Assessment of physical factors of the educational environment in schools of the Chelyabinsk region and their influence on students’ adaptation

Abstract

Introduction. The health of children and adolescents is a criterion of their body’s relationship with the environment and is formed under the influence of a complex set of social, biological and environmental factors. Educational organizations are the only system of public education that covers the entire child and adolescent population of the country for a long period of time. Physical factors of the intra-school environment affect the physiological processes of the body of schoolchildren and ensure adaptation to physical exertion. The purpose of the study: to study and evaluate the physical factors of the educational environment in schools of the Chelyabinsk region in the dynamics of five years and the adaptive potential of students. Materials and methods. Statistical, mathematical and instrumental research methods are used in the work. The conditions of physical education classes in 10 schools in the cities of the Chelyabinsk region from 2018–2022 were studied and an assessment of physical performance was carried out in 102 students of grades 8–9. It was found that the largest share was accounted for by objects classified as medium risk and moderate risk in 2020–82.8 %. Results. The proportion of educational institutions that do not meet sanitary and hygienic standards in terms of artificial illumination and electromagnetic studies remained high and amounted to 14.2 % and 8.9%, respectively, excess air temperature was detected in 20 % of the studied schools. In 60 % of the schools studied, outdoor sports grounds have not been repaired since they were put into operation. Conclusion. 26.7 % of respondents showed satisfactory adaptation to physical exertion, 73.3 % (2.8 times more) of respondents noted the strain of adaptation mechanisms. The number of students with overweight and revealed stress of adaptation mechanisms was 66.7 %, and with a lack of body weight, this figure was 2.1 times less and amounted to 28.5 %. A third (33.3 %) of overweight respondents showed satisfactory adaptation, while underweight students showed 2.2 times higher (71.5 %).
