Risks associated with diving and their prevention
DIVIŠOVÁ, Anna
The topic of this bachelor thesis is called: "Risks related to diving and their prevention." The theoretical part is mainly focused on health risks which arise during scuba diving and follow-up prevention of the health risks. Furthermore, the following topics are mentioned in the theoretical part: a history of diving, biophysical concepts, and necessary equipment. Because of this topic, it was important to include chapters about first aid, treatment and medical fitness for diving. A reduction of health risks was chosen as the main objective in the practical part. There were 5 research questions created. 1. What is the training of divers? 2. What is suitable equipment for diving? 3. What conditions are convenient for diving? 4. What is currently the prevention of health damage during diving? 5. How can we reduce the risk of health damage? The qualitative research measurements were used for the creation of the research part of this bachelor thesis. A semi-structured interview containing 15 questions was created to get the data. There were 15 divers chosen for the interviews, 5 professional divers and 5 hobby divers. According to the results, it was found that there is a fundamental difference in the knowledge of the divers about this topic. Very often the risks are caused by insufficient preparedness and knowledge of the diver, not handling of the panic and stress, and a wrong reaction. Disobeying of precautions and principles often contributes to that. The results of this bachelor thesis may be helpful in completing education and information of divers, but also medical staff.

Analysis of fatal accidents in the Czech Republic during scuba diving from 1997 to present
Kleinová, Karolína ; Vondrášek, David (advisor) ; Dvorský, Jaroslav (referee)
Title: Analysis of fatal accidents in the Czech Republic during scuba diving from 1997 to present Objectives: The aim of the thesis is to collect and analyze information about fatal accidents in scuba diving, which took place since 1997 to the present on the territory of the Czech Republic, to highlight their possible causes and common denominators. Another aim is to point out causal connection of factors leading to the deaths of divers through case studies of a few selected accidents. Methods: To meet the objectives of the work was used both quantitative and qualitative approach. In the quantitative part of the work were used data collections and analysis of information about the investigated accidents. In the next part of the thesis were used qualitative analysis of selected expert opinions received from expert in the field of diving. Results: The most frequent disabling injury in observed cases is a barotrauma and the most frequent cause of death is a suffocation caused by drowning . An important discovery is frequent neglecting of safety policy and overrating self capability in connection with the level of competence and experience. Keywords: diving, fatal accidents, risk factors

Drafting a methodology plan for training springboard diving of school children
KOČAŘOVÁ, Jana
As the theme of my bachelor thesis I chose a draft of the methodical plan of diving for school children with respect to primary school children. The theoretical part defines the term "diving" as a sports discipline with an accent to all-round physical development. I focused to the individual age period in various parts of the training technology in diving. The thesis describes the activity of diving group, shows the sports training in general level and also in leisure perspective. The focus of the work is to propose the creation of a methodical plan and the training objectives. Training goals are achieved by defined jumps. All above mentioned areas are partitioned into several sections. In practical terms, this thesis is applicable for coaches of primary school children which are starting with the diving.

Effect of hyperbaric environment on fine motor skills
Les, Martin ; Vondrášek, David (advisor) ; Dvorský, Jaroslav (referee)
Title: Effect of hyperbaric environment on fine motor skills Objectives: The aim of study is to assess the changes fine motor skills due to hyperbaric environment in preparation for selected tests of fine motor skills. Methods: The first method was used empirically - research. Then the method chosen of compilation of the information obtained. The basic method to work was the experimental measurement method specially constructed tests on fine motor skills. All measured values were statistically processed as follows. Results: The results were formulated as a percentage, graphs and tables. Recording was carried out by recording the time data. Their percentage of the overall approach to the exercise time mastering fine motor skills in different environments. All results obtained were processed and evaluated. Keywords: depth intoxication, fine motor skills, hyperbaric environment, hyperbaric chambers, diving

Influence of temperature on the diving reflex
Soustružník, Ondřej ; Vondrášek, David (advisor) ; Bažant, Filip (referee)
Title: Influence of temperature on the diving reflex Background: It is likely that the sum of the defense systems of the organism to changes in temperature known as the diving reflex occurs in each individual differently depending on the physical preparedness. Objectives: Check the effect of temperature on performance-diving reflex two different groups - experienced and novice divers. On the basis of experimental testing in hot and cold water, check the reaction of the body to different environmental conditions. Based on the physiological changes in an organism to assess whether it was demonstrated physiological ability of the body, known as the diving reflex. Methods: Experimental testing beginner diver (n = 5) experienced divers (n = 5) in hot water of temperature 20 - 25 ř C and cold water at a temperature of 4-6 ř C in the static apnea. Based on the measured values, changes in the body, heart rate, oxygen saturation, the overriding influence of sympathetic and parasympathetic, concentration and relaxation index to assess the extent of reaction of the organism and the subsequent involvement of the defense systems of the organism, as called diving reflex. To assess the difference between groups were used statistical methods - Cohen da Kolmogorov-Smirnův test. Results: The results of experiments...

Title: Use of gymnastic training in diving Objectives: The main purpose of this thesis is to describe opinions of diving coaches on use of acrobatic training and gymnastic equipment to train divers of different ages. Methods: The analysis of related literature, survey and selected methods of descriptive statistics and data analysis. Results: From the results of this thesis is obvious, that diving coaches consider use of gymnastic training as very beneficial in terms of cultivation of divers performance in relation to influence the performance and also as necessary part of their preparation.

Analysis of the motion and position on the movement of the human body during scuba diving
Ehl, Sebastian ; Vondrášek, David (advisor) ; Bažant, Filip (referee)
Title: Analysis of the motion and position on the movement of the human body during scuba diving. Objectives: The goal of this work is to find out which movements our body, as a complex mechanism, does during diving with diving equipment. The statistics was made with five probands in the set of six measurements. This statics supposed to show us what effect does speed of swimming on body possition when the flutter kick or frog kick is used. The move in frontal and vertical axis of the swimmer will be evaluated in both style of swimming, also the observational error will be evaluated. The goal of this work is not to messure exact angles but how those angles changes according to speed of swimming. Last but not least will be determined the conection between speed of swimming and body position. Methods: For this work was used method of collecting data in real conditions by measuring device and statistical evaluation of collected data. Results: Results are presented by graphs where are the measured data of all probands. These data are compared with each other and added to another graphs. In tables there are correlation coefficient for link between size of angel and velocity of swimming under water surface. It was found that with high association the size of angle between the axis of the body and the...
