[A physiologic approach to determining and classifying the energy requirements of the population of the USSR]

To develop more accurate recommendations on physiological requirements of the population of the USSR in food substances and energy the author has suggested a new classification of energy expenditure based on the account of the human physical activity with respect to the basal metabolism values. The data are presented on the basal metabolism for different populations depending on the sex, age and body mass. Energy expenditures are classified in the values relative to the basal metabolism. Daily energy expenditures of men have been divided into 5 groups depending on the hardness of their labour: very easy, easy, not very hard, hard and very hard labor. Four groups of physical activity or labor have been suggested for women, these groups correspond to the first four groups developed for men.
