Compensatory intervention exercise program for volleyball players
VANDASOVÁ, Tereza
The topic of this bachelor thesis is a compensatory intervention exercise program for volleyball players. The final work is divided into theoretical and practical part. The theoretical work describes the game of volleyball, anatomy of the knee joint and women in sports. This theory is used in the practical part. The players of the volleyball team SK Hlincovka aged 17-18 were selected for the research. Based on my own experience, I know what game activities cause knee injuries. The most common reason for injury is poor or completely missed stretching before and relaxation after training or a match. The aim of the work was to create a compensatory intervention movement program focused on overloading the knee joints in volleyball toys using yoga exercises. Respondents received a compensatory intervention exercise plan and five questions to answer. The first question concerned daily exercise in the current epidemic situation. Only 41.18% of respondents answered that they exercise regularly every day. The second question focused on the most and least popular exercise of the compensatory intervention exercise plan. Most players, i.e. 29.41%, agreed that they like exercise number 5 the most. On the other hand, more than half of the respondents, i.e. 52.94%, do not like exercise number 9. For the third question, concerning the disappearance of knee pain during a volleyball break, the players had a choice of three answers, with 50% of respondents choosing the answer " B "and replied that the pain had disappeared and they only felt it exceptionally. For the fourth question, concerning the observed changes in the knee joint, they again had a choice of three possible answers. Most respondents, i.e. 64.71%, chose the answer "B". Over time, their flexibility has improved, but they still have problems with certain exercises. In the fifth question, they answered whether they missed the team and how they train without teammates and without a trainer. This time they had a choice of four answers. Most respondents, i.e. 41.18%, chose the answer "D". They miss their teammates and would rather train according to the trainer.

Prevention and Rehabilitation of Overloading the Connective Tissue of Lower Limbs of Ice-Hockey Goalkeepers
BEDNAŘÍK, Karel
This bachelor thesis addresses the issue of compensatory exercises as a full-value part of the training of ice-hockey goalkeepers within the scope of prevention and rehabilitation of injuries caused by a one-sided load and overloading of lower limb tissues. The first objective of the thesis was to ascertain the situation concerning the inclusion of compensatory and relaxation procedures in the training of young and adult ice-hockey goalkeepers. The second objective was to propose suitable compensatory exercises and to prove their effect on the organism. The basic strategy of the bachelor thesis was a combination of quantitative and qualitative research. When collecting the data, I used the method of structured questionnaires with open-ended and closed-ended questions, structured interviews, observation methods and special physiotherapeutic examination. I used the clinical examination methods of aspection, palpation, myodynamia measurement, goniometry and other physiotherapeutic methods. The obtained data have been summarized in tables. The tested set was created by selection when the clients had to fulfil the following requirements: - the client is an ice-hockey player at the top or high level - the client is a goalkeeper - the clients are from various age groups and various ice-hockey clubs In order to attain the first objective of the thesis, I selected a group of nine respondents from nine ice-hockey clubs associated in the Czech Ice Hockey Association (ČSLH) and foreign ice-hockey clubs. In order to attain the second objective, I selected a group of six clients which underwent a 3-month research ended with the comparison of the entry and final examinations. Based on these results, I graphically represented the effect and potential of compensatory exercises as a suitable and integral part of the training process. The results have shown that relaxation and compensatory methods are very often marginalized in the training and preparation of ice-hockey goalkeepers, although these methods may prevent one-sided overload, subsequent problems and injuries of lower limb tissues. The thesis proves that although the negative consequences of one-sided overloading are known, their compensation and remedy do not enjoy sufficient attention and no or few compensatory mechanisms are utilized in practice. Nevertheless, it is absolutely obvious from the thesis results that that compensatory and relaxation methods have a very positive effect on the problems caused by a one-sided load, both in preventive and rehabilitation terms.

School bags and problems of its weight in relation with wrong attitude in population of school children
SOUKUPOVÁ, Tereza
In my diploma thesis, I have focused on relation concerning the weight of school bags and poor posture among the population of school children. The aim of my thesis was to chart the weight of school bags at the first grade of primary school in the region of České Budějovice and Český Krumlov in relation to overloading the children?s locomotive system. A partial objective of this research was charting the content of these school bags. In my diploma thesis, I have described the locomotive system, the function of its parts and I have further analysed the development of the locomotive apparatus in each term of child?s growth organism with the emphasis on term of the younger school age. In this thesis, I have described the right posture and the most common deviations of posture from a physiological point of view. I have considered the risk factors that lead to the rise of poor posture and basic diagnostic tests, which are connected to this issue. Part of my thesis has been dedicated to the inappropriate load of younger school age children in school and the ways that this can be avoided. I have also summarised the issue of school bags. I have described how should the right kind of school bag should look like and what is required by the Czech technical norm. An additional issue I have mentioned in my thesis was the content of these school bags. In the last unit of the theoretical part of my work, I have done some research regarding the moving regimen of children in school and the ways of avoiding rising muscle imbalance. For the researching part, I have used a method of objective measuring and weighing of pupils and their school bags in each class of the first grade of those chosen schools supplemented by the information from a questionnaire given to the parents of these children. The results were processed by means of Microsoft Excel. This research has confirmed two out of four of these hypotheses; the other two were disproved. According to the data from this research, it is possible to confirm that the children were overloaded by their school bags in all classes of the first grade of primary schools, where the research was held and this fact confirms the first hypothesis. Other confirmed hypothesis was the fact that children are not allowed to keep their school supplies in their respective schools. More than half of parents answered that their children have to carry their school equipment with them every day. A positive finding was that children prepare their school bags every day with some help of their parents. Parents sometimes prepare the bags themselves or at least they check a content of the bag. This fact disproved one of the hypotheses. The last hypothesis assumed that parents don?t know about any risks connected to overloaded school bags. This hypothesis was also disproved. The parents of these children were able to state at least one of possible risks in most of cases.

Influence of Recurrent Overloading on the Integrity of Gas Pipes
Gajdoš, Lubomír ; Šperl, Martin
During hydrostatic tests of gas pipelines the tested pipeline sections are also subjected to recurrent overloading depending on the type and purpose of the test. Recurrent overloading of older piping in operation, in the walls of which the occurrence of cracks cannot be excluded, may be surrounded by some uncertainties as regards their integrity, which may be damaged. On the basis of experimental results obtained on a gas pipe with artificially generated fatigue cracks the authors analysed (from the position of the latest knowledge of fracture mechanics) the conditions that result in the bursting of the ligament in front of the crack tip during recurrent overloading, and discuss the potential mechanisms of reduced fracture pressure during recurrent overloading.
