为了估计能量消耗（EE）的来源和变化程度，通过间接量热法在一个房间大小的人体热量计测量，一些24小时的测量进行了汇编。从酒精燃烧实验中测得的耗氧量和二氧化碳产量平均为理论值的101.5%，变异系数（CV）为1.4%。实验1由四名男性组成，他们的平均年龄为41岁，身高为179厘米，体重为84.6公斤，脂肪含量为23.5%。对每个受试者进行5次测量，间隔1天。每日和基础EE平均值分别为2852和1691 kcal/d，受试者内CV分别为2.7%和2.4%。实验2由五名男性组成，他们的平均年龄为48岁，身高为181.6厘米，体重为87公斤，脂肪含量为23%。对每个受试者进行5次测量，间隔1-3周。每日和基础EE平均值分别为2619和1837 kcal/d，受试者内CV分别为4.6%和2.9%。
To estimate sources and extent of variation in energy expenditure (EE), as measured by indirect calorimetry in a room-sized human calorimeter, a number of 24-h measurements were compiled. Measured oxygen consumption and carbon dioxide production from alcohol combustion experiments averaged 101.5% of the theoretical value with a coefficient of variation (CV) of 1.4%. Experiment 1 consisted of four men who had the following averages: age, 41 y; height, 179 cm; weight, 84.6 kg; and fat, 23.5%. Five measurements, separated by 1 d, were made on each subject. Daily and basal EE averaged 2852 and 1691 kcal/d, respectively, with a within-subject CV of 2.7% and 2.4%, respectively. Experiment 2 consisted of five men who had the following averages: age, 48 y; height, 181.6 cm; weight, 87 kg; and fat, 23%. Five measurements made on each subject were separated by 1-3 wk. Daily and basal EE averaged 2619 and 1837 kcal/d, respectively, with a within-subject CV of 4.6% and 2.9%, respectively.
