Title: The influence of two different lower limb exercises on the speed of skating during dry land training in young ice hockey players aged 17 to 20. Aim: The aim of this study was comparation of the effect of two variations in preseason pre preparation on speed of skating. Methods: The hockey players in the age from 17 to 20, who have been training ice hockey for 12 - 14 years, have been watched. The hockey players have been divided into two groups on the base of the technology of the skating. The speed of the skating, have been measured at all hockey players at the beginning of the watching. Then the hockey players have absolved the summer preparation. The capacity of the training has been the same for both groups (the amount of the lessons, frequency, etc.). The difference was in the way of performing of some exercises, mainly the exercising of the legs. The first group has been doing the exercises in the "speed" form, while the second group has been doing the exercises in the " strength" form. The effect of the used training has been controlled by the motoric tests. The speed of the ice skating has been evaluated again before the beginning of the playing season. The results have been statistically elaborated and compared. The results: Both training systems have significantly improved...

My thesis deals with the status of German language standard and is based on research in the internet discussion sites (internet forums), that deal with the topic of language. The internet forums that I've chosen offer help in learning a foreign language, in our case German. The help is provided either by proofreading or by answering the specific questions. This thesis is based on Ulrich Ammon's model of four social forces and the theory of language management. Next to the instances, which according to Ammon determine the standard, I included the participants of discussion, who decide what is standard too and thereby affect those for whom isn't German the native language. The analysis will be carried out on the basis of the proofreading of model texts. With the help of the language management theory I will discuss with the proofreader in the comments their selected (or not selected) option. The aim of my work is to observe the behavior of normative authority in relation to the codified norm, whether they know and follow it. Furthermore, I am interested in the social background and language abilities of the participants, which I'll find out by using the questionnaires.

Title: The relevance of Bosco test for determination of healthy oriented efficiency adolescents Objective: The main objective is to find and describe the relationship of Bosco test (60 s) to a specific level of health-related fitness among adolescents based on the comparison of the output parameter of Bosco test and test items EUROFIT at physically active and inactive boys and girls. The partial objectives are to describe the influence of anthropometric parameters, gender and competence to physically active people on the current level of power parameters of the lower limbs. Methods: The dissertation has the character of empirical research, it is a descriptive study in which the research has a nature of the association, ie., that the required data are obtained by observation. The study was carried out on a group of purposefully selected probands n=100 age 18.40 ± 0.83 years, a period of adolescence. In the study group was equal representation of boys n=50 (age 18.50 ± 0.84 years) and girls n=50 (age 18.38 ± 0.82 years). Anaerobic capacity and power parameters of the lower extremities were determined by a standardized jumping Bosco test (60 s). The results of laboratory and anthropometric survey results were referenced by a test battery EUROFIT, which provides information on health-related fitness....

Subject of the thesis is study of photon strength functions describing the gamma decay of the nucleus. During last 50 years a number of theoretical models for these quantities were proposed, however, their accuracy is still de- batable and its verification has recently been a subject of intensive experimental and theoretical research. In this work measurement of multi-step gamma cas- cades following the radiative neutron capture on target nucleus 167 Er is used to analyse photon strength functions. The experiment was performed with DANCE calorimeter located in Los Alamos Neutron Scattering Center. The experimen- tal spectra are compared with Monte Carlo simulations of electromagnetic decay using the DICEBOX algorithm, based on assumptions of Extreme Statistical Model. Comparison of experimental and simulated spectra is a fundamental tool for studying correctness of theoretical models of photon strength functions. This study provides information mainly about E1 and M1 photon strength functions, especially properties of the so-called scissor mode are analysed.

Title: Optimization of warm-up before speed-strenght loading Objectives: The aim of this work is to compare three variants of warming up and to determine the most appropriate one before speed-strenght loading. Methods: The test group consisted of 15 male students of the Faculty of Physical Education and Sport at The Charles University at the age of 22 -26 years. The tested subjects underwent 4 tests within 4 weeks. The first test was used to determine the 1 RM bench press and leg-press, the results of which we needed for the proper determination of the weights for the following protocols. The other three measurement protocols include three warm-up (base, a speed-strenght and toning), followed by a test of explosive strength in arms and legs. Countermovement vertical jump height with arm swing was used for legs testing and medicine ball shoot-up in supine position was used for arms testing. Results: This research shows that best results in the countermovement vertical jump height with arm swing were achieved after the speed-power warm-up. The best results in medicine ball shoot-up in supine position were achieved after the basic warm up, but results are not statistically significant for these testing. Keywords: Warm-up, dynamic stretching, speed-force loading, toning, explosive force, testing

Dissertation thesis is focused on development, design and production of the new milling cutter which is used for roughing operations. High-speed steels, coating technology and milling technology are described in first chapters of dissertation thesis. The main part of this thesis is the design of the new milling cutter that has been designed on the basis of the machining simulation. The milling cutter is designed as a three-flute cylindrical end mill made of high speed steel. The each flute is composed of two special compensation edges. The compensation edges are used for reducing (at best suppression) tensile stress in the heel of the tooth. The milling cutter was made by lost wax technology, followed by grinding and thermal treatment. New designed tools were deposited by PVD coatings (e.g. (Al,Ti)N). Standard catalog milling cutters (producer ZPS - milling tools, Zlín, Czech Republic) were used for comparison the designed milling cutter. Carbon steel CSN 41 2050 (DIN 1.1191) was used for milling, which was carried out with using process liquid. The monitored parameters were force loading, flank wear and tensile stress during milling. The dynamometer Kistler was used for measuring force loading and data obtained during machining was used for stress analysis.
