Total energy expenditure and energy requirements in healthy elderly persons.
To investigate energy requirements in healthy elderly subjects, we assessed the association of total energy expenditure (TEE) with resting metabolic rate (RMR), physical activity, body composition, and energy intake in 13 individuals (aged 56 to 78 years, six women and seven men). Free-living TEE was measured using doubly labeled water, RMR was measured by respiratory gas analysis, and energy e...
متن کاملReduction in postprandial energy expenditure during pregnancy.
Energy expenditure was measured during pregnancy in seven primigravid women at 12-15, 25-28, and 34-36 weeks and after the cessation of lactation. On each occasion the resting metabolic rate and the increase in metabolic rate after ingestion of a liquid test meal were measured by indirect calorimetry. In absolute terms the resting metabolic rate increased steadily during pregnancy but when expr...
متن کاملEnergy requirements during pregnancy and lactation.
OBJECTIVE To estimate the energy requirements of pregnant and lactating women consistent with optimal pregnancy outcome and adequate milk production. DESIGN Total energy cost of pregnancy was estimated using the factorial approach from pregnancy-induced increments in basal metabolic rate measured by respiratory calorimetry or from increments in total energy expenditure measured by the doubly ...
متن کاملEnergy expenditure during overfeeding
The large inter-individual variation in weight gain during standardized overfeeding together with a weight gain that is often less than theoretically calculated from the energy excess suggest that there are differences between persons in the capacity to regulate energy expenditure and hence metabolic efficiency. Adaptive thermogenesis is defined as the regulated production of heat in response t...
متن کاملEnergy expenditure during stepping.
Previous studies from this department have emphasized the wide variations occurring amongst healthy young adults, both in the daily intake of energy as judged by records of food consumption, and in energy expenditure recorded by indirect calorimetry, for a set task such as walking under standard conditions (Kitchin and others, 1949; Delbue and others, 1949). Although no correlation was demonstr...
