This study investigated tactical-technical performance indicators distinguishing high-level Shotokan Karate athletes. It was an observational, cross-sectional study analyzing match tactics through timing, frequency, concatenation, location, type, and effectivenessof techniques. Participants were 34 male black belts (1st Dan or higher) competing in the XXI Brazilian Championship of the Japan Karate Association (JKA). Match footage was analyzed by a single trained observer with confirmed reliability. Resultsshowed similar trends between finalists and non-finalists in technique frequency, sequence composition, and effectiveness. Significant differences appeared in timing, with more attackers among finalists (p < 0.05, Cramer’s V = 0.39), suggesting an advantage in limiting opponents’ timing. Effective techniques occurred mainly in central and peripheral areas for finalists and non-finalists, respectively. Although both groups favored upper-limb techniques, finalists performed more two-technique sequences.
