Hons, Ondřej ; Žáková, Lenka (advisor) ; Nováková, Tereza (referee)
Title: Influence of dynamic stretching on the resulting dynamics of lower extremities in volleyball Objectives: The aim of this work was to find out if there is a correlation between long term dynamic stretching and muscle dynamics of lower limbs of volleyball players. Methods: Theoretical part is based on foreign literature and researches. To gain the necessary data, experimental study was created. It contained 10 male probands in the age of 16-19. In the beginning of the experiment, all the participants attended the Bosco test at the biomedical lab at UK FTVS. The main parameter was the total flight time of the entire 60 seconds. After that participants attended 8 weeks of 2 times a week of dynamic stretching before the training instead of their usual stretching stereotype. Immediately after those 8 weeks, second Bosco testing took place and the comparison of the data of the whole group and individuals was made from the view of their volleyball posts. Results: There was a slight improvement in all the data at the whole group and significant improvement in anaerobic endurance. After comparing of the results of all the probands no significant differences between the probands from the perspective of player's volleyball posts. Keywords: volleyball, stretching, static stretching, dynamic stretching,...

Elektromyographic analysis of differences in selected excercises on pommel horse and riding horse
Pyšková, Barbora ; Nováková, Tereza (advisor) ; Žáková, Lenka (referee)
Author: Bc. et Bc. Barbora Pyšková Title: Elektromyographic analysis of differences in selected excercises on pommel horse and riding horse Objectives: The aim of the thesis was to measure the activity of selected muscles, expressed as the percentage value of the maximal voluntary contraction (MVC), during excercises performed by both males and females probands. The effect of treatment (on pommel horse vs riding horse) and proband sex on muscle activity was tested. Methods: Maximal voluntary contraction of each muscle (eight in total) was electromyographically measured in each proband, using the test according to Janda. These values were used as a standard to which the values obtained by excercising on pommel horse and riding horse were related. The values were averages of three repeated measurements. The effect of studied factors was tested by analysis of variance. Results: The tested hypotheses were confirmed. The muscle activity during excercises was statistically significantly affected by the factors studied, therefore the variation in measured values is not random. Muscle activity tended to be higher on riding horse than on pommel horse, and in females compared to males. Key words: horse riding, pommel horse, EMG, electromyography, hipotherapy, correct horse sit

Study of secretory granules from insulin-producing tissues and cell lines.
Halušková, Petra ; Žáková, Lenka (advisor) ; Koblas, Tomáš (referee)
Pancreas is known to be an organ producing a variety of exocrine and endocrine substances, where also insulin belongs. This hormone is produced in the body almost solely by specialized β-cells of the Langerhans islets and is stored here in secretory granules. As the β-cells contain large number of these vesicles, an organism can quickly respond to the glucose stimulation. Completely processed insulin is formed in the secretory granules probably as a hexamer, where six insulin molecules are coordinated along two zinc bivalent cations. Appropriate β-cell response to higher glucose level and following insulin secretion is one of the key processes that regulate metabolism in the body. In order to study insulin production, its effects or secretion, permanent pancreatic cell lines are often used as biological models, out of primary cells from islets of Langerhans. This diploma thesis is focused on two permanent cell lines INS-1E and BRIN-BD11. We searched for the ability of the cells to produce insulin, if the hormone is fully processed, as well as zinc content, which could have a great influence on insulin's processing. Using different methods we compared these two cell lines with cells from the Langerhans islets. We succeeded in isolation of secretory granules from all three cell types and we plan to...

Clinical Effectiveness of the Schultz Autogenic Training on the Electrical Activity of the Brain
Andová, Veronika ; Žáková, Lenka (advisor) ; Stupková, Michaela (referee)
Title of thesis: Clinical Effectiveness of the Schultz Autogenic Training on the Electrical Activity of the Brain Objectives: The thesis aims to analyze the impact of Schultz autogenic training on brain activity evaluated using EEG Course of action: To obtain the data, an experimental group containing 11 participants aged 20-30, disregarding gender, was created. Participants practiced Schultz autogenic training using the identical audio record once a day during the course of nine weeks. Upon completion of the training, all participants were subjected to one-off measurement by the Nicolet EEG instrument. Brain activity was measured before, during and after the training. Obtained EEG data were processed with NeuroGuide software using coherence analysis and fast Fourier transform. Coherence analysis provided charts mapping the electrical activity of Brodmann areas during the course of all three stages and fast Fourier transform yielded data of performance ratio between theta and alpha frequencies, so called T/A index. Performance ratio of the T/A index was subject to Student's paired t-test in order to draw final conclusion. T/A results show changes in the representation of alpha and theta waves during all measurements. Results: The results of the thesis were used to verify the veracity of stated...

The effect of shoulder girdle stabilization exercises on muscle activity during direct impact in rugby players with subacromial impingement syndrome
Chytilová, Martina ; Šťastný, Petr (advisor) ; Žáková, Lenka (referee)
Title: The effect of shoulder girdle stabilization exercises on muscle activity during direct impact in rugby players with sub-acromial impingement syndrome Objectives: Comparison of muscle activity during direct impact while performing the rugby tackle to tackle bag and to player using electromyographic amplitude analysis before and after intervention programme for players with subacromial impingement syndrome (SIS). Application of intervention programme consisting stabilization excercises for shoulder complex and activation of deep stabilization muscles of the spine. Methods: Theoretical part contains topics about shoulder girdle, rugby and rugby injuries, mainly subacromial impingement syndrome. Mentioned issues are included into the thesis due to the research of current literature from international sources and studies. Practical part regards the aplication of three-months long intervention programme for eight players at junior national level with diagnosis of SIS, when pre-testing a post-testing is realized by clinical tests and EMG measurement. Assessment of enter and control examination is realized with analysis of variance ANOVA. Results: Intervention programme was sufficient for changes in EMG amplitude for two muscle groups in rugby players with SIS. Hypothesis comparing the EMG measure...

Influence of a complex stretching exercise of lower limb on postural stability
Maier, Ludvík ; Žáková, Lenka (advisor) ; Vomáčková, Helena (referee)
Title: Influence of a complex stretching exercise of lower limb on postural stability Objectives:: The main objective of this diploma these is to find out, using dynamic computerized posturography, whether the increased mobility of the lower limbs has a positive influence on postural stability. Another partial objective is to determine efficiency of the practised stretching exercises. Methods: This is a pilot study where in research participated five probands whose measurement results were evaluated qualitatively. The aged of probands at the time of the first measurement was from 13 to 18 years. All probands are male volleyball league players and during the last two years occurred to a marked grow by all of them. Given their tall stature, it was expected a decrease in the mobility of the lower limbs and muscle shortening. To the data acquisition was used clinical examination of active range of motion and shortened muscle testing according to Janda. Postural stability was measured using computerized dynamic posturography SMART EquiTest System from Neurocom. Measured data were processed using the program NeuroCom Balance Manager software. In the Framework of study were conducted two intrumental measurements in the range of two months. After the first measurement all probands were instructed how to...

Systhesis and Characterisation of the Insulin-like Peptide 5 from Drosophila melanogaster
Halušková, Petra ; Žáková, Lenka (advisor) ; Poljaková, Jitka (referee)
Many evolutionary conserved proteins and mechanisms have been observed in nature, one of them is insulin and its signal pathway. Importantly, many parts of this pathway in humans are similar to those found in lower organisms, such as fruit fly (Drosophila melanogaster). Insulin is one of the most studied complex molecules; it acts primarily as a hormone but it can also act as a growth factor due to its evolutionary congeniality and similarity to the IGF. It has long been unclear how insulin binds to its receptor and how insulin or insulin-like proteins influence regulation of metabolism, cell proliferation, cell growth and also the size of organs and the whole body. Examining insulin-like peptide superfamily and its signal pathway in invertebrates may thus be used to better understand many metabolic processes in vertebrates thanks to high evolutionary conservation. In this thesis, we tried to prepare an analogue of insulin like peptide 5 (DILP5) of Drosophila melanogaster by a total chemical synthesis. This analogue is composed of A-chain of human insulin and B-chain of DILP5. In B-chain all methionins were replaced by amino acid norleucine using a chain combination method through S-sulfonate forms of each chain. The results show that this protein can be successfully prepared, however, the amount...

Mention Metanoia in Pastoral and Social Work
Kerepecká, Jana ; Milfait, René (advisor) ; Žáková, Lenka (referee)
This bachelor thesis deals with the term metanoia, which can be replaced by the more familiar term conversion. It is a decision for a radical change of life, which involves the whole person and leads to transformation and new orientation of values and standards. It is about turning away from the current way of life and turning to God. This is a personal response to God's invitation to his fellowship. The aim of this thesis is to describe the process of conversion and put it into the context of selected areas of social and pastoral practice. The first part deals with the essence of conversion and the question what conversion brings. In the second part, some of the stories of biblical figures from the Old and New Testament are analysed. The process of metanoia and its aspects are well captured in this stories. Finally, the third and the fourth parts are devoted to the meaning of metanoia for pastoral and social practice. It is shown that just here metanoia has its place.
