Summary 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]b) 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 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 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.
