ASSESSMENT OF FUNCTIONAL, COORDINATION AND POWER FITNESS OF 7-8 FORM BOYS

Purpose: determination of informative indicators of 7-8 form boys’ motor and functional fitness. Material: in the research 24 pupils of 7th form and 35 pupils of 8th form participated. For assessment of functional and motor fitness test of Shtange, Genchi, Serkin and motor tests were conducted. Results: Analysis witnesses that be results of testing between boys of 7th and 8th dorm there are statistically confident differences by most of indicators (p<0.05:0.001). By functioning of respiratory and blood circulation systems 7-8 form boy pupils were assessed as healthy-not trained. Conclusions: structural coefficients of canonic discriminant function witness that the function is connected to the largest extent with variables. So, substantial difference between 7th for pupils and 8th form pupils was observed in condition of motor abilities: speed-power, coordination of movements and strength itself.

Introduction 1  Health of nation is an integral indicator of social-economic and spiritual condition of society.As it is known human health is formed in children's and adolescent's age.This process is influenced by many factors: genetic factors, way of life, social economical and ecological conditions.As per scientific data schoolchildren's health has significantly worsened recent years [1,2,5,6,26].In target complex program "Physical education -health of nation" it is noted that situation with health, especially health of children and adolescents is extremely unsatisfactory in Ukraine.Nearly 90% of pupils have health disorders; above 50% have insufficient physical fitness.
One of conditions of improvement of schoolchildren's motor fitness is organization of pedagogic control at physical culture lessons [3,4,11,13], and in conditions of sport training [9,10,[13][14][15][16].Procedure of pedagogic control is classification of current state of motor and functional fitness, on which taking decisions in controlling of children's and adolescents' physical education depends.
So, classification of motor fitness is of practical importance for taking decisions in controlling of children's and adolescents' physical education.Classification is also important for working out of effective programs of children's and adolescents' physical training.
In researches of O.M. Khudolii and S.S. Iermakov (2011), O.M. Khudolii and O.V. Ivashchenko (2013) there were worked out conceptual approaches to simulation of motor abilities' training in children and adolescents.Also models of motor skills' training, which can be used for current and summarizing control of children and adolescents' fitness, are regarded.By the data of different [4,12,[20][21][22] current control over children's and adolescents' motor fitness can be realized on the base of discriminant analysis.
However, in available scientific literature there is paid insufficient attention to application of simulation method for classification of motor and functional fitness of children and adolescents.
That is why, solution of problem of assessment and detection of secondary form pupils' functional and motor fitness is rather urgent.
Purpose, tasks of the work, material and methods The purpose of the research: is determination of informative indicators of 7-8 form boy-pupils' motor and functional fitness.
The methods of the research: the following methods were used -analysis of scientific-methodic literature, pedagogic testing and methods of mathematical statistic.
For assessment of 7-8 form pupils' functional and motor fitness we registered results of tests of Shtange, Genchi, Serkin and motor tests.

Results of the research
Results of the research are given in tables 1-5.Analysis witnesses, that by testing results there are statistically confident differences between boys of seventh and eighth forms by most of indicators (p<0.05:0.001).By functional state of respiratory and blood circulation system 7-8 form pupils are assessed as healthy but not trained.
Statistically confident differences are also observed between 7-8 form pupils in tests, which characterize coordination fitness and strength itself (р<0.001).Boys from 7 th form have better fitness by results of tests 1, 5 and 6 (p<0.001).Boys from 8 th form have better indicators of speed power, static power, coordination and functional state of respiratory and blood circulation systems.
In tables 2-5 we present results of discriminant analysis, which permit to classify 7-8 form pupils by their functional state and motor fitness.
In table 2 we can see normalized coefficients of canonic discriminant function, which permit to determine correlation of variables' contribution in result of function.With the greatest contribution variables 10, 6, 11 and 8 enter canonic function: the higher values of these variables are, the bigger is value of the function.The above said witnesses about possibility of classification of seventh and eighth forms boys' age distinctions on the base of testing of functional, coordination and power fitness.
In table 5 we give coordinates of centroids for first (7 th form) and second (8 th form) groups.They permit to interpret canonic function in respect to its role in classification.At negative pole there is centroid for 8 th form; at positive polefor 7 th form.It witnesses about substantial difference in fitness of seventh and eighth forms' pupils.In table 2 we can see normalized coefficients of canonic discriminant function, which permit to determine correlation of variables' contribution in result of function.With the greatest contribution variables 10, 6, 11 and 8 enter canonic function: the higher values of these variables are, the bigger is value of the function.The above said witnesses about possibility of classification of seventh and eighth forms boys' age distinctions on the base of testing of functional, coordination and power fitness.
In table 5 we give coordinates of centroids for first (7 th form) and second (8 th form) groups.They permit to interpret canonic function in respect to its role in classification.At negative pole there is centroid for 8 th form; at positive polefor 7 th form.It witnesses about substantial difference in fitness of seventh and eighth forms' pupils.
In table 3 we present structural coefficients of canonic discriminant function, which are coefficients of variables' correlation with function.For example, function is most significantly connected with variables № 8, 6, 4 and 5: so substantial difference between boys of seventh and eighth forms is observed in condition of motor skills: speed-power, coordination and strength itself.
In table 4 one can see results of groups' classification.100% of final grouped observations are classified correctly.Thus, canonic discriminant function can be used for classification of age peculiarities of seventh and eighth forms' boys.

Discussion
In the researches in the sphere of physical education and sports discriminant function is used for classification of pupils by their motivation for sport training [24], by motor activity [19], for classification of groups into sportsmen and not sportsmen [23], for determination of dynamic of 9-12 years' age children's physical condition under influence of fitness-programs [17].
Geoffrey D. Broadhead and Gabie E. Church (1982) points at possible application of disciminant analysis for classification of 5-12 years' age children's motor functioning, depending on its scope.Equations of discriminant functions permit for 93% of grouped data to be classified correctly.Titarenko А.А. ( 2010 The purpose of discriminant analysis is studying of discriminant function's coefficients in order to maximally accurately classify pupils into groups with the help of their values.It permits to solve two groups of problems: • to answer the question how confidently one can separate one form from other by set of offered variables; which of these variables render the most significant influence on distinguishing of forms; • to classify objects on the base of discriminant function.I.e.answer the question: to which class (form) object belongs on the base of values of discriminant variables.
In experiment we detected that by set of the offered variables it is possible to statistically confidently (р < 0.001) separate seventh form boys from eighth form pupils.
So, for finalizing pedagogic control of seventh boys' motor and functional fitness we can use first discriminant function with accent on the most informative variables.If results of seventh form's boys are classified as similar to results of eighth form's boys, we can speak about effectiveness of physical education.

Conclusions:
1. Analysis witnesses, that by most of indicators there are statistically confident differences between 7 th and 8 th forms boys (p<0.05:0.001).By functional state of respiratory and blood circulation system 7-8 form pupils are assessed as healthy but not trained.
2. Statistically confident differences are also observed between 7 th and 8 th forms boys in tests, which characterize coordination and power fitness (р<0.001).7 th form's boys are better by results of tests 1, 5 and 6 (p<0.001).8 th form's boys have better indicators of speed-power and static power, coordination and functional state of respiratory and blood circulation systems.
3. Normalized coefficients of canonic discriminant function permit to determine correlation of variables' contribution in function's result.Variables 10, 6, 11 and 8 enter in function with largest contribution: the higher values of these variable are, the bigger if value of the function.The above said witnesses about possibility to classify of age distinctions of seventh and eighth forms' boys on the base of testing of their functional, coordination and power fitness.
4. Structural coefficients of canonic discriminant function witness, that the function is most substantially connected with variables № 8, 6, 4 and 5: so, significant difference between boys of seventh and eighth forms is observed in condition of motor skills, speed-power, coordination and strength itself.
