Informative Indicators of 14-15 Years’ Age Boys’ Motor Fitness

Abstract

The purpose of the research is to determine informative indicators for in-group and intra-group control of 14 and 15 years’ age boys’ motor fitness. 
 Material & methods: in the research 112 schoolchildren participated: 14 years’ age (n=44), 15 year’ age (n=68). The materials of the research were processed in program of statistical analysis IBM SPSS 20. Factorial analysis as well as discriminant were fulfilled. 
 Results of the research: it was found that for control of motor fitness the most informative indicators were indicators of static power endurance and physical condition. It was also found that results of test “keeping angle on parallel bars” made the highest contribution in function’s change and the closest correlation with the function. 
 Conclusions: 14 years’ boys have better indicators of static and relative strength than 15 years’ age boys. It points at the fact that in 15 years’ age sharp changes of body mass, weight as well as reduction of motor functioning are the reasons of lagging behind. The received data witness that factorial and discriminant analysis can be methodological base for determination of tests’ in-group and intra-group informational potential. For comprehensive control of motor fitness test “Keeping of angle on parallel bars” can be recommended.

Motor Abilities: Identification of Development Level in Boys Aged 12-14

“…The above-mentioned results show that discriminant analysis allows to identify the state of motor abilities development in boys aged 12-14 by the results of testing and supplement data on the use of discriminant function in classifying schoolchildren by motor activity (Gert-Jan de Bruijn, & Benjamin Gardner, 2011; Lulzim, 2013). As in the papers by Broadhead and Church (1982), Ivashchenko, Kapkan, Khudolii, and Yermakova (2017), Ivashchenko, Khudolii, Iermakov, Veremeenko, and Lopatiev (2018), we observed a high discriminative and predictive ability of these functions in evaluating motor preparedness of boys aged 12-14. The study confirmed that multidimensional methods of mathematical statistics such as factor and discriminant analyses (Ivashchenko, 2014;Lopatiev, Ivashchenko, Khudolii, Pjanylo, Chernenko, & Yermakova, 2017;Ivashchenko, Khudolii, Iermakov, Chernenko, & Honcharenko, 2018) are effective for studying the structure of motor preparedness of boys aged 12-14.…”

The study added that he use of discriminant function in the analysis of standardized and structure coefficients allows to determine the structure of strength abilities development and their interrelation with endurance in boys aged 12-14 (Ivashchenko, 2017;Ivashchenko, Kapkan, Khudolii, Yermakova, 2017;Ivashchenko, Khudolii, Iermakov, & Harkusha, 2017).…”

“…Factor analysis, which determines informative indicators, is used to evaluate the current state. To evaluate the state dynamics in the series of lessons and in an age range, discriminant analysis is used, it allows to determine informative indicators for comprehensive control and to determine what class of preparedness the pupil belongs to based on discriminant functions (Ivashchenko, 2017;Ivashchenko, Kapkan, Khudolii, Yermakova, 2017). In available literature, however, there are not enough data on the peculiarities of evaluating motor abilities development in middle school students.…”

Power abilities: the structure of development in girls of 12-14 years old

“…The factor with the greatest correlation is the following: It is confirmed that multidimensional methods of mathematical statistics are effective for the study of the strength training structure of girls aged 12-14 years: factor and discriminant analysis [7,20]. It is added that the use of factor analysis allows to determine the structure of the development of power abilities and their interrelation with endurance in girls aged 12-14 years [21,22].…”

“…Multidimensional methods of mathematical statistics such as factor and discriminant analysis [7,20] are effective for studying the structure of motor readiness of schoolchildren. Using factor analysis allowed to establish the structure of motor readiness of schoolchildren [21,22]. However, in available literature there is not enough data on the peculiarities of the structure of power abilities development among middle class students.…”
