Chrástková, Martina ; Kračmar, Bronislav (advisor) ; Jandová, Soňa (referee) ; Dvořák, František (referee)
Title: The reflection kinesiology analyse of cross country skiing Purposes: To compare coordination of chosen muscles on leg during reflection of cross country skiing classic technique, skating and herringbone. Methods: Comparative analysis: the dates were measured by surface electromyography and 2-D video-analysis. Results: We founded statistical significance by comparisons muscle activation on right leg during kick during cross country skiing: classic technique, diagonal stride and herringbone and V-1 skating and herringbone. In case the left leg the statistical significance was disprove by: m. peroneus longus sin during comparison of diagonal stride and herringbone and m. gastrocnemius medialis sin V-1 skating and herringbone. We founded high level of laterality of diagonal stride and herringbone. In case V-1 skating, the significant similarity was not founded for m. vastus lateralis and m. gluteus medialis. Key words: Cross country skiing, classical technique, skating, herring bone, kinesiology, surface electromyography (EMG), muscles activation

Kinesiological analysis of locomotion in the shoulder girdle during Nordic Walking.
Mikulíková, Petra ; Kračmar, Bronislav (advisor) ; Véle, František (referee) ; Tošnerová, Vlasta (referee)
Title: Kinesiological analysis of locomotion by shoulder girdle during Nordic Walking Aim: The purpose of this work is to subscribe kinesiological coordination between shoulder and trunk muscles during uphill Nordic Walking and free walking. Methods:The study has the character of primary analytical study of two evaluation in the form of inter- and intra-individual analysis. The group of ten Nordic Walking instructors measurements were carried out using surface electromyography synchronized with video.The data were processed in Matlab and DartFish. From the processed outputs could be visible the timing of muscles and its changes in specific movements. And also is visible the range of movement in the shoulder and elbow. The outputs were compared with expert knowledge in a field of physiotherapy. Result: Results showed that the timing of muscles during Nordic walking and free walking uphill is different. It showed a certain regularity in the muscle involvement, mainly in Nordic Walking and greater individuality in the involvement of individual probands during free walking. Conclusion: Conclusions describe a muscle coordination during the activity of Nordic Walking and free walking. Nordic Walking is recommended as an appropriate physical activity for human musculoskeletal system. Keywords: walking,...

The influence of imagination on the performance of white water slalom racers
Vondra, Jan ; Bílý, Milan (advisor) ; Kračmar, Bronislav (referee)
Title: The influence of imagination on the performance of white water slalom racers Tasks: The main task of this work is to find out if imagination can influence the performance of racers. Techniques: We used the technique of observing the coexistent relation by correlation analysis. At first we measured the time that is necessary to visualize and complete the course in one's mind and then compared it to the actual race time. Results: In the surveyed group of men (N = 11) only a slight association between performance and imagination was observed. In the group of women (N = 4) there was a more significant relation between performance and imagination. Key words: White water slalom, imagination, visualization, performance in sport.

Analysis of strenght training of rock climbers - campusing
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

Comparative analysis of selected soccer kicks
Řebíček, Pavel ; Kračmar, Bronislav (advisor) ; Buzek, Mario (referee)
Title: Comparative analysis of selected soccer kicks Objectives: The main objective of the study is to characterize the involvement of selected muscles during soccer kicks by time and space and subsequent comparison with specific exercises with expander by EMG measurement. Methods: The study has a character of a case study, comparative analysis of relative timing of movement and activity of selected muscles during soccer kicks by surface poly-electro-myographical analysis and kinematic analysis. Results: Timing of muscles involvement during soccer kicks is different than timing of muscles involvement during exercise with expander. Keywords: EMG, soccer, kick, muscles, activation

Kinesiological Analysis of the Rowing Stroke
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 received data about the activity and involvement of the selected measured muscles, working throughout one cycle of the rowing stroke - in the course of the drive phase and during the recovery part of the stroke as well. 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, rowing, muscles, stroke.

Bačáková, Radka ; Kračmar, Bronislav (advisor) ; Kučera, Miroslav (referee) ; Zounková, Irena (referee)
Tittle: Description quadrupedal locomotion diagonal pattern in specific sport activity (rope climbing, walking, pull-up) Aim of work: The aim is to find a description kvadrupedal locomotion diagonal pattern with rope climbing and its motion pattern compared with the motion pattern of walking and pull-up. Methods: This work is descriptively-association study with quantitative and qualitative analysis. The dates were measured by surface electromyography and 2-D video-analysis. Results: Alternating activation of upper extremities (rope climbing without the lower extremities), we proved that the movement supporting lower extremities is quadruped locomotion diagonal pattern. Symmetric work of upper extremities (pull-up) is not in response at lower extremities quadruped locomotion diagonal pattern. Key words: Electromyography (EMG), quadruped, diagonal pattern, rope climbing, pull-up, walking
