根据文献值，确定了 213 名成年人（86 名男性，127 名女性）的去脂质量 (FFM)、脂肪质量 (FM) 和静息能量消耗 [REE (kJ/24 h)] 之间的关系。目标是开发一个数学模型，根据身体成分预测 REE，并评估 FFM 和 FM 对 REE 的贡献。推导出以下回归方程： 1) REE = 1265 + (93.3 X FFM) (r2 = 0.727, P < 0.001)； 2) REE = 1114 + (90.4 X FFM) + (13.2 X FM) (R2= 0.743, P < 0.001); 3) REE = (108 X FFM) + (16.9 X FM) (R2 = 0.986，P < 0.001)。 FM 仅解释了考虑 FFM 后剩余变化的一小部分。包含 FFM 和 FM 的模型可用于检查随 FFM 和 FM 变化而发生的 REE 变化。为了解释 REE 的更多变异性，在未来的分析中，FFM 必须分为器官质量和骨骼肌质量。
On the basis of literature values, the relationship between fat-free mass (FFM), fat mass (FM), and resting energy expenditure [REE (kJ/24 h)] was determined for 213 adults (86 males, 127 females). The objectives were to develop a mathematical model to predict REE based on body composition and to evaluate the contribution of FFM and FM to REE. The following regression equations were derived: 1) REE = 1265 + (93.3 X FFM) (r2 = 0.727, P < 0.001); 2) REE = 1114 + (90.4 X FFM) + (13.2 X FM) (R2= 0.743, P < 0.001); and 3) REE = (108 X FFM) + (16.9 X FM) (R2 = 0.986, P < 0.001). FM explained only a small part of the variation remaining after FFM was accounted for. The models that include both FFM and FM are useful in examination of the changes in REE that occur with a change in both the FFM and FM. To account for more of the variability in REE, FFM will have to be divided into organ mass and skeletal muscle mass in future analyses.
