Author: Bc. Zuzana Vacková Title: Effect of Barefoot shoes on the footprint loading Objectives: The aim of this experiment is to evaluate if barefoot shoes affect the size of vertical component of contact force during walking on a smooth non- abrasive surface during normal conditions. Furthermore to find out which parameters can be used to monitor the degree of convergence foot behaviour during the stance phase of gait cycle with the barefoot and barefoot shoes. Methods: Seven probands (4 women, 3 men) aged 23 to 25 years participated at the study. The dynamic gait parameters (reaction forces from the pad) were measured using Kistler force plates in the extreme load laboratory at FTVS UK. Probands after introduction to the experiment went repeatedly over the power plate subjectively comfortable speed. The first measurement were done while walking in the barefoot type of shoes. The second measurement was barefoot walking. It was a one-time measurement. The obtained data were exported from BioWare® program into MS Excel. The final data processing was carried out in the MatLab program, where the necessary graphs of reaction forces and their evaluation were created. Results: All contact forces and their resultant and CoP coordinates were recorded during measurements. Only the vertical contact force...

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...

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 Impact of gear and weaponry on posture in kneeling shooting position Objectives The aim of this thesis is to find out the impact of gear and weaponry on posture in the kneeling shooting position. Specifically, this study examines the influence of carried load on posture, aiming stability and balance in the high and low kneeling shooting position variants. Methods This thesis has an empirical observational character. The shooting position was tested by Qualisys camera system and Kistler pressure plates. The measurment was performed on 16 Military department students with mean age of 23 years (standard deviation 2,63 years). Measurements were carried out in four levels, with no load, light load of 15 kg, mean load of 30 kg and heavy load of 45 kg. The measurement was performed on high kneeling variant and the low variant with elbow supported by the front knee. Intra-individual comparison of the results of each level was determined by a T-test. Results: The load in a form of gear and weapony had a statisicaly significant - negative influence on the kneeling shooting position posture. Gear and weaponry used for this study caused a lower trunk position, increased shoulders angle in the low variant, lesser aiming stability and balance control in the position. The bigger was the weight of gear and...

Flasarová, Klára ; Pavlů, Dagmar (advisor) ; Kubový, Petr (referee)
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...

Oláh, Vladan ; Vágner, Michal (advisor) ; Kubový, Petr (referee)
Title: The influence of equipment and arms on skeletal muscles activities while practising direct kick. Aim: The aim of this thesis was to find out the influence of carried equipment and arms on the activity of skeletal muscles when a direct front kick is being practised. The methods used: This thesis has an empirically observational character. Muscular activities were measured by means of surface electromyography synchronised by Qualisys screen system. To obtain statistic data, a t-test has been used, requiring 5 % significance level. Results: While carrying a 15-kilogram load, the activity of skeletal muscles was not significantly reduced when performing a direct front kick. However, a 30- kilogram load caused a substantial reduction of skeletal muscular activities during the kick described above. After adding a 15-kilogram bag to another 15 kilograms in the form of a body armour, a helmet and arms, the muscular activity changed its features in a considerable way. Furthermore, most respondents proved 45-kilogram load to be over their limit. The equipment and arms of that weight led to the summation action potential, exceeding the power- coordinative functional reserve, and thus the deformation of the direct front kick technique. Keywords: close combat, EMG, equipment, arms, direct front kick
