Resumo
Objective. The aim of this study was to analyze the relationships between the rate of perceived exertion (RPE) of a whole exercise session (RPE-S) and objective measures of exercise intensity during a karate training session.Methods. Eight well-trained karate athletes performed a single training session involving basic karate techniques and sparring. Heart rate (HR) was continuously monitored, while blood lactate ([lac]13) and rating of perceived exertion using the Borg's 6-20 scale were taken each 10-min during exercise. Athletes were also asked to rate their RPE-S using a modified CR-10 scale 30-min after exercise.Results. Significant relationships (P<0.05) were found between RPE-S and mean values of %HRmax (r(p) = 0.91), %HR reserve (r(p) = 0.87), [lac]b(r(p) = 0.96), and RPE (r(p) = 0.78) during the session, but not between RPE-S and the duration of exercise bout (r(s) = 0.28; P > 0.05). RPE-S was also significantly related (P < 0.05) to percentage of time sustained under ventilatory thresold (VT) (r(p) = 0.96), between VT and respiratory compensation point (RCP) (r(p) = 0.93) and above RCP (r(p) = 0.96).Conclusion. These results suggest RPE-S to be a valid tool for assessing interindividual variations in global exercise intensity during karate training. (C) 2010 Elsevier Masson SAS. All rights reserved.
