VO2max Calculator - Resting Heart Rate Based VO2max Calculator - 1 Mile Walk Test VO2max Calculator - 3 Minute Step Test VO2max Calculator - 1.5 Mile Run-Walk Test Equations
There are four VO2max calculators on this page. Each VO2max calculator provides an estimate of your VO2max. The first calculator does not require any physical exertion, but the second, third, and fourth calculators estimate your VO2max based on your performance of a unique physical exertion test. It is important to remember that these calculators provide estimates only. They are reliable indicators of your VO2max, but the best way to truly determine your VO2max is through direct analysis of your oxygen consumption levels during a maximal physical exertion test. This requires the use of sophisticated equipment in a laboratory setting. Read more about this subject in our VO2 and VO2max article.
The equations used by these VO2max calculators are shown below.
VO2max = 15.3 x (MHR/RHR) where MHR = Maximum heart rate (beats/minute) = 208 - (0.7 x Age) RHR = Resting heart rate (beats/minute) = 20 second heart rate x 3
VO2max = 132.853 - 0.0769W - 0.3877A + 6.315G - 3.2649T - 0.1565H where W = Weight (in pounds) A = Age (in years) G = Gender factor (G = 0 for a female, G = 1 for a male) T = Test completion time (in minutes) H = Heart rate at test completion (beats/minute)
Males: VO2max = 111.33 - 0.42H Females: VO2max = 65.81 - 0.1847H where H = Heart rate (in beats/minute) after test completion
VO2max = 483/T + 3.5 where T = Test completion time (in minutes)
The estimation of maximum heart rate for the resting heart rate based VO2max calculator is derived from Tanaka, H., Monhan, K.D., Seals, D.G., Age-predicted maximal heart rate revisited. Am Coll Cardiol 2001; 37:153-156.
The VO2max calculator that is based on resting heart rate is derived from Uth N, Sørensen H, Overgaard K, Pedersen PK. Estimation of VO2max from the ratio between HRmax and HRrest--the Heart Rate Ratio Method. Eur J Appl Physiol. 2004 Jan;91(1):111-5.
The three VO2max calculators requiring physical exertion are adapted from Fahey, T., Insel, P., Roth, W., Fit & Well: Core Concepts and Labs in Physical Fitness and Wellness (Seventh Edition), McGraw-Hill, 2007.
