Abstract

OMNI ratings of perceived exertion (RPE) and physiological responses in children (n=7 boys, 8 girls, 11.1±1.0 years) were examined during estimation (graded exercise test [GXT] and steady-state) and production (steady-state) trials on a cycle ergometer. Peak oxygen consumption (VO2peak) was determined via a GXT with RPE estimated every 30 s. Later, two 6-min trials were completed: Participants 1) estimated RPE at ~75% of VO2peak, 2) produced a level of exertion corresponding to their RPE at ~75% of VO2peak during the GXT. Data analysis included a one-way MANOVA and a paired t-test. The target intensity during the GXT corresponded to 74.2±2.5% of VO2peak; the steady-state estimation and production trials were performed at 76.5±2.7% and 68.5±14.1% of VO2peak, respectively (p>0.05). Mean RPE at ~75% of VO2peak during the GXT and production trial was 6.7±1.5; during the steady-state estimation trial RPE was 5.8±2.0 (p>0.05). There were no differences (p>0.05) in the physiological responses. Participants estimated RPE similarly at ~75% of VO2peak during both graded and steady-state exercise, but when asked to produce a given RPE, marked variability was observed in physiological responses. These findings may have implications in optimizing exercise prescriptions for children.
