When we breath our respiratory system gathers oxygen from the environment, and processes it to be delivered to the tissues of our body (muscles, bones, ligament, skin, tendons). As our cells us the oxygen they produce carbon dioxide. Which is then transported to the heart and lungs in the deoxygenated blood and released through exhaling. Maximum oxygen consumption is called VO2 max. VO2 max is the highest rate of oxygen transport and utilization achieved at maximal physical exertion. METs are the one of the best ways to gauge what your cardio respiratory max is. A MET means metabolic equivalent. The chart above shows how many METS per activity...This is important because using the formula below we can find out how many calories are burned during any activity. This is awesome because now you can know how many calories your burning while you run for 20 minutes, jump rope for 5, and/or go on a long walk for 30 etc. 1 liter of O2 consumed = 5 cal.; 1 MET = 3.5 ml/kg/min (at rest caloric burn); 1 Lb.=2.2 kgBody Weight ("BW") in kg = BW in Lbs / 2.2
THE FORMULA----->METS*x 3.5 x BW in kg / 1000 x 5 = Calories / Minute
