How the VO2 Max Calculator Works
This tool estimates your VO2 max (maximal oxygen consumption) using two recognized field methods: the Cooper test and the 1600-meter test. VO2 max is the gold standard for measuring aerobic capacity.
The Cooper Test
Developed by Dr. Kenneth Cooper in 1968 for the US military: VO2 max = (distance in meters - 504.9) / 44.73
Run as far as possible in 12 minutes on a flat surface. The test is maximal: you must give maximum effort for an accurate result.
The 1600m Test
A more practical alternative: VO2 max = 100.5 - 8.166 x time (minutes)
Run 1600 meters (4 laps or a mile) at maximum possible speed.
Interpreting Results
For adult males aged 30-39:
- Excellent (>52 ml/kg/min): high-level amateur athletes
- Very good (45-52): very fit and trained person
- Good (37-44): moderately active person
- Fair (33-36): sedentary but healthy person
- Low (<33): prolonged sedentary lifestyle, increased cardiovascular risk
For women, values are typically 10-15 ml/kg/min lower at the same level.
VO2 Max as a Health Indicator
Recent studies in JAMA and Lancet have shown that VO2 max is one of the best predictors of longevity and cardiovascular risk. A high VO2 max is associated with a significant reduction in all-cause mortality.
