Ondřejka, Josef ; Majerčík, Petr (advisor) ; Vágner, Michal (referee)
Title: Comparison of the impact of exposure to the shoe inserts foot arch deformation. Aims of the thesis: The aim of thesis is to compare the effects between two selected inserts into the boots of foot arch deformation. The first one is a specially shaped insert and the second one is common available insert in the Czech Army. Method: Bachelor's work was treated as an empirical quantitative research observational character. We tested 19 probands. The measurements were used to measure pressure insole PedarX. It was measured at a speed of 5 km/h with two different inserts in shoes. The monitored values was the total contact area between foot and shoe inserts, and the maximum force influencing the foot during the step cycle. The measured values were assessed using Cohen coefficient. The results were compared to studies dealing with the emergence of deformation at the foot arch. Results: Special shaped insert was compared to common available insert in the Czech Army. It was found, that the special shaped insert increases total contact area between foot and shoe insert. Further the special shaped insert reduced the maximum total force acting on the foot during the step cycle in both feet. Increasing the total contact area and decreasing the total maximum force influencing the foot during the step cycle...

Kellner, Petr ; Vágner, Michal (advisor) ; Majerčík, Petr (referee)
1 Abstract Title: The effect of running with a load on postural stability. Objectives: The establishment of changes in postural stability after a 3 km maximum effort run with a 15 kg load. Research sample: The tested subject group was constitued by seven soldiers of the Army of The Czech Republic at the average age of 25,6 ± 2,1 years who are students of the Military specialization at the Faculty of sport and physical education of The Charles University. Methods: This master's thesis was drawn up as a observational study of theoretic empiric character, realised through intraindividual comparative analysis on a group of 7 subjects. Postural stability was examined with RS Footscan forceplate and clinical balance test U.S. Military Academy Stance Test. The run was realised on a treadmill, without and with a load. For statistical analysis nonparametric statistic tests of significance were used. Results: The results of relations between postural control changes and 3km run with a load of 15 kg display a deterioration of postural stability tested after the run. The extend of deterioration of postural stability after 3-km run with a load within tested group is similar to one after 3-km run of analogous intensity. Key words: run, load, postural stability, balance

Thesis title Comparison of energy output of one rope techniques using different types of ties. Aims The aim of this thesis is the comparison of energy output of rope climbing with load using full body harness and sit harness. Methods used In this thesis an energy output measurement is being carried out using CORTEX METALYZER® apparatus during rope climbing. In the first measurement probands were tested during rope climbing with load using sit harness only. In the second measurement probands were tested during rope climbing with load using full body harness (i.e combination of both sit and chest harnesses). To compare the results obtained, qualitative analysis a a T-test were used. The results Based on the data obtained and the T-test later performed, no significant difference was found between the measurement readings of sit harness climbing and full body harness climbing. According to the qualitative analysis performed, correlation was found out between preffered sport activities a the measurement results, wherein the persons doing aerobic activities showed lower readings of energy output during rope climbing in the second measurement during rope climbing with load using full body harness, whereas the persons doing aerobic-anaerobic activities showed lower readings of energy output during rope...

The influence of using military boots on the power of front kick
Kotas, Jan ; Majerčík, Petr (advisor) ; Vágner, Michal (referee)
Title The influence of using military boots on the power of front kick Objectives The aim of this work is to identify and compare front kick while using military boots to front kick with no usage of those boots. Methods This bachelor work can be described as empirical and observational. A multicomponent force plate was used to detect the power of the front kick. The powers of the kick with the boots and without the boots were compared with the aid of a statistic method called paired t-test. Results In four cases the power of the front kick decreased by the influence of the boots, in one of these four cases was the declension statistically significant. In two cases was the power of the front kick increased due to usage of the boots, while in one of these cases was this increase statistically significant. The result of the interpersonal comparation was statistically insignificant. It was ascertained, that a previous experience with combat activities, which use kicking techniques, and also experience with usage of boots while kicking do affect the power of the front kick. However the results acquired by the measurement and statistical data processing cannot be generalized. Keywords close combat, front kick, military boots

The influence of body armour on a direct front kick strenght
Oláh, Vladan ; Majerčík, Petr (advisor) ; Vágner, Michal (referee)
Title: The influence of body armour on a direct front kick strength Aim: The aim of the thesis was both to find out and compare the strength of a direct front kick made either with a ballistic vest or without it. Furthermore, the thesis focused on the strengths of a direct front kick made with a load-bearing vest compared to a ballistic vest. The methods used: The thesis can be characterised as an empiric work based on observation. The kick strength was measured by a dynamometer and the results have been statistically evaluated by a paired t-test. Results: The first part of the thesis, which was dealing with a direct front kick made with a ballistic vest or without it, resulted in the fact that there is a positive effect of using that kind of a vest. The kick strength was definitely more intensive using the ballistic vest. However, this can be claimed only in such ideal conditions which were available during the measurements. The probands were also not influenced by any physical strain, which is quite typical of martial activities. The second part focused on the differences using a ballistic or a training load-bearing vest when performing a direct front kick. There were no significant differences between the kicks with these two vests. Key words: Close combat, body armour, load-bearing vest,...

Beneš, Jiří ; Majerčík, Petr (advisor) ; Barták, Erik (referee)
Titles Effect of maximum heart rate on accuracy of fire Objectives The goal of this work will be to examine the influence of maximum heart rate on accuracy of fire from the personal defensive gun (pistol), whereas a reference will be used the deviation in accuracy of fire. The group of respondents consists of members of the Police of the Czech republic. Methods It is the empirical work of observational character. To establish statistical significance we used independent samples, paired T - test. For statistical evaluations of the results we used methods of comparison and comparison of averages. To evaluate the shooting targets we used numerical method of detecting the mean point of impact. To establish the maximum heart rate we used sporttester. Results From the measured data was drawn this conclusion. The maximum heart rate has statisticaly significant effect on accuracy of fire. The accuracy of fire is expressed by average distances of single points of impact from the central point of impact. We found out that the performed activity could have had the impact on the size of the differences before and after the activity. Keywords shooting, physical stress, resting heart rate, maximum heart rate
