WebJan 2, 2007 · 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 … WebRespiratory exchange ratio (RER): It is the relationship between the amount of CO 2 generated by the body and the amount of O 2 consumed by the body. When measured at the cellular level, this parameter is known as the respiratory quotient (RQ). In most cases, measurements of the breathed air are utilised to determine it.
