This article examines postural development and musculoskeletal strengthening in primary school children aged 7–10, a period marked by rapid anatomical and physiological growth. At this stage, the spine and musculoskeletal structures are still developing, which makes children particularly vulnerable to postural deviations such as kyphosis, lordosis, and scoliosis. Factors including prolonged sitting, improper desk ergonomics, heavy schoolbags, and extended screen time significantly contribute to the onset of these conditions. Epidemiological studies indicate that approximately 25–40% of children in this age group display early signs of postural abnormalities.

The article highlights the importance of early preventive strategies—such as targeted physical exercises to strengthen core and back muscles, ensuring ergonomic classroom environments, and educating children about correct posture and movement habits. These interventions have been shown to reduce the risk of later spinal deformities and promote healthier physical development.

In conclusion, the study emphasizes the need for coordinated efforts among teachers, parents, and healthcare professionals to monitor posture, encourage regular physical activity, and create supportive conditions that foster optimal musculoskeletal growth during the primary school years.
