【 摘 要 】

The aim of study was to find out the current level of musculoskeletal system in younger school age pupils with intention of body posture and muscle balance, including the physical activity, within physical regimen. The monitored group consisted of 90 pupils in younger school age, of which was 51.1 % (n = 46) girls (body height 139.46 ± 3.9 cm, body weight 34.12 ± 3.1 kg) and 48.9 % (n = 44) boys (body height 138.63 ± 3.8 cm), body weight 33.2 ± 2.6kg) of the town - Trenčín. The mean age of pupils was 8.67 ± 0.6 in girls and 8.3 ± 0.9 in boys. In terms of evaluation methods of selected factors, within the musculoskeletal system, we used standardized methods for physical practice. In order to obtain data and information about physical activity, we used the non-standardized survey, which was based on the needs of study. The obtained results pointed to the below facts. Up to 48 % of girls and 50 % of boys had poor body postures. There was no significant difference between genders (p > 0.01). The significant difference was between the genders, within the different areas of body postures, mainly in spine curvature (χ2 p < 0.05) and in position of shoulders and scapulas (χ2 p < 0.05), as the boys were evaluated with points 2. The most significant difference of shortened muscle groups was between the girls and boys in m. pectoralis major (χ2 p < 0.01) and m. tensor fasciae latae (χ2 p < 0.05). We found that in boys was dominance of weakened muscle groups, such as m. abdominis, m. trapezius pars descendens (lower part of trapezius muscle) and fixators of scapulas (χ2 p < 0.01). The weakening of m. gluteus (χ2 p <0.05) and deep flexors of head and neck was characterized in the increased standards in girls. On average, the girls spent 90 minutes and boys 127 minutes per week of doing physical activities, as the difference was 37 minutes (χ2 p < 0.01).
