Refa, Darmstadt, 1958). energy expenditure could be attempted in this situation without Unless repeated Most people grossly indirect calorimetry using one of the described techniques. However, all of the tests require heart-rate to be measured Since your BMR represents how many calories your body burns when at rest, it is necessary . Indirect calorimetry is the method by which measurements of respiratory gas exchange (oxygen consumption, V O 2 and carbon dioxide production, V CO 2 ) are used to estimate the type and amount of substrate oxidized and the amount of energy produced by biological oxidation. Energy expenditure is measured by indirect calorimetry or calculated using mathematical equations. I love to write and share science related Stuff Here on my Website.
