MODEL CHARACTERISTICS OF COMPETITIVE ACTIVITY OF DIFFERENT SKILLED FEMALE VOLLEYBALL PLAYERS

Annotation. Purpose: to determine and compare the model characteristics of competitive activity and an integrated assessment of highly qualified and skilled volleyball players. Material: the study involved 49 highly qualified and 53 qualified volleyball players. Results: identified indicators of competitive activity (intensity factors, mobility, aggressiveness, efficiency and effectiveness ratio of attack-block) and the integral evaluation of volleyball players of various skill levels. Developed a scale evaluation. Built model. Also, a comparison of model characteristics of competitive activity volleyball. Conclusions: the significant differences are fixed model characteristics of competitive activity in athletes of high qualification of different roles. Qualified volleyball, these differences are not so pronounced. This demonstrates the universality of minor league players.


Results of the research
The structure of every model includes model characteristics and indicators [3; 5; 6 et al.]. Competition model is the most significant because optimal performance of team at competitions shall be the result of training process. According to purpose of our research we determined indicators of competition functioning and integral evaluation of highly qualified and qualified volleyball players (see table 1). Comparing data of table 1 we can note that mean results of practically all indicators of qualified sportswomen's competition functioning are lower than the same results of highly qualified sportswomen. Alongside with it, lower variation coefficients of qualified sportswomen witness about universal character of their level. For correct comparison of the received results it was important to evaluate every indicator. That is why the following step was to determine ten-point scale of evaluation of competition functioning indicators on the base of V.M. Kostiukevych's methodic approach [3]. According to "rule of three Sigma" we determined area from + 3S to -3S, which was divided into 9 equal intervals. Value -3S corresponded to 1 point, + 3S -10 points. Value -3S plus value of one interval corresponds to 2 points and etc. Thus, we worked out evaluation scale of competition function for highly qualified and qualified sportswomen -volleyball players.
In compliance with the worked out scale we evaluated indicators of competition functioning of all sportswomen in every group. As a result we obtained models of competition functioning of highly qualified (n=13) and qualified (n=14) center forward (see fig.1 a), highly qualified (n=16) and qualified wing players (n=21) (see fig.1b), highly qualified (n=6) and qualified (n=8) diagonal forwards (see fig. 1 c), highly qualified (n=8) and qualified (n=10) binders (see fig. 1 d), highly qualified (n=6) libero players (see fig.2). a b c d Fig.1. Models of competition functioning of different qualification sportswomen-volleyball players: а -center forwards, b -wing players, c -diagonal forward, d -binder, 1 -coefficient of intensity; 2 -coefficient of mobility; 3 -coefficient of aggressiveness; 4 -coefficient of effectiveness; 5 -coefficient of attack-block effectiveness; 6 -integral evaluation. volleyball players of high qualification qualified volleyball players Analysis of the received results permits to say that the highest coefficient of effectiveness belonged to binders (6.4 points of highly qualified and 7.0 points of qualified volleyball players), because coefficient of intensity reflects quantity of technical-tactic actions, fulfilled by volleyball player in one game; binders participate practically in every combination, creating favorable position for attack. High CI of center forwards (5.9 points of highly qualified and 4.9of qualified volleyball players) is connected with active behavior of these sportswomen on front line: constant attacks, blocks, imitations of attacks and so on. Insignificant difference of coefficient of intensity was between values of diagonal forwards and wing players (4.0 and 4.4 points of highly qualified and 4.6, 4.8 points of qualified sportswomen accordingly). The least CI was registered for libero players (2.9 points) and it was connected with the fact that they participated only in team's defensive actions. Coefficient of mobility characterizes quantity of technical-tactic actions, fulfilled by a player in one game in second and third regimes of coordination complexity. The highest CM was registered in highly qualified libero (7.6 points) that is connected with specificity of coefficient's determination for players of this role [11]. High CM was registered in binders (4.7 points for highly qualified and 6.9 points for qualified players) because it is a quantitative indicator of competition functioning. Concerning forwards of first and second temps, CM does not differ significantly: in highly qualified sportswomen it changes from 3.0 points (diagonal forwards) to 4.0 points (center forwards); in qualified sportswomen -from 4.0 (diagonal forwards) to 4.6 (wing players).
Coefficient of aggressiveness reflects intensity of competition duel directly near net (attacks, block and so on). There are clear distinctions in mean value of CA of highly qualified volleyball players. In particular, the highest CA was registered in center forwards (6.3 points) and the lowest belonged to binders (2.4 points) and it was connected with specificities of game roles. Mean CA value of highly qualified wing players and diagonal forwards was 3.5 points. Concerning qualified sportswomen-volleyball players of different roles CA distinctions were insignificant: for center forwards it was 5.2 points, for wing players -4.7 points, for diagonal forwards -4.4 points, for binders -4.0 points. It was connected with universal character of players' technical level; indeed, owing to unsuccessful defensive actions players have to re-adjust (forwards -realize pass, binders -fulfill attacks).. Coefficient of effectiveness characterizes player's significance in team and is determined as relation of successful technical tactic actions (TTA) to total sum of TTA. It was determined that in general team aspect coefficient of effectiveness of qualified volleyball players is, in average, lower than the same of highly qualified volleyball players; it is connected with higher level of highly qualified volleyball players and, accordingly, with greater number of mistakes and less experience of qualified volleyball players. Alongside with it, we registered that the highest coefficient of effectiveness belongs to both qualified (5.4 points) and highly qualified (6.3 points) binders, whose competition functioning is connected to large extent with partners' actions, who, realizing defensive actions, try to create the best conditions for binders' passes.
Libero -is rather narrow specialization of defense with task to receive ball and pass it to binder, whose perfection is facilitated by players of this role. That is why it is logic that CE of highly qualified libero is 6.2 points.
Forwards, in average, have less coefficient of effectiveness than other players and it is connected with the fact that they more then other are in constant duel with opponents. In particular, there is insignificant difference of forwards' coefficient of effectiveness: diagonal forwards -3.9 points, center forwards-4.7 points, wing players -4.9 points. Concerning highly qualified players, wing players and diagonal forwards have 5.7 points and center forwards -4.5 points. Lower CE of highly qualified forwards of first temp is connected with great quantity of not realized blocks. This also the reason of low coefficient of attack-block effectiveness of center forwards (4.3 points). The lowest of CE (attack-block) among highly qualified players was registered in binders (3,4 points). Wing players and diagonal forwards have insignificant difference in CE (attack-block) -5.7 and 5.3 points accordingly. Qualified wing players have CE (attack-block) 5.8 points and corresponds to highly qualified players' (of the same role) level. Qualified center and diagonal forwards, binders have mean CE (attack-block) in frames from 4.4 points to 4.8 points.
Integral evaluation, which includes both quantitative and qualitative indicators, is an objective criterion of evaluation of volleyball competition functioning. Qualified sportswomen-volleyball players have insignificant difference in integral evaluation. It changes from 4.9 -5.1 points for forwards to 5.8 points for binders. Highly qualified volleyball players have more expressed difference in integral evaluations. In particular the lest results belong to diagonal forwards (4.0 points) and wing players (4.2 points) Integral evaluation at level of 4.6 and 5.1 points belonged to libero and binders accordingly. The highest integral evaluation had center forwards; it was 6.4 points. вона становить 6,4 бали.

Conclusions:
1. Analysis of scientific literature showed demand in determination of model characteristics of competition functioning of sportswomen-volleyball players of different qualification, which would permit to increase effectiveness of training and competition processes' management and serve as bench marks for future researches.
2. We have determined that mean indicators of competition functioning of qualified sportswomen-volleyball players statistically differ (p<0.05) from results of more experienced, highly qualified sportswomen.
3. We have registered substantial distinctions of model characteristics of competition functioning of highly qualified sportswomen (of different game roles), while, at the same time, in qualified volleyball players these distinctions are not so expressed that witness about universal character of technical level of less experienced volleyball players.
The prospects of further researches imply studying of interconnections between indicators of physical, functional and technical-tactic fitness as well as competition functioning of sportswomen-volleyball players.
