Comparison of support phase in the take-off to the hurdle and touch-down after hurdle clearance in disciplines 110 m hurdles and 400 m hurdles
Musil, Daniel ; Hojka, Vladimír (advisor) ; Kaplan, Aleš (referee)
Tittle (Thema works): Comparison of support phase in the take-off to the hurdle and touch- down after hurdle clearance in disciplines 110 m hurdles and 400 m hurdles Thesis'objectives: The objectives of the study are to identify differences in centre of pressure trajectory, in amount and distribution of pressure on foot during the take-off to the hurdle and touch-down after hurdle. This was measured on 110m (100m) and 400m tracks. Methods: Measurements were made with the help of Pedar-x system. Subjects were tested in three trials from the first hurdle to the third hurdle on 110m (100m) and 400m tracks. Hurdle with the shortest flight phase was later analyzed. Results: Difference in the take-off to the hurdle between 110m (100m) and 400m is in distribution of pressure and in centre of pressure trajectory only during the braking phase. Difference in distribution of pressure in touch-down after hurdle on 110m (100m) and 400m track was found between active and passive landing. The centre of pressure trajectory in touch-down after hurdle is longer on 400m track. Key words: hurdles, biomechanics, support phase, Pedar-x

The Appearance of the reflex locomotion elements in the hurdle clearance stride
Musil, Daniel ; Hojka, Vladimír (advisor) ; Kaplan, Aleš (referee)
Title: The Appearance of the reflex locomotion elements in the hurdle clearance stride Thesis Objective: The main objective of this thesis is to state the frequency of the presence of reciprocal inhibition (RI) and cross extensor reflex (CI - contralateral inhibition) during hurdle overrun. Methods: The subjects were tested during running over three hurdles with modified distances similar to the 110m hurdles. The height of the hurdles was set to 0,99 m. The muscle activity was monitored by surface electromyography and video was recorded simultaneously. The hurdle clearance was divided into particular phases which altogether formed one cycle. Collected data was analyzed by the software Megawin (rectification, smoothing, and synchronization with camera) and subsequently converted into software MATLAB. Nine cycles of each subject were averaged. Such modified cycle was evaluated consequently. Results: Reflex locomotion (RI and CI) was presented more often in the group with less experience with the hurdles. Co-activation of antagonist muscles was typical for the group consisting of more experienced individuals, rather than RI and CI. Key Words: hurdles, biomechanics, sEMG, reciprocal inhibition, contralateral inhibition

Economic cooperation of the Czech Republic and the People´s Republic of China on the example of selected companies
Musil, Daniel ; Zamykalová, Miroslava (advisor) ; Kotoun, Josef (referee)
This diploma thesis deals with economic relations between the Czech Republic and the People's Republic of China. It is divided into theoretical and practical part. The theoretical part involves two chapters which deal with bilateral relations of both countries on general level. In the first chapter I compare the czech and chinese business environment and mutual economic cooperation using main economic indicators. This chapter is also dedicated to political relations and the problems which China is facing nowadays. The second chapter deals with current economic and export strategies of both countries and their penetration. The last part of this chapter is dedicated to czech institutions which support czech export. The third chapter is the practical part of this thesis in which I focused on putting knowledge of the theoretical part into practice using case study of czech company Škoda Praha, a.s.

Impacts of the global crisis on the foreign trade of the Czech Republic
Musil, Daniel ; Bolotov, Ilya (advisor) ; Čajka, Radek (referee)
This bachelor thesis aims to clarify, what were the impacts of the global crisis on the foreign trade of the Czech Republic. This thesis is divided into three chapters. The first chapter describes the events that led to the global crisis and how it affected the international trade. This is achieved by analyzing the so-called Dot.com crisis from the turn of the millennium, its impacts on the international trade and its association with the global crisis. The second chapter explains the development of the Czechoslovak economy, with a special focus on the foreign trade, since the end of the World War II. This chapter is very important for understanding the context and conditions the Czech Republic had to face at the beginning of the global crisis. The third chapter analyzes the main impacts of the global crisis on the development of the foreign trade of the Czech Republic.
