Face scale rating of perceived exertion during cardiopulmonary exercise test

ObjectiveThis study aimed to investigate the correlation between the face scale and heart rate (HR), exercise load and oxygen uptake (V̇O2) during cardiopulmonary exercise testing. Methods This was a prospective, observational study of face scale rating of perceived exertion (RPE) and HR, exercise load and V̇O2 during cardiopulmonary exercise testing. A total of 30 healthy college men and 21 healthy college women were included. Subjects performed a cardiopulmonary exercise test with ramps and an increment increase in workload of 20 W/min. We recorded the responses of subjects using a face scale for RPE, HR, exercise load and V̇O2 every minute during the cardiopulmonary exercise test.ResultsIn men, there was a significant positive correlation between the face scale RPE and HR (ρ=0.856, p
