VO2 max calculator

It depends on age and sex. In the Cooper Institute percentiles used here, men aged 30–39 rate Good (60th percentile) from 44.0 and Superior (95th) from 54.0 mL/kg/min, while women of the same age rate Good from 37.8 and Superior from 47.4. Thresholds fall with age: for men aged 60–69, Good starts at 35.5. These are percentile ranks within a tested population, not clinical cut-offs.

Take the distance covered in 12 minutes of running, in metres, subtract 504.9 and divide by 44.73. Covering 2,400 m gives 42.4 mL/kg/min, and 2,800 m gives 51.3. Kenneth Cooper published the equation in JAMA in 1968 after comparing 12-minute run distances with treadmill-measured VO₂ max in US Air Force men. It assumes an all-out, evenly paced effort.

Cardiorespiratory fitness predicts survival. A 2009 JAMA meta-analysis by Kodama and colleagues (33 studies, 102,980 participants) found that each 1-MET higher maximal aerobic capacity was linked with a 13 % lower risk of death from any cause and 15 % fewer coronary and cardiovascular events. People below 7.9 METs, about 27.7 mL/kg/min, had the highest risk.

Within a few mL/kg/min for the groups they were built on. Uth's heart-rate ratio estimated measured VO₂ max with a standard error of 2.7 mL/kg/min (about 4.5 %) using a measured maximum heart rate, and 4.7 mL/kg/min (about 7.8 %) using an age-predicted one, in well-trained men. Kline's Rockport equation was fitted on 343 healthy adults aged 30 to 69.

A precisão depende dos dados inseridos e das hipóteses do método. O cálculo decimal usa 50 algarismos significativos, mas estimativas, métodos numéricos e dados de origem podem ter menor precisão; o arredondamento exibido não elimina essas limitações. Exemplos resolvidos verificados com fontes independentes: 6. Por exemplo, “Cooper: 2,800 m, man aged 25” é verificado com Python 3.8 decimal: (2800 − 504.9)/44.73 = 51.3101; Cooper Institute men 20–29: 51.1 ≤ v < 55.4 → Excellent.
