How this is calculated
Rockport walk test: VO2max = 132.853 − 0.0769×weight(lb) − 0.3877×age + 6.315×gender − 3.2649×time − 0.1565×HR

Assumptions used in this calculation

  • Field-test estimate: This is a walk-test estimate, not a laboratory VO2 max measurement.

About this calculator

Estimate your VO2 max, a standard measure of cardiovascular fitness, using the Rockport 1-mile walk test formula: walk one mile as fast as you can without running, then enter your time and finishing heart rate.

Worked example

30-year-old male, 70kg, 14-minute mile, 130bpm finish

Result: VO2 max ≈ 42 ml/kg/min (Good)
