Aerobic capacity estimate

VO2 max represents your estimated maximum oxygen use during intense exercise and is a key marker of endurance fitness.

Assumptions

Field tests assume maximal effort and steady pacing. Environmental conditions and pacing strategy can affect results.

Track over time

Repeat the same test under similar conditions to compare progress between training blocks.
