FACTOR ANALYSIS OF INDICATORS OF PHYSICAL DEVELOPMENT, PHYSICAL FITNESS AND FUNCTIONAL EQUILIBRIUM STATUS AS PREREQUISITES FOR THE DEVELOPMENT OF THE CONCEPT OF APPLICATION OF PHYSICAL AND HEALTH TECHNOLOGY FOR SCHOOLCHILDREN WITH VISUAL IMPAIRMENT ADAPTI

Abstract

The article discusses the issue of reducing the motor activity of schoolchildren with visual impairment, which determines the presence of low indicators of physical development, physical fitness and functional balance, as a prerequisite for the development of the concept of the use of physical culture and health technology for schoolchildren with visual impairment in the process of adaptive physical education, which is confirmed by factor analysis. The relevance of the problem, goal and task of the research is formulated. The purpose of the article was to reveal the prerequisites for the development of the concept of the use of physical culture and health technology for schoolchildren with visual impairment in the process of adaptive physical education. The tasks of the research were: to carry out a factor analysis of indicators of physical development, physical fitness and functional state of balance of schoolchildren with visual impairment. Factor analysis was carried out based on the data of the study on the general sample of schoolchildren aged 10-13 with visual impairment (47 people). Based on the results of the factor analysis in the groups, structures consisting of 3 factors were obtained. The value of KMO indicated the acceptable adequacy of samples for factor analysis (KMO>0.5), and Bartlett's test (p<0.01) in all cases indicated the feasibility of this procedure due to the correlation of factors. The total informativeness of all factors was in different cases from 0.743 to 0.837, that is, the selected factors explained approximately 74-84 percent of the total variance of the features, which is considered an acceptable result. The factor structure as a whole explained 80.7% of all the variability of the signs. The first factor «Coordination and balance development» (36.56%) was bipolar and reflected the ability of the subjects to develop physical coordination. The second factor «Body parameters» (25.37%) indicated a negative relationship between exceeding the age norms in the development of the body of schoolchildren and their physical fitness. The third factor «Strength and dexterity» (18.77%) consisted of the poles of positive and capacity loads, which reflected the importance of the development of strength, dexterity and aerobic endurance of schoolchildren. It was revealed in the scientific study that the most significant aspects of the physical development of schoolchildren with impaired vision are: improvement of coordination and balance, control of physical parameters of the body, increase of motor activity and improvement of physical The presented data can be considered as one of the prerequisites for the development and implementation of the concept of the use of physical culture and health technology for schoolchildren with visual impairment in the process of adaptive physical education.
