Abstract
Background and Study Aim: Very important changes in judo sport combat regulations were introduced in 2009-2010. The purpose of those changes was to make judo combat more attractive and to eliminate or reduce the techniques which do not derive from the accepted classification of judo techniques (grasping opponent’s legs). The aim of our research was to determine the impact of the new judo rules on the effectiveness of techniques and the results achieved by men’s national judo teams.
Material and Methods: The material comprised 811 judo men’s contests documented by audio-video recorder during the World Championships in Rotterdam (2009), and the World Championships in Tokyo (2010). The fights were described using the graphic method of registration. The most effective teams were determined taking into account medals won and places taken in particular weight categories whereas predominant techniques were described by means of the technical-tactical preparation indices.
Results: Based on the championships results it was determined that during the 2009 World Championships the most effective teams were as follows: Korea, Russia and Ukraine. The predominant throwing techniques were seoi nage, kuchiki taoshi and kosoto gari, and the hand throws group was the most effective. During the 2010 World Champs the order of teams was as follows: Japan, France, Uzbekistan. Seoi nage, uchimata, osoto gari were the most often executed throws; and the leg throws were the most effectively performed.
Conclusions: Diminishing the effectiveness of hand throws (during World Champs 2010): kuchiki taoshi and sukui nage and increase in the effectiveness of leg techniques: kouchi gari, uchimata, osoto gari was close with increase of Japan’s performance (men’s group). Our findings will serve as basis for improving training programmes for judo competitors.
