Energy used to exercise is called exercise activity thermogenesis (EAT), while unintentional movements are called non-exercise activity thermogenesis (NEAT). only practicable procedure is to make the subject stop exercising Basal metabolic rate (BMR), the minimal amount of energy expended for homeostatic processes, is a major component (about 6080%) of total EE in free-living individuals and is an even larger component for hospital-bound patients due to a decreased level of physical activity. It is considered the reference, or criterion, method for measuring energy expenditure under controlled conditions (ie, in a laboratory). This is a cycling-specific version of the general equation Power = Force x Velocity. What do you mean by permeability of membrane?
