Detailed explanation-1: -What is VO2 max? VO2 max, or maximal oxygen consumption, refers to the maximum amount of oxygen that an individual can utilize during intense or maximal exercise. This measurement is generally considered the best indicator of cardiovascular fitness and aerobic endurance.
Detailed explanation-2: -Respiratory system In an average young male, resting oxygen consumption is about 250 ml min−1 and in an endurance athlete oxygen consumption during very high intensity exercise might reach 5000 ml min−1.
Detailed explanation-3: -The highest ever recorded VO2 max is 96 ml/kg/min, attributed to Bjørn Dæhlie, and 77 ml/kg/min in women.
Detailed explanation-4: -Maximal Oxygen Uptake. VO2 max is an objective measurement of exercise capacity: it defines the upper limits of the cardiopulmonary system. It is determined by an individual’s capacity to increase heart rate, augment stroke volume, and direct blood flow to the active muscles.
