What is VO2 Max?

VO2 max (maximal oxygen uptake) is the maximum amount of oxygen your body can utilize during intense exercise. It's considered the gold standard for measuring cardiovascular fitness and aerobic endurance capacity.

VO2 max is important because it:

  • Predicts endurance performance potential
  • Indicates overall cardiovascular health
  • Helps design effective training programs
  • Provides motivation for fitness improvement

Estimate Your VO2 Max

Use our VO2 max estimator to get an accurate assessment of your cardiovascular fitness level based on your performance in various fitness tests.

VO2 Max Estimation Methods

Cooper 12-Minute Run Test

Run as far as possible in 12 minutes on a track or treadmill

Good for runners
VO2 Max = (Distance in meters - 504.9) / 44.73

Rockport Walking Test

Walk 1 mile as fast as possible and record heart rate

Good for all fitness levels
VO2 Max = 132.853 - (0.0769 × weight) - (0.3877 × age) + (6.315 × gender) - (3.2649 × time) - (0.1565 × HR)

Queens College Step Test

Step up and down on a 16-inch step for 3 minutes

Good for beginners
VO2 Max = 111.33 - (0.42 × HR)

Factors That Affect VO2 Max

Genetics

High

Your genetic potential sets the upper limit for VO2 max

Training

Very High

Regular aerobic exercise can improve VO2 max by 15-25%

Age

Moderate

VO2 max naturally declines about 1% per year after age 30

Body Composition

Moderate

Lower body fat percentage generally correlates with higher VO2 max

How to Improve Your VO2 Max

High-Intensity Interval Training (HIIT)

Alternate between high-intensity bursts and recovery periods

2-3 times per week•20-30 minutes
Increases VO2 max
Improves lactate threshold
Burns more calories

Long Slow Distance (LSD)

Sustained moderate-intensity exercise for extended periods

1-2 times per week•45-90 minutes
Builds aerobic base
Improves fat burning
Enhances endurance

Tempo Training

Exercise at lactate threshold intensity

1-2 times per week•20-40 minutes
Raises lactate threshold
Improves race pace
Builds mental toughness

Fartlek Training

Unstructured speed play with varying intensities

1 time per week•30-45 minutes
Improves VO2 max
Adds variety
Fun and engaging
