The Spinal Column State of Adolescent Boys of Different Levels of Physical Activity // Stanje kičmenog stuba dečaka adolescentnog uzrasta različitog stepena fizičke aktivnosti

Abstract

The sedentary form of behaviour, the effective holding of the body are potential causes of the formation of muscular asymmetries, and thus of poor body posture. The aim of the paper is to determine the differences in posture of children of different levels of physical activity. The research involved an assessment of a sample of 42 handball players 13.02 ± 0.89 years and 32 non-athletes 13.16 ± 0.88 years. Three tests were used to evaluate the presence of poor posture, to evaluate the scoliotic poor posture - Adam’s forward bend test, to estimate the kyphotic poor posture –Reclination test with the contraction of the extensor muscle to assess the lordotic poor posture – Contraction test of the abdominal muscles. The obtained results of the chi square of the test indicate that there are no statistically significant differences between the analysed groups of subjects regarding the presence of the scoliotic (p = 0.85), the kyphotic (p = 0.77) and the lordotic poor posture (p = 0.82) between the defined groups. The assumption is that boys are involved in sports activities due to the impaired posture in adolescent age, in order to prevent further progression and formation of new bodily deformities and to avoid similar conditions.
