Schofield Equation
The Schofield Equation is a method of estimating the basal metabolic rate (BMR) of adult men and women published in 1985. This is the equation used by the World Health Organization, WHO in their technical report series. The equation that is recommended to estimate BMR by the US Academy of Nutrition and Dietetics is the Basal metabolic rate#BMR estimation formulas, Mifflin-St. Jeor equation. The equations for estimating Basal metabolic rate, BMR in kJ/day (kilojoules per day) from body mass (kg) are:Energy Requirements of Adults, Report of a Joint FAO/WHO/UNU Expert Consultation (See table 5.2). Men: Women: The equations for estimating BMR in kcal/day (kilocalories per day) from body mass (kg) are: Men: Women: Key: W = Body weight in kilograms SEE = Standard ...

Basal Metabolic Rate
Basal metabolic rate (BMR) 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 (joule/second) to ml O2/min or joule per hour per kg body mass J/(h·kg). Proper measurement requires a strict set of criteria to be met. These criteria include being in a physically and psychologically undisturbed state and being in a thermally neutral environment while in the post- absorptive state (i.e., not actively digesting food). In bradymetabolic animals, such as fish and reptiles, the equivalent term standard metabolic rate (SMR) applies. It follows the same criteria as BMR, but requires the documentation of the temperature at which the metabolic rate was measured. This makes BMR a variant of standard metabolic rate measurement that excludes the temperature data, a practice that has led to problems in defining "standard" rates of metabolism for many mammals. Metabolism comprises the processes that the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
