Abstract
Objective: To determine the presence and informative significance of the relationship between physical development, functional status and physical fitness of students 7-10 years. Material and methods: the research was conducted in rural schools of villages Kovalyn and Divychky of Pereyaslav-Khmelnitsky district of the Kiev region. 137 children participated in the research, among them 33 pupils 1 form, 29 of 2 form, 37 pupils 3 form, and 38 pupils of 4 form. It used a range of methods, theoretical analysis and synthesis of the literature data; pedagogical methods; testing; anthropometric; physiological (Rufie); methods of mathematical statistics. Results: The factor analysis of the main components of motor activity of children of 7-10 years shows that there is a correlation between physical abilities and morphofunctional state, which is manifested in the presence of the overwhelming majority of integrated factors. Some gender and age differences were identified. However, as far as the content of most factors is concerned, identical trends are observed. So, it has been found that anthropometric and functional indicators in all sex-age groups are located in the most influential factors - I and II combined with indicators of motor tests. Conclusions: the results of factor analysis allowed us to identify the physical qualities that are more related to the morpho-functional state of the body. According to the rating, both boys and girls are distributed as follows: І - speed, ІІ - coordination abilities, ІІІ - speed-power, ІV - endurance, V - strength, VI - flexibility. It gives an opportunity to determine the correlation of different exercises in different directions in physical education and extracurricular activities. Key words: factor analysis, motor system, physical education, younger schoolchildren.
