Vondrášek, David ; Hadraba, Daniel (advisor) ; Otáhal, Jakub (referee) ; Gumulec, Jaromír (referee)
Author's title and name: Mgr. 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...

Behavioural analysis of football coaches within a training session throughout different performance levels in adult category
Hadraba, Daniel ; Buzek, Mario (advisor) ; Malý, Tomáš (referee)
5 Title: Behavioural analysis of football coaches within a training session throughout different performance levels in adult category. Annotation: The aim of this diploma thesis was to analyse the behaviour of football coaches in the male category and establish the differences in behavioural patterns of coaches between higher and lower leagues. We used coaches throughout eight different leagues and tested them with ASUOI (The Arizona State University Observation Instrument) plus an additional questionnaire. The coaches were compared according to the testing outcome and the behaviours were assessed by comparison to theoretical coaching background which has been elaborated within this paper. Keywords: Football, training session, training, coach, behaviour, ASUOI (The Arizona State University Observation Instrument).

Analysis of structural changes of nanofiber scaffolds in relation with their relative extension
Morávek, Martin ; Lopot, František (advisor) ; Hadraba, Daniel (referee)
The goal of this thesis was to find a suitable method for evaluating structural changes of scaffolds as influenced by external mechanical pressure and to verify the validity of hypothesis which assumes a change of directionality of fibers and also thinning of fibers according to the stretching of a scaffold. Assumptions formulated in these three hypothesis were tested on a scaffold with a plasma surface treatment and without any plasma surface treatment. To examine structural changes an electrone microscope was used to observe the surface of scaffolds. Incurred photos were then processed with the help of automatic software picture analysis and observed data were statisticly evaluated. The result of this experiment is a description of used method which can be used in future for larger studies. It was found that by the effect of external mechanical pressure fibers of examinated scaffolds turn in the direction of the pull. It has also been found that the average thickness of fibers didn't change. Results of this work give insight into the evaluation of structural changes of scaffolds when pressured by an external mechanical power and open possibilities for deeper and more exact research in this field. Key words: scaffold, picture analysis, fiber directionality, fiber thickness.
