Background: During a many-year training process, judo competitors are taught new throws and grappling elements. Many competitors can demonstrate a variety of techniques, and execute them during training contests. However, while taking part in sport competition, they are able to execute successfully just a few techniques which will bring them victories in judo matches. Judo coaches and their competitors are trying to extend the variety of techniques which particular competitor can use in the judo competitions. In this paper it has been attempted to determine the efficiency of attacks and the range of executed techniques which were successfully used by the top judo athletes during judo competitions. The aim of this research was to determine the types of executed judo elements as well as to assess the efficiency of their performance. Material and methods: The analysis of the judo contests of the three Polish athletes, ranked among the World's best judo competitors, has been carried out. In the period of two-year preparation for the Olympic Games in Barcelona, all the successful attacks, performed during 251 contests from 68 judo tournaments have been recorded. Assessing the efficiency of throws and grappling techniques, the method of determination of the efficiency of attack -„Sa" has been used. Results/Conclusions: On the ground of the obtained data, we were able to distinguish four groups of techniques which had the different „Sa" values. Those „Sa" values allowed us to determine two groups: „basic" and „auxiliary", which we call individual techniques or „tokui waza" („favourite techniques"). The other groups of techniques we call „situational" and „at random" or „occasional"; and low values of both these groups did not affect the achieved sport results. The process of the judo training can be improved by permanent control of the efficiency of the performed attacks. [ABSTRACT FROM AUTHOR] |
