HOW YOUR FITNESS COMPARES
Understanding your VO₂ fitness classification
Treadmill or stationary bike? These are the two commonly used methods for laboratory VO₂ testing. PhysFitness normally uses a programmable stationary bike because it provides precise workload increments, a stable testing position and repeatable conditions, while avoiding the risk of falling from a moving treadmill. Individual suitability is assessed before testing.
Your VO₂ report will show your actual cycling result and an estimated treadmill-equivalent score to help you compare with people tested on treadmills. This will use age- and sex-specific FRIEND reference data. The treadmill figure is only a population-based estimate, not another measurement or a prediction of your personal treadmill performance. The report will provide a numerical treadmill-equivalent estimate using the same age- and sex-specific FRIEND percentile across testing modalities. For meaningful progress tracking, compare results from the same test type and a similar protocol.
PhysFitness plans to compare your measured VO₂ peak or VO₂ max with published age- and sex-specific reference values from the Fitness Registry and the Importance of Exercise National Database (FRIEND).
FRIEND is a large US research registry of directly measured cardiorespiratory fitness. Its 2022 reference study analysed 22,379 exercise tests across 34 laboratories, providing separate reference values for cycling and treadmill testing.
Our standard assessment is cycle ergometry. Cycling tests will be compared with FRIEND cycling reference data; treadmill tests use treadmill data. Results will be labelled by the percentile and fitness category appropriate to the recorded age, sex reference and test mode.
FRIEND compares fitness with an apparently healthy research population; it is not a diagnosis. Fitness classifications are displayed only for verified measurements with a suitable reference. Expert interpretations are reviewed by staff before publication.
