Title: The effect of shoulder girdle stabilization exercises on muscle activity during direct impact in rugby players with sub-acromial impingement syndrome Objectives: Comparison of muscle activity during direct impact while performing the rugby tackle to tackle bag and to player using amplitude analysis of electromyographic signal (EMG) before and after intervention programme for players with subacromial impingement syndrome (SIS). Application of intervention programme consisting stabilization excercises for shoulder complex and activation of deep stabilization muscles of the spine. Methods: Theoretical part contains topics about shoulder girdle, rugby and rugby injuries, mainly subacromial impingement syndrome and electromyography. Mentioned issues are included into the thesis due to the research of current literature from international sources and studies. Practical part regards the aplication of three- months long intervention programme for eight rugby players at junior national level with diagnosis of SIS, when pre-testing a post-testing is realized by clinical tests and EMG measurement. Results: Intervention programme was sufficient for changes of EMG amplitude values expressed as percentage of maximal voluntary isometric contraction (MVIC) in some of rugby players with SIS only for some...

Thesis title: Effect of targeted training of the lower scapular fixators on the shoulder girdle function of rugby players The concept of the problem: Rugby is one of the toughest ball sports and there is no shortage of injuries. In addition, injuries in the shoulder area are among the most common and any possibility of reducing these injuries is beneficial. There is not much time left for compensation and targeted intervention; moreover, it is not usually led by physiotherapists but by fitness coaches and only in larger clubs. The consequence is a muscle imbalance in the shoulder girdle, which can result in the so-called scapular dyskinesis. This is turn affects the function and stability of the shoulder joint not only by the overhead athletes. It is possible to influence scapular dyskinesis in various ways. One of them is the inclusion of targeted training of lower scapular fixators into fitness training and thus their stability is improved. Objectives: The main aim of this thesis is to verify whether rugby players with painful shoulder have sufficiently scapular fixation based on kinesiological and biomechanical knowledge. Another aim of this thesis is to create such an exercise unit that would ensure the correct activity of the lower scapular fixators and verify this by measurement. The final...
