- Weight = 70
- Age = 40
- Sex = 1
- Time for one mile = 14.5
- Heart rate at the finish = 130
- weight_lb = 70 / 0.45359237 = 154.324
- Estimated VO2 max = 132.853 - 0.0769*154.324 - 0.3877*40 + 6.315*1 - 3.2649*14.5 - 0.1565*130 = 44.1065
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula
- VO2 max = 132.853 - 0.0769 W - 0.3877 A + 6.315 S - 3.2649 T - 0.1565 HR
- W in pounds, A in years, S = 1 for men and 0 for women, T in minutes, HR in bpm.
Validated for adults from 30 to 69; outside that band treat it loosely.
This is a population formula, not a diagnosis. Individual metabolism, body composition and medical history all move the real answer, so treat the number as a starting point and talk to a clinician about anything that matters.
