Identification of brain areas in anticipation during tennis
Gavendová, Karolína ; Kočíb, Tomáš (advisor) ; Carboch, Jan (referee)
Title: Identification of brain areas in anticipation during tennis Objectives: The main aim of diploma theses is identification of brain areas responsible for anticipation and making decision during watching tennis rallies at tennis players by functional magnetic resonance. Methods: The research group consists of 10-12 competitive tennis players aged 18-28. The research takes place at the hospital in Motol. Before the examination itself, the probands are instructed on the course and conditions of testing. Testing consists of examining the brain to see if the proband is healthy, testing anticipation with a video of tennis rallies followed by a resting state phase to evaluate regional interactions. The video consists of 6 blocks separated by a static image lasting 20 s. Each block contains 6 videos with tennis rallies. Each video lasts exactly 6 s, including 300 ms to stop the tennis rallies. The tennis rallies are stopped when the ball is over the tennis net or on the player's racket. The task of the proband is to monitor the tennis rallies and after stopping to determine whether the subsequent stroke will fly to the left or right side of the tennis court, or to the center. The target data are formed from functional magnetic resonance images, probands' responses to individual rallies, and response...

The effect of "brain gym exercises" on tennis players' postural stability
Formanová, Klára ; Vomáčková, Helena (advisor) ; Pánek, David (referee)
Title: The effect of "brain gym" exercise on tennis players' postural stability Aims: The aim of this diploma thesis is to find out whether "brain gym" exercise completed for 30 days has an impact on tennis players' postural stability Summary: Altogether 12 women, 18-30 year olds, participated in the pilot study. The probands had completed a 30-day exercise intervention program which included a daily exercise for a maximum of 10 minutes. The postural stability was measured before and after the intervention using Neurocom Smart EquiTest System (Sensory Organization Test, Motor Control Test, Limits of Stability) and Standing Stork Test which evaluace the ability to balance vertically on the tip of one lower limb. The measured data were processed by the program Neurocom Data Analyzer, from which the data were subsequently transferred to Microsoft Excel 2010, SPSS 2007 and GPower 2019. To evaluate the effect of intervention the statistical methods - Shapiro-Wilk test, Student's paired t-test, Wilcoxon test were used and Cohen's d was used to determine clinical significance. The level of statistical significance was determined to α = 0,05, when p < 0,05 - statictical significance, p > 0,05 - statistical insignificance. The values of clinical significance were set to: high significance - d > 0,80, medium...
