VO2 Max Calculator
Calculate your aerobic capacity (VO2 max) using 5 different test methods. VO2 max measures the maximum amount of oxygen your body can use during intense exercise.
Tip: Measure first thing in the morning while lying down for best accuracy.

Understanding VO2 Max
What is VO2 Max?
VO2 max (maximal oxygen uptake) is the maximum rate at which your body can absorb and use oxygen during intense exercise. It's measured in milliliters of oxygen per kilogram of body weight per minute (ml/kg/min) and is considered the gold standard for measuring aerobic fitness.
Why Does VO2 Max Matter?
- Cardiovascular Health: Higher VO2 max is associated with lower risk of heart disease and all-cause mortality
- Endurance Performance: Elite endurance athletes typically have VO2 max values of 70-85 ml/kg/min
- Longevity: Studies show each 1 MET (~3.5 ml/kg/min) increase correlates with 13% lower mortality risk
- Fitness Tracking: VO2 max is an objective measure to track fitness improvements over time
How to Improve VO2 Max
High-Intensity Interval Training (HIIT)
Short bursts of intense exercise followed by rest periods. Most effective for improving VO2 max.
Long Steady-State Cardio
30-60 minutes of continuous moderate-intensity exercise like jogging, cycling, or swimming.
Tempo Training
Exercise at 80-90% of max HR for extended periods to push your aerobic threshold.
Consistency
Train 3-5 times per week. Improvements of 5-20% are possible within 3-6 months.
Factors Affecting VO2 Max
- Age: VO2 max typically declines ~1% per year after age 25
- Sex: Men generally have 10-15% higher VO2 max than women due to body composition
- Genetics: Up to 50% of VO2 max potential may be hereditary
- Training Status: Regular exercise can improve VO2 max by 15-30%
- Altitude: Living/training at altitude can increase oxygen-carrying capacity
Frequently Asked Questions
Which VO2 max test method is most accurate?
The gold standard is a lab test with gas analysis during maximal exercise. Among field tests, the 1.5-mile run test is most accurate for active individuals, while the walking test is better for beginners or older adults. The resting heart rate method is least accurate but most convenient.
What is a good VO2 max score?
For men, a "good" VO2 max ranges from 40-50 ml/kg/min depending on age. For women, 35-45 ml/kg/min is considered good. Elite endurance athletes can reach 70-85+ ml/kg/min. However, even modest improvements in VO2 max provide significant health benefits.
How often should I test my VO2 max?
Every 4-8 weeks is reasonable if you're actively training to improve it. For general fitness monitoring, every 3-6 months is sufficient. Significant improvements typically require at least 6-12 weeks of consistent training.
Can I improve my VO2 max at any age?
Yes! While VO2 max naturally declines with age, people of all ages can improve their aerobic capacity through training. Studies show seniors can improve VO2 max by 10-30% with proper exercise programs. Active older adults often have VO2 max levels similar to sedentary young adults.
Why is my VO2 max estimate different from my fitness watch?
Fitness watches use algorithms based on heart rate data and movement patterns, which are indirect measurements. Field tests like this calculator use exercise performance data. Lab tests with gas analysis are most accurate. Different methods can yield variations of 5-15%.
How does HIIT compare to steady-state cardio for improving VO2 max?
Research shows HIIT can be more time-efficient for improving VO2 max, often producing similar or greater improvements with less total training time. However, both methods are effective, and a combination of HIIT and steady-state cardio often produces the best results.
