This dissertation has two goals: developing and evaluating a computer program for the analysis of technical and tactical combat in judo, and analyzing technical-tactical actions used by judo athletes from four age classes (pre-juvenile, juvenile, junior and senior) in the eight official Brazilian weight categories (super-light to heavy), males and female, at two different levels, namely: (1) São Paulo City (Paulistano) and (2) São Paulo State levels. The variables were: i) temporal fight structure, ii) execution and direction of throws, iii) quantification of scores and iv) characterization of grip type. In order to verify the objectivity of the computer program, three experts conducted 20 analyses of combats, with one expert examining three times the same 20 (1st. expert, n = 20; 2nd. expert n = 20; 3rd. expert n = 60). For comparison between groups observed in the second study and in order to verify the concordance correlation (CCC) between experts measurements, analysis of variance and, when necessary, post hoc Tukey test with significance level p <0.05, were used. The results from the software showed strong intra and inter-expert agreement, with higher rate (> 0,90 of index) in 41 groups of variables and (>0,80 of index) in 37 groups of variables, respectively. For the second study, the most significant results from the male group were at the state and/or the senior class, using longer periods of combat, standing fight (tachi-waza), free displacement, grip time and variation in grip type, and direction of attacks. In females, there were differences between state and/or the senior class (except when compared to pre-juvenile in fight time without pause and grip time) and other groups, with more combat time, tachi-waza, free displacement and grip - showing differences between the heavyweight, who presented less combat, tachi-waza, free movement and grip times, and half-lightweight, lightweight and welterweight categories. Regarding differences between levels, state-level athletes used a higher frequency of techniques and different grip types (AU) | |
