VO2 max (also maximal oxygen consumption, maximal oxygen uptake, peak oxygen uptake or aerobic capacity) is the maximum capacity of an individual's body to transport and use oxygen during incremental exercise, which reflects the physical fitness of the individual. The name is derived from V - volume per time, O2 - oxygen, max - maximum. VO2 max is expressed either as an absolute rate in litres of oxygen per minute (l/min) or as a relative rate in millilitres of oxygen per kilogram of bodyweight per minute (ml/kg/min), the latter expression is often used to compare the performance of endurance sports athletes. A less size-biased measure is to divide by \sqrt[3]{mass^2} rather than mass. ... VO2 max is properly defined by the Fick equation: \mathrm{VO_2\; max} = Q(\mathrm{CaO_2} - \mathrm{CvO_2}), when these values are obtained during an exertion at a maximal effort. where Q is the cardiac output of the heart, CaO2 is the arterial oxygen content, and CvO2 is the venous oxygen content. source: http://en.wikipedia.org/wiki/Fick_Equation#Fick_equation
