VO₂ Max Calculator
Estimate your maximum oxygen uptake (VO₂ max) based on running performance. VO₂ max is the gold standard measure of cardiovascular fitness and aerobic capacity, crucial for endurance performance and health assessment.
Your VO₂ Max
How to Use the VO₂ Max Calculator
1. Enter recent race performance: Input your distance and time from a recent race or time trial where you gave maximum effort. Use performances from the last 2-3 months for accuracy.
2. Choose appropriate distance: VO₂ max calculations are most accurate using race times from 1500m to 10K distances, where aerobic capacity is the primary limiting factor.
3. Review your VO₂ max estimate: The result shows your estimated maximum oxygen uptake in ml/kg/min, the standard unit for measuring aerobic fitness.
4. Compare and track progress: Use age and gender norms to understand your fitness level and track improvements over time with consistent testing.
Understanding VO₂ Max
VO₂ max represents the maximum amount of oxygen your body can utilize during intense exercise, measured in milliliters of oxygen consumed per kilogram of body weight per minute (ml/kg/min).
What VO₂ Max Measures
- Cardiovascular efficiency: Heart's ability to pump oxygenated blood
- Lung capacity: Oxygen uptake and carbon dioxide removal
- Muscle efficiency: Ability to extract and use oxygen from blood
- Overall fitness: Integrated measure of aerobic fitness systems
Factors Affecting VO₂ Max
- Genetics: 40-50% of VO₂ max is genetically determined
- Training: Aerobic exercise can improve VO₂ max by 15-25%
- Age: Typically declines 1% per year after age 30
- Body composition: Lower body fat generally correlates with higher VO₂ max
VO₂ Max Fitness Categories
Compare your VO₂ max to age and gender-specific norms to understand your cardiovascular fitness level:
Men (ml/kg/min)
Women (ml/kg/min)
How to Improve Your VO₂ Max
Targeted training can significantly improve your VO₂ max and overall cardiovascular fitness:
High-Intensity Training
- VO₂ max intervals: 3-8 minute intervals at 90-95% max heart rate
- 5K pace training: Sustained efforts at your 5K race pace
- Hill repeats: Short, steep climbs to stress the aerobic system
- Fartlek training: Varied pace runs with speed surges
Base Building
- Easy aerobic runs: 70-80% of training at conversational pace
- Long runs: Extended efforts to build aerobic capacity
- Tempo runs: Sustained efforts at lactate threshold pace
- Cross-training: Cycling, swimming, or rowing for variety
Training tip: Use our training paces calculator to determine optimal intensities for VO₂ max development based on your current fitness level.
