FAQ
What is a good VO2 max score?
Average adults: 30-40 ml/kg/min. Good fitness: 40-50 (men), 35-45 (women). Elite endurance athletes: 60-85 ml/kg/min. Scores decline 10% per decade after age 25. Higher VO2 max = better cardiovascular health and endurance performance.
Which test is most accurate: Cooper, race time, or Rockport?
Cooper 12-minute test is most reliable field test (run as far as possible in 12 min). Race times work well but depend on pacing. Rockport walk (1-mile with heart rate) is good for beginners/elderly. Laboratory VO2 max test (treadmill with breathing mask) is gold standard.
How can I improve my VO2 max?
Best method: High-Intensity Interval Training (HIIT) - 4x4 minutes at 85-95% max HR with 3-min recovery, 2x/week. Also effective: long slow distance (80% max HR) 3-4x/week. Improvements: beginners +15-25%, trained athletes +5-10% over 8-12 weeks.
