During the expedition to the North Pole, the food consumption rates were calculated on a regular basis. The mean daily energy losses of the participants of the expedition, the energy losses during skiing with a rucksack across the drifting ice were estimated and the energy metabolism curve by days was built up. The body weight of the participants averaged 78 +/- 5 kg. This made it possible to perform an overall calculation per whole group. The total energy supply with food was appraised from the total amount of the food consumed during the expedition. The total body weight loss of the participants was 11.5 kg, the energy consumption being 100.000 kkal. The total (for 7 men) energy consumption during skiing without a rucksack was calculated according to the formula: [(2,770 kkal X 28.5 days)]+ +[(2,385 kkal X 35.5 days)]. It was thus found to be equal to 1.145.300 kkal. The total energy consumption during skiing with a rucksack was calculated according to the formula: (7 men X X 449 h) and was found to be equal to 1.883.200 kkal. The total energy consumption during the expedition amounted to 3.237.500 kkal. During the expedition, the daily energy deficiency per man was 1.300-1.500 kkal. This deficiency was compensated for during rest. The maintenance of such an energy supply pattern made it possible to preserve a high level of work fitness.
在北极探险期间，定期计算食物消耗率。估算了探险参与者的平均每日能量损失、背着背包在漂流冰面上滑雪时的能量损失，并绘制了按天计算的能量代谢曲线。参与者的平均体重为78±5千克。这使得能够对整个团队进行总体计算。根据探险期间消耗的食物总量评估食物的总能量供应。参与者的总体重减轻了11.5千克，能量消耗为100,000千卡。7名男性在不背背包滑雪期间的总能量消耗根据公式[(2,770千卡×28.5天)] + [(2,385千卡×35.5天)]计算得出，结果为1,145,300千卡。背着背包滑雪期间的总能量消耗根据公式(7名男性×449小时)计算得出，结果为1,883,200千卡。探险期间的总能量消耗为3,237,500千卡。在探险期间，每人每天的能量不足为1,300 - 1,500千卡。这种不足在休息期间得到了弥补。维持这样的能量供应模式使得能够保持较高的工作体能水平。
