VO2 Max Calculator

Estimate your maximal oxygen uptake (VO2 Max) using the Rockport Walking Test or resting heart rate methods.

🫁

Input Parameters

Enter details for calculation.

Est. VO2 Max

46.7 ml/kg/min
💡

Expert Tip

VO2 Max represents the maximum volume of oxygen you can utilize during intense exercise. Higher values indicate superior aerobic fitness.

Calculation Methodology & Details

📐

Formula

VO2 Max = 15 × (Max_Heart_Rate / Resting_Heart_Rate) Max HR ≈ 220 − Age

Uses the Uth-Sørensen-Overgaard-Pedersen index, a reliable estimation based on vascular heart rate ratios.

FAQ

How is Mean Arterial Pressure (MAP) calculated?
MAP reflects average arterial pressure during a cardiac cycle. It is calculated as DP + 1/3(SP - DP), where DP is diastolic pressure and SP is systolic pressure.
What is the clinical significance of a prolonged QTc interval?
A QTc interval above 450 ms in men or 460 ms in women increases the risk of ventricular arrhythmias, specifically Torsades de Pointes.
Can risk scores replace acute clinical evaluation?
No. Risk calculators like HEART, TIMI, or GRACE assist emergency clinicians, but should never replace clinical judgment or urgent medical intervention in acute coronary syndromes.
