About VO2max Percentile

VO₂max is the maximal rate at which oxygen can be taken up, transported, and utilized during exercise. It is one of the principal measures of cardiorespiratory fitness.

A percentile rank describes how an individual's measured VO₂max compares with a reference population of the same sex and age group. A higher percentile generally indicates a higher level of cardiorespiratory fitness relative to the reference population.

The FRIEND registry published age-, sex-, and exercise-modality-specific reference standards from directly measured cardiopulmonary exercise testing. However, the percentile anchor values currently embedded in this calculator are a partial table and have not been verified as a complete transcription of the published FRIEND 2022 standards.

The result should be interpreted in the context of the testing protocol, exercise modality, clinical condition, and quality of the cardiopulmonary exercise test.

Important: Results are provisional because the embedded reference table is incomplete. Do not use the displayed percentile for clinical decisions until the reference data are checked against the complete publication tables. This tool should not be used as a substitute for clinical assessment. VO₂max values estimated by consumer wearable devices may not be directly comparable with values obtained from maximal cardiopulmonary exercise testing.
