ABSTRACT
The objective was to compare the objectivity and to verify the applicability of computational time-motion analysis (TMA) and technical-tactical analysis of judo for different levels of expertise. The sample was composed by 22 subjects (12 practitioners, separated into six experts and six non-experts, and 10 non-practitioners). The sample qualified the software via questionnaire and they conducted 150 analysis (90 = inter-group comparisons; 60 = intra-group comparisons). Data were compared by Wilcoxon and Friedman, and by Kappa Cohen coefficient, p <0.05. No differences were observed between groups when compared the quality indicators, which showed better percentage in response "all the time", when compared with the responses "most of the time", "part time" and "never or not" (p <0.001 ). The correlations showed "strong" concordance (index = 0.76) in TMA for the three groups, but a "weak" agreement (index = 0.08) of technical-tactical analysis between practitioners and non-practitioners. In conclusion, TMA presented replicability in the three groups; for technical-tactical analysis it is required a specific knowledge of judo.
