A judo fight is an intellectual space because ot the tactics involved in its management. As a fundamental factor, these tactics contribute effectively to performance. This study aimed to calculate, compare and analyse the most frequent and effective tactical actions chosen by male elite athletes. A sample of 112 Olympic medallists, comprising 28 gold, 28 silver and 55 bronze medals, accomplished 3,991 tactical actions in 575 fights at four successive Olympic Games (2004-2016). The Kolmogorov-Smimov test assessed the normality of the collected data. The Levene's test shoæd the equality of variance. ANOVA (one factor) made inter-Olympic (longitudinal Study) and intra-Olympic (cross-sectional study) comparisons, followed by the Post hoc Bonfermni test (p< 005). Eta squared n2 and d of Cohen estimated the erect Size. Olympic medallists performed respectively 74.8±6.9% direct attacks, 9.3±3.8% combination, 7.8±3.3% standing to ground transition, and counterattack. In terrns ofeffectiveness, direct attack 54.1±13.3% dominates ahead of counterattack 15.3±10.1%, combination 14.6±7.5% and standing to ground transition 13.6±8.9% Feint and repeated attacks had a negligible contribution. The offensive system of Olympic medallists is mostly based on direct attacks, but additional options such as counterattack, combination and Standing to ground transition also led to their success The findlngs of this Study could he/p improve the tactical preparation of elite judo athletes.
