VARGAS Z, Melier; LANCHEROS P, Lilia  e  BARRERA P, María del Pilar. Energy expenditure in repose related to body composition in adults. rev.fac.med. [online]. 2011, vol.59, suppl.1, pp.43-58. ISSN 0120-0011.

People's energy requirements are related to their energy expenditure (EE); this is defined as being the energy which an organism consumes. It is represented by the basal metabolic rate (BMR), physical activity (PA) and dietinduced thermogenesis (DIT). The BMR is the minimum amount of energy which an organism requires to stay alive and represents 60%-70% of total energy expenditure (TEE) in most sedentary adults. The PA represents 25%- 75% of TEE whilst DIT represents around 10% of TEE. Anthropometry is the method most frequently used in studying body composition due to its simplicity, low cost and great precision.
