IMPROVEMENT OF POSTURE IN PRIMARY SCHOOLCHILDREN AT PE LESSONS

Abstract

Aim. To improve the physical development and posture of primary schoolchildren during physical education lessons at a modern Moscow full-time school. Materials and methods. The study was conducted at a secondary school in Moscow (for 3.5 months) and involved 86 schoolchildren, of whom 41 were girls and 45 were boys (grades 1–4). Study methods included anthropometric measurements (body weight, body length), trunk muscle endurance tests, and photometric measurements of posture (only for schoolchildren grades 2–4, the PostureScreen Mobile app). Statistical analyses were carried out with the Mann – Whitney t-test. Results. Special physical exercises developed by the authors for PE lessons significantly improved the static endurance of the trunk muscles. In girls and boys, the results obtained for different muscles improved from 108.6 % to 231 % and from 191 % to 308.6 %, respectively. A significant decrease (p ≤ 0.05) was recorded in the head tilt index in the frontal and sagittal planes. Conclusion. PE lessons proposed by the authors resulted in a significant improvement in the static strength endurance of large trunk muscles and photometry measurements.
