(RMR) (rest'ing met'ă-bol'ik rāt)
Minimum number of calories needed to support basic functions, including breathing and circulation.

metabolic rate

the rate of energy expenditure during any given state of rest or specified activity. Commonly assessed in terms of respiratory gas exchange (indirect calorimetry) by obtaining values for oxygen uptake and carbon dioxide output, and relating these to the equivalent release of energy in kJ or kcal per minute. basal metabolic rate (BMR) the rate of energy expenditure which is required at complete rest for all cellular function, to maintain the systems of the body and to regulate body temperature. It is measured before the person rises in the morning after fasting for at least 12 hours, requiring an overnight stay under controlled conditions in the laboratory. BMR is influenced by age, sex, body size and fat-free mass. In most sedentary healthy adults it accounts for approximately 60-80% of total daily energy expenditure, amounting to ∼4000-7000 kJ per 24 hours for individuals with body mass within the normal range. In elite endurance athletes during days of competition or training, BMR may represent only 38-47% of total daily energy expenditure. resting metabolic rate (RMR) is more commonly measured, since it allows the person to sleep at home, to travel to the laboratory in the morning and to rest there before RMR is assessed. Values for BMR and RMR usually differ by less than 10% and sometimes are used interchangeably. RMR is typically close to 4.2 kJ per kg of body mass per hour or 3.5 mL O2 utilized per kg of body mass per minute. See also Douglas bag method, oxygen consumption.
