What Does Resting Metabolic Rate (RMR) Mean?
Resting metabolic rate refers to the minimal amount of caloric energy required to maintain basic physiological needs, such as breathing, heart rate, thinking, and even sleeping. The cardiopulmonary system operates autonomously in order to regulate metabolism, which necessitates the energy demanded by the body to perform systemic functions on a cyclical basis. It is the rate at which calories are burned while at rest.
REE = [3.9 (VO2) + 1.1 (VCO2)] 1.44
VO2 = volume of oxygen uptake (mL/min)
VCO2 = volume of carbon dioxide output (mL/min)
Respiratory quotient (RQ) = VCO2/VO2
