VO2 Max
VO2 max is the maximum rate at which a person can take in and use oxygen during intense exercise, a key measure of aerobic capacity.
VO2 max stands for maximal oxygen uptake.
Definition
VO2 max is the highest rate at which the body can consume oxygen during progressively harder exercise, usually expressed in millilitres of oxygen per kilogram of body weight per minute. It reflects the combined capacity of the heart, lungs, blood, and muscles to deliver and use oxygen, and is treated as a benchmark of aerobic fitness. It can be measured directly in a laboratory using expired-gas analysis, or estimated from field tests and wearable data.
In training, 'VO2 max intervals' are hard efforts performed near this ceiling to stress and improve oxygen uptake. VO2 max is related to but distinct from the lactate threshold: the former is a maximal capacity, while the latter describes the intensity an athlete can sustain. Genetics, training history, and altitude all influence the value.

Sports science
- Aerobic and anaerobic energyThe difference between energy the body produces with oxygen and energy it produces without it — a core idea behind why different efforts feel and last so differently.
- Force and powerThe difference between how much force the body can produce and how quickly it can produce it — the mechanics behind strength and explosiveness.
- Motor learningThe process by which practice and experience produce lasting improvements in how well a movement skill can be performed.
- Training adaptationThe process by which the body changes in response to repeated training — the underlying reason exercise makes you fitter, stronger or more skilful over time.
- Recovery and adaptationThe idea that the body adapts during recovery, not during the effort itself — which is why rest is treated as part of training rather than a break from it.
