Validity of Rating of Perceived Exertion During Graded Exercise Testing in Apparently Healthy Adults and Cardiac Patients
Why the study?
Does the rating of perceived exertion (RPE) accurately reflect relative exercise intensity during graded exercise testing in healthy adults and cardiac patients?

Implication
Substantial RPE variability at moderate intensity cautions against uniform targets; leaves open whether individualized RPE improves exercise prescription in cardiac patients.
Structured PICO
Does the rating of perceived exertion (RPE) accurately reflect relative exercise intensity during graded exercise testing in healthy adults and cardiac patients?
P
Population
680 subjects, including apparently healthy adults (N = 463) and cardiac patients (N = 217) who presented for a sign-symptom limited maximal graded exercise test (SSLMGXT).
I
Intervention
Sign-symptom limited maximal graded exercise test (SSLMGXT) with assessment of rating of perceived exertion (RPE)
O
Outcome
Rating of perceived exertion (RPE) associated with relative exercise intensities of 60% and 80% of maximal heart rate reserve (MHRR) and peak exercisepatient reported
The large interindividual variability in RPE during graded exercise testing challenges the applicability of generalized RPE recommendations in recent exercise guidelines.
