The authors studied energy, nitrous, lipid, carbohydrate, mineral and vitamin metabolism in subjects aged 18-21 years exposed during 8 days to high physical loads within 4540-8495 kkal/day and given the daily diet consisting of natural food with an energy value of 3220 kkal. During the observation period, the body weight losses amounted to 3.7 kg (5.3%) of the initial weight magnitude on the average, whereas the amount of fatty component dropped by 23.9%. The test subjects manifested a decrease in work fitness, a fall in the main metabolism by 23%, reduction of the respiratory ratio to 0.67, and considerable alterations in the majority of metabolic indices. The recovery of the body status till the attainment of the initial level lasted 3-5 days. The subjects with a good physical stature tolerated the period of inadequate nutrition fairly well.
作者对18至21岁的受试者进行了研究，这些受试者连续8天承受4540 - 8495千卡/天的高强度体力负荷，并给予能量值为3220千卡的天然食物组成的日常饮食。在观察期内，体重平均下降了3.7千克（占初始体重的5.3%），而脂肪成分的量下降了23.9%。受试对象表现出工作适应性下降，基础代谢率下降23%，呼吸商降至0.67，并且大多数代谢指标发生了显著变化。身体状态恢复到初始水平持续了3至5天。身体素质良好的受试者对营养不足的时期耐受得相当好。
