Energy cost of rest and various common daily activities was measured in 7 male and 16 female medical students by using a Max-Planck respirometer and a Lloyd's gas analysis apparatus. The average weight of male and female subjects during the course of the study was 67.3 +/- 14.2 and 51.2 +/- 5.1 kg, respectively. The average energy expenditure per day was estimated from a diary of activities for a period of 7 days. The average daily intake of energy was computed from food tables and based on weighed amounts of raw materials of food consumed over the same 7-day period when energy expenditure was determined. The average energy expenditure of rest and different activities was found to be significantly lower than the figures published for western subjects. The daily energy intake and expenditure were 2,138 +/- 217 kcal (9.0 +/- 0.9 MJ) and 1,894 +/- 168 kcal (8.0 +/- 0.7 MJ), respectively, in male medical students, giving a positive balance of 244 kcal (1.0 MJ). The values of the same in female medical students were 1,711 +/- 292 kcal (7.2 +/- 1.2 MJ) and 1,474 +/- 211 kcal (6.2 +/- 0.9 MJ) with a balance of 237 kcal (1.0 MJ).
通过使用马克斯 - 普朗克呼吸计和劳埃德气体分析仪，对7名男性和16名女性医学生在休息及各种日常常见活动时的能量消耗进行了测量。在研究过程中，男性和女性受试者的平均体重分别为67.3±14.2千克和51.2±5.1千克。每日平均能量消耗是根据7天的活动日记估算得出的。每日平均能量摄入量是根据食物表计算得出的，基于在确定能量消耗的同一7天内所消耗食物原材料的称重数量。结果发现，休息及不同活动的平均能量消耗显著低于针对西方受试者公布的数据。男性医学生的每日能量摄入量和消耗量分别为2138±217千卡（9.0±0.9兆焦耳）和1894±168千卡（8.0±0.7兆焦耳），能量平衡为正244千卡（1.0兆焦耳）。女性医学生的相应数值分别为1711±292千卡（7.2±1.2兆焦耳）和1474±211千卡（6.2±0.9兆焦耳），能量平衡为237千卡（1.0兆焦耳）。
