VO2 Max
Sport Science
VO2 max is the maximum volume of oxygen an athlete can consume and utilize per minute per kilogram of bodyweight (mL/kg/min). It represents the ceiling of the aerobic energy system — the highest rate at which the body can produce ATP through oxidative metabolism. It is one of the most commonly cited measures of aerobic fitness and a significant predictor of endurance performance across a wide range of sports.
What Coaches Should Know
VO2 max has a significant genetic ceiling — training can improve it by roughly 15–20% in most athletes, while elite endurance athletes are largely selected for by their genetic aerobic capacity. For team sport coaches, VO2 max is a useful fitness baseline but should not be over-weighted as a performance predictor in sport contexts where speed, power, and sport-specific skills are the primary determinants.
Field-based estimates (Yo-Yo Intermittent Recovery Test, 20m Shuttle, Cooper Test) provide reasonably valid VO2 max approximations without lab equipment. For team sports the Yo-Yo IR1 and IR2 are particularly well-validated because their intermittent structure better reflects actual game demands than continuous running tests.
