Perception of vehicle speed
Šlapalová, Eva ; Sedlák, Robert (referee) ; Bilík, Martin (advisor)
This diploma thesis deals with the perception of the speed of the vehicle from the point of view of the driver without the possibility of checking the speedometer. The theoretical part is devoted to the driver as a risk factor and vehicle research. The practical part consists of conducted driving tests concerning the subjective perception of the driver according to age, experience and type of vehicle.

Perception of vehicle speed
Hlavinková, Petra ; Dadák, Leo (referee) ; Bilík, Martin (advisor)
The presented master thesis deals with the perception of the speed vehicle crew (not the drivers) in traffic in terms of different aspects, that influencing the feeling while driving in the vehicle. This is primarily about the approximation of factors that may have an impact on the speed. The aim of the thesis is to propose an appropriate methodology of measurement and subsequent evaluation of acquired date, which leads to an improvement in the idea of whether witnesses of traffic accidents are indicative of the speed of the vehicles, at reasonable real speed.

Acute effect of warming up on the speed of tennis serve
Gavendová, Karolína ; Jebavý, Radim (advisor) ; Kočíb, Tomáš (referee)
Abstracts Title: Acute effect of warming up on the speed of tennis serve Objectives: Compare the influence of a dynamic warm-up with tennis racquet, dynamic warm up with elastic resistance and dynamic warm-up with medicine ball on the speed of tennis serve. Methods: To fulfil the aim it was to use the radar Stalker Pro II. The obtained results after each warm-up has been processed to the average and maximum values and then compared with each other. Results: In this work, it is not possible to confirm acute positive influence of the specific dynamic warm up. In terms of average and maximum values after single warming up it was evident, that the lowest values were obtained after dynamic warm up with elastic resistance and the maximum values were achieved after dynamic warm up with medicine ball at category of kids and after dynamic warm with tennis racquet at category of adults Keywords: tennis serve, speed, warming up, dynamic stretch

Measuring the velocity of projectiles by laser beam
Šmerda, Jaroslav ; Šebesta, Jiří (referee) ; Lukeš, Zbyněk (advisor)
Muzzle velocity is the speed of bullets, guns at the moment it leaves the barrel of a gun. Since this is a parameter related to the storyline, which takes place only shortly after the bullet leaves the barrel, this figure is the transition ballistics. The aim of this work is to design and construct a device for measuring the speed. Measurement consists in measuring the interval at which the bullet crosses the two laser beams. From this data, the performance will be calculated.

Influence of acceleration abilities on performance in agility tests (speed of change of direction of movement)
Hrubý, Jakub ; Hojka, Vladimír (advisor) ; Kokštejn, Jakub (referee)
Name: Influence of acceleration abilities on performance in agility tests (speed of change of direction of movement) Objectives: The main goal of this work is to determine the level of agility performance with acceleration and maximum speed for football players of different age categories. Methods: To solve the problem, I used a correlation analysis. The first measurement was acceleration and peak speed measurement using photocells. The second measurement was focused on performance in change of direction speed. The resulting data from photocell measurements was processed using IBM SPSS statistics 22 and Microsoft Excel. Results: I have found that the greatest impact of the selected COD's tests has an illinois test at r = 0.596 with an almost 100% connection on the acceleration, maximum speed for 16- 17 year old footballers. In addition, it was found that the 505 test had the best connection with the AR_5 test, r = 0.418 with almost 100% acceleration related. The third best result was the arrowhead test, which got r = 0.301, a small correlation value with 90% of the acceleration and maximum speed. The worst result was found in the hexagon test, which had negative r values, ie, an absolutely insignificant correlation. Keywords: football, fitness, speed, COD's, agility, performance structure

Identification and comparison of selected abilities in elite soccer players category U14 and U15
Paseka, Jaroslav ; Malý, Tomáš (advisor) ; Buzek, Mario (referee)
Title: Identification and comparison of selected motor skills in elite U14 and U15 football players Objectives: The aim of the thesis is to objectify and compare selected indicators of motor skills in young elite football players category U14 and U15. Methods: 26 probands at age 14 and 15 were tested. Testing took place in one training unit. In the thesis are used the methods of observation and testing. In the result section we use a comparison method where the results of individual players were compared using statistical methods. During the testing Brower timing system, Optojump, sports radar and Fitt light cones were used. Results: The results of our thesis showed the differences in the physical abilities in terms of player posts as well as individual players. We divided our test file into defenders, midfielders and attackers. The highest level of endurance capability was shown by younger defenders and midfielder, strength capabilities of older defenders and attackers, speed acceleration capabilities and agility of younger invaders. Key words: football, testing, mobility skills, agility, endurance, strength, speed, category U14 and U15

Analysis of player's load in national handball match
Hokr, Jaromír ; Tůma, Martin (advisor) ; Malý, Tomáš (referee)
Title: Analysis of player's load in national handball match Aim: The aim of the work was to measure the internal and external load of the national handball players during the second league match and then to analyze the data. Methodology: 7 players from TJ Šroubárna Žatec took part in the measurement, including 1 defender, 3 midfielder and 3 strikers. Prior to the load measurement, the maximum heart rate was determined for each player using the Yo - Yo Intermittent Load Test by using the Polar Team 2 Sporttesters. The load measurement took place in a second - league match between TJ Šroubárna Žatec and TJ Spartak Rožmitál pod Třemíšnem. The measured data was processed in MS Excel. The level of statistical significance was set at p <0.05. Results: The results show that the longest distance players have traveled in the zones of staying (49.2% distance), walking (26.5% distance) and running (15.4% distance). They spent the longest time in the zones of the staying (54.5% of the time), walking (21.6% of the time) and the troting (19.5% of the time) and their heart rate was mostly in the zones 80-90% SFmax (28.2% time), 70-80% SFmax (23.1% of time) and below 60% SFmax (18.5% of time). The average speed of the players was 2.3 km / h and the average heart rate was 146 beats per minute. The average distance...

Seasonal variation of speed and endurance in young elite soccer players
Kunzmann, Egon ; Malý, Tomáš (advisor) ; Kokštejn, Jakub (referee)
Title: Seasonal variabilityof speed and endurance skills of young elite soccer players. Objectives: Comparison of variability in speed and endurance capabilities of young elite soccer players during one season in the U-12 category based on the results of a test battery consisting of 4 tests (30 m sprint test, Agility 505 Test, Illinois test and Yo-yo intermittent recovery test level 1). Methods: Our thesis is characterized by using comparison and testing methods. We use the comparison method in the result section, in order to compare the performance of individual players by means of statistical methods. This is how we focus on each of our test exercises during all four testing phases included in seasonal macrocycle. The results: As the result of our thesis, we found out that the physical abilities of individual players and their demonstration in the performed tests improve or remain the same or statistically very similar throughout the season. We observe the highest variability in agility 505 test with a 6.96 % DL and 7.29 % NDL as well as a 25.86 % in Yo-Yo intermittent recovery level 1. According to our observations, deviations in the performance of soccer players are mainly caused by long-term and systematic training process, different training and match load of the players during the...
