Testing and Analysis of a Broaching Machine
Dvořák, David ; Chladil, Josef (referee) ; Sedlák, Josef (advisor)
This master's thesis deals with the broaching technology. Theoretical part includes the essay about the technology, tools and machines used for broaching. Theoretical part also describes the analysis of the broaching machine testing. Practical part is focused on the collecting, comparing and analysis of the data. These data have been collected during and after the broaching process. The supplier of the new analysed broaching machine is Stenhoj Hydraulik and the older machine has been made by Arpini. The measurements show that the increased number of broached pieces influence the cutting force and the quality of the surface due to wear of the tool which has been also monitored. The measuring dimension through the ball is almost constant. In the conclusion we evaluated the economical aspect of the results.

Modern methods in spur gearing production.
Kopečný, Libor ; Zemčík, Oskar (referee) ; Zemčík, Oskar (advisor)
The division and comparison of modern methods of production of spur gearings. The introduction is focused on the characteristics and description of cog wheels. Furthermore, the types of gearing and gear mechanisms are introduced. The main part of the text deals with individual ways of a production of spur gearings including finishing methods. The following part of this work describes the importance and possibilities of heat and chemical-heat gearing production. In the last chapters, the evaluation and achieved results of individual technologies of gearing production are introduced.

Technology of emitter production
Šrotíř, Petr ; Císařová, Michaela (referee) ; Dvořák, Milan (advisor)
The goal of this bachelor thesis is to compare the technologies of production of given workpiece using the technology of spinning and deep drawing. The object of this project is an emitter and is supposed to be made of sheet metal. The workpiece will be deep drawn in the experimental drawing tool. An economic review by production of 1000 pieces will be worked out at the end of the bachelor thesis.

Effect of strength training in improving range of movement.
Hradcová, Veronika ; Malá, Jitka (advisor) ; Šorfová, Monika (referee)
Title: Effect of strength training in improving range of movement - a systematic review Objective: The aim of this diploma thesis is to find answers to research questions in a form of systematic review and to evaluate if strength training has effects on improving range of movement, or if it restricts it or if it doesn't affect it at all. This systematic review also aims to find out how many researchers are inclined to these individual influences of strength training. Method: The Google scholar, PubMed and Web of Science databases were selected for the study search, in which 140 studies were found on basis of established criteria, which were complemented by 4 studies from other sources, from which 128 were subsequently obtained after removing duplicates. An abstract of these studies was studied, of which 95 studies were unsuitable and were therefore excluded. The remaining 33 studies were further studied and, if they met the criteria of at least one research question, were subseqently included in present review. A total of 18 studies were included in present review, which were further classified into research questions according to additional criteria. For each research question, the studies were evaluated separately and the results of the studies were clearly recorded in a table for subseqent...

Evaluation of the short-term effect of physiotherapeutic techniques on spasticity in patients with spinal cord injury
Špačková, Anežka ; Hlinková, Zuzana (advisor) ; Kříž, Jiří (referee)
The subject of this thesis is spasticity in individuals with spinal lesions. The aim is to evaluate and compare a short-term effect of selected physio-therapeutic methods on spasticity of lower limbs in spinal patients. Two methods of comparison were chosen - passive stretching and the Vojta's reflex therapy. The work consists of two parts. The theoretical part describes the problems of spinal lesions, central motoneuron syndrome and spasticity, including its pathophysiology and investigation and therapeutic approaches. The practical part contains an attempt to verify and subsequently compare the immediate antispastic effect of the chosen methods, which is an important prerequisite for the following active exercises as an inseparable part of a physiotherapeutic exercise unit. Clinical evaluation scales are used to evaluate spasticity, namely Modified Ashworth Scale (MAS) and Muscle Excitability Scale (MES). The results are then compared with other studies and literature. Keywords spinal lesions, quadriplegia, Modified Ashworth Scale, Muscle Excitability Scale, Vojta's method, stretching

Stretching and the Maximal Muscle Strength
Šádek, Petr ; Konopková, Renata (advisor) ; Otáhal, Jakub (referee)
Title: The effect of stretching on maximal muscle performance Objectives: Due to the number of studies, concerning the effect of the muscle stretch on sport performance and their heterogeneity in the term of used parameters, tests and even performing the stretch exercises themselves, it would be desirable, thanks to the importance of this subject, to consolide and evaluate up-to-date knowledge. The goal of this diploma thesis is to compare and assess available literature concerning the effect of muscle stretch during warmup on the sport performance and, ideally, to define the best type of the stretching itself. Method: The diploma thesis is composed as a literature review - an integrative review with exactly defined criteria for the use of available studies. Result : Even with the nonuniformity of parameters used in available studies there is a consensus in most of the used sources, which met the criteria of inclusion in this research, which (the consensus) determinates the dynamic stretching as the form most appropriate for enhancing the following sport performance. Although studies, proving this result, are in their findings quite unanimous, a precise definition of prefered exercises for peforming the dynamic stretching and of its parameters is still missing. Key words: stretching, dynamic,...
