Test measuring VO2 max (American) Flyers VO2 test

VO2 max (also maximal oxygen consumption, maximal oxygen uptake or aerobic capacity) is the maximum capacity of an individual's body to transport and utilize 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 rather than mass. Accurately measuring VO2 max involves a physical effort sufficient in duration and intensity to fully tax the aerobic energy system. In general clinical and athletic testing, this usually involves a graded exercise test (either on a treadmill or on a cycle ergometer) in which exercise intensity is progressively increased while measuring ventilation and oxygen and carbon dioxide concentration of the inhaled and exhaled air. VO2 max is reached when oxygen consumption remains at steady state despite an increase in workload.Maximal oxygen uptake (VO2max) is widely accepted as the single best measure of cardiovascular fitness and maximal aerobic power. Absolute values of VO2max are typically 40-60% higher in men than in women.[1] Clearly, then, VO2max varies considerably in the population, with sex being a primary determining factor in this variability.

The average young untrained male will have a VO2 max of approximately 3.5 litres/minute and 45 ml/kg/min.[2] The average young untrained female will score a VO2 max of approximately 2.0 litres/minute and 38 ml/kg/min.[citation needed] These scores can improve with training and decrease with age, though the degree of trainability also varies very widely: conditioning may double VO2max in some individuals, and will never improve it at all in others.[3][4]

In sports where endurance is an important component in performance, such as cycling, rowing, cross-country skiing, swimming and running, world class athletes typically have high VO2 maximums. World class male athletes, cyclists and cross-country skiers typically exceed 75 ml/kg/min and a rare few may exceed 85 ml/kg/min for men and 70 ml/kg/min for women.[citation needed] Five time Tour de France winner Miguel Indurain is reported to have had a VO2 max of 88.0 at his peak [1], while cross-country skier Bjørn Dæhlie measured at an astounding 96 ml/kg/min.[5] It should also be noted that Dæhlie's result was achieved out of season and that physiologist Erlend Hem who was responsible for the testing stated that he would not discount the possibility of the skier passing 100 ml/kg/min at his absolute peak. By comparison a competitive club athlete might achieve a VO2 max of around 70 ml/kg/min.[2] World class rowers are physically very large endurance athletes and typically do not score as high on a per weight basis, but often score exceptionally high in absolute terms. Male rowers typically score VO2 maximums over 6 litres/minute, and some exceptional individuals have exceeded 8 l/min.

To put this into perspective, thoroughbred horses have a VO2 max of around 180 ml/kg/min. Siberian dogs running in the Iditarod Trail Sled Dog Race sled race have VO2 values as high as 240 ml/kg/min
Tests measuring VO2 max can be dangerous, as any problems with the respiratory and cardiovascular systems will be greatly exacerbated. Indeed many organised VO2 max tests require a medic to be present. Hence many protocols for estimating VO2 max have been developed. These generally are similar to a VO2 max test, but do not reach the maximum of the respiratory and cardiovascular systems and are called sub-maximal tests.
