David Vondrášek Institution: Charles University in Prague Faculty of Physical Education and Sport José Martího 269/31 Praha 6, 162 52, Česká republika Study programme: Biomechanics Thesis name: Morphological and mechanical properties of fibrous tissue localized in congenital talipes equinovarus Thesis supervisor: Ing. Mgr. Daniel Hadraba, Ph.D. Year of defense: 2024 Number of pages: Total 111; Cover 1, Declaration 1, Acknowledgment 1, Preface 2, Table of content 2, Main text 77, Bibliography 27 Number of scientific papers: 6 papers Key words: talipes equinovarus congenitus, relapsed clubfoot, label-free optical microscopy, atomic force microscopy, mechanical properties, multi-modal analysis Text: Abstract (english) Abstract Talipes equinovarus congenitus (clubfoot) is a congenital deformity affecting lower limbs, mainly the areas around the ankle joint and foot. The affected feet have a distinct club-like appearance, where the feet are contracted to the medial side. The medial side contains fibrotic tissue, which contains an increased amount of collagen deposited by cells through fibrosis. As a result, the tissue of the medial side appears as stiff to orthopaedic practitioners, and clubfoot is frequently reported as contracted and stiff in the literature without any...

Analysis of diving locations in north-eastern Bohemia and creation of a web application
Fanderlik, Vítek ; Vondrášek, David (advisor) ; Fiala, Miloš (referee)
Title: Analysis of diving locations in north-eastern Bohemia and creation of a web application Objective: The main objective of this bachelor's thesis is to create an open web application of diving sites situated in north-eastern Bohemia, using the map software called Mapotic. Operation goal is creating a description of the areas themselves from a diver's point of view, cultural-historical or geographical-bathymetric description. Methods: Study of current and historical sources of the issue, a survey for different locations. After analysing the information of the locations, the method of summarizing key data was used to create a web application of diving areas. In order to create high-quality bathymetric maps - the consultations with map experts also took place. Results: There are clear documents of individual areas and an online open web application mapping selected diving locations in north-eastern Bohemia. Keywords: diving, diving locations, Mapotic, map software, web application, bathymetric maps

Comfort during long-term under water stays
Růžek, Jan ; Vondrášek, David (advisor) ; Fiala, Miloš (referee)
Title: The issue of long-term stays underwater Aim: The aim of the thesis is to find out how to achieve higher comfort in the experiment of staying under water surface during a long stay in a specific habitat in Slovenské Mlýn. Subsequently, from the data collected from divers who have experience with long-term stays in the habitat, to prepare suggestions for improvements that could be applied in the next experiment to achieve a higher comfort than has been the case so far. Methods: Literature and following information from the research. Informal dialogue. Conclusion: Search of professional literature and processing of achieved results from the survey. Keywords: Aquanaut, habitat, caisson, diver

Musculoskeletal problems of scuba divers
Pek, Pavel ; Vondrášek, David (advisor) ; Fiala, Miloš (referee)
Title: Musculoskeletal problems of scuba divers Objectives: The aim of this work is to determine the most common musculoskeletal problems of scuba divers. Methods: The work uses the method of research of the current state of research and quantitative research through an anonymous survey. Results: The most common musculoskeletal problems of scuba divers in the Czech Republic over the age of 18, out of a sample of 113 participants, are back pain in 43.4% (49) of respondents. Furthermore, 23% (26 respondents) report pain in the cervical spine during or after the dive, 20.4% (23 respondents) confirm temporomandibular joint pain in connection with diving and 13.3% of participants in the survey (15 respondents) report back pain in shoulder blade areas. Keywords: scuba diving, musculoskeletal system, problems, pain, disorders

Method of Diver Rescue - Audiovisual Records
Haloun, Tomáš ; Vondrášek, David (advisor) ; Bažant, Filip (referee)
Title: Method of Diver Rescue- Audiovisual Records Objective: The aim of this paper is to create a complex audiovisual record describing practical steps to help and rescue a diver underwater. Methods: As the formulation of the title implicates, for fulfilling the paper objective, themethod of recording was selected. By the means of this method an audiovisual record was obtained, which was subsequently edited and supplemented with an audio commentary. While recording methods of simulation were used.The paper is initiated by theoretical part which was completed by methods of gathering, analysis and synthesis of data and which summarizes key information important for gaining deeper understanding of the problematics. Results: Instructional video was successfully recorded. After editing the final record takes 14 minutes and 35 seconds and includes all expected parts. Key words: Scuba diving, rescuing and helping a diver, diving signals, safety, prevention

Dependence oftheair consumption and thepositionofthe body on theselectedmethodofdivingkick and swimming speed
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...

Kinesiological aspects of lower limb bilateral asymmetry
Vondrášek, David ; Hora, Martin (advisor) ; Sládek, Vladimír (referee)
Lower limbs are under the influence of relatively symmetrical loading of gait, and even so there has been evidence of bilateral asymmetry of lower limb bones in skeletal remains. The goal of this study was to search literature for possible causes of bilateral asymmetry found in dimensions of lower limb bones. This bachelor's thesis views bilateral asymmetry of lower limbs of living human from a perspective of bilateral activities, such as walking, squats and jumps and from a perspective of unilateral activities, for example kicking in football and in Taekwondo. 59 scientific articles were used in total to write this bachelor's thesis. Results of scientific articles show, that one possible cause of bilateral asymmetry of lower limb bones is preference of the lower limbs for unilateral activities. According to kinesiological articles, the unilateral kicking activity creates great mechanical loading in hip, knee and ankle joints of the kicking lower limb.
