VO₂ Max Estimate
47.7
mL/kg/minThis score indicates that under maximal exertion, your body can utilize ~47.7 milliliters of oxygen per kilogram of body weight every minute.
How The Estimation Methods Work
The simplest method entirely based on resting metrics. It uses the ratio between your estimated Maximum Heart Rate (derived from your age) and your Resting Heart Rate. A very low resting heart rate indicates a highly efficient cardiovascular system.
Developed in 1968 by Kenneth H. Cooper, MD for the US Military. It requires you to run as far as you possibly can exactly within 12 minutes. The total distance covered strongly correlates linearly with your body's ability to utilize oxygen under load.
Ideal for those who cannot or should not run. You briskly walk exactly 1 mile as fast as comfortably possible, noting the time and your heart rate the moment you finish. A regression equation factoring in your weight and age calculates the VO2 max.
