VO2 Max Estimator
VO2 max is the gold standard measure of cardiovascular fitness, representing the maximum amount of oxygen your body can use during intense exercise. Estimate yours using either the Cooper 12-minute run test or the 1.5-mile run time method.
VO2 max (maximal oxygen uptake) is measured in milliliters of oxygen per kilogram of body weight per minute (ml/kg/min). It reflects the combined efficiency of your heart, lungs, blood vessels, and muscles in delivering and utilizing oxygen during exercise. Higher VO2 max values indicate better cardiovascular fitness and endurance capacity.
The Cooper 12-minute run test, developed by Dr. Kenneth Cooper in 1968, estimates VO2 max from the distance covered during a 12-minute all-out effort. The formula is: VO2 max = (distance in meters - 504.9) / 44.73. The 1.5-mile run test uses completion time to estimate VO2 max.
VO2 max naturally declines with age at a rate of approximately 1% per year after age 25, but regular endurance training can significantly slow this decline. Elite endurance athletes typically have VO2 max values of 70-85 ml/kg/min for men and 60-75 ml/kg/min for women. The average untrained individual has a VO2 max of about 35-40 ml/kg/min for men and 27-31 ml/kg/min for women.
