Zvoníček, Matěj ; Gryc, Tomáš (advisor) ; Bujnovský, David (referee)
Title: Profile of youth footballers as goalkeepers Objectives: The objective of this study was to compare selected parameters of body composition, level of static postural stability and level of lower extremities explosive strength between male and female goalkeepers in soccer and between selected age categories. Methods: A total of 33 male (n = 22) and female (n = 11) soccer goalkeepers participated in the study. They were divided into six test groups based on gender and age category (14-15, 16- 17 and 18-19 years) for performance assessment. These groups were assessed for basic anthropometric data (body height and weight), body composition parameters (% body fat, fat free mass), and level of static postural stability (deviations of the total center of pressure path) in four types of stands (narrow stand open eyes/closed eyes, right/left lower limb stand) and lower extremities explosive strength (jump height, relative force impulse, relative maximum force produced) in four types of jumps (counter movement jump free arms, counter movement jump, squat jump, drop jump). We used a Tanita MC-980MA bioimpedance device (Tanita Corporation, Japan) to assess body composition parameters, a Footscan pressure plates (RSscan International, Belgium) to assess postural stability, and a KISTLER 8611 force plates...

Title: Comparison of explosive power in elite youth soccer players Objective: The objective of this thesis was to determine the level of difference in selected parameters of the explosive strength of the lower limbs of elite youth soccer players between the age categories U14 and U15. Methods: The research set of this diploma thesis consisted of a total of 39 elite youth football players in the age category U15 and U14, who at the time of the test were players of the highest domestic football competition. The research group consisted of players of all playing positions (goalkeeper, defender, midfielder, forward). To analyze selected parameters of the explosive power of the lower limbs, a total of three types of vertical jump were used in laboratory conditions: vertical jump from a squat (English "squat jump"; SJ), vertical jump without arm swing (English "counter-movement jump; CMJ) and jump long jump ("broad jump" in English; BJ). The following parameters were analyzed: vertical jump height (cm) and long jump length (cm). Results: Statistical analysis found significant differences (p < 0.01) between monitored parameters. The analysis found a significant difference (p < 0.01) between squat vertical jump (SJ) and non-arm swing vertical jump (CMJ) height between the U15 and U14 groups. Older U15...

Analysis of soccer match loading according to player position.
Bujnovský, David ; Malý, Tomáš (advisor) ; Buzek, Mario (referee)
Title: Analysis of load football players in a match in terms of gaming post. Objectives: The aim of this essay is to determine the size of the musculoskeletal load of players during friendly football matches. At the same time the aim is to determine the differences in the size of the musculoskeletal load between the different players' positions measured in the file. Methods: This essay deals with the indirect (mediated) observations, due to the fact that data was recorded by devices from which this data was then processed to obtain the result. To evaluate the size of the musculoskeletal load sport testers "Polar Team 2" were used. For the statistical evaluation the processed material significance using the so-called "size effect" was used. Results: Regarding the size of the musculoskeletal load, no substantively significant difference was found between the defenders and midfielders in the zone above the ANP. Significant material differences were observed between defenders and attackers, materially significant differences were also found between the midfielders and attackers in the zone above the ANP. However, based on the conditions under which measurements were carried out, it is clear that definite conclusions cannot be drawn. Keywords: Football, physical load, heart rate, player's positions

Title: Comparison of the size of the motor load in the Czech and Austrian soccer players at the same performance level Objectives: The aim is to determine the size of the physical load of players during a football match. At the same time the next aim is to determinate the differences of physical load between Czech and Austrian soccer players at the same performance level. Methods: The indirect (mediated) observations was used in this bachelor thesis, because the data were recorded by computers, from which data were subsequently processed to form of the results. Sporttester "Polar RS800" were used to assess the size of the physical load. For statistical analysis the "effect size" was used. Results: In terms of size of the physical load the significant difference was found between Czech and Austrian soccer players in average time spent on level of higher physical load (heart rate over 85% of maximum heart) during the football match. However, based on the conditions under which measurement were made, it is clear that it is impossible to draw definite conclusions. Keywords: Football, physical load, energy expenditure, heart rate, player's positions

Hlubuček, Daniel ; Kokštejn, Jakub (advisor) ; Bujnovský, David (referee)
Name: The effect of age at the level of technical skills and speed of goalkeepers in football. Objectives: The aim of the diploma thesis was to determine possible differences in the level of technical skills and movement speed of football goalkeepers across age categories (11 - 19 years). At the same time, the aim was to find out any differences between goalkeepers from the professional and amateur club. Methods: The level of technical skills was determined using two specific goalie tests, the Sprint Keeper Test (S-Keeper test) and the Laterl Shuffle-Keeper Test (LS-Keeper test). Movement speed was determined using sprints 5 and 10m. Results: A significant effect of age on performance in the S-Keeper and LS-Keeper test was found between the individual age categories (p <0.01; p <0.05, respectively). Significant differences were found between pupil and adolescent categories, except for the difference between older pupils and younger adolescents in the LS-Keeper test (non-dominant foot). Furthermore, no differences were found between younger and older pupils and also between younger and older adolescents (in the S-Keeper test and LS-Keeper test). In the tests of movement speed 5m and 10m, significant differences were found between all age categories. In the S-Keeper test, LS- Keeper test and sprint...
