Зміни показників рівноваги тхеквондистів під впливом використання вправ на нестійкій опорі

Abstract

Рurpose: of the study is to track changes in the balance indicators of taekwondo players aged 13-14 under the influence of exercises on unstable support. Material and methods. 8 taekwondo athletes aged 13-14 (4th year of training) participated in the study. To implement the tasks of our research, the following methods were used: to establish the relevance of the topic and select appropriate tests, an analysis of scientific and methodical literature was conducted; to determine balance indicators, Romberg's test was performed on the right and left leg, with eyes open and closed, and a test according to the Yarotskiy method; in order to check the effectiveness of exercises on an unstable support, a pedagogical study was organized and the obtained indicators were analyzed by methods of statistical information processing. Pedagogical testing was conducted remotely through the zoom virtual conference platform for each individual athlete in a separate conference session. Results: indicators of balance development of taekwondo players aged 13-14 have been established at a sufficient level. There was no difference between the performance of balance test exercises on the left and right leg in athletes (at p˃0,05). Performance indicators of the Romberg test while standing on one leg with eyes open are significantly higher than performance of this task with eyes closed (at p˂0,01). After the conducted pedagogical study, the balance indicators of young athletes in almost all test exercises underwent positive changes: the performance indicators of the Romberg test on the right and left leg with open eyes improved by 10,1 % and 7,6 %, respectively (at p˂0,05); with eyes closed improved by 11,6 % when performing the test on the right leg and by 14 % on the left leg (at p˂0,05). The results of the Yarotskiy test in our study had an improvement of 10,8 %, but did not have reliability (at p˃0,05) Conclusions. The suggested exercises of an imitative nature, which are performed on a non-sticky support, have a positive effect on the development of coordination abilities of taekwondo players, in particular, balance.
