Zbořilová, Martina ; Bačáková, Radka (advisor) ; Kračmar, Bronislav (referee)
Title: Kinesiological Analysis of the Rowing Stroke. Objectives: The aim of this thesis is to obtain, to analyse and process the data on the activity and involvement of selected measured muscles, working during one rowing stroke - in the drive part and in the recovery part. Methods: The work is processed by a kinesiological analysis of selected movement of the rowing stroke, based on the determination of muscle activation. Electromyography method was synchronized with the video recording. Results: Based on the sequences of the muscle activation was described their order and sequence in the actual shot of the rowing stroke (drive phase and recovery). We have proved that in the rigorous technical performance are always activated the same muscles in the exactly same order. Individual deviations from the correct technique in measuring appeared and thus enable their correction. Keywords: Electromyography, stroke, rowing, muscles.

Strusková, Edita ; Otáhal, Jakub (advisor) ; Michalec, Radim (referee)
Title: Effect of surface electrode type on quality of decomposition of surface EMG signal Objectives: The aim of this thesis is to evaluate the effect of surface electrode type, which was used for EMG record, on the quality of decomposition of surface EMG signal using decomposition software EMGlab. Methods: The form of the thesis is an experimental essay. It was detected an EMG signal from one healthy volunteer during mild cyclic contraction. It was used three different types of electrodes (standard surface electrode, tetrode, tetrode with saw-off spikes) for EMG signal detection. These signals were decomposed in program EMGlab. The results were processed in program MS Excel, compared with each other and graphically displayed. Results: The measurement verified a hypothesis which claimed that the used type of electrode affects the quality of automatic decomposition. The best results of automatic decomposition provide the signal gained from the standard surface electrode. Key words: action potential, decomposition, surface electrodes, EMG signal, tetrode, electromyography

Malý, Jiří ; Kračmar, Bronislav (advisor) ; Novotný, Petr (referee)
Title: Analysis of strenght training of rock climbers - campusing Objectives: The main objective of this work is to determine time and space characteristic of working muscle chains of upper body during training on campus board and climbing on vertical wall. Comparing basic exercise by measuring EMG signal in combination with cinematographic analysis synchronized with video record, to analyse coordination markers of muscle work in selected area of movement system. Methods: In our thesis we used a method of analysis and a method of comparison. We apllied the method of analysis in research of campusing movement and the method of comparison in comparing the basic climbing movement and basic campusing. Results: It is possible to define campusing as movement in vertical axis, which is executed by three times faster muscle chains activation compared to basic climbing on vertical wall. Movement is realized by upper limbs, by changing positions of one point holding position and two point holding position. In both activities measured muscles are wireing in similar mode, during campusing the musculus pectoralis major and the musculus triceps brachii are faster in start of their activity compared to climbing on vertical wall. Keywords: sport climbing, muscle chains, electromyography, campusing

Title: Analysis of electromyographic activity of selected muscles in exercises on selected balance surfaces. Objective: The objective of this dissertation was to document, compare and analyze electromyographic activity of m. gluteus maximus et medius, of m. erector spinae at the level L3 and of m. quadriceps vagus medialis et lateralis in exercises on selected unstable surfaces - on a cylindrical board and in balance sandals. Methods: The work was elaborated as a pilot study. Surface electromyography was used for objectification. The researched group consisted of 7 volunteers (5 women and 2 men), who had no serious injuries and surgeries in their anamnesis and none of them did any sports for a long period. Electromyographic activity of the above mentioned muscles was compared when doing two clearly defined exercises (stand on one lower extremity and hovering/gait on the spot) in balancing sandals and on a cylindrical board in sagittal plane. Results: The results only confirmed two hypotheses out of five ones. Namely it was the hypothesis no. 2 that the lowest activity of m. gluteus maximus was reached while doing exercise no. 3 - hovering/gait on the spot on a cylindrical board and the hypothesis no. 3 that the highest activity of m. erector spinae was reached while doing exercise no. 4 -...
