VO₂ Max Guide
What VO₂ max is, how Cooper and Rockport field tests estimate it, age/sex norms, and how to use the free KinesoScore VO₂ calculator.
Frequently asked questions
- What is VO₂ max?
- VO₂ max is maximal oxygen uptake — an estimate of how much oxygen your body can use during intense exercise. It is a common marker of cardiorespiratory fitness, usually reported in ml/kg/min.
- How does KinesoScore estimate VO₂ max?
- KinesoScore estimates VO₂ max from the Cooper 12-minute run or the Rockport 1-mile walk field test, then optionally compares the result with age- and sex-based reference percentiles.
- What is a good VO₂ max?
- A good VO₂ max depends on age and sex. Near the 50th percentile is roughly average for your group; the 75th percentile and above are typically considered good to excellent on Cooper Institute / ACSM-style tables.
- Is a field-test VO₂ the same as a lab test?
- Field tests are practical estimates, not metabolic-cart lab measurements. They are useful for training feedback and trends, but conditions, pacing, and effort can affect accuracy.
