This VO2 Max Aerobic Capacity Calculator estimates the VO2 max aerobic capacity through the four most common methods from resting heart rate to activity tests:

A) VO2 max based on Resting Heart Rate
VO2 max = 15.3 x MHR / (Number of heart beats in 20 seconds x 3)
where MHR = 208 – (0.7 x Age)

B) VO2 max based on One Mile Walk Test
VO2 max = 132.853 - 0.0769 x Weight in lbs - 0.3877 x Age in years + 6.315 x (0 if Female, 1 if Male) - 3.2649 x Test completion time in minutes - 0.1565 x Heart rate at test completion

C) VO2 max based on Three Minute Step Test
VO2 max (men) = 111.33 - 0.42 x Heart rate at test completion
VO2 max (women) = 65.81 - 0.1847 x Heart rate at test completion

D) VO2 max based on 1.5 Mile Run / Walk Test
VO2 max = 483 / Test completion time (minutes) + 3.5
