Why the study?
Aerobic fitness strongly relates to major health outcomes, but because cardiopulmonary exercise testing to directly measure VO2max is not always available, estimation tools are necessary.
Does the CLINIMEX Aerobic Fitness Questionnaire accurately estimate aerobic fitness compared to measured VO2max by CPET in healthy and unhealthy subjects?

The C-AFQ is a simple and valid tool for estimating aerobic fitness when CPET is unavailable, though individual estimation errors can be high.

C-AFQ may estimate METs when CPET unavailable; leaves open prospective validation before routine use.
