Level of physical exercises’ mastering in structure of 11-13 yrs age boys’ motor fitness

Purpose: to find the place of physical exercises’ mastering level in structure of 11-13 yrs age boys’ motor fitness.Material: in the research 11 yrs age boys (n=58), 12 (n=76) and 13 years age (n=93) participated. Testing program included well-known tests: “Forward roll”, “Backward roll”, “Vault”, ”Climbing rope (three attempts)”, “Bridge”, “Stance on shoulder blades”.Results: By indicators of physical condition 11-13 yrs age boys statistically confidently differ one from another (р<0,001). Level of mastering of gymnastic exercises “Backward roll”, “Vault”, ”Climbing rope (three attempts)”, “Bridge”, “Stance on shoulder blades” with age statistically confidently increases (р<0,001).Conclusions: In factorial structure of motor fitness, level of physical exercises’ mastering has weight 17,5% (11 yrs age), 36,6% (12 years), 28,5% (13 years). Analysis of communities showed that in 11-13 yrs age boys training of motor abilities is effective (if they become a component of mastered motor skills).

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

Цель исследования. определить структуру развития силовых способностей у девочек 12-14 лет. Материалы и методы. В исследовании приняли участие девочки в возрасте 12 лет (n = 20); 13 лет (n = 27), 14 лет (n = 30). Проведен факторный анализ. Результаты. Определено, что наиболее информативными у девочек 12-14 лет являются тесты: характеризующих развитие динамической и статической силы мышц ног и рук (девочки 12 лет); характеризующих развитие статической, скоростной силы мышц ног, статической и динамической силы мышц живота и рук (девочки 13 лет); характеризующих развитие статической и динамической силы мышц ног, динамической силы мышц рук (девочки 14 лет). Выводы. Анализ позволил определить информативные показатели для контроля развития силовых способностей у девочек 12-14 лет. У девочек наибольший вес в силовой подготовленности имеет относительная и статическая сила мышц ног. У девочек 12-13 лет на втором месте развитие силы мышц плечевого пояса. У девочек 14 лет на втором месте развитие динамической и статической силы мышц живота и динамической силы мышц плечевого пояса. У девочек 12 лет на третьем месте развитие координации движений, статической силы плечевого пояса и динамической силы мышц спины. У девочек 13 лет на третьем месте развитие развитие силы мышц живота. У девочек 14 лет на третьем месте развитие скоростной силы и координации движений.

Simulation of the regularities of physical exercises learning process of boys aged 8 years old

Purpose: to determine the peculiarities of the formation of motor skills in boys aged 8 years. Materials and methods: In study participated boys of eight years old (n=48). The study used factor experiment plans. The purpose of this experiment was to optimize the modes of education and to determine the peculiarities of the formation of motor skills in boys. Results: Discriminant analysis allowed: to determine the modes of exercise in the formation of motor skills; to answer the question as to how significantly different modes of work on the effectiveness of the formation of motor skills. Established: which of the variables most significantly affect the differentiation of classes; to which class the object belongs based on the values discriminant variables. The influence of the number of approaches, the number of repetitions in the approach and the interval of rest on the level of training for movements is revealed. Conclusions: To choose the most rational mode of exercising in the process of forming motor skills can be used the first discriminating function with an emphasis on the most informative variables.

The peculiarities of motor fitness’ classification model of 6-10 years old girls

The purpose of the research is determination of motor fitness’ classification model of 6-10 years old girls. Material and methods: in the research 6 years old girls (n=36), 7 years old girls (n=48), 8 years old girls (n=57), 9 years old girls (n=38), 10 years old girls (n=46) participated. Testing program includes commonly known tests. Results: With age there happened some changes of coordination and power fitness, endurance, quickness, flexibility indicators. Suggested set of tests could be used for final control of girls’ motor fitness. Conclusions: In the process of analysis was calculated canonic coefficients of discriminant function (not standardized). These coefficients are multipliers of the set values of variables, which are components of discriminants functions. On the basis of them it is possible to classify girls by the level of motor fitness according to their age.
