The sample for this study consisted of 28 Aymara males between the ages of 15 and 43 years. The subjects were rural high-altitude natives who were temporarily working as porters in La Paz, Bolivia (3700 m). Mean VO2max was 46 X 5 ml/kg/min. There was a significant negative relationship between VO2max and age in adult porters . However, there was also a significant positive relationship between maximal work output and age and a significant negative relationship between VO2 during submaximal exercise and age. Relative work intensity (VO2/VO2max) during submaximal exercise did not change significantly with age. Thus, even though VO2max decreased significantly with age, these data suggest that there may not be a substantial decrease with age in the adaptive status of these men. Minimal support was found for the hypothesis that chest size in Andean highlanders influences the effectiveness of the oxygen transport system.
本研究的样本包括28名年龄在15至43岁之间的艾马拉族男性。这些受试者是农村高海拔地区的本地人，他们当时在玻利维亚拉巴斯（海拔3700米）临时充当搬运工。平均最大摄氧量为46×5毫升/千克/分钟。成年搬运工的最大摄氧量与年龄之间存在显著的负相关关系。然而，最大工作输出与年龄之间也存在显著的正相关关系，亚极量运动期间的摄氧量与年龄之间存在显著的负相关关系。亚极量运动期间的相对工作强度（摄氧量/最大摄氧量）并未随年龄显著变化。因此，尽管最大摄氧量随年龄显著下降，但这些数据表明，这些男性的适应状态可能不会随年龄大幅下降。关于安第斯高地人胸部大小影响氧运输系统有效性这一假设，得到的支持极少。
