Abstract

Motor coordination, a uniquely important and, at the same time, the least studied element of selection, may be regarded as a very difficult research problem. The purpose of the study was to test the following hypotheses: 1. Motor coordination level undergoes changes during various periods of training; 2. Each sport ist characterized by different level of motor coordination; 3. Motor coordination decreases as the effect of training load. 246 national team members in seven sports disciplines were studied using different methods, the main of which was measurement of rotary coordination, designed by the author. The first hypothesis was fully confirmed. In the majority of kayakers (model discipline) the coordination level was improved during the competition period, as compared with the preparatory period. The second hypothesis was also confirmed. Rotary coordination measurement permitted to differentiate the athletes in seven sports disciplines. A preliminary classification of sports disciplines, according to the level of difficulty, was prepared, with some recommendations for sports selection. The third hypothesis was partly confirmed: decrease of the coordination level depends on the workload and its adequacy to the athletes present capacity. Verf.-Referat
