Basal metabolic rate is the rate of energy expenditure per unit time by endothermic animals at rest. It is reported in energy units per unit time ranging from watt to ml O₂/min or joule per hour per kg body mass J/. Proper measurement requires a strict set of criteria be met.
Age, nutrition, and activity are factors that influence basal metabolic rate. ... Body size: Metabolic rate increases as weight, height, and surface area increase. Body composition: Fat tissue has a lower metabolic activity than muscle tissue. As lean muscle mass increases, metabolic rate increases.
