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...

The effect of running a load on postural stability
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

Šorm, Daniel ; Vágner, Michal (advisor) ; Barták, Erik (referee)
Title of thesis! Use of general and specific kinetic tests for prediction techniques of close combat. Objective Of thesis: My thesis deals with finding content validity and curriculal validity behind sampled kinetic tests for choice of human for the course of close combat. MethodI Thesis is working up like empiric kvantitative research of observation type and notice diachronic dependences between criteria variable and choice continuous independent variables. For analyses of relations and dependences among variables were used methods descriptive and inference statistics. Criteria variables were obtained with sum of evaluations close combat techniques such as composote score. Techniques were evaluations on the scale proposed by Vagner (2008). For preliminary of date analysis was used method of multiple correllations. Algorithm of all possible regressions was used for the propose of set variables and regression triplet was used to evaluate regrression model. Dates were processed with programs such as SPSS 15.0 for Windows, NCSS (Hintze, 2004), and QC Expert 2.7. Results! Specific kinetic tests reached higher curriculal validity to the acquirement of close vombat techiques than general kinetic tests. Every test proved the content validity as satisfactory. With algorithm of all possible regressions we...

Usage of kinetic tests coordinative abilities to selection soldiers to the position of air gunner.
Urbášek, Vítězslav ; Vágner, Michal (advisor) ; Barták, Erik (referee)
Title: Use of kinetic tests of coordinative abilities for selection of soldiers to the position of an aerial gunner The aim of work: The work attempts to determine correlations between selected kinetic tests and activities of an aerial gunner in Mi 171Š. Method: The thesis has a form of a qualitative research of an observation type. The goal of the work was to determine the usability of kinetic tests of coordinative abilities for selection of soldiers to the position of an aerial gunner. A group of ten aerial gunners was subjected to three kinetic tests and activities connected with manipulation with the machine gun PKM 7.62 mm. The gunners were arranged in particular orders according to results they gained in the individual tests. We looked for correlations in these orders. In the course of the subsequent analysis, we mapped relationships between selected kinetic tests and the level of activities of an aerial gunner in Mi 171Š. To analyze the relationships and dependencies between the variables, we used Spearman's rank correlation coefficient and material evaluation. Key words: Movement abilities, kinetic tests, activities of an aerial gunner

Comparison of energy expenditure when moving on wet and dry clothes.
Hrubý, Pavel ; Sýkora, Karel (advisor) ; Vágner, Michal (referee)
Title: Comparison of energy expenditure when moving on wet and dry clothes. Objectives: The aim of this study is to determine the difference in heart rate when moving in dryand wet clothes in different speeds. Methods: Quantitative research and subsequent intra-individual comparison of pulse frequency when moving in dry and wet clothes. Movements were conducted on a treadmill and heart rate was measured by using sporttesters. Results: From the results we can deduce that at the speed of 8 km / h is on the short track the move in the dry and wet clothing approximately at the same energy intensive. Furthermore, it was found that at higher speeds, the difference in heart rates is bigger and wearing a wet clothes at speeds 12 km / h approaches maximum heart rate. Keywords: Energy expenditure, heart rate, military swimming, moving in difficult conditions.

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
