Abstract

This experiment tested whether the conformism observed among panels of judges in aesthetic sports also occurs among judges in judo. Similar to aesthetic sports, judo judging relies upon a form of open feedback. However, in judo, this system is reactive (i.e. two judges have to publicly 'correct' the score given by the higher-status referee), whereas it is active in aesthetic sports (i.e. judges with equal status report their score simultaneously and can use the feedback about the scores of their colleagues for evaluating later performances). In order to test whether such reactive open-feedback system leads to conformism among judges in judo, we designed an experiment in which this feedback was manipulated. Participants were 20 certified Flemish judges, who had to score two sets of 11 ambiguous video sequences that are used during formation and training of judo judges: one set with feedback about the referee's score and one set without feedback. The results revealed that when participants knew the referee's score, their scores were significantly more in line with this score than when they did not know this score. More specifically, for both sets of sequences at least 10% less deviations from the referee were observed when participants were given feedback about the score of the referee. These results suggest that preventable conformism can occur in typical judo judging, that is with reactive open feedback.

Análise de lutas de TKD dos Jogos Asiáticos


ABSTRACT
Kwok HHM. Discrepancies in fighting strategies between Taekwondo medalists and non-medalists. J. Hum.
Sport Exerc. Vol. 7, No. 4, pp. 806-814, 2012. The aim of this study was to compare the fighting strategies
between medalists and non-medalists in Taekwondo. A total of 107 matches from the 16th Asian Games
had been video-taped for notational analysis. Round house kick was the most frequently used kick by the
medalists in the competition (63.29%) while cut down kick (9.26%) and push kick (7.08%) were ranked
second and third respectively. Aggressive mode of attack was the dominant fighting strategy used by the
medalists (63.17%).  Discrepancies in fighting strategies between Taekwondo medalists and non-medalists
were found in this study including mode of attack, use of turning attack, and number of types of kick
employed.
Key words: MARTIAL ARTS, NOTATIONAL ANALYSIS, ATTACK.

A FIJ não apoia os métodos duros de treinamento

Eu apoio métodos duros de treinamento; não apoio é espancar os atletas...


The IJF Condemns Hard Training Methods

31th January 2013.


In direct connection with the complaint of a group of athletes from the national Japanese women's team, reporting the acts from their coach, the IJF strongly emphasizes its total disapproval of such behaviors.
"It has nothing to do with the spirit and philosophy of judo taught by the founding master of our sport, Master Jigoro Kano," said the President of the International Judo Federation, Mr. Marius Vizer.
 
The IJF is particularly focussed on the development and promotion of the moral code of judo. Judo is a method to develop the physical and mental capacities, whose primary concern is to maintain the health and integrity (physical and mental) of the participants. Any action that goes against these principles are banned. The IJF will therefore take all necessary measures.

La FIJ désapprouve les méthodes durs d'Entraînement
En lien direct avec la plainte portée par un groupe d'athlètes de la sélection nationale japonaise féminine, concernant les agissements de la part de leur coach, la FIJ tient à fortement souligner sa totale désapprobation envers de tels comportements. "Ceux-ci n'ont rien à voir avec l'esprit du judo et la philosophie enseignée par le maître fondateur de notre sport, Jigoro Kano", déclare le Président de la Fédération Internationale de Judo, M. Marius Vizer.
 
La FIJ met particulièrement l'accent sur le développement et sur la promotion du code moral du judo. Le judo est un moyen d'éducation physique et mental dont le souci premier est de préserver la santé et l'intégrité (physique et mentale) de ses pratiquants. Toute action qui va contre ces principes est bannie. La FIJ va par conséquent prendre toutes les mesures qui s'imposent.

Judocas del equipo olímpico japonés fueron golpeadas con sables de bambú por su entrenador

El mundo del judo japonés está conmocionado tras conocerse que las componentes del equipo olímpico femenino eran maltratadas regularmente por su entrenador, que las golpeaba con sables de bambú y las aboteteaba.
El escándalo saltó después de que 15 jóvenes se decidieran a denunciar el mes pasado la manera de actuar de su entrenador ante el Comité Olímpico Japonés (COJ).
Las judocas, algunas de las cuales participaron en los Juegos Olímpicos de Londres-2012, acusaron a su entrenador Ryuji Sonoda de abofetearles y de golpearles con sables de bambú como los utilizados en la práctica del kendo, una modalidad de arte marcial.
“Hemos solicitado a la Federación Japonesa de Judo que investigue y tomar las medidas necesarias si se confirman los hechos”, declaró este miércoles un responsable del COJ.
El presidente de la Federación de Judo, Koshi Onozawa aseguró que Sonoda y otros entrenadores admitieron los hechos y que fueron advertidos por el organismo.
“El pasado mes de septiembre, recibimos informaciones sobre el hecho de que Sonoda hubiese podido maltratar físicamente a sus atletas. Le interrogamos, al igual que a las deportistas, y se demostró que las acusaciones estaban fundadas”, declaró Onozawa en conferencia de prensa.
Los agresores fueron advertidos por la federación, pero no suspendidos, y amenazados con “sanciones más fuertes si se repetían tales hechos”, añadió Onozawa.
Estas informaciones se conocen semanas después del suicidio de un estudiante que era regularmente maltratado por su entrenador de básquetbol.
Según un informe publicado en enero de 2011, cada año mueren en Japón cuatro niños durante los entrenamientos de judo.
