Junior tennis technique
Hanzlík, David ; Kočíb, Tomáš (advisor) ; Carboch, Jan (referee)
Title: Junior tennis technique The bachelor's thesis analyzes the technique of shots among junior tennis players, in particular intermediate and advanced players (both males and females) aged between 11 and 15 years of age. It focuses on three basic shots in tennis: forehand, backhand and serve as those are the most frequent shots in the game. This thesis describes individual parts of the research and highlights methods being video recording, testing, observation. With the help of video the thesis analyzes particular details of the level of skill of the shot making of individual players. Objectives: Analysis and evaluation of forehand, backhand and serve technique between tennis players in tennis school. Methods: Video analysis, observation and testing method Results: Based upon the findings, we can conclude that shot making success rate was much higher than that of efficiency amongst the players. As far as technical execution of the shots goes, players had better rating in backhands than forehands. However, efficiency was better in forehand shots. The worst aspect was the serve where technical execution as well as efficiency was far worse than that of backhands and forehands among half the players analyzed. The most common mistakes were: wrong or inadequate use of the center of gravity,...

Harrer, Jakub ; Kočíb, Tomáš (advisor) ; Pravečková, Petra (referee)
Title: Assessment of the timing of tennis strokes using kinematic analysis and surface electromyography Aims: Assess the timing of tennis forhand, service and appropriate training exercises using kinematic analysis. Describe the activation of muscles in time for the chosen execution of the strokes by recording surface electromyography (SEMG). Compare the results of various executions and describe the differences between using the racquets with different parameters and between executions of various training exercises. Method: Case study using kinematic analysis and surface electromyography was made. Results: We have found out that the execution of the strokes using the players own racquet was the most stable. We have found the differences in timing while using various racquets. The heavier the equipment we are using in training exercise is the more different is the timing of this movement. We concluded that the chosen training exercises are inappropriate as the special exercises to improve coordination. Key words: tennis, timing, service, forhand, electromyographic analysis, kinematic analysis

The evaluation of a tennis groundstroke by qualitative examination of functional movement
Vojtěchovská, Karolína ; Oplatková, Lenka (advisor) ; Kolář, Jáchym (referee)
This bachelor's thesis describes the evaluation of the tennis groundstroke and the influence of postural stabilization on the resulting quality of activation of the trunk in the groundstroke. The theoretical part summarises the knowledge of the optimal performance of the forehand, as well as the method of evaluating the forehand. In the practical part of the bachelor's thesis, we qualitatively assessed postural stabilization of players according to the concept of DNS. We followed the process of qualitative movement diagnosis and we performer video analysis of the forehand from the Slow-motion recording. The specific parameters of the tennis groundstroke were objectified by using the program Tracker and Zepp Tennis 2 sensor, which gave us the values of angular displacement of the body segments, the angular velocity of hip and shoulder rotation, and the ball speed, the ball spin and the percentage success rate of impact location in the sweetspot of the racket. We made a table of qualitative movement that takes into account key features of the forehand, depending on each phase of the groundstroke. Then we made a complex evaluation of the player's forehand. We concluded that it is not possible to establish a uniform ideal angular alignment of body segments. It is always necessary to respect the...

The influence of the surface load distribution of the foot during dynamic movement in tennis
Šebíková, Linda ; Maršáková, Kateřina (advisor) ; Kubový, Petr (referee)
Title: The influence of the surface load distribution of the foot during dynamic movement in tennis Objectives: The aim of this work is to determine whether there is a change in the force load in the area of the sole of the foot during the forehand strike phase in an open position depending on the type of playing surface. Methods: The research was attended by 10 level I tennis players of ranging from the age of 17 to 28. Each of the players has played tennis for at least two years, train 2 - 3 times a week and has no limb injury in the past 12 months. Using the Pedar-X instrument, changes in the force of the plantar load during the forhend strike phase on clay and Casali surfaces were measured. To evaluate these changes, the contact forces [N] (vertical reaction forces) were measured. First, an intra-individual foot impact assessment on the heel region and forefoot on the clay and Casali surface were performed using graphs of temporal force averages. Secondly, an inter-individual evaluation of the maximum force values in the region of the heel, midfoot, forefoot, hallux and lesser toes and whole feet of the foot was performed using the paired t-test statistical method. Results: The results of the work show that the different surfaces influence the size of the load as well as its plantar...
