Analýza forhendu elitních tenistů ve vybraném utkání / Analysis of the elite tennis playersfor the selected match

Chlumecký, Tomáš January 2018 (has links)
Title: Analysis of the elite tennis players for the selected match Objectives: The aim of the work was to find out the frequency, effectiveness and success of the elite players in the selected French Open 2018 match. This was the final match of this tournament, where i analyzed every forehand. Methods: The analysis was done by observing video recordings of final matches from the French Open 2018. This was a notation analysis. The results were recorded in pre-created tables and then converted to charts. Results: The results show us which player has used the forhend, where the forhend was more successful, more efficient, and in which direction it was played. Keywords: forehand, frequency, efficiency, success rate

Hodnocení timingu tenisových úderů pomocí kinematické analýzy a povrchové elektromyografie / Assessment of the timing of tennis strokes using kinematic analysis and surface electromyography

Harrer, Jakub January 2012 (has links)
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

Vliv povrchu na rozložení zatížení nohy při dynamickém pohybu v tenise / The influence of the surface load distribution of the foot during dynamic movement in tennis

Šebíková, Linda January 2017 (has links)
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...

Ovlivnění posturální stability hráčů tenisu věkové kategorie 11- 13 let fyzioterapeutickou intervencí cvičením s Propriomedem / The influence of physiotherapeutic intervention with Propriomed on postural stability of 11-13 years old tennis players

Bednarzová, Barbora January 2018 (has links)
Title: The influence of physiotherapeutic intervention with Propriomed on postural stability of 11-13 years old tennis players Objectives: The main aim of this thesis is objectivize the influence of physiotherapeutic intervention involving exercise with Propriomed on the success of strokes and speed of the swing phase of 11-13 years old tennis players. Methods: Teoretical part is composed like a recherche in which are informations that make base fot the practical part. For the practical part was made experimental study which contains sample of 17 probands in age between 11-13 that are active tennis players for more than 5 years. Pobands was divided into intervention group and control group. Intervention group had training with Propriomed once a week. Main task of study was analysis of succes rate and speed of the swing phase of different tennis shots before and after physiotherapeutic intervention with Propriomed and comparing results of both groups. Results: In beckhand shot was observed statistically significant difference after finishing first intervention. It is possible to claim that training with Propriomed positively influence precision of the backhand shot in a short term. Proband reached the best results of succes rate of forehands after last measurement. From that we could claim that...
