INCREASING INDICATORS OF DEVELOPMENT OF FLEXIBILITY AND MOBILITY IN THE JOINTS OF QUALIFIED BASKETBALL PLAYERS OF THE UNIVERSITY SPORTS TEAM

The purpose of the research is selection and practical testing of the arsenal of motor means aimed at improving the indicators of flexibility development and increasing mobility in the joints of qualified basketball players of university sports teams.

Research methods: selection, systematization, analysis and generalization of scientific and methodological and specialized literature, pedagogical experiment, pedagogical testing, methods of mathematical statistics.

Research results and their discussion. In the training process of qualified basketball players, specially selected means for stretching the muscular-ligamentous apparatus of a high-amplitude nature were included in the warm-up and the final part of the classes. At the beginning and at the end of the experiment, the indicators of the development of flexibility and mobility of the joints of basketball players were tested. The analysis of the indicators obtained at the end of the experiment revealed significant changes in both study groups between the results of the initial and control testing. However, after the completion of purposeful pedagogical influence, the studied indicators in the basketball players of the experimental group had a more pronounced positive dynamic character.

Conclusion. Based on the results of the experiment, it can be concluded that the changes in the studied indicators had a positive trend. However, in the experimental group there was a more significant increase in indicators, the range of changes was from 13.7 to 53.7%, and in the control group it was less pronounced – from 2.9 to 28.9%. It follows that the training sessions in the experimental group, including specially selected stretching means of a high-amplitude nature in the warm-up and the final part, were an effective pedagogical direction for influencing the motor sphere of basketball athletes.
