Measurement of energy expenditure.
Measurement of energy expenditure in humans is required to assess metabolic needs, fuel utilisation, and the relative thermic effect of different food, drink, drug and emotional components. Indirect and direct calorimetric and non-calorimetric methods for measuring energy expenditure are reviewed, and their relative value for measurement in the laboratory and field settings is assessed. Where h...
متن کاملHuman energy expenditure.
HYSIOLOGICAL STUDY of man's food needs and capacity for physical work began on a systematic basis about seventy years ago. Following upon Atwater's classic experiments with a human calorimeter at the end of the last century, the validity of using rates of oxygen consumption as the basis for measuring energy expenditure (indirect calorimetry) was firmly established. Throughout this early period ...
متن کاملA model of human muscle energy expenditure.
A model of muscle energy expenditure was developed for predicting thermal, as well as mechanical energy liberation during simulated muscle contractions. The model was designed to yield energy (heat and work) rate predictions appropriate for human skeletal muscle contracting at normal body temperature. The basic form of the present model is similar to many previous models of muscle energy expend...
متن کاملUse of a Wireless Network of Accelerometers for Improved Measurement of Human Energy Expenditure
Single, hip-mounted accelerometers can provide accurate measurements of energy expenditure (EE) in some settings, but are unable to accurately estimate the energy cost of many non-ambulatory activities. A multi-sensor network may be able to overcome the limitations of a single accelerometer. Thus, the purpose of our study was to compare the abilities of a wireless network of accelerometers and ...
متن کاملNew Approaches to the Measurement of Energy Expenditure in Pigs
New procedures have been developed for the continuous measurement of energy expenditure in finisher pigs. Energy expenditure is measured from oxygen consumption calculated as the product of cardiac output and the difference in blood oxygen content between arterial and mixed venous blood (Fick principle). Key features of this approach have been the use of new technology to measure cardiac output...
