VO2 Max Formulas
1.5 Mile Run: VO2 max = 3.5 + 483 / (time in minutes)
Cooper Test: VO2 max = (distance in m − 504.9) / 44.73

Frequently Asked Questions
What is VO2 max and why does it matter?
VO2 max is the maximum rate at which your body can consume oxygen during intense exercise (measured in mL of O₂ per kg of body weight per minute). It is the best single measure of cardiovascular fitness and aerobic capacity. Higher VO2 max correlates strongly with lower risk of cardiovascular disease, metabolic syndrome, and all-cause mortality.
How can I improve my VO2 max?
High-intensity interval training (HIIT) and high-volume aerobic training most effectively raise VO2 max. Typical improvements range from 5–20% over 8–12 weeks of consistent training. Genetics set the ceiling — elite athletes are partly born with high aerobic capacity — but most people can significantly improve from baseline through consistent cardio training.
How accurate is the resting heart rate method?
The Rassmusen formula (15 × HRmax/HRrest) provides a rough estimate ±10–15% of laboratory-measured VO2 max. For more accuracy, use the 1.5-mile run test or a laboratory graded exercise test (VO2 max test). Wearable devices use proprietary formulas that achieve similar ±5–10% accuracy to the run tests.
What is my maximum heart rate?
The most common formula is Max HR = 220 − age. The Tanaka formula (208 − 0.7 × age) is slightly more accurate for older adults. Both are estimates — actual max HR varies by ±10–12 bpm between individuals of the same age.
