Monitoring the physical condition of 13-year-old schoolchildren during the process of physical education

Abstract

The article presents the results of monitoring of the physical condition of schoolchildren. In this study, 281 subjects who consisted of 13-year-old boys (n=145) and girls (n=136) were enrolled. For health reasons they are referred to the main and preparatory medical group. According to the stated purpose, in the process of physical education, we studied 30 indicators characterizing physical development, the functional state of the cardiovascular and respiratory system, the level of physical health, the level of physical performance, the level of basic motor qualities development and the level of morbidity by the main classes of diseases. The results obtained during the monitoring of the physical condition of schoolchildren testified that the average statistical parameters of body weight and chest circumference in girls are significantly lower (p<0.05) than the anthropometric standards. In boys, the average statistical values of body length, body weight and chest circumference are also significantly lower (p<0.001) than the anthropometric standards. Analysis of the functional state of the cardiovascular system in 13-year-old schoolchildren displayed that individual results of the heart rate at rest corresponded to the age norms in 30.9 % (n=42) of girls, while there were only 19.3 % (n=28) of boys whose results corresponded to the age standards. The statistically average result of the level of physical health in girls and boys corresponds to the average level. According to the results of the Ruffier index, the largest percentage of the girls under study 51.5 % (n=70) had an average reaction level for dynamic load, the overwhelming majority of boys - 66.2 % (n = 96) - had a satisfactory level. Disorders of the musculoskeletal system predominated among the diseases, and in the most of the girls and boys are related.
