The relationship between resting metabolic rate and different parameters of body size was investigated among 28 female volunteers in the age group of 20--30 years. The resting metabolic rate of the subjects was determined indirectly by measuring the oxygen consumption in a closed circuit, in which the oxygen concentration was stabilised. The fat percentage of the body was determined by densitometry. The population was divided into two groups: the obese, with an average fat percentage of 33.6 and the normal-weight with an average fat percentage of 20.4. Mean values for the resting metabolic rate were 1550 kcal/24 h (6.488 MJ/24 h) for the obese and 1421 kcal/24 h (5.948 MJ/24 h) for the normal-weight group. The resting metabolic rate per kg body weight was lower in the obese than in the normal-weight persons. However, expressed per kg fat-free body mass, energy expenditure under resting conditions in the obese was higher than in the normal-weight. No single body parameter seems to be suitable in the explantation of RMR in women with substantially different fat content. The best prediction of resting metabolic rate in this population of obese and normal-weight women is obtained when both fat-free mass and fat mass are used as independent variables in a linear regression equation.
在20至30岁年龄组的28名女性志愿者中，研究了静息代谢率与不同身体尺寸参数之间的关系。通过测量封闭回路中的氧气消耗量间接测定受试者的静息代谢率，其中氧气浓度保持稳定。通过密度测定法确定身体的脂肪百分比。将人群分为两组：肥胖组，平均脂肪百分比为33.6；正常体重组，平均脂肪百分比为20.4。肥胖组静息代谢率的平均值为1550千卡/24小时（6.488兆焦/24小时），正常体重组为1421千卡/24小时（5.948兆焦/24小时）。肥胖者每千克体重的静息代谢率低于正常体重者。然而，以每千克去脂体重表示时，肥胖者静息状态下的能量消耗高于正常体重者。似乎没有单一的身体参数适合解释脂肪含量差异很大的女性的静息代谢率。当在线性回归方程中使用去脂体重和脂肪量作为自变量时，可以对该肥胖和正常体重女性群体的静息代谢率进行最佳预测。
