这项研究确定了在测量前一晚在家与在诊所度过的受试者对静息代谢率(RMR)的影响。10名受试者参加了6次随机的RMR测量；3次测量是在受试者在家进行测量的前一天晚上(H1、H2和H3)进行的，3次是在他们在临床环境中睡觉后(C1、C2和C3)进行的。两组间差异无统计学意义(P<；耗氧量(VO2，mL/min)、RMR(kJ/min，kJ.kg身体重量-1.h-1或kJ.kg脱脂质量-1.h-1)或呼吸交换率(RER)在六个RMR测量中的任何一个之间，或三个家庭试验的平均值之间(VO2=216+/-41mL/min，RER=0.80+/-0.04，心率=51+/-3次/分钟，通气量=7.1+/-1.1 L/分)与三个临床试验(VO2=2 16+/-45毫升/分，肺活量=0.80+/-0.0 4，心率=5 2+/-5次/分，通气量=7.0+/-1.1 L/分)比较。我们的结论是，在大多数情况下，受试者在RMR评估前一晚在测量设施度过并不重要。然而，当要评估基础代谢率时，通常需要在临床设施中过夜。
This study determined the effect on resting metabolic rate (RMR) of subjects spending the night before measurement at home vs at a clinic. Ten subjects participated in six randomized RMR measurements; three measurements were made after subjects slept the evening before the measurements in their home (H1, H2, and H3) and three after they slept in a clinical setting (C1, C2, and C3). There were no significant differences (P < 0.05) in oxygen consumption (VO2, mL/min), RMR (kJ/min, kJ.kg body wt-1.h-1, or kJ.kg fat-free mass-1.h-1), or respiratory exchange ratio (RER) between any of the six RMR measurements, or between mean values for the three home trials (VO2 = 216 +/- 41 mL/min, RER = 0.80 +/- 0.04, heart rate = 51 +/- 3 beats/min, ventilation = 7.1 +/- 1.1 L/min) vs the three clinical trials (VO2 = 216 +/- 45 mL/min, RER = 0.80 +/- 0.04, heart rate = 52 +/- 5 beats/min, ventilation = 7.0 +/- 1.1 L/min). We conclude that under most circumstances it is not important that subjects spend the night before RMR assessment at the measurement facility. However, when basal metabolic rate is to be assessed, an overnight stay at the clinical facility would generally be necessary.
