Визначено проблеми функціонування системи фізичної культури в умовах загально освітньої школи. Досліджені вікові особливості стану розвитку сили та швидкісно-силових здібностей хлопчиків 10-12 років. Розраховані таблиці, які дозволяють не тільки визначати оцінку ефективності педагогічних дій вчителя, а й забезпечують можливість диференціації відповідного контингенту.
It is revealed that the level of health and physical fitness of school-age children are systematically reduced, increases the amount of disease and of particular concern among physicians and specialists in physical education as a cause of development of force and different forms of its manifestation. One of the mechanisms for increase of efficiency of pedagogical activity differentiation is contingent on the level of its readiness. Implementation of this approach enables selective impact on the student through selecting and varying the amount and intensity of physical activity. Study on development of force and quick force boys 10-12 years showed the presence of dynamic processes with positive ones, regardless of the indicator, have a high level of statistical significance. The largest increase are the results of the bending and unbending of hands in push-up position. However, if 10 to 11 corresponding to the amount of change is 31.6%, from 11 to 12 years – to 13.6%. Moreover, the decreasing trend of dynamic processes observed in age group for all indicators, while the lowest dynamics is defined at the jump in length and is 11 to 12 years of 7.2%. Developed assessment of the development of force and quick force students 10-12 years allows to differentiate the specified contingent on the level of preparedness, which in practice reduces the possibility of overexertion of body functions and improves the efficiency of the pedagogical action. Presents guidelines include implementation of physical training in the use of different methods of organization of classes of physical culture.
