Abstract
This study assessed the validity of the Eston‐Parfitt (E‐P) curvilinear Ratings of Perceived Exertion (RPE) Scale and a novel marble quantity task to provide estimates of perceived exertion during cycle ergometry. Fifteen children aged 7–8 years performed a discontinuous incremental graded‐exercise test, and reported exertional ratings at the end of each minute. Significant increases in physiological and perceptual data were observed with increasing work rate. The relationship between work rate and marbles was curvilinear (mean R2=.94), supporting the theoretical justification for the E‐P Scale. Strong linear (R2=.93) and curvilinear (R2=.94) relationships between RPE from the E‐P Scale and work rate confirmed the robustness of the E‐P Scale. Valid exertional ratings may be obtained using the E‐P Scale with young children. The novel marble quantity task offers an alternative method of deriving perceived exertion responses in children.
