Abstract
Introduction: The spine’s significance in postural assessment is so substantial that postural status can be judged primarily through spinal alignment. Posture ioned centrally, the spine maintains body balance. Three major body segments—the head, thorax, and pelvis—must remain balanced, a function achieved exclusively by the spine through its structure and natural curvatures. Consequently, the spine is the cornerstone of posture, directly or indirectly connected to all skeletal components, and supported by major back muscles responsible for upright posture. Therefore, postural integrity depends on spinal health and muscular balance. Aims: Examine the effect of a proposed preventive exercise program on improving the strength of selected muscle groups supporting the spine, thereby preventing spinal postural deviations among female students in the first cycle of basic education (ages 6–9). Enhance the functional efficiency of spinal-supporting muscles and prepare them for subsequent developmental stages. Methodology: The experimental method was employed using pre- and post-measurements due to its suitability for the nature of the study.The study population consisted of female students in the first stage of basic education in Bani Walid, aged 6–9 years, with a total population of approximately 120 students.A purposive sample of 14 female students aged 6–9 years was selected from Al-Salam Basic Education School in Bani Walid, based on the following criteria: Free from postural deformities and abnormalities. Free from organic diseases. Availability and ease of communication with the researcher. Consent of students and approval of their parents. The sample was divided into two equal groups: Experimental group: 7 students subjected to the proposed exercise program. Control group: 7 students subjected to the regular physical education curriculum. Conclusions: Based on data analysis and discussion of results, the following conclusions were drawn: 1. Statistically significant differences were found between pre- and post-tests in back muscle strength (trunk lift test) in favor of post-measurements for the experimental group. 2. Statistically significant reductions in postural deviation levels were observed in the experimental group. 3. Significant improvements in spinal flexibility were recorded in favor of post-measurements. 4. Significant improvements in functional efficiency questionnaire results were observed for the experimental group. 5. A significant increase in daily physical activity levels was recorded for the experimental group. 6. The proposed preventive program demonstrated high effectiveness in improving muscular strength, posture, and reducing postural deviations. 7. Preventive training programs targeting core muscle strengthening represent an effective strategy for preventing and reducing postural deviations in school-aged children.
