abstract="The authors describe the experience gained with nutrition for participants of ski transitions over drifting ice of the Arctic, organized by the newspaper &quot;Komsomolskaya Pravda&quot; in 1972, 1976 and 1979, including a 76-day transition towards the North Pole. Use was made of dehydrated products with a daily diet mass of 800-3300 g per man, in which fat content was 40-45% of total caloricity, and that of proteins 12-18%. Hot food was taken not less than 2 times a day (breakfast and supper). If the number of transitions exceeds 8-9 a day, it is necessary to have daytime rest and to take hot food. Additional intake of vitamins, particularly of vitamin C, is required, especially during transitions lasting over 20-25 days. If the transitions last over 35-40 days, it is required that additional food and fuel should be supplied. Optimal duration of the intervals between additional food supplies constitutes 12-15 days, the maximal permissible one 25-30 days. It is advisable to have rest days and high-caloric diet every other 15-20 days. The daily energy deficiency amounting to 1250-1500 kcal per man enables the trained group to maintain high physical and intellectual working capacity. However, overall energy deficiency should not exceed 30 000-40 000 kcal per man.<p /><p>Language: ru</p>",
