Influence of Motor Stereotypes on the Quality of Musical Performance and Musculoskeletal Disorders in Keyboard Players
 LECHNER, Jan
Music has long been associated with human society. The positive benefits of performing music on human beings have long been known. Increased attention has been paid to its risks recently. The negative effects of a sedentary lifestyle on the human locomotor system are discussed a lot. Nevertheless, most musicians play sitting while they can stand. The aim of this bachelor thesis was to describe the influence of motor stereotypes on the quality of music performance and development of musculoskeletal pain, and to compare the motor stereotypes of keyboard players during standing and sitting. In the theoretical part the basic knowledge about this topic is summarized. Functional description of the human locomotor system and the influence of music is provided. Both motor stereotypes that can lead to playing-related musculoskeletal disorders and physiological motor patterns are described. Music physiology and musician's medicine are also presented. The practical part of the bachelor's thesis consists of combined research consisting mainly of recording the electromyographic activity of selected muscles during performance in standing and sitting positions. The activity of the following muscles was measured bilaterally: extensor carpi radialis, trapezius descendens, pars lumbalis erectoris spinae and obliquus abdominis externus. The performance quality was evaluated both subjectively and the software analysis of audio recordings was performed. Furthermore, kinesiological examinations were performed on the probands. In addition, an online questionnaire survey was included. Mainly the results of electromyographic measurements favorize slightly the standing position for playing instruments. This work can be used in the clinical practice of physiotherapists and in the musician's medicine. It can also serve music educators and musicians themselves

Results of one-sided endurance of a kinetic apparatus in volleyball players and possibilities of a therapy
 CHALUPOVÁ, Andrea
The one-sided load of volleyball players leads to occurence of pathokinesiologic changes of the locomotive system. The objective of the bachelor thesis is to ascertain whether volleyball players suffer from locomotive system disorders due to the one-sided overload and whether it is possible to make up a uniform compensatory set of exercises as a therapy. The objective of the theoretical part is to ascertain what functional disorders of the body system occur in connection with the one-sided load of volleyball players, what muscular dysbalances accompany the disorders and what physiotherapeutic procedures can influence them. The objective of the practical part is to use the obtained theoretical findings as the basis for making-up a set of compensatory exercises as a proposed therapy applied within the scope of case reports. The practical part involved a qualitative research using the techniques of interviews and observation, and included two case reports of randomly selected professional volleyball players. Examination of the probands has confirmed the one-sided load of the locomotive system manifested in insufficiency of the deep stabilization system and functional disorders in the area of the shoulder joint. Focused on activation of the deep stabilization system and including shoulder-blade stabilization features, two individual therapeutic plans were made up and undertaken by both the probands in accordance with the charakter of the specific movement activity of volleyball players. The final examination has shown objective improvement of the function of the posture stabilization system of one of the men. Activation of the deep stabilization system with stabilization of the shoulder joint within the specific movement activities of volleyball players appears to be a suitable basis of the compensatory exercises preventing the one-sided load of the locomotive system. The therapy requires an individual approach. For further research in this area I propose measurement of the muscular actvity by means of electromyography and focusing on co-activation of stabilizers of the shoulder joint within the specific movement activity of volleyball players.
