Perception training in tennis
 Mrázová, Kristina ; Carboch, Jan (advisor) ; Malý, Tomáš (referee)
Title: Perception training in tennis Objectives: The main goal of this paper is to assess the impact of perceptual-cognitive training on the development of anticipatory skills in expert and novice tennis players. Methods: The result of this paper was obtained using an experiment based on the test-retest method. It is a randomized controlled trial in which the intervention groups underwent three weeks of perceptual-cognitive training in addition to the test and retest process. All parts of the experiment (test, perceptual training, retest) were based on watching edited video recordings of tennis serves using the temporal occlusion technique. The tracked variable in the experiment was the relative accuracy of responses. Results: In the intervention group of expert tennis players, a significant difference was reported between test and retest performance (p < 0.01; d = 1.05). No statistical significance was observed in the intervention group of tennis novices or in any of the control groups. Since the intervention and control groups of expert tennis players did not differ in the test stage, the observed increase in performance was attributed to the effect of applied perceptual-cognitive training. The statistically significant increase in relative accuracy of responses between test and retest occurred...

Development of tennis rules with an emphasis on serving
 Mrázová, Kristina ; Kočíb, Tomáš (advisor) ; Carboch, Jan (referee)
Title: Development of tennis rules with an emphasis on serving Objectives: The main goal of this paper is to assess the possible impact of removing the rule of the second service from professional tennis matches on their length. It also focuses on this change's feasible influence on the attractiveness for viewers. Methods: The result of this paper was obtained using indirect observation of video recordings from Australian Open 2021, Roland Garros 2021, and Wimbledon 2021. In addition, was used notation analysis of tennis matches from listed tournaments. For tracked variables were used the rally length after both the first and the second serve. Another variable was the time gap between the first and the second serve. Results: Acquired results of this work show that tennis matches would not be significantly shortened after the removal of the rule of the second serve in relation to other time aspects of tennis matches. This outcome serves as an argumentative foundation for expert discussion about the possible introduction of a change to the existing rules concerning the second serve in the game of tennis. Keywords: tennis, second serve, change of rules, match length
