Measurement of energy expenditure
Pediatric Blood & Cancer, 2011AbstractAlthough investigators have been engaged in the study of human energy metabolism for over 100 years, there remain unanswered questions regarding the role that energy expenditure plays in human health and disease. A critical examination of available methods for measurement of the various components of daily energy expenditure is presented. Using

Measurement of Energy Expenditure
2014Background At the present state of the art, energy expenditure is measured with indirect calorimetry, where energy production is calculated from oxygen consumption, carbon dioxide production and urine-nitrogen loss. Daily energy expenditure consists of three components, i.e.

Activity and energy expenditure
Canadian Journal of Physiology and Pharmacology, 1990The influence of small changes in activity on energy expenditure and hence on energy requirements and energy balance is assessed. Evidence from direct and indirect calorimetry suggests that differences in spontaneous minor activity could readily alter 24-h energy expenditure by as much as 20%. This compares with values in the order of 10% for moderate

The Measurement of Energy Expenditure
The Journal of Nutrition, 1991This is a brief account of the development of energy expenditure measurements, from speculations by early philosophers on the nature of the "innate fire," through the beginnings of quantitative animal calorimetry and to the combined material and energy balances of Rubner and of Atwater and Benedict, which established the science of nutritional energy ...

Energy expenditure of obese subjects living in a respiration chamber is higher than that of lean controls; this is due to a greater basal metabolic rate in the obese. Groups of obese subjects with a family history of obesity and/or a childhood onset of obesity have a reduced thermogenic response after glucose or meal ingestion.

ENERGY EXPENDITURE: BIOSYNTHESES
1968In an actively growing culture of micro-organisms, ATP formed by the energy-yielding metabolism of the organisms is rapidly expended in a variety of metabolic processes. An appreciable amount of ATP is consumed in the biosynthesis of new cell components, including energy-storage compounds such as glycogen and poly-β-hydroxybutyrate; but there are other

Hypocretin/orexin and energy expenditure
Acta Physiologica, 2010AbstractThe hypocretins or orexins are endogenous neuropeptides synthesized in discrete lateral, perifornical and dorsal hypothalamic neurones. These multi‐functional neuropeptides modulate energy homeostasis, arousal, stress, reward, reproduction and cardiovascular function.

Energy intake and energy expenditure in the elderly
American Journal of Human Biology, 1996This review briefly examines the effects of aging on resting metabolic rate, thermic effect of a meal, and the energy expenditure of physical activity. Thereafter, the effects of advancing age on total daily energy expenditure as assessed from doubly labeled water studies are examined.
