Introduction. This study aims (1) to determine the effects of Kata Karate Goju-Ryu training on heart rate (HR), blood lactate ([Lac]) and rating of perceived exertion (RPE), and (2) to clarify the association between RPE, HR and [Lac] on response to Kata training. Material and methods. The sample was composed by 36 Kata performances, which were done by six male athletes. The assessments included anthropometric measures (age, 37±13 yrs.; stature, 1.81±0.07 m; body mass, 77.20±7.64 kg; fat mass, 24.72±6.79%) and the following physiological indicators: HR, intensity [(HRtraining – HRbasal) / (HRmax – HRbasal)], [Lac] and delta lactate (Δ[Lac]). The RPE was assessed after each Kata using the original version of Borg’s 15-category scale (RPE6-20) and after 30-minutes of the Kata training using the modified Borg’s Category-Ratio (RPECR-10) scale. Results. In spite of the results indicated a moderate metabolic rate of the Kata training (HRmax, 71.49%), with no significant differences between Kata. Mooreover, the both RPE Scale were not associated with effort intensity, [Lac] and Δ[Lac] (except for RPECR-10 on the second and the fifth Kata). Conclusions. The variability of the actions of the Goju-Ryu Karate Kata makes the aerobic metabolism the predominant source, what explain why the RPE6-20 was associated with effort intensity in trials, except on the second and the fifth Kata.
