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
2014At 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., maintenance expenditure, diet-induced energy expenditure and activity-induced energy ...

Overfeeding and energy expenditure in humans [PDF]
The effect of overfeeding on energy expenditure was investigated in 23 young men subjected to a 353-MJ energy intake surplus over 100 d. The major part of this excess (222 MJ) was stored as body energy. The increase in energy cost of weight maintenance amounted to 52 MJ and was proportional to body weight gain.

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

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

Clinics in Endocrinology and Metabolism, 1984
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.

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 ...

Skin Temperature and Energy Expenditure
Annals of Nutrition and Metabolism, 1990The value of mean skin temperature as an estimate of energy expenditure was verified in a sample of 10 normal-weight adult male subjects. Measurements were carried out with thermometric probes under conditions of rest and environmental thermoneutrality. Total heat losses were then calculated through a computerized complex mathematical formula.

Machiguenga energy expenditure
Ecology of Food and Nutrition, 1977This article presents the results of a study of energy expended at typical activities and on average days, by adult women and men of a hunter‐gatherer‐horticulturalist population in south‐eastern Peru. Marked differences between the sexes in patterns of energy use are presented.
