Differences in inhalation between men and famales during the identic scuba diving output
Rosenkranzová, Michaela ; Bažant, Filip (advisor) ; Vondrášek, David (referee)
Name: : The difference of consumption of a medium being inhaled between a man and a woman at the same level of endurance in scuba diving. Goals: The primary goal of this work, is to determine if and how is the amount of the inhaled medium depending on the gender of the divers. Compare the consumption between men and women while being faced with the same amount of stress, meaning during a united profile of a dive, try to maximize the decrease of the influence of stress factors. Confirm or deny the hypothesis that men show higher values of the inhaled medium. Methods: The theoretical part of this paper, was created based on the research of the appropriate literature. To obtain all the data, there was used the method of experiments, the results were then analyzed, compared and than statistically evaluated using the Students T- test. Probandi (n=10+10) took part in a 30 minute long and 20 meters deep dive in Bořená hora, during which their consumption of the inhaled medium was recorded every 5 seconds using a special underwater computer with a probe. Results: It was found out that men, during the same dive, consume more air than women because of their higher body weight. Key words: scuba diving, air, sex, respirator, minute ventilation

Physiological differences and potential risks while scuba diving and freediving
Flodr, Tomáš ; Fiala, Miloš (advisor) ; Hošek, Václav (referee)
Title: Physiological differences and potential risks while scuba diving and freediving Objectives: Goal of this study was to prove, whether freedive performed after finished dive using self-contained underwater breathing apparatus, may potentially increase the risk of decompression sickness and afterall put together appropriate principals and guidance for safe combining of both scuba diving and freediving on the same day. Methods: This study used research of local and foreign sources that covered freediving and diving using self-contained underwater breathing apparatus issues. Casual research was also conducted involving 34 participants, all certified self-contained underwater breathing apparatus divers experienced in combining freediving and scuba diving on the same day. Results: Based on the research has been found that a freedive performed after dive using self-contained underwater breathing apparatus may under certain circumstances increase the risk of decompression sickness. Conservative principals and recommendations for safe combining of scuba diving and freediving on the same day were established. Results of this study will be provided to local and foreign diving communities. Keywords: Scuba diving, decompression sickness, nitogen load, freediving, risks

Ehl, Sebastian ; Vondrášek, David (advisor) ; Bačáková, Radka (referee)
Title: Dependence of the air consumption and the position of the body on the selected method of diving kick and swimming speed Objectives: The goal of this work is to find out the relationship between the diver's swimming speed and the air consumption while using two different methods of diving kicks - flutter and frog kick. At the same time, assess the dependence of the position of the body and head on the swimming speed and method of diving kicks. Methods: In this work was used method of collecting data in real conditions by measuring devices and statistical evaluation of collected data. Results: The results are presented by graphs both in the text of this work and in attachment for its large size. The results of all probands are presented in summary graphs and for selected values the degree of association is calculated in tables using the Pearson correlation coefficient. The main result is the confirmation of the reduction of the deviation from the horizontal position when comparing the slow and higher swimming speeds of both flutter and frog kick. The most effective way for a diver to overcome 50 meters below the water surface was determined to be a flutter kick at medium speed (average 0,37 m/s). Keywords: scuba diving, body position, head position, air consumption, speed of swimming, flutter...

Use of physiotherapy for vertebrogenic difficulties associated with scuba diving
DVOŘÁKOVÁ, Kamila
This work is about using physiotherapy methods in patients with vertebrogenic difficulties associated with scuba diving. The first goal is to suggest therapy for concrete patients with vertebrogenic difficulties and the second goal is to chart the effects of the therapy performed in concrete patients with vertebrogenic difficulties. The work is divided into two parts, theoretical and practical. The theoretical part describes the issue of vertebrogenic difficulties, describes the anatomy and kinesiology of the spine, presents scuba diving and presents the possibilities of using physiotherapy. The practical part consists of four case reports and a description of the proposed therapy. The work is processed in the form of qualitative research. Data collection was performed by the entry and exit examination. The results were based on qualitative analysis of these data. The research group consisted of four probands who spent their free time on scuba diving while suffering from occasional vertebrogenic difficulties. The research took the form of regular meetings, usually held once a week for two months. Therapy results are ambiguous. There were both objective and subjective improvements in two probands. One of the probands did not match the subjective impression with objective results and one of the probands has worsened. Many factors could have affected the results. For example, by an individual approach to therapy, by other sporting activities performed in addition to exercise, or by injuries made during therapy. The theoretical part can be used as a source of information for divers as it highlights the risks of developing vertebrogenic difficulties. The practical part can be beneficial in physiotherapy practice as an exercise unit not only for divers.
