本文研究了47名健康成年人（男23名，女24名）0300 ~ 0600 h在呼吸室中测定的睡眠代谢率（SMR）与体成分的关系。在24名女性中的16名中检查了月经周期对SMR的影响。在月经周期的排卵后阶段（估计为末次月经后18-29天），SMR平均增加7.7%（P <0.001）。逐步回归分析显示，无脂体重（FFM）、脂肪体重（FM）和月经周期对SMR均有显著影响。调整FFM和FM后，SMR（男性vs排卵前女性）没有性别差异。在此模型中加入FM是一种改进，消除了通常发现的SMR/FFM的性别差异。给出的预测方程解释了个体间SMR的85%的方差。
The relationship between sleeping metabolic rate (SMR) measured from 0300 to 0600 h in a respiration chamber and body composition was studied in 47 healthy adult subjects (23 men and 24 women). The effect of the menstrual cycle on SMR was examined in 16 of the 24 women. SMR increased in the postovulation phase of the menstrual cycle (estimated as days 18-29 after last menstruation) 7.7% on average (P less than 0.001). A stepwise regression showed that both fat-free mass (FFM), fat mass (FM), and the phase of the menstrual cycle contributed significantly to SMR. After adjustment for FFM and FM, no sex differences in SMR (men vs preovulation women) remained. The inclusion of FM in this model is an improvement that eliminates the sex difference in SMR/FFM that is usually found. A prediction equation is given that explains 85% of the variance in SMR among individuals.
