Basal Metabolic Rate
is the rate of metabolism
when an individual is at rest in a warm environment
and is in the post absorptive state, and has not
eaten for at least 12 hours. The release of energy
in this state is only sufficient for the vital
organs such as the heart, lungs, nervous system, and
kidneys. BMR decreases with age and with the loss of
lean body mass. Regular cardiovascular exercise can
increase BMR. Other factors can also affect BMR,
such as illness, environmental temperature, and
Basal metabolic rate is measured under very restrictive circumstances. A more common and closely related term used in many cases is resting metabolic rate (RMR), which is measured under less strict conditions. It is also important that a person is not sympatically stimulated when the BMR is measured as it could affect the value of the BMR that is being measured.
