 max (26.7%) during hypoxia was equivalent to that reported for younger males, which suggests that age was not a factor in response to hypoxia. Maximal heart rate, respiratory exchange ratio, oxygen pulse, and walk time were lower in hypoxia while ventilatory equivalent and blood lactate were higher. VEmax BTPS, was the same under both conditions. The combination of laboratory results and field observations by the Expedition physician suggest that women are capable of performing hard work at high altitude if they are in good condition and properly acclimatized.
美国女子喜马拉雅探险队的八名成员，年龄在20至49岁之间，在常氧和急性低氧（氧气含量12.58%）条件下在跑步机上进行了最大运动。所有受试者的常氧最大摄氧量值均高于平均水平，且不随年龄下降。低氧期间最大摄氧量的平均下降幅度（26.7%）与年轻男性的报告值相当，这表明年龄不是对低氧反应的一个因素。低氧时最大心率、呼吸交换率、氧脉搏和步行时间较低，而通气当量和血乳酸较高。两种条件下的最大每分通气量（BTPS）相同。探险队医生的实验室结果和实地观察结果表明，如果女性身体状况良好且适应得当，她们有能力在高海拔地区进行高强度工作。
