Resting Metabolic Rate (RMR) is a form of metabolism measurement that measures the amount of energy used by the bodies of animals in a relaxed, but not post-absorptive, state.RMR measurements require the animals be in a thermal neutral zone (or a preferred temperature range for bradymetabolic animals) and relaxed.esting Metabolic Rate (RMR) is a form of metabolism measurement that measures the amount of energy used by the bodies of animals in a relaxed, but not post-absorptive, state.
The rate at which these processes occur is measured in calories per unit of time, and is most often given in calories per day. The term basal metabolic rate (BMR) is often confused and/or interchanged with RMR or resting energy expenditure (REE).Basal metabolic rate, however, can only be found during an awake, but totally rested and post-absorptive state, and in a neutrally temperate environment.he term basal metabolic rate (BMR) is often confused and/or interchanged with RMR or resting energy expenditure (REE).
