EVALUATION OF PHYSICAL DEVELOPMENT OF ADOLESCENT WRESTLING COMPETITORS’ BASIC MOTOR QUALITIES

The research aimed to establish the level of variability of some major indicators characterizing the physical development of adolescent wrestling competitors’ basic motor qualities. The research was carried out in 2021 with the age group 12-14 years, and the results had to be compared with those obtained from a survey in 2012. The research was done among 22 coaches and wrestling specialists (part of whom are Olympic, World, and European champions) and 79 boys, divided into three age groups as follows: U12 –25, U13 –32, and U14 –22. Sports-pedagogical testing and an interview were used for the purposes of the research, as well as a review of literary sources and their theoretical analysis. The results from the research were processed statistically with Microsoft Office Excel 2016 and IBM SPSS Statistics - v23. We applied the following statistical methods: variation analysis, comparative analysis with Student’s t-criterion, Cohen’s d, Kolmogorov-Smirnov, and Shapiro-Wilk tests. The summary of the data and the analysis made for the three researched groups established variability of some basic indicators characterizing the physical development of basic wrestling qualities. There were three main groups of indicators in the three groups of researched individuals: indicators with low variability, relatively high variability, and very high variability. There was a decrease in the difference in the coefficient of variation in most physical indicators and an improvement in the mean values from U12 to U14. The hypothesis was confirmed that the final results after the surveys held in 2021 would be lower than those obtained in 2012. The obtained data are interesting for the specialists because they enrich training methods with new facts, which are essential for increasing the efficiency of sports preparation in sports clubs and national teams
