VO2 is used to designate the volume of oxygen within the blood that is consumed by the body's tissues. Specifically, it is often measured as the volume of oxygen (in milliliters) per kilogram bodyweight per minute. It is an indication of a person's aerobic fitness capacity when engaged in an endurance-type exercise (e.g., jogging, biking, swimming). VO2 escalates as the intensity of exercise increases up to a certain threshold called VO2-max. The magnitude of VO2-max is largely dependent on the cardiovascular health and age of the individual. It is favorable to have a high VO2 for a particular exercise with minimal bodily fatigue--this is indicative that the heart is functioning efficiently. A good personal trainer should ascertain his or her client's VO2-max (either directly by performing a graded exercise test or indirectly by assessing heart rate response to at least two exercise intensity levels) in order to prescribe an appropriate intensity level of cardiorespiratory exercise.
