Зміни показників координаційних здібностей волейболісток під впливом вправ з використанням півсфери BOSU

The changes in indicators of female volleyball players’ coordination abilities under the influence of a set of exercises using a half-ball BOSU are researched in the article. The higher the level of development of coordination of movements is, the wider and more diverse the range of motor capabilities of female volleyball players is, and the more confidently they possess the motor apparatus, which makes it possible to perform corresponding game actions quickly, accurately and timely. Purpose: to test the effectiveness of the use of BOSU hemisphere exercises in order to improve the coordination abilities of volleyball players of the first league team of Ukraine. Material and methods. The following methods were used during the research: analysis of scientific and methodical literature; pedagogical experiment; pedagogical testing; and methods of mathematical statistics. A sequential pedagogical experiment was conducted, which was aimed at improving the coordination abilities of 12 female volleyball players aged 18-22 years of the team “Polisyanka” in Zhitomyr, which takes part in the championship among women’s teams of the first league of Ukraine Dmart. Results. The results of pedagogical testing showed that after the use of the proposed complex of exercises with a half-ball BOSU in training of the team “Polisyanka”, the indicators of all conducted tests of female volleyball players significantly improved in comparison with the results of the corresponding tests obtained before the experiment. The greatest increase in absolute value was obtained by the calculated values of indicators of the test “Balance test on one leg on a half-ball BOSU” – 45,3% and the test “Passing the ball from below with both hands for accuracy” – 29,0% the lowest increase was obtained by the result of the test ‘Running with tasks’ - at the level of 9.2% compared to the results of the corresponding tests obtained before the experiment. The results of the comparative analysis of the values of the indicators of the relevant tests using the Student’s criterion proved the reliability of the difference between the values of the indicators of all five tests (p<0,001, p<0,01). Conclusions. It is proved that the offered complex of exercises with a half-ball BOSU for the improvement of female volleyball players’ coordination abilities has justified itself as an effective means and is recommended for use in the training activity of female volleyball players.
