[Energy expenditure of students at the Patrice Lumumba People's Friendship University during classes].

Energy expenditures were studied in 68 first- and fourth-year male students of the Medical Department of the Patrice Lumumba University of Peoples' Friendship, who arrived to Moscow from different regions of the world: Asia, Africa, Latin America, the Middle East, the Near East, and from the USSR. The measurement of the energy expenditures was conducted at rest, when they sat reading special literature, or stood at the blackboard solving mathematical problems, and during walking at a rate of 4 km/h, applying indirect calorimetry according to the rate of the intake of oxygen and the output of carbon dioxide, with the use of Douglas-Haldane's apparatus and automatic gas analyzer. It was established that the mean values of energy expenditure per 1 kg bw during varying types of activity did not significantly differ in students of various nationalities from different regions: daily energy expenditures of students from the USSR comprised 2591 kcal, from Asia--2240 kcal, from Africa--2296 kcal, from Latin America--2470 kcal, from the Middle and the Near East--2399 kcal. Energy expenditures of the students from different regions during examinations did not significantly differ from those during the routine studying process.
