A COMPARISON BETWEEN THE VISUAL ANALOGUE AND BORGâ€™S CR10 SCALES FOR PERCEIVED EXERTION
AbstractThe aim of this study was to determine if the visual analogue and Borgâ€™s CR10 scales areefficient for the assessment of perceived general exertion in a ramp continuous dynamicphysical exercise test (RCDPET). The sample was composed of 20 sedentary healthy malevolunteers (18-29 years). The RCDPET was carried out using an electrically brakedcycloergometer (60 rpm), and the scales were asked at the end of each stage. Linearcorrelations were found between the scales, between the scales and oxygen uptake and alsobetween the scales and heart rate values. These results suggest that the physical magnitudesof VAS and Borgâ€™s CR10 scales are highly correlated. Moreover, in both scales, the increaseof power, heart rate and oxygen uptake corresponded to the increase of the participantsâ€™subjective estimations in relation to the physical effort. This may indicate a clear interactionbetween the different variables acting during the RCDPET.
