Formula & Mathematical Methodology: VO2 Max Reference Equation

VO2maxCooper = (distancem − 504.9) / 44.73
VO2maxHR = 15.3 × (maxHR / restingHR)
VO2max_Cooper = (distance_m − 504.9) / 44.73; VO2max_HR = 15.3 × (maxHR / restingHR)
  • distanceKm: Distance Km (km)
  • maxHr: Max Hr (bpm)
  • restingHr: Resting Hr (bpm)

Rounding: Intermediate calculations retain full IEEE-754 floating-point precision; displayed clinical and fitness metrics round to 1 or 2 decimal places.

Worked Example: Benchmark Scenario: VO2 Max

Compute aerobic capacity (mL/kg/min) and metabolic equivalents (METs).

  1. Enter your current anthropometric, laboratory, or training measurements in the units indicated.
  2. Substitute the values into the reference formula: VO2max_Cooper = (distance_m − 504.9) / 44.73; VO2max_HR = 15.3 × (maxHR / restingHR).
  3. Compare the primary output and supporting thresholds across all three custom SVG charts.
Result: Evaluates VO2 Max using VO2max_Cooper = (distance_m − 504.9) / 44.73; VO2max_HR = 15.3 × (maxHR / restingHR).

Frequently Asked Questions

How is the VO2 Max Estimator (Cooper 12-Min, Rockport & Uth HR Ratio) calculated?

It evaluates VO2max_Cooper = (distance_m − 504.9) / 44.73; VO2max_HR = 15.3 × (maxHR / restingHR) using your entered parameters and displays supporting clinical or training thresholds alongside three interactive SVG visualizations.
