- Análisis del tipo de técnicas, puntuaciones y sanciones en el Campeonato de Europa de Judo SeniorPublication . Silva Batista, Marco Alexandre; Escobar-Molina, Raquel; Fernandes, Jorge; Louro, HugoIntroducción: El judo es un deporte de combate olímpico dividido en categorías de peso y sexo. Los combates tienen una duración de cuatro minutos en ambos sexos, y cuando las puntuaciones o amonestaciones para ambos competidores son las mismas, se produce empate entre los judocas y el combate se decide mediante la Técnica de Oro. Es por ello que, la duración de los combates y de la competición, puede tener repercusiones en los judocas, tanto desde el punto de vista técnico, táctico, físico, fisiológico y psicológico, entre otros. Objetivo: El estudio tuvo como propósito determinar el predominio de las acciones técnicas, puntuaciones y penalizaciones en función de la duración del combate y la fase de la competición en el Campeonato de Europa de Judo Senior 2021. Metodología: Se observaron 398 combates en todas las categorías de peso y en ambos sexos (230 hombres y 168 mujeres). Para el registro de las técnicas se utilizó la clasificación Kodokan de judo. Se anotaron las puntuaciones y penalizaciones, a lo largo del combate y durante la Técnica de Oro, en las distintas fases de la competición. Resultados: La mayoría de los combates terminaron en el tiempo reglamentario (79,15%) y un menor porcentaje se resolvieron en la Técnica de Oro (20,85%). A medida que se avanza en la fase de competición hay una tendencia a que los combates se decidan mediante la Técnica de Oro. Conclusiones: El tiempo de combate y la fase de competición influyen tant o en el tipo de técnicas empleadas, las puntuaciones obtenidas y las penalizaciones recibidas.
- Biomechanical analysis of technical actions used in the 2021 European Judo Championship – Behavioral Patterns And Effectiveness.Publication . Batista, Marco; Fernandes, Jorge; Louro, Hugo Gonçalo Duarte; Escobar Molina, RaquelIn Judo, each motor action depends greatly on the behavioural and technical variability of each judoka, which largely determines the options and the predominance of biomechanical actions inherent to the movements themselves. The objective was to biomechanically analyse the technical actions used in the 2021 European Judo Championships based on combat time and gold score and verify the effectiveness of these same technical actions both genders. The study sample focused on 400 combats of the European Judo Championship 2021. We used an observation system created for this purpose, according to the classification system proposed by Sacripanti. Cross-frequency tables were produced, where the association degree between variables was analysed using the Chi Square test, where the significance level was set at p ≤ 0.05. We complemented the association analysis between variables by calculating the adjusted standardized residuals. In both genders and phases of combat, the use of binary techniques predominated over lever techniques, with the hierarchy of technical resources used by judokas being identical. In golden score, women showed a significant association with the use of trunk-leg binary techniques. Throughout the fights, women registered differences in the use of groups of techniques. The trunk-leg binary and minimum arm lever techniques revealed significant effectiveness in both phases of combat in both the male and female categories.
- Predominance of techniques analysis used in the final rounds of judo international competitions scoring for the Olympic ranking: A biomechanical approachPublication . Batista, Marco; Sequeira, Diogo; Gancho, Henrique; Fernandes, JorgeJudo is an Olympic combat sport that is divided into male and female weight categories. Each weight category implies significant differences in technical and strategic dimensions, as well as physiological, performance, and body composition among competitors. This individual variability can widely mark options and predominance of biomechanical actions inherent to its own movements. This study aimed to determine the technical actions predominance used by judokas in the international competitions final stages scoring for the Olympic ranking. We observed 285 judo matches, in several weight categories for men and women, played in the final stages of six scoring international competitions for the Olympic ranking in Tokyo 2021. An observation system was used according to the biomechanical classification of judo techniques proposed by Sacripanti. In Nage-Waza combat, there was a predominance of lever techniques over couple techniques. In Ne-Waza there was a predominance of pressure techniques, followed by venous breathing block and dislocation of the elbow joint. There were also differences between genders and significant associations by weight category in the technical options in combat, as well as according to the combat phase.
