AMERICAN JOURNAL OF HUMAN BIOLOGY 6:71%-730 (1994) Resting Metabolic Rate and Daily Energy Expenditure Among Two Indigenous Siberian Populations
ABSTRACT Resting metabolic rate (RMR) and total daily energy expenditure (TDEE) were measured on a sample of 47 adults (35 males, 12 females) from two indigenous Siberian populations, the Evenki and Keto. The Douglas bag method of indirect calorimetry was used to measure the energy cost of lying, si...
