Title: Kinesiological analysis of selected techniques in greco-romain wrestling Objective: The aim of this Thesis is to measure the extent to which various muscles are involved during the practice of the wrestling technique body lock, lift and suplex. It also considers the order in which the muscles are involved. The research applies surface electromyography. Methods: The theoretical part of this Thesis is predominantly based on the method of analysis and synthesis of the specialized literature. In the practical part, the surface electromyography was used to measure which muscles are involved in the body lock, lift and suplex. Subsequently, the difference of the motion performance of the four probands was evaluated. Furthermore, the timing of muscle activation was monitored. Results: The evaluation of the result showed that musculus rectus femoris is the most involved in the movement and the least musculus obliquus externus abdominis. In addition, it was found that m. Obliquus externus abdominis is involved first, while the last one is involved with m. Biceps femoris. Key words: Wrestling, electromyography, quality of movement, muscle activation

Title: Comparative of muscle activity during the cycling step with the use of clipless and normal pedals. Objectives: Diploma thesis objective is to compare muscle activity during pedaling cycle with/without clipless pedal. Using EMG we want to establishe, if 6 chosen muscles are showing significant involvement difference for pedaling with/without clipless pedals. Methods: It is combination of empirical - theoretical thesis. Our work consists of intra- and interindividual comparative analytical study. We used two comparative methods for EMG signal evaluation - Pearson correlation coefficient and comparison with use of signed area of the region bounded by its graph. Results: The results of the correlation analysis show a high degree of compliance of the average normalized envelope diagrams for a cycling step with and without clipless. Based on the comparison of areas under the EMG curve, there is no higher muscle activation potential for the classic pedal. Keywords: cyclist, pedal, cycling step, muscle aktivity, electromyography

Title: The effect of breathing technique on intra-thoracic pressure, kinematics of barbell, and muscle activity during bench press exercise. Objectives: The main aim of this study is to determine relationship between breathing technique and bench press exercise. Furthermore, determine which breathing modification leads to overcoming highest resistance and how each individual breathing techniques (Valsalva maneuver (VM), Hold breath (HB), Lung packing (PAC), "reversed breathing" (REVB)) affects kinematics of barbell, and muscle activity, during different intensity (1 RM, 4RM, 8RM, 12RM). Methods: Experiment of cross-sectional character, with usage of our-calibrated sensor, for intrathoracic pressure measurements, 3D kinematics with passive markers and surface electromyography. For measuring anthropometric measurements was further used goniometer, digital scale, and measuring tape. Comparisons of the breathing techniques was done by analysis of covariance ANOVA, while particular parameters were compared by Pearson correlation. Results: Except of REVB technique, which indicated significantly lower load, there was no significant difference between techniques in lifted resistance. Similar effect was observed at results of intrathoracic pressure, where REVB technique showed significantly lower pressure,...

Title: Kinematic of cervical thoracic spine in the context of whole body posture Problematics: This work describes the kinematics of upper thoracic spine during specific movement of the shoulder girdle. The kinematic changes are evaluated with the relationship of the whole body posture. Aim: To develop the objective evaluation of the posture and the amount of the segmental spinal movement of cervical thoracic spine. To describe the relationship between the specific movement of arm - adduction and external humeral rotation - and the posture using 3D kinematic analysis. To objectify this tested movement as a diagnostic tool or a therapy for forward head posture. Methods: The theoretical part of this work summarizes the current knowledge of poor posture and there is defined the upright posture. The experimental part describes the measurement of the movement of shoulder girdle and its response to the axial system using 3D kinematic analysis. Result: The results of kinematic 3D motion analysis show that the external humeral rotation with adduction of the shoulder leads to the upright posture if there is the horizontal position of the thorax and pelvis. The posture was divided due to the physiological or pathological response with this simple movement. Conclusion: A new model for evaluation of the...

Headline: Swimming technique of physically disabled swimmers with unilateral above-knee amputation Aim of the Thesis: The aim of this thesis is to describe the intra-individual differences in the swimming technique of unilateral above-knee amputees by measuring the EMG of selected muscle groups. Methods: Surface EMG measurement in combination with using synchronized video recordings. Results: Research of the observed swimmers with unilateral above-knee amputation showed that: when swimming the front crawl, the swimmers unequally balance the intense kick of right and left leg mainly using the abdominal muscles and subsequently also in the electric potential of different sizes in other observed muscles; when swimming the backstroke, the upper body muscles on the side of amputated limb do not show any different activity than the muscles of the opposite side; when swimming the breaststroke, the main propulsion muscle for locomotion through the shoulder girdle - m. latissimus dorsi is activated for a longer period of time on the side of amputated limb; thereby, electrical activity of the selected muscles is not symmetrical in the timeline. Key words: swimming step, swimming, above-knee amputation, electromyography, muscle activity, handicap, EMG.

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...

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.
