VO2 Max Calculator
Estimate your VO2 Max, the ultimate measure of cardiovascular fitness, using your resting heart rate and age.
What is VO2 Max?
VO2 Max (maximal oxygen uptake) is the maximum rate at which your heart, lungs, and muscles can effectively use oxygen during exercise. It is widely considered the ultimate indicator of cardiovascular fitness and aerobic endurance.
How It Is Estimated
A true VO2 Max test requires running on a treadmill with an oxygen mask in a sports science laboratory. However, researchers (like Uth, Sørensen, Overgaard, and Pedersen) have found that the ratio between your Maximum Heart Rate and Resting Heart Rate provides a highly accurate mathematical estimation.
The Formula
VO2 Max = 15.3 x (Max Heart Rate / Resting Heart Rate)
Frequently Asked Questions
What is a good VO2 Max?
For an average 30-year-old male, a score of 40-50 mL/kg/min is considered good. For females of the same age, 35-43 mL/kg/min is good. Elite endurance athletes (like Tour de France cyclists) often score above 80.
