Results: Both players improved their technique and the accuracy of their tennis strokes. Player #1 improved his stroke accuracy by 1 whole level in the "ITN On Court Assessment". In the first testing (at the beginning of the training period) the player scored 126 points, while in the testing at the end of the training period he scored 172 points. Player 2's improvement in stroke accuracy was less, scoring 162 points in the first testing and 175 points in the testing at the end of the training period. Player 2's stroke technique improved twice as much. Players gained awareness of the game of tennis, know the basic rules of the game and know how they should move on the court.

Title: Compensatory exercise as one of the possible means of injury prevention for tennis players Aim: The aim of this thesis was based on professional articles and available literature to identify and describe the most common injuries that occur in adult tennis players of all performance levels and then focus on creating a set of compensatory exercises (relaxing, strengthening and stretching) that could lead to reduction. risk of injury. Methods: The thesis was based on empirical character. Both findings from professional literature and articles published in peer-reviewed journals were used. The proposed compensatory exercises were selected on the basis of professional literature and articles, which focused either on the elimination of imbalances and injury prevention in tennis players, or on exercises typical and suitable for tennis player development, whether from performance (skill) or physical (physiological) point of view. Conclusion: Based on the literature and articles, it was found that the most common mechanism of tennis injuries is due to overload, which means that tennis players train more time than optimal and does not sufficiently compensate. As a result, there is a large unilateral load and this can cause many negative changes in the locomotor system. Tennis injuries to players can...

Hrychová, Denisa ; Carboch, Jan (advisor) ; Kočíb, Tomáš (referee)
Title: The relationship of the toss to the success of the first service in tennis Objectives: The main aim of this work is to determine how the toss impacts the success rate of first tennis serve for both amateur and professional players. Methods: The initial data set was obtained by method of indirect observation using video recording of 8 professional and 2 amateur players. Each of them did 40 direct serves which were recorded and processed using Dartfish 10 software. Followingly the serves were sorted into categories - successfull, into net, out - long ball and out - on the side. Acquired data was processed using statistical (ANOVA) and effect size (Cohen's d) significance. Results: Based on substantive significance it can be said that for the y-axis the players only reached values of low effect with their serves. Larger effect of substantive significance, namely d=0.94, was reached by average values among serves which were played into the net or were out on the side. Balls, which were hit by professional at highest average hight of 273.7 cm ended up as long ball out. On the contrary, tosses hit at average distance of 63.7 cm from the baseline ended up in the net.

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

Svobodová, Iveta ; Buchtel, Jaroslav (advisor) ; Kočíb, Tomáš (referee)
Title: Characteristics of Men's professional volleyball league in terms of technical-tactical aspects of the sport. Objectives: The main objective was to determine which final game activities led to the selected teams obtaining a point and to determine the ratio of final game activities in their triumphant sets. The selected matches were played at the 2015 Men's European Volleyball Championship. The next objective was to compare the selected teams with each other. Methods: In order to meet the objectives, video recordings of played matches were analysed and scores were tallied and compared across all selected teams. Tallying of scores was applied to all video recordings of selected plays in which four teams were analysed in total. The frequency method was used in order to detect which final game activities led to winning of the ball. The comparison method was later used for comparing the selected teams with each other. Results: In detected ratios of final game activities that led the teams to obtain a point we can see the deviations from the average (attack 60%, opponent errors 24%). We found out that the gratest amount of points gained was due to the attacks and opponent errors. We can confirm the trend of top league teams showing the gratest amount of points won due to the attack from the quick...
