Prediction of peak oxygen uptake from ratings of perceived exertion during a sub-maximal cardiopulmonary exercise test in patients with chronic obstructive pulmonary disease

摘要

We assessed the validity of predicting peak oxygen uptake (O-2 peak) from the relationship between oxygen uptake (O-2) and overall ratings of perceived exertion (RPE) obtained during the initial stages of a cardiopulmonary exercise test (CPET).
