VO2 max, also known as maximal oxygen uptake, is the measurement of the maximum amount of oxygen a person can utilize during intense exercise. It is a common measurement used to establish the aerobic endurance of an athlete prior to or during the course of training. It is one of several tests used to determine an athlete's cardiovascular fitness and performance capacity.
VO2 max is measured in milliliters of oxygen used in one minute per kilogram of body weight (mL/kg/min). It is based on the premise that the more oxygen an athlete consumes during high-level exercise, the more the body will generate adenosine triphosphate (ATP) energy in cells.
VO2 max is typically conducted in a sports performance lab. Either a treadmill or stationary bicycle may be used. Prior to the test, you would be outfitted with a face mask that is connected to a machine which can analyze your respiratory rate and volume alongside the concentration of oxygen and carbon dioxide in inhaled and exhaled air.
The test usually takes between 10 and 20 minutes. To prepare:
