PEDAGOGIC CONTROL INDICATORS OF 14-15 YEARS AGE GIRLS ’ MOTOR FITNESS

Purpose: to determine informative indicators for in-group and intra-group control of 14-15 years age girls’ motor fitness. Material: in the research 99 girls participted: 14 years old (n=38), 15 years old (n=61). Results: for control of 15 years age girls’ motor fitness the most informative are indicators of speed power, dynamic power endurance and physical condition. It was found that 14 years age girls have better power fitness than 15 years girls. It points at the fact that in 15 years’ age the reasons of lagging behind 14 years girls are increase of body mass and reduction of motor activity. Conclusions: the received data show that factorial analysis as well as discriminant one is methodological base for determination of tests’ in-group and intra-group informational potential. The most informative tests for determination of age dynamic are static and dynamic power endurance of abdomen muscles and connected with them result of long jumps from the spot.


Results of the research
In table 1 we gave results of motor fitness testing of 14-15 years' age girls.Analysis of testing results shows that 14 years girls demonstrate statistically confidently better results in tests №3 "Keeping angle on parallel bars, sec.",№6 "Pressing ups in lying position, quantity of times" (р<0.05).15 years girls have statistically confident difference from 14 years girls by body mass and are statistically confidently better in tests №4 "Right hand strenth, kg", №5 "Left hand strength, kg", №8 "Long jump from the spot, cm", №10 "Forward torso bending from sitting position, cm", №11 "Shuttle run 4х9 m, sec.",№12 "Taking sitting position from lying position during 60 sec., quantity of times" (р<0.05).
Difference in results of tests №7 "Chin ups, quantity of times", №9 "Legs' raising up to straight angle from hanging on Swedish wall position, quantity of times" between 14 and 15 years age girls statistically was not confident (р>0.05).For determination of the tests' in-group informational potential for 14 years girls we conducted factorial analysis by results of 13 tests (see table 2).In the process of analysis we marked out four factors, which explain 66.992% of indicators' total dispersion.
Factor 1 is the most informative (24.094%).It correlates with static and dynamic strength of abdomen muscles and speed power fitness.The factor was named "power fitness".
Factor 2 (information potential 15.770%) correlates to the largest extent with hand static strength.It was named "static power fitness".Factor 3 (information potential 14.566%) correlates to the largest extent with test № 13"From lying on abdomen position torso raising upward during 60 sec., quantity of times".The factor was named "dynamic endurance of back muscles".
Factor 4 (information potential 12.563%) correlates to the largest extent with relative strength indicator.It was named "relative strength".
Analysis of populations shows that for motor fitness control the most informative are tests №4 "Right hand strength, kg", №5 "Left hand strength, kg", №8 "Long jump from the spot, cm", №13 "From lying on abdomen position torso raising upward during 60 sec., quantity of times".For determination of the tests' in-group informational potential for 15 years girls we conducted factorial analysis by results of 13 tests (see table 3).In the process of analysis we marked out five factors, which explain 70.630% of indicators' total dispersion.
Factor 1 is the most informative (17.237%).It correlates with hand static strength and was named "static strength".
Factor 2 (information potential 15.614%) correlates to the largest extent with relative strength.It was named "power fitness".
Factor 3 (information potential 14.257%) correlates to the largest extent with physical condition indicators.The factor was named "Physical condition".
Factor 4 (information potential 10.288%) correlates to the largest extent with speed power (test No.8 "Long jump from the spot, cm" and dynamic endurance of abdomen muscles (test No.12 "Taking sitting position from lying position during 60 sec.".It was named "Power fitness".
Factor 5 (information potential 10.288%) correlates to the largest extent with flexibility indicators (test No.10 "Forward torso bending from sitting position, cm" (test No.8 "Long jump from the spot, cm" and dynamic endurance of abdomen muscles (test No.12 "Forward torso bending from sitting position, cm".It was named "Flexibility". Analysis of populations shows that for motor fitness control the most informative are indicators of speedpower (test №8 "Long jump from the spot, cm", dynamic power endurance (test No.12 "Taking sitting position from lying position during 60 sec." and physical condition.For determination of tests' intra-group informational potential we conducted discriminant anlysis of 14-15 years age girls' motor fitness.The anlysis showed that tests №10 "Forward torso bending from sitting position, cm" and № 3 "Keeping of angle on parallel bars, sec."make the biggest contribution in change of function (see table 4, standardized coefficients).The highest correlations with function have tests №12 "Taking sitting position from lying position during 60 sec., quantity of times", №8 "Long jump from the spot, cm", №3 "Keeping of angle on parallel bars, sec."(see table 4, structural coefficients).So, the most informative coefficients for age dynamic determination are static and dynamic power endurance of abdomen muscles and connected with it result of long jumps from the spot.

Discussion
For practical application of discriminant analysis results canonic discriminant function coefficients for classification shall be used (see table 4).
Analysis of the received results shows that 14 years age girls have better power fitness (test № 3 " Keeping of angle on parallel bars, sec.",test №6 " Pressing ups in lying position, quantity of times") than 15 years age girls.It points that in 15 years age the reasons of lagging behind 14 years girls are increase of body mass and reduction of motor activity.It supplements the data of other authors [4,15,16] illustrating that the reason of adolescents' low motor fitness is significant reduction of motor functioning.All these take place together with loss of interest to school physical culture lessons and negative attitude to physical culture in general The received results expand information about special aspects of motor abilities' development in children and adolescents and permit to obtain new information with the help of modeling method [5, 23, and 32].
The received data supplement also the data of other authors [27,29,33] about demand in structural and functional analysis of children's and adolescents' motor fitness as well as they prove the opinion that discriminant model can be used for pedagogic control of 14-15 years age schoolchildren's fitness level.The received functions can further be used in new observations with known predictor variables and unknown belonging to group.
The propesct of further researches are determination of discriminant function effectiveness in managing children's and adolescents' physical education.

Conclusions
For control over 14 years girls' motor fitness the most informative are tests №4 "Right hand strength, kg", №5 "Left hand strength, kg", №8 "Long jump from the spot, cm", №13 " From lying on abdomen position torso raising upward during 60 sec, quantity of times".
For control over 15 years girls' motor fitness the most informative are speed power indicators (test №8 " Long jump from the spot, cm"), dynamic power endurance (test №12 " Taking sitting position from lying position during 60 sec., quantity of times") and indicators of physical condition.
The obtained data witness that factorial and discriminant analysis are mehodological base for determination of tests' in-group and intra-group informationaql potential.For determination of age dynamic the most informative tests are static and dynamic endurance of abdomen muscles and connected with them result of long jump from the spot.The electronic version of this article is the complete one and can be found online at: http://www.sportpedagogy.org.ua/html/arhive-e.htmlThis is an Open Access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited (http://creativecommons.org/licenses/by/4.0/deed.en).
