VO2 max is the maximum rate of oxygen use during intense exercise, usually expressed as milliliters of oxygen per kilogram of body mass per minute. Higher values generally reflect stronger cardiorespiratory fitness, but interpretation depends on age, reference sex, test method, and whether the value is measured in a lab or estimated by a wearable.
A good VO2 max is not one universal number. The same 44 ml/kg/min can be good for one adult cohort and fair or excellent for another. Age decade and reference sex change the published thresholds, so a useful lookup must keep those categories visible.
This reference is informational. It is not a diagnosis, treatment plan, race prediction, or medical clearance. Health conditions, medications, altitude, device algorithms, and test protocol can all affect the value.
Technical Details:
The lookup uses adult age cohorts from 20 to 79 and two reference-sex tables. Each cohort has threshold floors for Fair, Good, Excellent, and Superior. Poor is below the Fair floor. The Good band starts at the 60th percentile floor and ends just below the Excellent floor at the 80th percentile.
| Band | Lower boundary | Upper boundary | Meaning in this lookup |
|---|---|---|---|
| Poor | Below Fair floor | Fair floor, exclusive | Below the 40th percentile floor |
| Fair | Fair floor, inclusive | Good floor, exclusive | 40th to 59th percentile band |
| Good | Good floor, inclusive | Excellent floor, exclusive | 60th to 79th percentile band |
| Excellent | Excellent floor, inclusive | Superior floor, exclusive | 80th to 94th percentile band |
| Superior | Superior floor, inclusive | No upper cap | 95th percentile and above |
Age is rounded to a whole year and mapped to a decade cohort, not interpolated year by year. Decimal places control display rounding only; the underlying threshold values remain the table values. An optional measured VO2 max is classified against the selected cohort and produces a next-tier gap when the value is below the next band.
Everyday Use & Decision Guide:
Enter age first, then choose the reference sex that matches the table you want to compare against. Add a measured VO2 max only if you have a lab value, watch estimate, field-test estimate, or coaching report in ml/kg/min.
The Good VO2 Band tab answers the narrow question: what range counts as good for this cohort? The VO2 Rating Table shows all bands for the same cohort, and VO2 Rating Ladder helps compare the selected cohort against other age bands.
- Use Good floor and Excellent floor to understand the good range.
- Use Measured rating only when the optional measured value is entered.
- Check warnings if the measured value is unusually low or high.
- Do not compare a wearable estimate with a lab test as if they used the same protocol.
A value above the good floor does not mean training is safe or sufficient for every person. Symptoms, medical history, and training goals still matter.
Step-by-Step Guide:
- Enter Age from 20 to 79 years. If the error says the cohort is unavailable, use an age inside the supported adult range.
- Select Reference sex to load the male or female threshold table.
- Open Advanced if you want to enter Measured VO2 max or adjust Decimals.
- Read Good VO2 Band for the good range and the floor values shown in the summary badges.
- Use VO2 Rating Table, VO2 Reading Guide, VO2 Rating Ladder, or JSON for deeper review.
Interpreting Results:
The most important value is Good VO2 max band, displayed in ml/kg/min. The lower number is the Good floor. The upper value is exclusive because the Excellent band starts there.
Do not overread small changes near a boundary. If a measured value is 43.9 and the Good floor is 44.0, rounding, device error, or test-day conditions may matter more than the one-decimal difference. Recheck the source unit and repeat comparable tests before changing training plans.
Worked Examples:
A 35-year-old male maps to the 30-39 male cohort. The good band is 44.0 to below 48.3 ml/kg/min. A measured value of 44.0 is Good; 43.9 remains Fair by the displayed boundary.
A 52-year-old female maps to the 50-59 female cohort. Good starts at 33.0 and Excellent starts at 36.7, so a measured value of 36.7 is Excellent, not Good.
If age 82 is entered, the lookup shows an error because the reference tables cover adult cohorts from 20 to 79 years only.
FAQ:
Why does age use decade cohorts?
The reference table is published in decade bands from 20-29 through 70-79. The lookup maps the entered age to the matching cohort rather than interpolating between rows.
What unit should I enter for a measured value?
Use ml/kg/min. If the warning says the value looks unusually high or low, confirm the source and unit before using the measured rating.
Does good mean healthy?
No. The band is a reference category for cardiorespiratory fitness comparison. It is not a diagnosis or a medical clearance.
Why do watch estimates differ from lab tests?
Wearables estimate VO2 max from indirect signals and device algorithms, while lab tests measure oxygen use under a controlled protocol. Compare repeated values from the same method when possible.
