VO2 Max Cardiorespiratory Fitness Mathematics

VO2 max calculator estimates cardiorespiratory fitness from resting heart rate, the Cooper 12-minute run test, or the Rockport walk test.

Standardized Mathematical Formula
VO2 Max = 15.3 × (HRmax ÷ HRrest)

The Uth-Sørensen-Overgaard-Pedersen equation estimates VO2 max (maximal oxygen uptake, in mL/kg/min) from the ratio of estimated maximum heart rate to resting heart rate — a simple field method requiring no exercise test.

Variables:
HRmax:Estimated maximum heart rate (Tanaka formula: 208 − 0.7 × age)
HRrest:Resting heart rate, measured after waking
How It Works (Step-by-Step)
  • 1Enter your age and resting heart rate (or use the Cooper/Rockport test results instead).
  • 2View your estimated VO2 max and fitness classification.
Real-World Numerical Example
Age 30 with a Resting Heart Rate of 55

A 30-year-old has a resting heart rate of 55 beats per minute.

•Estimated HRmax (Tanaka): 208 − 0.7 × 30 = 187 BPM.
•VO2 Max: 15.3 × (187 ÷ 55) = 15.3 × 3.40 = 52.0 mL/kg/min.
Result: The estimated VO2 max is 52.0 mL/kg/min, in the "excellent" cardiorespiratory fitness range.
Calculation Best Practices & Tips
Use the Brzycki formula (1RM = Weight / (1.0278 - 0.0278 * Reps)) for sub-maximal sets between 2 and 10 repetitions.
Pace consistency during the first half of a marathon is the single greatest predictor of achieving personal record finish times.

Frequently Asked Questions (FAQ)

For adults, above 45 mL/kg/min is generally considered excellent, 38-44 is good/average, and above 55 is elite-athlete territory — ranges vary by age and sex.

High-intensity interval training (HIIT) and sustained aerobic endurance work are the two most effective, evidence-backed methods for raising VO2 max over 6-12 week training blocks.
