Bidirectional pneumatic stepper motor
Veselý, Václav ; Pavlík, Jan (referee) ; Kolíbal, Zdeněk (advisor)
The diploma thesis Bidirectional pneumatic stepper motor concentrates on a step shaft rotation in the presented scheme of a kinematic mechanism. The introductory research part of the diploma thesis lists various types of pneumatic components and the analysis of elements in pneumatic circuits is provided. The following section of the thesis concentrates on designing a new scheme of a pneumatic stepper and construction of a functional mock-up. The final part of the diploma thesis offers a summary and final evaluation of the design and offers subsequent alterations for its further usage.

Title: Development of agility during on-ice and off-ice trainings for ice hockey players in the youth category. Objectives: This diploma thesis is mainly focusing on verify whether off-ice training or on-ice training is more effective and cause better agility improvement on the ice. Another goal of the thesis is to experimentally verify if there is a motoric transfer to agility on ice due to agility training off the ice. Methods: In this experiment, I had seven participants divided into two separated groups. The task for the groups was to undergo two, one month training programs, on - ice and off - ice. Results were measured by method of quantitative analysis of motoric test results. Results: In both of the monitored groups, the results were improved in two out of six tests. For the research, the participants were divided into two groups. Both groups completed a month long training program on ice and off ice. In the direct 6.1m sprint test, direct 35m sprint and S - Corner, the results did not change. In the slalom-puck test, a difference was found in the Cohen d values between the group which began only on ice and in the group that was beginning office after both periods. The result of the reaction test was by Cohen's d same as in the slalom-puck test. Keywords: Ice hockey, agility, training,...

Velocity and agility skills in football
Červenka, Daniel ; Zahálka, František (advisor) ; Kokštejn, Jakub (referee)
Title: Velocity and agility skills in football. Objectives: The aim of the study was to evaluate the velocity of movement of players due to the change in direction. Assessment of the direction changes when moving to a successful test result. Mutual comparison of the decelaration and acceleration at a given distance. Methods: Measured group consisted of 15 players with these athropometric values (age = 17-18 years, height = 178 ± 4.58 cm, weight = 72 ± 2.35 kg). Players completed the warm-up prior to testing (activation stretching, stretching, warm up and subsequent motion game). Measured tested portion was 5m, followed by turning on the predefined leg and running backwards to the photocell gate. Each player completed 2 attemps on the right and 2 attemps on the left leg. Method for evaluating the kinematics used 2D video analysis. For video processing software was used Virtual Dub 1.4 (VirtualDub.org) cut processing records mileage and kinetic analysis was performed using software, Bio TEMA (ImageSystems Ltd., Sweden). Results: The results are as follows : third player had the fastest time in all attempted turns 5,76 m/s. The best result turning on the left had the twelve player who reached 5,54 m/s. In conclusion i would like to concentrate on the speed component after a difficult coordination...
