Document Summary

Regulation of metabolism and body temperature: basal metabolic rate (bmr) Metabolic rate is de ned as body"s rate of energy expenditure per hour, which is essentially the total heat produced by all of the chemical reactions and mechanical work of the body. Bmr is the rate at which energy is expended (heat produced) by the body per unit time under controlled (basal) conditions 12 hours after a meal, at rest. It can be measured by oxygen consumption (indirect) or by a calorimeter (to measure heat production by the body). Measure of the energy used to maintain only the essential activities when awake (breathing, resting levels of organ function), essential the energy cost of living. Reported as kcal/m2/hr, an average 70kg adult has a bmr of 60-72 kcal/hr. Bmr is in uenced by: body surface area, age, gender, stress and hormones. Bmr is inversely proportional to age (need energy for growth)
