Respirometry + ('''Respirometry''' is the quantitative mea … '''Respirometry''' is the quantitative measurement of respiration. ''Respiration is therefore a combustion, a very slow one to be precise'' (Lavoisier and Laplace 1783). Thus the ''basic idea of using calorimetry to explore the ''sources'' and ''dynamics'' of heat changes were present in the origins of bioenergetics'' ([[Gnaiger_1983_J Exp Zool|Gnaiger 1983]]). Respirometry provides an ''indirect'' calorimetric approach to the measurement of metabolic heat changes, by measuring oxygen uptake (and carbon dioxide production and nitrogen excretion in the form of ammonia, urea, or uric acid) and converting the oxygen consumed into an [[enthalpy]] change, using the [[oxycaloric equivalent]]. Liebig (1842) showed that the substrate of oxidative respiration was protein, carbohydrates, and fat. ''The sum of these chemical changes of materials under the influence of living cells is known as [[metabolism]]'' (Lusk 1928). The amount (volume STP) of carbon dioxide expired to the amount (volume STP) of oxygen inspired simultaneously is the respiratory quotient, which is 1.0 for the combustion of carbohydrate, but less for lipid and protein. Voit (1901) summarized early respirometric studies carried out by the ''Munich school'' on patients and healthy controls, concluding that ''the metabolism in the body was not proportional to the combustibility of the substances outside the body, but that protein, which burns with difficulty outside, metabolizes with the greatest ease, then carbohydrates, while fats, which readily burns outside, is the most difficultly combustible in the organism.'' Extending these conclusions on the ''sources'' of metabolic heat changes, the corresponding ''dynamics'' or respiratory control was summarized (Lusk 1928): ''The absorption of oxygen does not cause metabolism, but rather the amount of the metabolism determines the amount of oxygen to be absorbed. .. metabolism regulates the respiration.''.. metabolism regulates the respiration.'')
Resting metabolic rate + ('''Resting respiration''' or '''resting me … '''Resting respiration''' or '''resting metabolic rate''' (RMR) is measured under standard conditions of an 8–12-h fast and a 12-h abstinence from exercise. In an exemplary study ([[Haugen 2003 Am J Clin Nutr]]), "subjects rested quietly in the supine position in an isolated room with the temperature controlled to 21–24° C. RMR was measured for 15–20 min. Criteria for a valid RMR was a minimum of 15 min of steady state, determined as a <10% fluctuation in oxygen consumption and <5% fluctuation in respiratory quotient". The main difference between RMR and BMR ([[basal metabolic rate]]) is the position of the subject during measurement. Resting metabolic rate is the largest component of the daily energy budget in most human societies and increases with physical training state ([[Speakman 2003 Proc Nutr Soc]]).man 2003 Proc Nutr Soc]]).)

If the sample consists of countable [[entity |entities]] ''X'', the [[count]] ''N''''X'' [x] in sample S is an elementary quantity, in contrast to the extensive quantities used as indicators of sample size.
