๐ซVO2 Max Calculator
Estimate your VO2 max from four validated methods โ resting heart rate, Cooper 12-minute run, 1.5-mile run, or Rockport 1-mile walk. Enter your result to see your estimated aerobic capacity and where you stand by age and sex.
This calculator provides educational fitness estimates only โ not medical advice, a clinical assessment, or a substitute for a laboratory graded-exercise test. Field-test VO2 max estimates carry a typical error of ยฑ5โ10 ml/kg/min and results differ between methods, so compare the same method over time rather than across methods. The Cooper run, 1.5-mile run, and Rockport walk test require strenuous or maximal effort. Warm up properly before any field test. Do not attempt an all-out test if you have a heart or respiratory condition, feel unwell, or have been advised against vigorous exercise without medical clearance. Stop immediately if you experience chest pain, significant shortness of breath, dizziness, or other symptoms. Consult a qualified health professional before starting an intense training programme or if you have any health concerns.
