Risks related to open water diving and their prevention
OBORNÁ, Veronika
This bachelor's thesis focuses on the risks associated with open water diving and their prevention. Three objectives were determined to elaborate this thesis. The first objective was to find out what kind of knowledge professional and recreational divers have about the risks related to open water diving. The second objective was to examine what knowledge divers have about preventive measures related to open water diving. Last but not least, the third objective was to determine what barriers regarding the open water diving are perceived by divers. The bachelor's thesis consists of a theoretical and a practical part. The theoretical part is divided into chapters and subchapters describing the history of diving, fundamental diving equipment, basics of physics for divers and physiology related to diving. The heoretical part also describes the most common injuries and diseases occurring during diving, proper first aid as a reaction to them as well as their treatment. Finally, a part of the theory is devoted to the prevention of undesirable situations during open water diving. In the practical part of this thesis a qualitative research was applied. Data collection was conducted through semi-structured interviews. The research sample consisted of ten divers of different ages and different lengths of experience. Five informants were professional divers and five informants were recreational divers. The data obtained from the interviews were processed into four categories, which were further subdivided into subcategories. Using the qualitative research, it was found out that both professional and recreational divers have the necessary knowledge regarding the risks associated with open water diving. Despite essential knowledge and efforts to follow preventive measures, all but one informant experienced a crisis situation during a practice dive, which always turned out well due to proper theoretical preparation for these risk situations. All informants are aware that the biggest risk is the diver himself and overestimation of his own abilities. Regarding the knowledge of preventive measures related to the open water diving, there were differences between the knowledge of professional and recreational divers. All informants had the necessary awareness of the discussed topic, however it was clear that professional divers were more familiar with this issue. All informants were knowledgeable about the necessity of diving training, proper diving equipment, preventive measures and first aid procedures including cardiopulmonary resuscitation in case of an emergency situation. Moreover, it has been found out that divers perceive certain obstacles when diving in open water. In addition to poor health or psychological conditions being a barrier to diving, informants also determined low quality natural conditions as a barrier too. Deteriorated natural conditions were seen as a barrier mostly by recreational divers, whereas professional divers dive all year round and in all kinds of conditions. From the results of the research, it was ascertained that divers have sufficient knowledge of the risks associated with open water diving. Furthermore, informants have sufficient knowledge of preventive measures, which enables them to correctly assess certain situations. The fact that the informants consider the deteriorated natural conditions as a barrier to open water diving indicates that they are concerned about the prevention of risks associated with open water diving. This thesis highlights the importance of knowledge of the risks associated with open water diving and their prevention. The results of this bachelor's thesis can be used to supplement the knowledge of some divers, as a teaching material for novice divers or for health professionals who want to be aware of diving-related diseases and acute conditions related to diving itself.

Impact of gear and weaponry on posture in kneeling shooting position
Zdražila, Václav ; Vágner, Michal (advisor) ; Kubový, Petr (referee)
Title Impact of gear and weaponry on posture in kneeling shooting position Objectives The aim of this thesis is to find out the impact of gear and weaponry on posture in the kneeling shooting position. Specifically, this study examines the influence of carried load on posture, aiming stability and balance in the high and low kneeling shooting position variants. Methods This thesis has an empirical observational character. The shooting position was tested by Qualisys camera system and Kistler pressure plates. The measurment was performed on 16 Military department students with mean age of 23 years (standard deviation 2,63 years). Measurements were carried out in four levels, with no load, light load of 15 kg, mean load of 30 kg and heavy load of 45 kg. The measurement was performed on high kneeling variant and the low variant with elbow supported by the front knee. Intra-individual comparison of the results of each level was determined by a T-test. Results: The load in a form of gear and weapony had a statisicaly significant - negative influence on the kneeling shooting position posture. Gear and weaponry used for this study caused a lower trunk position, increased shoulders angle in the low variant, lesser aiming stability and balance control in the position. The bigger was the weight of gear and...

Impact of gear and weaponry on muscle activation in the direct front kick
Oláh, Vladan ; Vágner, Michal (advisor) ; Kubový, Petr (referee)
Title: The influence of equipment and arms on skeletal muscles activities while practising direct kick. Aim: The aim of this thesis was to find out the influence of carried equipment and arms on the activity of skeletal muscles when a direct front kick is being practised. The methods used: This thesis has an empirically observational character. Muscular activities were measured by means of surface electromyography synchronised by Qualisys screen system. To obtain statistic data, a t-test has been used, requiring 5 % significance level. Results: While carrying a 15-kilogram load, the activity of skeletal muscles was not significantly reduced when performing a direct front kick. However, a 30- kilogram load caused a substantial reduction of skeletal muscular activities during the kick described above. After adding a 15-kilogram bag to another 15 kilograms in the form of a body armour, a helmet and arms, the muscular activity changed its features in a considerable way. Furthermore, most respondents proved 45-kilogram load to be over their limit. The equipment and arms of that weight led to the summation action potential, exceeding the power- coordinative functional reserve, and thus the deformation of the direct front kick technique. Keywords: close combat, EMG, equipment, arms, direct front kick

The effect of material demands and socio-economic status of families on the choice of sport
Veselý, Štěpán ; Čáslavová, Eva (advisor) ; Šíma, Jan (referee)
Title: The effect of material demands and socio-economic status of families on the choice of sport Objectives: Find out if material support in the form of renting hockey gear enables families to overcome the barrier of financial demands when choosing ice hockey as a sport for children. Using the material support may be related to level of socioeconomic status. Therefore, the dependence of using material support and level of the socioeconomic status will be examined. Results can be utilised for better planning of projects which aim at supporting and expanding the membership base of ice hockey or other sports. Methods: In the thesis secondary data analysis method will be used. Moreover, primary data will be collected, using quantitative method of questioning. Results: Failure to provide material support is not a significant barrier for choosing ice hockey as a sport for children. The possibility of material support rather allows parents to easily and quickly provide their kids with hockey equipment in one place. Thanks to this, their children can try ice hockey for the first time. Possibility of renting equipment free of charge means that parents do not primarily look for a reduction of costs on purchasing of hockey gear. The socio-economic status of families whose children play ice hockey is rather...
