Question

What does basal metabolic rate (bmr) measure?

Answer 1

Answer:

It is the rate at which a person uses energy when he or she uses energy when the body is at rest.

Explanation:

So basically in other words  it is the number of calories required to keep your body functioning while you are not doing any physical activities. I hope this helps you out :)

Answer 2

BMR is measured under very restrictive circumstances when a person is awake. An accurate BMR measurement requires that the person's sympathetic nervous system not be stimulated, a condition which requires complete rest. A more common measurement, which uses less strict criteria, is resting metabolic rate (RMR).
