Development of core muscles
Uchytil, Lukáš ; Jebavý, Radim (advisor) ; Blažek, Dušan (referee)
Title: Development of core muscles Objectives: The aim of the practical part will be the creation of a test battery for trunk diagnostics and its pilot validation in active athletes. Methods: The research was conducted as a pilot study, with a random sample of participants aged 22-23 years. The following exercises will be included in the tests: prone plank, strict toes to bar and sit-ups. The data from the testing was evaluated using the statistical functions mean, standard deviation. Results: The results showed that all the participants achieved an excellent result in the prone plank test, bellow-average result in the strict toes to bar test, and one participant achieved an excellent, one good, and one average result in the sit-up test. Keywords: core, strenght, deep core muscles

Strength and conditioning training in sprint canoeing
Zalubil, Jiří ; Bačáková, Radka (advisor) ; Brtník, Tomáš (referee)
Title: Strength and conditioning training in sprint canoeing Purposes: Creating an overview of the periodization of fitness training in sprint canoeing. Focus on the development of individual fitness components and characterization of athletic performance. Methods: A review study without research activity. It is a qualitative review of information from which conclusions are drawn without any quantitative manipulation or analysis. Results: Strength and conditioning training is an inseparable component of sport performance in sprint canoeing. In preparation, emphasis should be placed on the development of strength and endurance skills. However, it is necessary to follow the correct procedure and dosage of individual training means to maximize sports performance and achieve a high level of training. Conclusions: Sprint canoeing places high demands on fitness training. Athletes with a high level of strength and endurance skills are especially suitable. Key words: Sprint canoeing, strength, endurance, speed, conditioning components, periodization

A popular fairy tale as a theme referring to the sources and strength of it's author
FEJTKOVÁ, Tereza
The work deals with the search for the strength and resources of man in his favourite fairy tale story. The theoretical part deals with the fairy tale in general, its characteristics and structure. It also summarizes the importance of the psychological effect of the fairy tale on man. The application of fairy tale themes in art therapy work is described in more detail, and the background of projective-intervention therapy is mentioned.The practical part focuses on the search for strength and resources in the theme of My Favourite Fairy Tale. Seven case studies are presented, which are developed using a qualitative research method. In line with the focus of the art therapy study, the respondents' artifacts are interpreted in detail. The findings from the practical part of the thesis, together with the theoretical aspects, are compared in the discussion and the results are summarised in the conclusion of the thesis.

Stress-strain analysis of a crane arm
Mora, Lukáš ; Halabuk, Dávid (referee) ; Fuis, Vladimír (advisor)
The content of this bachelor’s work is a summarization of types of tower cranes and subsequent stress-strain analysis of the crane arm of the crane type 150EC-B8 Litronic located on the Šumavská street in Brno. Analytical stress-strain analysis is calculated with equations of equilibrium using joint method in various types of loading of the construction with MAPLE software. Numerical calculation is executed on 3D model of the construction in software ANSYS. The aim of this bachelor work is the verification of the correctness and comparison results of analytic calculation with numeric calculation and evaluation of the results from a limit states and deformation standpoint.

Analysis of specific systems of bodies with neutral bonds
Grúz, Jan ; Hájek, Petr (referee) ; Majer, Zdeněk (advisor)
This thesis deals with analytical and graphical solution of three specific systems of bodies that are in static equilibrium. These systems of bodies contain neutral bonds. The opening part dedicates to theory and principles of solution of contact forces in bonds, which are further used for calculations and graphical solutions. The first system of bodies is a demonstrative tappet mechanism which was created for demonstration of some methods of graphical solution. The second system is inspired by lifting mechanisms in production lines. The aim is to find out the magnitude of contact forces for different positions of the lifted weight and a minimal torque of the propulsion. For solving the third system of bodies, principles of statics and hydrostatics are used. The aim is to find out the minimal magnitude of force for activating the mechanism. All systems of equations are solved in Matlab.

Calculation of electrodynamic forces in 250 A circuit breaker
Görig, Michal ; Dohnal, Petr (referee) ; Valenta, Jiří (advisor)
This master’s thesis deals with the calculation of electrodynamic forces breaker BD250NE305. Main tasks in this semester project is to study the theoretical analysis of individual parts specified breakers. Processing theoretical analysis of these forces. Creating a 3D model current path and sheets quenching chamber single phase circuit breaker in Autodesk Inventor Professional 2012. Another challenge is the subsequent export the model into the simulation program ANSYS Maxwell. After simulation, the specified conditions must be processed and the results of the present work is to evaluate.

Mechanical analysis of the subsystem of the tower crane
Urbánek, Roman ; Venský, Jiří (referee) ; Fuis, Vladimír (advisor)
The bachelor thesis deals with the solution of a subsystem of a tower crane with a passive effect (NNTP). First part describes tower cranes and their parts. The following part is a description of the theoretical and physical laws of statics and dynamics. In the practical part, various states of motion of a specific modeled subsystem are calculated, which shows a trolley of the tower crane. The aim of the calculation of each configuration is to determine the numerical values of the contact forces in the links, to analyze the dynamic quantities and to evaluate the functionality of the links. Numerical values of unknown parameters were calculated by solving a system of linear equations in the calculation software Matlab.
