This study examined overall, leg, and chest ratings of perceived exertion (RPE) in 16 children (10.7 ± 0.8 yr) and 16 adults (24.2 ± 1.8 yr) during 16 min of exercise performed at an intensity equal to ventilatory threshold (~64% of V̇O 2 max for the children and 61% of V̇O 2 max for the adults). Physiological and perceptual responses were measured at 8 and 16 min. RPE in the children ranged from 11.6 ± 2.3 (chest) to 12.6 ± 2.6 (leg) at 8 min, and from 13.3 ± 2.8 (chest) to 15.1 ± 2.9 (leg) at 16 min. In adults, RPE ranged from 10.9 ± 1.9 (chest) to 12.0 ± 1.8 (leg) at 8 min, and from 11.8 ± 2.1 (chest) to 13.3 ± 1.6 (leg) at 16 min. Between groups, RPE tended to be higher and increased more over time in the children compared to the adults ( P < .08). RPE at 8 min was less than RPE at 16 min, and overall and leg RPE were greater than chest RPE. Children were able to discriminate sensory information arising from different physiological variables; however, the specific physiological cues underlying the perception of effort remains uncertain in this age group.
