What is VO2 Max?

VO2 Max (maximal oxygen consumption) refers to the maximum amount of oxygen that an individual can utilize during intense or maximal exercise. It is measured in milliliters of oxygen used in one minute per kilogram of body weight (ml/kg/min). It is widely considered the best indicator of cardiovascular fitness and aerobic endurance.

How does this calculator work?

While the most accurate way to measure VO2 Max is in a laboratory setting using a treadmill or stationary bike and a mask that measures oxygen and carbon dioxide, this calculator uses the validated Uth-Sørensen-Overgaard-Pedersen estimation method based on your age and resting heart rate.

How to improve your VO2 Max

  • Consistency: The number one way to improve is keeping a consistent running schedule.
  • Interval Training: Incorporating high-intensity interval training (HIIT) pushes your aerobic capacity.
  • Long Runs: Building a solid aerobic base through easy long runs allows your body to process oxygen more efficiently.
