Analysis of soccer match loading according to player position.
Bujnovský, David ; Malý, Tomáš (advisor) ; Buzek, Mario (referee)
Title: Analysis of load football players in a match in terms of gaming post. Objectives: The aim of this essay is to determine the size of the musculoskeletal load of players during friendly football matches. At the same time the aim is to determine the differences in the size of the musculoskeletal load between the different players' positions measured in the file. Methods: This essay deals with the indirect (mediated) observations, due to the fact that data was recorded by devices from which this data was then processed to obtain the result. To evaluate the size of the musculoskeletal load sport testers "Polar Team 2" were used. For the statistical evaluation the processed material significance using the so-called "size effect" was used. Results: Regarding the size of the musculoskeletal load, no substantively significant difference was found between the defenders and midfielders in the zone above the ANP. Significant material differences were observed between defenders and attackers, materially significant differences were also found between the midfielders and attackers in the zone above the ANP. However, based on the conditions under which measurements were carried out, it is clear that definite conclusions cannot be drawn. Keywords: Football, physical load, heart rate, player's positions

Sacherová, Jana ; Panská, Šárka (advisor) ; Lopot, František (referee)
Title: Human axial system: identification of connective tissues changes Objectives: The main objective of this thesis was to compile a review of techniques and methods currently used in identification of connective tissues changes. Methods: The method used in this thesis is a critical literature review - a study of research papers from available information sources accompanied by author's comments. Foreign sources are represented mostly by research papers accessible via electronic archives such as ScienceDirect, Pubmed, Springer, Wiley. Also other foreign publications were used. The theoretical part is focused on basic anatomy and physiology of the spine and states main methods of identification of connective tissues changes involved in this area. The main part describes particulars of researches dedicated to identification of functional and morphological characteristics of different spinal components. Results: In addition to classic methods of spinal research, the thesis introduces also new developing techniques and methods. Procedures used in current research are described; their advantages and limits are explained. Key words: spine, biomechanics, loading, intervertebral disc, method

Sexual dimorphism in tibial loading during human locomotion
Dvořáková, Barbora ; Hora, Martin (advisor) ; Friedl, Lukáš (referee)
Locomotion is one of the most important qualities of man and has always been associated with survival, foraging ans subsistence. During the course of evolution, men and women developed some form of gender specialization which resulted in different level of mobility between the sexes. Throughout history, the types of subsistence have changed and the degree of sedentism has increased. However, despite all the changes in subsistence, gender specialization and bone robusticity sexual dimorphism in the robusticity of the lower limb bones remained surprisingly stable. Is it possible that women load lower limb bones differenty than men (e.i. due to different body proportions)? The aim of this work is to determine wheter there is sexual dimorphism between the sexes of the recent living population in the cross-sectional properties of the tibia and in the load on the tibia during running. In this work we used images of the tibia from magnetic resonance imaging and kinematic and kinetic data during the run of 20 probands. By using musculoskeletal modeling we estimated the bending moment acting at 50 % of the tibial length as well as the angle of action of this moment. After adjusting for size, no significant difference was found in the results of cross-sectional geometry of the bone in any of the monitored...

Time-motion analysis of elite Czech sport climbers during Czech Lead Climbing Cup
Ježková, Ludmila ; Baláš, Jiří (advisor) ; Kodejška, Jan (referee)
Title: A time motion analysis of lead climbing of elite climbers in the competition route of Czech Cup. Objectives: The aim of this works is to perform time motion analysis of lead climbing of elite climbers in the competition route of Czech Cup. Methods: Data were collected by video recording. Observation criteria were set (total time, holding, quickdraw clipping, rest and chalking). 8 climbers were measured on the 10- UIAA difficulty route. Results: The average climbing time was 203 ± 32,6 s, the average holding time was 7,1 ± 0,8 s (total 161,3 ± 29,2 s), the average rets period was 1,2 ± 0,4 s (total 6,5 ± 3,3 s), the average quickdraw clipping time was 2,3 ± 0,4 s (total 24,9 ± 4,6 s), the average chalking time was 2,1 ± 0,6 s (total 16 ± 3,7 s) and the average hand-transfer time was 0,9 ± 0,2 s (total 38,4 ± 9,1 s). Climbers climbed 4,8 meters per minute. Conclusions: The static part almost four times prevails the dynamic part. There were no significant differences between right and left hand in our measurements. Keywords: holding, loading, rest, static phase, dynamic phase

Diagnosis of Pneumatic Cylinders Using Acoustic Emission Methods
Mahmoud, Houssam ; Baran,, Ireneusz (referee) ; Santos, Serge Dos (referee) ; Mazal, Pavel (advisor)
Tato práce se zabývá vývojem nového efektivního diagnostického postupu pro kontrolu funkce pneumatických válců pomocí metody akustické emise. Cílem práce bylo navrhnout a určit diagnostická kritéria pro hodnocení kvality vybraných typů pneumatických válců. Prvním krokem bylo nalezení typického akustického emisního signálu, který je spojen s určitým typem poškození ve válci využitím frekvenčního spektra signálu. Později byl tento parametr nahrazen parametrem RMS během sledování změn v průběhu testů. Na konkrétních válcích byl sledován vztah mezi akustickou emisí a různými typy defektů a byl představen nový přístup k určování těchto typů vad a jejich odlišením v signálu akustické emise. Druhý krok studie že neporušené a poškozené válce byly porovnávány tak, aby se zjistily výrazné rozdíly, které určují, zda je válec poškozen nebo nepoškozen. Několik nepoškozených válců bylo testováno akustickou emisí a následně v nich byly vytvořeny umělé vady. Signály z vysouvání a zasouvání pístu byly zaznamenány a analyzovány pomocí řady parametrů. Na základě časového zpoždění a normalizace RMS byly rozpoznány odezvy mezi poškozenými a nepoškozenými pneumatickými válci. Rozdíly byly zjištěny porovnáním maximální hodnoty RMS ze snímače upevněného na předním víku válce a snímače upevněného na zadním víku válce pro jeden cyklus. Poškozené a nepoškozené válce byly rozlišeny pomocí rozdílů energetických hodnot přítomných v signálech z obou snímačů v závislosti na zdvihu pístu. Konečné vyhodnocení válce bylo určeno výpočtem celkové hodnoty RMS. Ve třetím kroku experimentu byly válce postupně zatěžovány různými závažími ve svislém směru. Signály akustické emise byly zaznamenány z vysouvání a zasouvání pístu a poté analyzovány. Časové zpoždění se vypočítává z digitálního vstupu a začátku pohybu pístu. Energie signálu a RMS akustické emise porovnávají různé reakce v poškozených a nepoškozených pneumatických válcích s a bez zatížení. Výsledky testu ukázaly lineární vztah mezi křivkou RMS a zatížením. Defekty ovlivňují vztah mezi aplikovaným zatížením a zaznamenaným signálem snímačů.

Design of steel-concrete arch structure of footbridge over the river Svratka
Vraňanová, Veronika ; Marván, David (referee) ; Nečesal, Petr (advisor)
The main goal of this diploma thesis was to project a design of arch bridge‘s framework over the Svratka river. This single-span bridge has the span of 52,5m. The framework is constructed from a pair of beams, suspended from the pair of beams bent towards each other. The bridge deck is coupled with steel crosspieces. The construction design was executed in computing programme Dlubal RFEM 5.07. The individual components of the framework were assessed in Microsoft Excel. The calculation considered the load of wind and pedestrians’ movement and their effect on the dynamics of the construction. The phases of development were also considered. Assessments of coupled cross-section, main beams of steel construction, tension systems and selected construction joints were executed in a static calculation. Moreover, a design of a bearing and a bridge plug joint. Finally, a drawing documentation and a final report were prepared in regards with the requirements. The construction design and its assessment were executed according to valid standards.
