When athletes enter professional activities, they may face abnormalitieswhich are variable depending on the type of sport activities. Forward head,shoulder mal-alignments and spinal column are the main posturaldeviations in athletes with overhead activity. These abnormalities makeathletes prone to injury. This research was conducted with 68 athletes fromMES KERMAN, STAR FOROUGH KERMAN and SAMENOL HOJAJMASHAD teams who were selected by accessible method. The subjects weredivided into two groups: injured (N=40, age=24.27±4.43 yr, height=186.55±7.24 cm, weight=85.17±10.06 kg) and healthy (N=28, age=23.85±3.82yr, height=183.67±8.36 cm, weight=82.32±9.27 kg) using exclusioncriteria. To assess forward head, a goniometer was used; to assesskyphosis, a flexicurve and to assessment ROM, Leighton flexometer wereused. To study subjects' injuries, self-report injury form was used. Datawere analyzed with SPSS20, independent t test and Pearson correlationcoefficient (P0.05).The results showed a significant difference in angle ofkyphosis curve (P0.013) and forward head (P0.001) between healthy andinjured handball players. Also, there was a significant difference betweenthe angle of kyphosis curve and ROM of internal rotation of dominant hand (r=0.72, P0.001), external rotation of dominant hand (r= -0.48, P0.002),internal rotation of non-dominant hand (r=0.79, P0.001), external rotationof non-dominant hand (r= -0.42, P0.038) and shoulder joint of injuredhandball players. It can be concluded that if athlete enter professionalsports and repeatedly train the specific skills, it may cause posturalabnormalities and injury. These abnormalities cause kinematic changes injoints. |
