What it means
VO₂ max is the maximum rate your body can take in and use oxygen — the ceiling on your aerobic engine. This calculator estimates it from your maximal aerobic power (your best 5-minute power, a good proxy for MAP) using the ACSM cycling relationship.
It's an estimate, not a lab test, but it's a useful benchmark to track over a season. VO₂ max responds well to short, hard intervals around Zone 5 (roughly 106–120% of FTP).
