MILANEZ, Vinicius Flávio and PEDRO, Rafael Evangelista. Application of different load quantification methods during a karate training session. Rev Bras Med Esporte [online]. 2012, vol.18, n.4, pp. 278-282. ISSN 1517-8692. http://dx.doi.org/10.1590/S1517-86922012000400012.
The subjective ratings of perceived exertion (RPE) of the session have stood out among the methods of load training quantification (LTQ) in some modalities, mainly due to their low cost and easy applicability. However, there are no reports in the literature on their application in the karate modality. The aim of this study was to analyze the relationship between RPE session with Banister TRIMP , Edwards TL , Lucia TRIMP, Stagno TRIMP and Lac TRIMP. Eight well-trained athletes of both sexes (21.6 ± 5.5 years; 58.8 ± 13.8 weight; 170.0 ± 0.11 height) performed a single training session with continuous heart rate monitoring, blood lactate collections every 10 min and RPE quantification through the CR-10 scale, 30 min after the end of the training, for subsequent calculation of training impulse. Significant correlations (P<0.05) were found between RPE session and Banister TRIMP (r = 0.79), Edward TL (r = 0.81), Lucia TRIMP (r = 0.71), Stagno TRIMP (r = 0.71) and Lac TRIMP (r = 0.91). Thus, the results of this study suggest the RPE session as an efficient method from the LTQ in shotokan karate athletes.
