Altman, David ; Kokštejn, Jakub (advisor) ; Hojka, Vladimír (referee) ; Hráský, Pavel (referee)
Title: Evaluation strength, speed and agility of elite football players. Objectives: The main aim of this work is to determine the level of strength, speed and agility of elite football players (15-16 years). The secondary aim is then to identify the interrelationships between physical strength, speed and agility. Methods: The main scientific methods of theoretical - empiric character are in field testing and observation. The research group included 31 players Motorlet Praha and 30 players Bohemians Praha 1905 categories U16 and U17. Basic descriptive statistics and correlation and regression analysis were used to evaluate the measured data. Results: Little connection has been found between linear sprinter and agility tests (r = 0.28- 0.40). Very similar pattern has been found between linear sprint performance and maximum limb strength (r = 0.16-0.23) and also between the performance in the agility test and the maximum strength of the lower limbs (r = 0.15-0.18). A significantly better performance in the agility test was discovered among older players (16 years) compared to younger players (15 years). The results show the low level of interaction between selected parameters which play an important role in the game performance of football players. Performance in the agility test seems to be...

Žáček, Adam ; Hojka, Vladimír (advisor) ; Červinka, Pavel (referee)
Title: The influence of level of isokinetic force on CODS performance of football players. Objectives: The main goal is comparison of influence between isokinetic power of lower limbs and performance in CODS tests. Method: Measured group consisted of players between 15 - 19 years old from teams Motorlet Praha and Bohemians Praha. Measurement took 3 months. Players of one age category passed the tests batery in one day, that consist of agility (Arrowhead L and R, Illinois, K-test, Hexagon test, 505 L and R), Cybex was used to find informations about isokinetic force. Results: The biggest correlation was between isokinetic (IK) force and performance in CODS tests was measured between IK tests and CODS test Illinois -0,443. Other tests had from very weak to average correlation. The worst correlation was found between IK tests and Hexagon test -0,007, which showed insignificant correlation between these tests. Concentric muscle contraction achieved higher correlation than eccentric muscle contraction and with changinging degree speed was correlation in concentric muscle contraction lower, while eccentric muscle contraction correlation was slightly higher in faster degree speed. Keywords: Isokinetic force, agility, CODS, football, training

Jiskra, Jan ; Kokštejn, Jakub (advisor) ; Malý, Tomáš (referee)
Title: Influence of small side games and runs on sprint performance and agility in football players. Purpose: The aim of the thesis is to find out the influence of selected movement interventions (small side games versus runs) on sprint performance and agility in elite football players in U14 category during the preseason period. Methods: The 30-meter Sprint was used to rate speed-strength performance. Players have executed 2 sprints at 30m. Sprint time was measured at 5, 10 and 30m. Agility tests included: test 505 and three-step test. Players also have executed 2 tries (one of each leg). A set of photocells (Alge Timing GmbH, Lustenau, Austria) was used to measure the time of all tests. Results: Both groups significantly improved in the three-step test (p <0.05; r> 0.5). The SSG group, after a two-month intervention, significantly deteriorated in the sprint to 5, 10 and 30m (r = 0.38 - 0.69). The race group did not significantly improve in sprints at 5, 10 and 30m. In the agility test, we saw a significant improvement only in the Run groups and only on the left leg (r = 0.42). Based on the findings, we believe that the training units of the linear speed and speed with the change of direction maintain the level of player's speed during the season. Therefore, I recommend that they should appear in...

Novák, Dominik ; Šťastný, Petr (advisor) ; Vojta, Zdeněk (referee)
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,...

Vlivy na výkon psa ve vrcholových soutěžích agility
HORTOVÁ, Nikol
This bachelor thesis deals with the use of a dog and dog sports. It is concentrated on the dog sport called agility, on the history of this sport and its regulations in the Czech Republic. It mentions races used in agility and their specific characteristics for this kind of dog sport. There were 1266 specimen studied in total, in three size categories. These categories are small, medium and large. and they are determined according to the shoulder height of the dog. For the analysis, the results from the Championships of the Czech Republic in the years 2010 till 2016 were used. The influence of gender, age and race on the final result was determined. On the basis of a detailed study and analysis, it was found out, that the most suitable dogs for participating in these races with the best results are in the category small and medium sheltie (37 %, resp. 23 %) and in the category large border collie (68 %) and belgian shepherd (9 %). Comparing the results in the competitions regarding the gender, bitches were always more succesful than dogs. As for the age, the dogs in the category small between the 5th and 7th year , in the category medium between the 5th and 6th year and in the categoty large between the 4th and 6th year achieved the best results.

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
