Mechanical analysis of lift
Tesař, Jakub ; Kovář, Jaroslav (referee) ; Fuis, Vladimír (advisor)
The bachelor thesis deals with analysis of the system with seven solids with consideration of passive effect. In the first part of thesis describes the basics of statics and dynamics. Description of neutral and passive links, release method and reduction method. In the second part of the work are describing effects of passive effects on the movement state of the elevator. The individual bodies were released in the GeoGebra program. The aim of the example is to determine the contract forces in the links, check functionality of the links and state of motion. The solution took place in the computer program Matlab

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.

Field and laboratory testing in snowboardcross
Bohůnková, Marie ; Bunc, Václav (advisor) ; Gnad, Tomáš (referee)
Title: Terrain and laboratory testing in Snowboardcross Objectives: The main aim of this bachelor thesis is to compare the validity between terrain and laboratory tests and to evaluate the relationship of tests and the rating of the Czech National Cup in snowboardcross. Methods: Laboratory measurement of lower body measured by Bosco test (repeated jumps per 60 seconds), followed by terrain testing of lower body, which is consisted of broad jump, triple jump and shuttle run 4x10 meters. The probands are 3 female athletes in snowboardcross discipline, aged from 13 to 15 year old. The results of terrain and laboratory testing was compared with the results of rating of Czech National Cup. Results: We discovered that laboratory and terrain tests are similar. The probands has had the same position in 5 tests of 6 total. That means, that proband with the best results of terrain testing has also the best results in laboratory testing. But no proven connection between results of the test and their standing in rating of the Czech National Cup was found. The results of the best proband proved the best performance in races, but the results of remaining probands didn't confirm this relationship. The proband with the worst results of testing (laboratory and terrain) took 4th place in the rating of the Czech...

Utilization of functional exercises for strength development of lower extremities in adult football players.
Borůvka, Jakub ; Pokorný, Ladislav (advisor) ; Kainová, Lucie (referee)
TITLE: AUTHOR: Jakub Borůvka DEPARTMENT: Department of Physical Education and Sport SUPERVISOR: PaedDr. Ladislav Pokorný ABSTRACT: This researcher focuses on an overview and practical implications of functional movements that could have contributed to developing adult football players' strength skills. The aim is to establish a list of exercises based on the literature review. The research uses several research methods such as literature review, experiment and survey. The research outcome mapped a complex of activities created, especially footballers' needs. A practical program application with gained knowledge could lead to a new training approach or the change in the training purpose used by football players and travers. KEYWORDS: Condition, football, functional training, strength

Rowing machine in the sports training of rowers
Jermář, Adam ; Pokorný, Ladislav (advisor) ; Kainová, Lucie (referee)
The bachelor thesis deals with the use of a rowing machine in the sports training of rowers from the perspective of the age of rowers, when they start training on the simulator, ways and motivation of training, opinions on appropriateness, frequency and forms of training for the summer and the winter period. The characteristics of rowing, the division of rowing disciplines and categories, the specifics of fitness training and training equipment of rowers are mentioned in the theoretical part. A questionnaire survey was carried out on racing and recreational rowers in the practical part. KEYWORDS Rowing, rowing machine, sports training, motivation, winter preparation, summer preparation, physical fitness, endurance, strength

Comparison of level of motoric abilities of children in the period prepubescence with and without sports specialization
Štechmüller, David ; Kregl, Jan (advisor) ; Šťastný, Petr (referee)
Title of bachelor thesis: Comparison of level of motoric abilities of children in the period prepubescence with and without sports specialization Author: David Štechmüller Supervisior: Mgr. Jan Krégl Aim: The aim of bachelor thesis is to determine the average improvement and total performance of the testing group of ice hockey players in comparison with children from two selected primary schools in the test battery unifittest (6-60) during two testing periods. Methods: Comparison of both groups and their subsequent assessment on average. The research method of this bachelor thesis was used observing - measuring. Testig took place with children born in 2011/2012 (U6-U7). The unifittest battery (6-60) was selected to measure performances. Results: In this thesis was detected that nobody from the group of ice hockey players got to below-average values and lower in any test battery discipline. The overwhelming majority (94%) got to more than average values of testing in the final testing. By way of contrast, children from primary schools didn't achieve such an improvement and their performances had mostly average values all the time of measuring. Keywords: Unifittest, motoric abilities, speed, skilfulness, endurence, power, younger school age, prepubescence

Use of Crossfit in condition preparation in junior Ice Hockey players
Drda, Jakub ; Bunc, Václav (advisor) ; Kaplan, Aleš (referee)
Title: Use of Crossfit in junior ice hockey pre-season training Objectives: Main idea of this thesis was to prove, that Crossfit is usefull in ice hockey while pre-season. We aimed to proved crossfit improvment at generally condition presupposition, compare to other training method. Main area of condition were speed and power presupposition. Methods: In our thesis we used a method of analysis and a method of comparison. We apllied the method of analysis in pre-season of ice hockey and the method of comparison in comparing the two different types of training method. We used Crossfit as training method, which was applied on junior hockey team in second junior hockey league in Czech Republic. In the period under consideration of the performance stage we assess the change of power and speed performances of the ice hockey players. To assassmnet we used battery of test which is identify for Czech junior hockey league. Most improvement was observed in power presupposition on lower body. Results: This thesis proved that Crossfit can be used in pre-season training oj junior hockey. At the same time proved that explosive power assumption on players which used Crossfit like training method. Largest effect of progression were at explosive power presupposition. This result was in skater jumps. Keywords:...
