Abstract
This study evaluated the effectiveness of the Ippon Seoinage technique in judokas participating in the National Prejuvenile Games. Frequency of application, success rate (Ippon and derived scores), technical efficiency, and relationships with biomechanical, tactical, and contextual variables were analyzed. The sample included 10 judokas in a pretest-posttest design. Data were processed using SPSS v25 with descriptive statistics, paired t-tests, and Pearson correlation analysis. Results showed significant improvements in usage frequency (pretest: 1.4; posttest: 2.9; p < 0.01), success rate (pretest: 20.5%; posttest: 48%; p < 0.01), and technical efficiency (pretest: 5.1; posttest: 7.8; p < 0.01). Increases in angular velocity and decreases in execution time indicated enhanced biomechanical effectiveness. Qualitative analysis also revealed improved tactical perception in the posttest. Findings suggest that specific training enhances execution and effectiveness of Ippon Seoinage in youth categories, providing valuable evidence to optimize judo athlete development.
