Features technical and tactical training of volleyball players of high class of different roles

purpose: to determine the effectiveness of competitive activity of highly skilled players in different roles. Material and Methods: the study used statistical data of major international competitions: the olympic games – 2012, the world cup – 2010, 2014, european championship – 2010–2014 world league – 2010–2014. a total of 130 games was analyzed. methods used: analysis and compilation data of special scientific and methodical literature, analysis of competitive activity of volleyball players of high class, pedagogical observation, methods of mathematical statistics. results: it was found that the most effective of attacking actions during one game performed by highly skilled volleyball players of the world, where players first rate of the attack wins in the fourth part 4,2% balls, the second player tempo attak – 4,5%, «diagonal» – 5,1%. Conclusion: it is proved that the greatest indicator of the effectiveness of competitive activity has a high-class volleyball players that win throughout the game the second player tempo attak 22,1% of balls, «diagonal» – 18,8%, the first rate players – 16,3%.

The results of these studies show that the most effective of the attacking action of the players in first-tempo attacks are highly skilled volleyball players of the world, accounting for 16,3% in comparison with the Ukrainian athletes (team Super League Ukraine -10%, «Burevestnik» -9%).A characteristic feature of competitive activity of highly skilled volleyball players of the world and Ukraine is a gradual increase in the number of won balls by players of the first pace attack, unlike players on the team, «Burevestnik».
Thus, the greatest efficiency attacking actions of the players of this role have highly skilled volleyball players of the world observed in the fourth part (6%), the players of Super League teams in Ukraine -2,6%.The effectiveness of action of the attacking players on the team, «Burevestnik» in the second and the fourth part of 2,7%.This is due to low levels of technical and tactical and psychological preparation for skilled volleyball players,which do not provide the effectively attacking actions of the players of this role.
Table 2 shows the quantitative indicators won balls by highly skilled volleyball players the second pace attack on the results of the official competition 2010 -2014.

The number of won balls in the attack of highly skilled volleyball players of the second tempo on the official Games 2010 The research results indicate that competitive activity has wavy character, the essence of which is to increase the number of attacking action in the fourth part highly skilled volleyball players of the world in relation to other parts to the game.The effectiveness of the attackers actions of highly skilled volleyball players of the world is 8,5% of the total number of actions performed by the attackers; highly skilled volleyball players of Ukraine -in the second and fourth part -3,5%; qualified volleyball team «Burevestnik» observed increase of the number of attacking moves in the fourth part of -4,5%.Performance indicators (Fig. 3) in the second part of the study group of players, has most important: highly skilled volleyball players of the world -5,8%, highly skilled volleyball players of Ukraine -3,9% of skilled players on the team, «Burevestnik» -4,5%.
In the fourth part of the game greatest indicator of the effectiveness of the attacking action belongs to the team of highly skilled volleyball players of the world -3,4%, highly skilled volleyball players of Ukraine -3,1%, qualified volleyball team «Burevestnik» -2,7%, respectively.

The -highly skilled volleyball players of the world; -highly skilled volleyball players of the Ukraine; -qualified volleyball players team «Burevestnik»; 1, 2, 3, 4 -part the game A feature of competitive activity of the «diagonal» players in volleyball there is the use of the largest number of attackers blows, running from the back line of the playing court, with the greatest efficacy at highly skilled volleyball players of the world in the second part -5,1%, highly skilled volleyball players of Ukraine in the third part of the game -4,8%, players command «Burevestnik» -4,5%.
Obtaining objective information allows us to determine the effectiveness of attacking actions of the players of the first and second pace, the values of which are presented in Figure 4. Pedagogical analysis of the effectiveness of technical and tactical actions in the attack, as well as to determine their efficiency in competitive activity of skilled volleyball players allow to state that the most effective attacking actions have «dogrovschiki», who perform the largest amount of technical and tactical actions.The effectiveness of the attacking actions of this role players at highly skilled volleyball players of the world is 22,1%, from highly skilled volleyball players of Ukraine -12,3%, from the players on the team, «Burevestnik» -13,6%.
A feature of the «diagonal» players is the use of the to a greater extent attacking actions carried out from the back of the line of volleyball courts, which brings the most benefit.The contribution of the players of this role in the effectiveness of competitive activity of highly skilled volleyball players of the world -18,8%, in volleyball teams Super League Ukraine -15,9%, the athletes teams «Burevestnik» -14,5%, respectively.Also, we have the tendency to increase the number of attack first-tempo players in the teams of highly skilled volleyball players in the world, where the indicators of efficiency is 16,3% , highly skilled volleyball players Ukrainian win 10% attacks in of the total number of attacking actions, qualified team players «Burevestnik» at 9% cases.
Conclusions.Analysis of these data allows to reveal certain patterns that exist in competitive activity highly skilled volleyball players of different roles: in the team of highly skilled volleyball players of the world, the role «central blocking» the most efficient of attacking − action has in the fourth part of the game is 4,2%, in highly skilled volleyball players of Ukraine -2,7% of skilled volleyball team «Burevestnik» -2,6% of the total the number of balls won; high efficiency attacking action of «doigrovschik» role is performed in the fourth part of the game highly skilled − volleyball players of the world -7,7%, highly skilled volleyball players of Ukraine -3,5%, team players «Burevestnik» -4,5% of the total number of balls won; high efficiency attacking action the players of «diagonal» role has in the second part of the game where in the best − volleyball teams of the world the highest indicator of ball won from the attacking actions of 5,1%, highly skilled volleyball players of Ukraine -4.5%, qualified players on the team, «Burevestnik» value -4,5%; the greatest contribution to the effectiveness of competitive activity have «dogrovschiki»: highly skilled volleyball − players of the world -22,1%, highly skilled volleyball players of Ukraine -12,3%, qualified players on the team, «Burevestnik» -13,6%.
Prospects for further research on this issue will be associated with the development of individual models of technical and tactical training of highly skilled volleyball players based on their playing specializations that will constitute the methodological basis of training and competitive activity of players in volleyball.
