Résumé : |
Objective To investigate the utility of the differentiated rating of perceived exertion (RPE) for the self-regulation of submaximal wheelchair propulsion in novice users. Design Each participant completed a submaximal incremental test and a graded test to exhaustion to determine peak oxygen consumption (Vo2peak) on a wheelchair ergometer. On a separate day, two 12-minute intermittent bouts consisting of three 4-minute stages were completed at individualized imposed power outputs equating to light (40% Vo2peak) and moderate (60% Vo2peak) intensity exercise. On a third occasion, participants were assigned to either the overall group or the peripheral group and were required to self-regulate 12-minute intermittent exercise according to either overall RPE or peripheral RPE reported during the corresponding imposed intensity trial. Setting Laboratory facilities at a university. Participants Preliminary population of able-bodied participants with no prior experience of wheelchair propulsion (N=18). Interventions Not applicable. Main Outcome Measures Differences in oxygen consumption (o2), heart rate, blood lactate concentration, and power output between the imposed and self-regulated exercise trials. Results No difference was found in physiological responses between the moderate-intensity imposed and RPE-regulated trials in the peripheral group, whereas a significant (P<.05 underproduction in o2 vs and blood lactate concentration was seen the overall group. contrast a significant overproduction peripheral group at light exercise intensity whereas no difference found between all variables during light-intensity imposed rpe-regulated trials> Conclusions Peripheral RPE enabled a more precise self-regulation during moderate-intensity wheelchair exercise in novice users. In contrast, overall RPE provided a more accurate stimulus when performing light-intensity propulsion. |
