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...
Acute effect of static and dynamic stretching on vertical jump
Dostálová, Anna ; Lopot, František (advisor) ; Kubový, Petr (referee)
Title Acute effect of static and dynamic stretching on vertical jump. Objectives The aim of this thesis is to assess whether it is better to warm up by static or dynamic stretching in order to improve performance in the vertical jump. Methods The first part of this thesis is theoretical and is the basis for measurement, which is described in the second part. The tested set consists of ten women volleyball players. Each player underwent three vertical jump measurements on power plates Kistler, which recorded flight time of the player over the plates. All measurements were evaluated afterwards. Five attempts were recorded in each measurement. Measurements were carried out without stretching, after dynamic stretching and after static stretching. The thesis includes a survey that monitors the perception of the players` performance. Results Results of the total tested set measurement show that inclusion of dynamic stretching during the warm up leads to a slight decline in the physical performance. This decrease presents about 0.92%. Another conclusion of this research is that the inclusion of static stretching to the warm up also results in a slight decrease in the athletic performance. In this case the decrease is about 1.72%. In a direct comparison of these two types of stretching, the inclusion of...

Štefanský, Michal ; Michalička, Vladimír (advisor) ; Kubový, Petr (referee)
Title: Refine the prediction process for the software Combatfit Aim: Find more accurate method to predict for the need of software Combatfit. Compare software prediction with field measurements and suitable alternative for predicting. The methods used: The thesis is empiric - teoretic research and it is consist of two parts. 1) Teoretic part - analytic work 2) Empiric part - metodologic study Results: The nomogram was chosen as a suitable way of prediction. The research was realized at 3 km, 8 km and 10 km on track in the field. The measured times were used to compare the predicted time by software Combatfit with time prediction according to the nomogram. It was found that the nomogram predictions outperforms software Combatfit. Furthermore it was determined tightness of the relationship between predicted and measured time in either process. The tightness of the relationship with the nomogram was very high up to absolute. The tightness of the relationship with the software Comatfit was moderate. This statement applies to test files that was used. It is not entirely clear whether this would achieve the same conclusions for other performance groups. Key words: Software Combatfit, prediction of performance, movement, external conditions, nomograme.

Title of the master thesis: The evaluation of the effect of yoga asanas on the position of the pelvis Abstract in English language: The aim of this paper is to verify the influence of exercise-specific assemblies of yogic asanas on the position of the pelvis in the sagittal plane, as another parameter, we chose the change in extension of the spine in a plane sagittal. The two-month exercise program is compiled so that it can affect the length and tension of the major muscles, having an effect on the position of the pelvis and correct its excessive anteversion, or retroversion. The content of the exercise program is supported by the theoretical background from the fields of anatomy, kinesiology, biomechanics, and also from the field of yogic theory and practice. The exercise was conducted once a week in groups (90 minutes), under the guidance of a physiotherapist and on the form of autotherapy in an abbreviated version (about 16 minutes) six times a week. The exercise group comprised young people (n=12) aged 20-30 years without any known structural deformities axial body or a serious functional deficit of the locomotive body. The measurements have been carried out in the laboratory of biomechanics using 3D kinematic analysis system Qualisys. The results indicate that the exercise of yoga asanas has...
