Evaluating the Coordination of Motor Abilities in Greco-Roman Wrestlers by Computer Testing

Purpose. The aim of this study was to evaluate, by using a number of selected criteria, the accuracy of Vienna Test System (VST) computer tests used in wrestling to evaluate motor skill development. Methods. Fifteen 16-17-year-old students from the SMS Sports School in Radom, Poland, who had been practising Greco-Roman wrestling for a period of 3 to 6 years took part in a VTS-based examination that measured coordination of motor abilities (CMA). Test reliability and validity were evaluated on the basis of thirty test scores characterising six abilities that define motor coordination. Reliability was defined by performing the tests twice (test/retest) over a period of three-to-five days. The validity of the selected scores was established with the help of three different criteria. Results. Thirteen out of the thirty CMA scores under investigation demonstrated sufficient coefficients of reliability. The CMA tests assessing quick reaction time, frequency of movements, partial spatial orientation, movement adaptability and movement coupling fulfilled the assumed criterion. In most cases, the coefficients of validity were not lower than 0.3. The highest validity level was demonstrated by scores measuring movement coupling, complex reaction time, spatial orientation and movement adaptability, while the lowest one was found in simple reactions and frequency of movements. Conclusions. The obtained reliability and validity coefficients of the scores based on complex reaction, partial spatial orientation, movement adaptability and movement coupling confirm the usefulness of these specific tests in diagnosing CMA in wrestlers, as they meet the demands of sports metrology.

Introduction. The aim of this study was to test the hypothesis that different approaches to the training process in the selfdefense and martial arts, reflected the hierarchical structure of the basic activities of a coach. Materials and methods. Opinions of 159 trainers with many years of experience in capoeira (n=16), taekwon-do ITF version (n=95) and wrestling (n=48) were collected. Diagnostic survey method was used, and the instrument was a questionnaire developed by Tumanian [7] and modified by Januszewski and Sterkowicz [8]. Results. Capoeira and wrestling trainers did not agree as to the status of any of the 20 coach's activities. The biggest differences were in assessing the significance of instructing trainees during competitions, developing planning process and first aid giving. Rsp ranks correlation coefficient = 0.66, p<0.01. Capoeira and taekwon-do coaches had consistent opinions in case of five activities. The largest differences occurred in terms of organizing and judging the competition and instructing trainees during competitions. Rsp rank correlation coefficient = 0.50, p<0.05. The opinions of taekwon-do and wrestling coaches were in line for two activities and the two activities were given different ranks. Rsp rank correlation coefficient = 0.71, p<0.001. Conclusions. Managing technical and physical preparation of trainees, as well as their training process and body control, were the most important activities of a coach in three combat variations. Scientific-methodical research was considered unimportant. None of the surveyed coaches agreed with others on the importance of professional activities, and their rank does not differentiate representatives of the three types of combat.
