Predicting maximal oxygen uptake from a 3-minute progressive knee-ups and step test

Abstract

In our study, involving Taiwanese adults, we constructed and verified a model to predict V̇O₂ max, which indicates cardiorespiratory fitness. This model had the predictors sex, age, body composition, and heart rate changes during a step test. Our 3MPKS test has the potential to be widely used in epidemiological research to measure V̇O₂ max and other health-related parameters.
