VO2 max

VO2 max (also maximal oxygen consumption, maximal oxygen uptake, peak oxygen uptake or maximal aerobic capacity) is the maximum rate of oxygen consumption measured during incremental exercise (exercise of increasing intensity).[1][2] The name is derived from V - volume, O2 - oxygen, max - maximum. Maximal oxygen consumption reflects the cardiorespiratory fitness of an individual and is an important determinant of their endurance capacity during prolonged exercise.

Health

VO2 max is widely used as an indicator of health. In 2016, the American Heart Association published a scientific statement[3] recommending that cardiorespiratory fitness (CRF), quantifiable as VO2 max, be regularly assessed and utilized as a clinical vital sign. This statement was based on mounting evidence that lower fitness levels are associated with high risk of cardiovascular disease, all-cause mortality, and mortality rates stemming from various types of cancers. In addition to risk assessment, the AHA recommendation cited the value measuring fitness for validating exercise prescription, physical activity counseling, and improving both patient management and patient health.
