VO2 Max Calculator
Estimate your VO2 max from your maximum and resting heart rates.
Estimated VO2 max47.5ml/kg/min
This is the Uth–Sørensen heart-rate ratio estimate: VO2 max ≈ 15 × (max heart rate ÷ resting heart rate). With a max HR of 190 and a resting HR of 60, that is 15 × (190 ÷ 60) ≈ 47.5 ml/kg/min. A lower resting heart rate (better fitness) raises the estimate. It is an approximation — a lab graded-exercise test is the gold standard.

Questions
How is VO2 max estimated from heart rate?
The heart-rate ratio method estimates VO2 max as 15 × (maximum heart rate ÷ resting heart rate). A max of 190 and resting of 60 gives about 47.5 ml/kg/min.
Why does a low resting heart rate help?
A lower resting heart rate usually signals a stronger, more efficient heart, which raises the ratio and the VO2 max estimate. Endurance training tends to lower resting heart rate over time.
