Endurance Capacity Calculator | Measure Athletic Potential

Yes, endurance capacity is highly trainable. Most people can improve their VO₂ max by 15-20% with structured training over 3-6 months. Even elite athletes can see improvements of 5-10% with proper training.

Endurance capacity is your physiological potential, while race fitness includes additional factors like pacing strategy, nutrition, running economy, and sport-specific skills. High endurance capacity is necessary but not sufficient for optimal race performance.

For trained runners, the 1.5-mile test or Cooper 12-minute run typically provides the most accurate results. Cyclists may prefer submaximal tests that allow for sport-specific testing.
