The explosive power of the lower limbs in handball.
Frkal, Jakub ; Tůma, Martin (advisor) ; Šťastný, Petr (referee)
Název: Odrazová síla dolních končetin v házené Cíl práce: Vytvořit program pro zlepšení odrazové síly dolních končetin u vybraného družstva starších dorostenců v házené. Metody: U experimentální a kontrolní skupiny jsme použili klasické testování na základě náhodného výběru. Dále jsem v průběhu experimentu využil tři metody rozvoje odrazové síly dolních končetin: kontrastní, rychlostní, plyometrická. Dále byla využita statistická metoda pro komparaci výsledků. Výsledky: Výsledkem práce je zjištění, že u sledovaného družstva byl vytvořený program rozvoje explozivní síly účinný. Probandi z experimentální skupiny dosáhli za sledované období výrazného zlepšení ve většině cviků testové baterie. Klíčová slova: Házená, odraz, silové, koordinační schopnosti, explozivní síla. ABSTRACT Title: The explosive power of the lower limbs in handball. Objectives: To create a program to improve explosive power of lower limbs of the cooperative older juniors handball. Methods: In experimental and control groups, we used the classical testing on a random basis. I also used three method during the experiment to develop explosive power of the lower limbs: contrast, speed, plyometric. It was also used statistical method for comparing results. Results: The finding is that in the reporting team was created explosive...

Dependence of performance in selected athletic disciplines students in second level primary schools
Vopršálek, Radek ; Kašpar, Ladislav (advisor) ; Svobodová, Irena (referee)
NAME: Determine the dependence of performance in selected athletic disciplines students in primary schools AUTHOR: Radek Vopršálek DEPARTMENT: Katedra tělesné výchovy SUPERVISOR: PhDr. PaedDr. Ladislav Kašpar, Ph.D. ABSTRACT: The aim of this thesis is to explore the relationship and dependency between performances in chosen sports disciplines for pupils of primary school. The disciplines I have chosen to determine the relative performance are: long jump and 60 meters sprint. In the theoretical part there is a description and analysis of these sports disciplines. In the practical part there is a measurement of pupils' performances in that two sports disciplines and creating a dependency relationship between them. KEYWORDS: Long jump, Bounce, Run, Relationship.

Myodynamics of the support phase during different take-off tasks in human locomotion
Hojka, Vladimír ; Jelen, Karel (advisor) ; Otáhal, Jakub (referee) ; Kampmiller, Tomáš (referee)
Title: Myodynamics of the support phase during different take-off tasks in human locomotion Objectives: Six types of take-off movement were analyzed in terms of support limb kinematics, take-off dynamics and muscle activation, in order to identify differences in motor control. Methods: 14 male athletes (22.6 ± 4.4 years; 182.4 ± 5.3 cm; 74.7 ± 6.2 kg) took part in laboratory experiment. Each athlete performed six different take-off movements (running, acceleration - first and second step, long jump take-off, high jump take-off and take-off to the hurdle). System Qualisys was used to analyze kinematics of the support limb. Dynamic of the suport phase was measured with Kistler 9281 EA force- plate. ME6000 apparatus was used to measure the muscle activation. Results were processed and statistically evaluated in Matlab (MathWorks, Inc) environment. Pair ANOVA, T-test and Friedmann test were performed to identify differences between take-off movements. regression analysis was introduced to find the relationship between parameters. Results: Significant differences in take-off dynamics are realized with not so significant differences in kinematic and electromyographic parameters. high jump and long jump take-offs acted most specifically in comparison with other types of take-offs. Two typically...

Looking Back
Ivanová, Karolína ; Hládeková, Katarína (referee) ; Smetana, Matěj (advisor)
In my bachelor thesis I will deal with the connection between observation and photography process. I watch how the process of photography is born in its simplest and most basic form and in the initial idea. The first part of my bachelor thesis consists of audio recordings where I capture the everyday moments of interest that I was interested in. I am interested in the relationship between photos by word / language, how the language enters the photo, and vice versa. It is enough to look at the picture and associations and memories and ideas are reflected in words and images. It's about raising "mental" photos in my mind. The second part of my bachelor's thesis consists of a mirror object, which is activated only when the viewer is involved in the observation process.

Processing and analysis of HS videorecords of liquid atomization for a pressure-swirl nozzle
Červenec, Adam ; Lízal, František (referee) ; Jedelský, Jan (advisor)
This bachelor thesis deals with processes of liquid atomization for a pressure-swirl nozzle. The main goal was to study liquid cone, which is gradually fragmenting on smaller parts ending in creating small droplets. It was needed to study theory of liquid flow, motion of droplets and an impact of the geometry of nozzle. When the theoretical part ended we could perform an experiment, which consists of preparing devices and creating own video records using highspeed camera Photron FASTCAM SA-Z. The camera provided us detailed view on the spray and events, for example collisions of droplets, which are the main subject of this thesis. Afterwards the video records were analyzed and we could provide results connected with studied problem.

Rendering of Terrain and Water Surface in a Computer Game
Kopecký, Marek ; Kajan, Rudolf (referee) ; Herout, Adam (advisor)
This bachelor's thesis deals with rendering of water and terrain, which is a key part of many computer games and simulations. The resulting application runs fluently and is powered by XNA Framework. Rendering of terrain includes multi-texturing and lighting. The water simulation includes reflection and refraction of ray on water surface. Foam is rendered on the bank of water. Water waves are computed using the inverse discrete Fourier transform.

Graphics Intro 64kB Using Ray Tracing
Krupa, Martin ; Navrátil, Jan (referee) ; Herout, Adam (advisor)
The object of my bachelor's thesis was to get acquainted with phenomenon of graphics intro with limmited size, to study actual display techniques, which are using real-time ray tracing and make own graphics intro by using these techniques and executable of this intro is limmited to 64kB. The work also briefly introduces history of making graphics intros and reasons for their creation. It contains description of techniques used to create intro and comparation of them. This work also describes own implementation of aplication and its results. Finally there is evaluation of thesis and ways of improvements.

Optoelectronic sensor of polarization state of light from biological samples
Mikláš, Jan ; Brüstlová, Jitka (referee) ; Tománek, Pavel (advisor)
The living body tissues consist of cells which dimensions are bigger than a wavelength of visible light. Therefore a Mie scattering of reflected of backscaterred light occurs and different polarization states arise. The changes of polarization state due to the multiple scattering of light in the biological cellular tissues allow measure the aging of biological tissue. The reflected or backscattered polarized laser light exhibits multiple scattering on the sample surface and in its subsurface area.
