STRUCTURAL MODEL OF IN-GROUP DYNAMIC OF 6-10 YEARS OLD BOYS’ MOTOR FITNESS

Purpose: to determine structural model of in-group dynamic of 6-10 years old boys’ motor fitness. Material: in the research 6 years old boys (n=48), 7 years old (n=45), 8 years old (n=60), 9 years’ age (n=47) and10 years’ age (n=40) participated. We carried out analysis of factorial model of schoolchildren’s motor fitness. Results: we received information for taking decisions in monitoring of physical education. This information is also necessary for working out of effective programs of children’s and adolescents’ physical training. We determined model of motor fitness and specified informative tests for pedagogic control in every age group. In factorial model of boys’ motor fitness the following factor is the most significant: for 6 years – complex development of motor skills; for 7 years also complex development of motor skills; for 8 years – strength and coordination; for 9 years – complex development of motor skills; for 10 years – complex development of motor skills. Conclusions: In factorial model of 6-10 years old boys’ motor fitness the most significant are backbone and shoulder joints’ mobility, complex manifestation of motor skills, motor coordination. The most informative tests for assessment of different age boys’ motor fitness have been determined.

One of conditions of schoolchildren's motor fitness improvement is organization of pedagogic control at physical culture lessons [4,5,6,17,19,33,34,35,36,37], in conditions of sport training 3,18,16,17,27].Effectiveness of pedagogic control depends on the presence of object of control and informative indicators characterizing change of its state.In recent publications it has been determined that modeling is an effective method for receiving of new information concerning current and finalizing control on the base of testing of children's and adolescents' motor fitness [13,33,34,35,36,37].One of methods of statistical modeling is factorial and discriminant analysis.Effectiveness of their application is witnessed by the data of scientific literature [29,30,31,32,33,34,35,36,40].The mentioned works note that it is necessary to search methodological approaches to solution of motor fitness problems and pedagogic control of children and adolescents.
So, determination of motor fitness factorial model is of practical importance for taking decisions in monitoring of physical education as well as for working out of effective programs for children's and adolescents' physical training.

Purpose, tasks of the work, material and methods
The purpose of the research: is to determine structural model of group dynamic of 6-10 years old boys' motor fitness.
The methods of the research: for solution of our tasks we used such methods as analysis of scientific literature, pedagogic testing and methods of mathematical statistic.Factorial analysis was used as method of modeling.
In planning of the research we used conceptual approaches to working out scientific researches' programs in physical education and sports [1,8,12,14].
Testing program included commonly known tests [10,11,21,22] for assessment of 6-10 years old boys' motor fitness.We registered results of motor tests.The results are presented in table 1.

Results of the research
For determination of structural model of in-group dynamic of boys' motor fitness we carried out factorial analysis by 15 indicators.Results of analysis are given in table 1.First factor (informative potential 20.678%) has the highest correlation with results of tests № 10 (-0.878), № (0.764), № 11 (0.783).The factor characterizes level of endurance and strength itself.
Forth factor (informative potential 14.823%) has the highest correlation with results of test № 3 (-0.907).The factor was named coordination of movements of different body parts.
Fifth factor (informative potential 14.823%) has the highest correlation with results of test № 4 (0.924) and it characterizes vestibular stability of 6 years old boys.
In group of 7 years old boys, analysis marked out also five factors, which explain 64.015% of dispersion's variations.
Fifth factor (informative potential 7.511%) has the highest correlation with results of test № 7 (0.900) and it characterizes dexterity of 7 years old boys.The factor was named dexterity.
In group of 8 years old boys' analysis marked out also five factors, which explain 62,861% of dispersion's variations.
Fifth factor (informative potential 8.3%) has the highest correlation with results of test № 4 (0.775) and characterizes vestibular stability of 8 years old boys.The factor was motor coordination.
In group of 9 years old boys, analysis marked out also five factors, which explain 64.286% of dispersion's variations.
Fifth factor (informative potential 9.174%) has the highest correlation with results of test № 13 (0.865) and characterizes flexibility of 9 years old boys.The factor was flexibility.
In group of 10 years old boys, analysis marked out also five factors, which explain 71.586% of dispersion's variations.
Forth factor (informative potential 12.519%) has the highest correlation with results of tests № 3 (0.898), № 13 (0.643).The factor was named motor coordination of different body parts.
Fifth factor (informative potential 11.865%) has the highest correlation with results of test № 14 (0.938) and characterizes flexibility of 10 years old boys.The factor was flexibility.
