Modification of the landing gear of the Irbis aircraft
Forman, Tomáš ; Vaněk, František (referee) ; Šplíchal, Jan (advisor)
This master thesis deals with the landing gear rebuild from tail gear to nose gear of the M-4 Irbis aircraft. The first chapter presents the aircraft in its current state and includes some technical data, too. The theoretical information about types of landing gears, its characteristics, pros and cons and the typical representatives for each type of landing gear are mentioned in the second chapter. The third chapter is about landing gear loads that occur during landing and about the load calculation according to UL 2 regulation. The following chapter shows the construction of the new landing gear, including some of the suggested, but not realised, designs. In the fifth chapter, there is a landing gear strength calculation of some of the gear components. The calculation is analytical and then uses FEM. The very last chapter then shows the effect of new landing gear on the centre of gravity in its extreme positions. The chapter also compares aircraft masses with both landing gears.

Posturographic training in flatbed therapy for younger school children
ČERNÁ, Adéla
The arch of the foot began to develop parallel to the transition towards an erect posture of the body to bear the weight and to absorb shocks while the foot is in contact with the ground. The human foot consists of two arches - longitudinal and transverse arch. Both start to develop as the child starts to walk. The development is finished around the pre-school age. From literature it is known that up to 80 % of inhabitants suffer from incorrect foot hold/position. One of the most common deformations of the foot appears to be flat feet. Flat feet are usually formed already in childhood. With the common causes being premature toddler footwear, fashion shoes, fast growth, and excessive physical activity etc. Posturographic techniques are methods used for measurement and treatment of qualitative and quantitate postural balance. There exist two types of posturography - static and dynamic. The theoretical part of the thesis covers the specification of foot anatomy and function, the arch of the foot, the definition of Flat feet and a brief description of therapy. It is followed by description of the posturographic function and posturographic tool, which was used during the practical part of this thesis for the therapy itself. The practical part of the thesis was processed as qualitative research where an initial examination of aspects, an interview and both a posturographic and podoscope assessment all concluded in the form of case reports, took place. Three boys, who attended the first grade of an elementary school were included in this study. They attended the posturograph therapy once a week and they went through a given set of exercises at home. First goal of this study was to observe if the posturography training included in the therapy of flat feet has an impact on the results within the children around the age of primary elementary school. The second goal was to evaluate the effect of posturography exercises on the therapy of flat feet among children. Although this thesis has not brought clear results, a slight improvement of the childrens posture could be observed. The explanation of the unclear results could be due to the small size of the test group or due to short and inefficiently intense therapy. Nonetheless some of the children were looking forward to attending the appointments and that in my opinion adds to the benefits of the overall results.

The relationship between Véle-test results and results of instrumented evaluation of postural stability
Dvořáčková, Terezie ; Šorfová, Monika (advisor) ; Tlapáková, Eva (referee)
Title: The relationship between Véle-test results and results of instrumented evaluation of postural stability Objectives: The aim of this study is to determine the relationship between a clinical tool for measuring postural stability, Véle-test and instrumented evalution of the same modality. The observed parameters are COM movement, range of motion in hip joints and in the functional complex of ankle and foot. An additional pedobarographic measurement was performed to define the relationship between Véle-test results and foot loading assymetry. The characteristics of this study suggest that our objective is also to find an approppriate aproach to further objectivization and stardardization of the Véle-test. In the first part of this thesis, I define the theoretical background for the experiment. Also, the current insight of physical therapy and biomechanics on the functional complex of the ankle and foot is described. Methods: The subjects (n=15, mean age 24y) were divided into two groups (S1, n1=7; S2, n2=8) according to the results of Véle test. Further, they underwent instrumented testing by pliance-x® sensing system, a 60s pedobarographic measurement was held in quiet standing. After, the Xsens MVN Link suit for 3D kinematic analysis was applied and the subjects were measured in two different...

Specific changes on feet of rhythmic gymnasts and possibilities of physiotherapeutic influence of the feet with the help of a movement program
Šťastná, Jana ; Satrapová, Lenka (advisor) ; Nováková, Tereza (referee)
Title: Specific changes on feet of rhythmic gymnasts and possibilities of physiotherapeutic influence of the feet with the help of a movement program Objectives: An objective of the thesis is to assess a function and specific changes on feet of rhythmic gymnasts and to demonstrate a positive influence of a movement program on these changes and the deteriorated function of the foot. To summarize the results of existing studies focused on influencing of proper function of the foot and to gain useful information from this experiment not only for physiotherapists, trainers and modern gymnasts but also for laical, actively sporting public which exhibit the same issues with the foot area Methods: The main essence of this scientific-research quantitative study is an influencing of deteriorated function and specific changes on feet of rhythmic gymnasts with the help of a movement program. The program was performed after each practice (i.e. 4 times a week) through the course of 3 months. 10 probands in the age from 14 to 17 years participated in the program. The experiment was based on the method of a comparison of 2 questionnaires and an entrance and exit kinesiological analysis, the part of which was also a test according to Véle (with visual control/without visual control) and a plantogram. For their...

Influence of defferent kinds of running shoes on stability and risk of injury in long - distance runners
Krchová, Zuzana ; Čakrt, Ondřej (advisor) ; Doubková, Lucie (referee)
The main problems concerning birth of running injuries is their unclear ethiopathogenesis and high frequency. Injuries are often lined with forces affected on tread-down which have to be defused by running shoes. There are also opinions that currently used footwear can cause injuries on the contrary. This work explores impact of particular types of running shoes for influencing of stability. Methods: There are compared two groups of runners: minimalists and classic runners. Their stability is examined with help of posturography in three versions: barefoot, classic and minimalistic footwear. Thereafter there is analyzed relation among stability, used footwear, training usage and frequency of injuries. Results: Minimalists and classic runners have the same stability while they are barefoot. Usage of footwear does not cause significant deterioration of stability in any of groups. Nevertheless most of runners subjectively evaluate the variant of testing barefoot as the simplest. There is more frequent occurence of flat foot among classic runners in comparison with minimalists. Flat foot increases risk of formation injuries, on the contrary, regular compensation motion activity decreases this risk.
