The Influence of Sports on the Resistance to Educational Stress of the Body of Students

Introduction. The search and scientific substantiation of technologies and conditions for the formation of students' body tolerance to educational loads is an urgent problem in the preventive field of school medicine.

Aim. The aim of the study was to evaluate the impact of sports activities in sports sections on the frequency of complaints among students in grades 5‒9 about weakness and fatigue after lessons.

Materials and methods. An online survey of 60,753 students in grades 5‒9 from 25 regions of Russia was conducted. The children answered questions about the frequency of complaints of weakness and fatigue after lessons, depending on whether they play sports or not. The relative risk (RR) and etiological proportion (EF) values were calculated to assess the causation of frequent complaints due to lack of exercise.

Results. It was found that 27.9% (95% CI: 33.9–34.6) of students often complain of weakness and fatigue after school, 37.9% (95% CI: 37.5–38.2)―sometimes and 34.3% (95% CI: 33.9–34.6)―never or very rarely. Among those who are not engaged and engaged in sports , the number of children with frequent complaints in the 5th grade was 20.7% (95% CI: 19.6‒21.7) and 16.2% (95% CI: 15.3–17.1) (p <0.05), respectively, in the 9th grade―37.3% (95% CI: 36.1–38.6) and 28.3% (95% CI: 27.2–29.5), respectively (p <0.05); 17.6% (95% CI: 17.2–18.0) of boys and 36.0% (95% CI: 35.5–36.5) of girls reported frequent complaints (p <0.05). The analysis of the values of RR and EF made it possible to establish the conditionality of increasing the resistance of the body of students to educational loads by playing sports in sports sections.

Conclusion. The data obtained indicate a higher level of resistance to the educational stresses of the body of students involved in sports sections. Further research in this area will make it possible to recommend to children with learning difficulties those sports that will contribute to the prevention of their health disorders in the educational process.
