Estimate VO₂ max (ml/kg/min) from Cooper distance, 1.5-mile time, or resting and max heart rate heuristics, then map to coarse fitness bands and HR training zones.
Quick answer: VO2 Max Calculator
Cooper run, 1.5-mile time, or HR-ratio method to ml/kg/min with zone heart rates.
Example: A 12-minute Cooper distance might map to a mid-40s VO₂ for a trained adult before age correction tables.
Calculations follow the documented formula on this page; rounding and input units can change the last digit-treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.
Field tests introduce pacing skill error; lab gas exchange remains gold standard.
Estimate VO₂ max (ml/kg/min) from Cooper distance, 1.5-mile time, or resting and max heart rate heuristics, then map to coarse fitness bands and HR training zones.
Inputs on this page: Method, Distance in 12 min (m) - Cooper, 1.5-mile time (seconds) - e.g. 720 for 12:00, Resting HR - HR method. Assumptions stay visible so you can reproduce the figure elsewhere.
