标题：Dynamics of change of high-speed and strengt preparedness of volleyball players under the influence of a set of exercises according to Тabata protocol
摘要：to determine changes in indicators of speed-strength abilities of volleyball players under the influence of a set of exercises according to the Tabata protocol. Material & Method: 10 volleyball players of the male student team “KhSAPC”, aged 17-21, took part in the pedagogical experiment, they have the first category in volleyball. The experiment lasted 2 months and consisted in using the Tabata protocol in the educational and training process of volleyball players. In the dynamics of the experiment, the speed-strength abilities of a selected group of volleyball players were tested. The assessment of the statistical reliability of the results of a comparative analysis of the indicators studied in this work was carried out using a nonparametric sign test. Results: at the beginning of the pedagogical experiment, volleyball players had the following test results: push-ups for 20 s 17,30±0,45 times; standing long jump with push of two legs 229,20±2,98 cm; lifting the torso from the prone position in 30 s 30,40±1,37 times; throwing a stuffed ball weighing 1 kg from behind the head with two hands in a jump of 11,20 ± 0,93 m; jump up from a place (according to V. M. Abalakov) 49,60±2,51 cm. After the pedagogical experiment, the values of indicators of the speed-strength abilities of volleyball players for each of the five tests turned out to be significantly higher compared to the results of the corresponding tests obtained before the start of the experiment. Conclusions: the proposed sets of exercises according to the Tabata protocol turned out to be effective, as they made it possible to significantly improve (p˃0.01) the speed-strength abilities of volleyball players in all tests. The results obtained allow us to recommend the use of exercise complexes according to the Tabata protocol for the training activity of volleyball players.
