Absolute and Relative Vo₂ Max
Aerobic fitness is expressed in two ways: Absolute Vo₂ max, and relative Vo₂ max. Absolute Vo₂ max is simply the amount of oxygen that the body uses during the performance of maximal effort; it is expressed in liters of oxygen per minute (liters/min). Relative Vo₂ max is the absolute Vo₂ max divided by body weight in kilograms and it is expressed in milliliters of oxygen per body weight per minute (ml/kg/min).		In general, absolute Vo₂ max is important in activities in which body weight is not lifted such as in swimming, cycling, and the lifting of weights and other objects. Vo₂ max is mainly a function of work capability of the large muscle groups of the legs. Many good swimmers do not show high Vo₂ max because of the specialized upper body work involved in this activity. Relative Vo₂ max is important in such activities as walking, running, climbing uphill in which body weight is lifted.
