Description
Resting respiration or resting metabolic rate (RMR) is measured under standard conditions of an 8β12-h fast and a 12-h abstinence from exercise. In an exemplary study (Haugen 2003 Am J Clin Nutr), "subjects rested quietly in the supine position in an isolated room with the temperature controlled to 21β24Β° C. RMR was measured for 15β20 min. Criteria for a valid RMR was a minimum of 15 min of steady state, determined as a <10% fluctuation in oxygen consumption and <5% fluctuation in respiratory quotient". The main difference between RMR and BMR (basal metabolic rate) is the position of the subject during measurement. Resting metabolic rate is the largest component of the daily energy budget in most human societies and increases with physical training state (Speakman 2003 Proc Nutr Soc).
