VO2 Max Calculator

Estimate your maximum oxygen consumption (VO2 max) using different test methods. VO2 max is the maximum rate of oxygen consumption measured during incremental exercise and is a good indicator of cardiovascular fitness.

About VO2 Max

VO2 max, or maximal oxygen uptake, is the maximum rate of oxygen consumption measured during incremental exercise (exercise of increasing intensity). It reflects the aerobic physical fitness of the individual and is an important determinant of endurance capacity during prolonged, submaximal exercise.

Rockport Walk Test

The Rockport Fitness Walking Test is a simple way to estimate VO2 max without expensive equipment. It involves walking one mile as fast as possible and then measuring your heart rate immediately at the end. The formula takes into account your weight, age, gender, walking time, and heart rate to estimate your VO2 max.

Cooper 12-Minute Run Test

The Cooper test is a simple running test of aerobic fitness where you run as far as possible in 12 minutes. The distance covered is then used to estimate VO2 max. This test is more suitable for runners who can maintain a steady pace for 12 minutes.

Heart Rate Ratio Method

This method estimates VO2 max based on your resting heart rate and maximum heart rate. The ratio between these two values correlates with cardiovascular fitness. While not as accurate as exercise tests, it provides a reasonable estimate without requiring physical exertion.

Interpreting Your Results

VO2 max values vary by age, gender, and fitness level. Higher values indicate better cardiovascular fitness and aerobic endurance. Athletes typically have higher VO2 max values than non-athletes, and values tend to decline with age. The fitness categories shown in the table above can help you understand where you fall compared to others of your age and gender.
