The aim of this research was to determine the effects that specific preliminary exercises have on the quality of knowledge and the performance techniques in judo. The quality with which the techniques were performed was studied for ten techniques. The research was carried out on a sample 224 students, all from the Internal Affairs High School in Sremska Kamenica, who, during the 2003/04 school year, had three judo classes a week. The basic problem that arises in learning judo techniques is that the qualitative characteristics of movement, self-movement and movement used to exemplify the learned techniques should be improved at the same time the techniques are being acquired. The experimental factor, consisting of 50 special preliminary exercises, was used on the experimental group. The control group studied judo techniques in the standard (traditional) manner. The experiment lasted for the duration of one school year. The qualitative characteristics of the presented techniques were evaluated by five experts. The results of this research have indicated that the application of specific preliminary exercises affected the process of determining the significant statistical difference in the quality of movement and motion in five of the ten studied judo techniques. At the end of the experiment, the execution of five techniques on the part of the subjects of the experimental group was given a better evaluation in comparison to the execution of the techniques on the part of the subjects of the control group. This in turn proved the effect of the experimental factor, the specific preliminary exercises.
