During the French 1980 Mount Pabil (7,102 m) Expedition, a study was made of four altitude-acclimatised climbers (age 36.5 +/- 3.6 years; VO2max 50.5 +/- 3.1 ml X kg-1). Intake of various nutrients, body weight, skinfold thicknesses as indices of body composition, and water and nitrogen balances, were recorded before, and during high altitude exposure, and again after the return to low altitude. There was a significant (35-57%) reduction in total caloric intake at high altitude. Body weight decreased progressively, mainly due to a reduction in body fat. The subjects apparently remained in water balance, while the nitrogen balance was always negative during high altitude exposure. The significant nutritional alterations were mainly observed above 6,000 m. They are discussed with respect to changes in feeding patterns and in hormonal status of the climbers accompanying hypoxia and other stressors proper to high altitude.
在1980年法国帕比尔峰（7102米）探险期间，对四名适应了高原环境的登山者（年龄36.5±3.6岁；最大摄氧量50.5±3.1毫升·千克⁻¹）进行了一项研究。记录了在高海拔暴露前、期间以及返回低海拔后各种营养素的摄入量、体重、作为身体成分指标的皮褶厚度以及水和氮平衡情况。在高海拔地区，总热量摄入显著减少（35%-57%）。体重逐渐下降，主要是由于身体脂肪减少。受试者显然保持了水平衡，而在高海拔暴露期间氮平衡始终为负。显著的营养变化主要出现在6000米以上。结合登山者在缺氧及高海拔特有其他应激源作用下饮食模式和激素状态的变化对这些变化进行了讨论。
