This doctoral thesis deals with the kinesiological analysis of the athletic run - sprint. The aim of the thesis is the time characteristics comparison and switching on of the muscles which are working during the sprint before and after the performance of special running exercises. It is becoming much more important to use the special training procedures during training sessions. The special running exercises are performed almost daily during training sessions of sprinters. The question is to what extent their performance is evident on the activation of muscles. The qualitative and quantitative results show the activation of muscles during sprint before and after the performance of the special running exercises. The main tool of the research was the surface EMG analysis of muscles during a 30-metre long sprint. The content of the research were two comparative analysis, where 8 proband participated - interindividual and intraindividual. During the evaluation process we considered the quantitative and qualitative components. On the basic of the reached results we may say that there is no diference between the run before and after the performance of special running exercises. Keywords: Sprint, special running exercises, electromyography, ANOVA

Thesis title: Electromyographic Analysis of the Shoulder Girdle Muscles Inclusion of Volleyball Players Problem definition: Elite sport is very demanding, not only physically, but also mentally. The demands on the musculoskeletal system are often not compensated, especially in children and junior categories. The only targeted and regular compensation takes place at volleyball by the fitness training in the gym, but not always properly lead and adapted to the individual needs of athletes. The question is whether it is possible to prevent these problems. From my perspective, yes, the inclusion of appropriate compensation exercise in normal training session, which will require little equipment and time and to be functionally connected with volleyball technique that players do not lose the game performance. In the context of the thesis will be compared exercising of the second diagonal PNF for the upper extremity with an elastic resistance and simulated strike without the ball - volley lob, as an alternative fitness of exercises for volleyball players. Objectives: The aim of the dissertation is based on the available literature to outline the issues of kinesiological and biomechanical relationships of the shoulder girdle in sports especially in volleyball, which is a typical representative of the...

Tittle: Comparative analysis of addirect forward stroke perfomed on single canoe in flatwater canoeing and in paddle pool. Goals: The goals of study is to describe and compaq the movement pattern of a forvard paddle stroke on a canoe in flatwater and in the paddling pool. Methods: The work has mixed empirical-theoretical character, The study is a descriptive individual study. Muscle activity was measured using surface electromyography with synchronized video recording (kinematic analysis). Results: We found differences in muscles involved in the direct paddle stroke forward on canoe and paddle pool. The main differences are, that on the water the boat goes to the paddle and in the paddle pool, we push the water around us.In the first case the athlete push the boat towards to the paddle. However in the paddle pool the athlete just pulls paddle through the water. Another important difference is, that in the paddle pool we do not develop the "water feeling" and in the paddle pool does not have to keep balance. Canoeist is on solid grand all the time. For the winter season, we can recommend a paddle pool as a specific strengthening, but the paddling or ride on water on water does not replace it. Key words: Flatwater canoeing, paddle pool, elektromyography, forward stroke, canoe

Title: Electromyographic analysis of mutual relation between standing and movement pattern in shoulder girdle Objectives: This thesis examines the electric activity and recruitment (timing) of m. latissimus dorsi, m. obliquus externus abdominis, m. gluteus maximus, m. tensor fasciae latae, m. tibialis anterior, m. erector spinae and m. trapezius during shoulder girdle movement standing on both feet, ipsilateral or contralateral foot. Furthermore the thesis explores whether it is possible to objectify the existence of published tendomuscular chains or the whole hypothetic Latissimus dorsi muscle chain of Spiral stabilization concept using surface electromyography. Methods: The muscles mentioned above were measured bilaterally with surface electromyography electrodes during particular movements. Twelve healthy individuals participated, seven women and five men in the age of 23 - 30. All participants were instructed to do the specific movement from Spiral Stabilization concept against the 2kg resistence of elastic rope when standing on both feet or in one leg stand on contralateral or ipsilateral leg. Results: We can identify muscles that are active in the particular movements almost within all participants, that are activated less often and those that are involved rarely. But we are not able to...

The Master’s thesis describes electromyographic methods and it is focused on one of them - myofeedback. There are described principle, realization and application of myofeedback in this thesis. There is explained positive influence of using therapeutic games in therapeutic process. The diploma thesis deals with a realization and description of MFB-Amos apllication which allows to upgrade an electromyograph by myofeedback enabling of using the therapeutic games. Application allows measure of EMG signal and consecutive analysis, and offers three therapeutic games.

This thesis explains structure of skeletal muscles, generation of action potencial and principle of muscle contraction. Further it shows types of electromyographic signal recording and its usage in therapy. Technical aspects of EMG signal and components required for electromyograph assemblage are next topic of this thesis. Another part presents design of simple EMG module for therapeutical application with bluetooth 4.0 interface.

Bei der Durchführung von Studien mit dem Elektromyografie-(EMG-)Verfahren müssen diese auf eine Bezugsgröße normalisiert werden, um eine Vergleichbarkeit mit anderen Messungen zu ermöglichen. Bei statischen Messungen wird sehr häufig die Maximalkraftmessung MVC zur Normalisierung genutzt. Dieses Verfahren basiert jedoch auf statischen Postionen und scheint daher ungeeignet bei der Messung von Bewegungen. Daher wurde im Rahmen der Untersuchung dynamisch-muskulärer Beanspruchungen ein neuartiges Normalisierungsverfahren „normalized standard movement (NSM)“ entwickelt, das mit diesem Beitrag vorgestellt wird. Es wird gezeigt, dass das Verfahren methodisch an dynamische Messungen angepasst ist und dass die Streuung sowohl der Kraft- bzw. Momentwerte als auch der elektrischen Aktivitäten im Vergleich zu MVC/MVE-Messungen erheblich geringer ist.

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: Comparative analysis of the kayak forward stroke Objectives: The aim of this study is to describe and to compare the kayak forward stroke performed in the pool with countercurrent and on the flat water. Methods: The research was conducted in an intentionally chosen sample of eight kayakers with high level of performance in whitewater slalom. We watched activity of twelve selected muscles during kayak forward stroke performed in the counterflow pool and on the flat water by surface electromyography and kinematic analysis. Study evaluates intraindividual and subsequently interindividual muscle timing and the size of the muscle activation due to maximal voluntary contraction. Results: The results proved the same timing of muscles in counterflow pool and on flat water. The muscle activity in the counterflow pool was bigger than on flat water. Key words: kayak, counterflow pool, surface electromyography, paddling

Title: Walking step coordination characteristic comparison for walking on running simulator and off-road walking. Objectives: Goal of the thesis is to measure, analyze and evaluate data of activity and involvement of lower limb muscles for offroad walking and walking on running simulator. The measured characteristic will be intra-individually and extra-individually compared. Method: Surface polyelectromyography method for data measurement and kineziological movement analysis method for values comparison are used in the thesis. Ten muscles of lower limb (2  5 muscles on left and right lower limb) were chosen. Results: Ten lower limb muscles were chosen and their activity for walking on running simulator and offroad walking was measured by surface polyelectromyography method on ten sportsmen. The results indicate that chosen muscles participate on monitored movement. The analysis shows that the muscles activity follows the same order for each of tested sportsmen independently on the external condition (running simulator and offroad walking). The thesis that correlation of measured values is higher for running simulator have been confirmed. But m.gluteus.med. and m.glut.max. have variation in the activity of the involvement in the field and on the treadmill. Similar results have also m.vastus med....
