The goal of this research was to determine influence of systematical judo practice on morphological and motor characteristics of young students. The sample of this ex-post- factor research included 25 judokas of approximate age of 8.52 years and 32 non-athletes with approximate age of 8.59 years. Morphological and motor characteristic of the students exposed to certain influence of practicing judo were compared to morphological and motor characteristic of those young students who are not exposed to any kind of practicing influence and are marked as non-athletes. For evaluation three variables were observed morphological characteristic and five for motor characteristics. Two-way T-test for small independent groups was used for testing arithmetic mean differences between groups in the individual variables. The results of the analysis indicated that, as for morphological characteristics, there is a significant difference between judokas group and non-athletes group in height. As for motor characteristics there is a significant difference between these two groups in the following variables: velocity strength, repetitive strength and agility, while there were no statistically significant differences for strong stamina and flexibility. The acquired results can be explained by genetic condition of the observed variables at young school ages, as well as with the fact that some of the school children from the judo group were relatively shortly exposed to the training influence. Besides, some of the school children from the non-athletes group practice some other sport but during the test they were not members of any sport team or sport club. Verf.-Referat
