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.
