How to calculate exercise energy expenditure – SECOND PART –
In the exercise physiology’s field, energy can be presented using several ways, such as absolute oxygen consuption (L*min or ml*min), Relative Oxygen Consumption (ml*Kg*min), Metabolic Equivalent (MET), and Kilocalories. Oxygen consumption is the rate at which oxygen is used by the body and it can be expressed in both absolute and relative oxygen consumption. Absolute Oxygen Consumption is the raw volume of oxygen consumed by the body, whereas relative oxygen consumption is the volume of oxygen consumed relative to the body weight and can serve as a useful measure of fitness between individuals. METs present the energy cost of the exercise in a simple format that can be understand by the general population to gauge exercise intensity, 1 MET is equal to the relative oxygen consumption at rest, which is approximately 3,5 ml*kg*min, so, if an individual is working at 7 MET, it’s completing approximately 7 times the amount of work and using 7 times the amount of energy of that at rest. METs can be used to calculate energy expenditure over time: Kcal*min= (MET * Body mass in Kg * 3,5)/200 Now that we know all the unit of measure used to assess exercise’s energy expenditure we can understand
