A favorable period for the development of endurance in schoolchildren aged 7-18 years

Abstract

The aim of the study is to study the sensitive periods of endurance formation in school-age children. Methods: The pedagogical experiment was organized at secondary school 60, Kirov city in Russia in the period from September 2022 to May 2023. The study involved 578 boys and 637 girls who were admitted by doctors to physical education classes at school. All children took the Cooper control test for 6 minutes at the beginning and at the end of the experiment. Physical education classes were held according to the standard program under the work of physical education teachers. The study used methods of mathematical statistics, the Student's T-test, the reliability was determined at p>0.05. Results: After the end of the pedagogical experiment, the students' performance improved on average in all classes. However, the improvement was uneven. Thus, the high increase in endurance was among schoolchildren from grade 2, grades 8-11 for boys, the indicators improved from 12 to 16% (p<0.05). The indicators improved by 12-15% (p<0.05) in girls from grades 2, from grades 9-11. Conclusions: As a result of the experiment, we can say that the sensitive period for the development of endurance in girls is the age of 8-9 years, 15-18 years, and in boys 8-9 years and 14-18 years. It should be noted that there is a high increase in endurance indicators in children aged 10-11 years. The results of the study make it possible to adjust the educational process in schools and improve the training process in various sports for children aged 7-18 years.
