Kinematic analysis of children's gait
Kernerová, Helena ; Vilímek, Miloslav (advisor) ; Horák, Zdeněk (referee)
Title: Children's gait characteristics and kinematic analysis Objectives: The aim of the master thesis is to perform an analysis of the gait of children engaged in intensive sports training (floorball) and children who are not intensively engaged in sports, and to compare selected spatio-temporal, kinetic and kinematic parameters of these two groups. Methods: The work has a theoretical-empirical nature with a smaller number of probands. 3D kinematic analysis of gait was recorded with a Qualisys device and reaction forces from the pad with 7 Kistler force plates. The following parameters are monitored in the thesis: step length, step speed depending on height, range of plantar and dorsiflexion in the ankle joint, rotation of the pelvis and shoulders in the transverse plane, vertical and anterior-posterior component of reaction forces from the ground. Results: The results of the study showed that for some kinematic parameters, intensive sports training of children aged 7-13 years leads to changes in the behavior of individual analyzed parameters. This is mainly due to the fact that the tested group has more symmetrical rotation of the pelvis and shoulders in the transverse plane compared to the control group. However, the results obtained in terms of statistical probability are not sufficiently...

Deličová, Tereza ; Vilímek, Miloslav (advisor) ; Horák, Zdeněk (referee)
Title: Gait analysis of female basketball players Objectives: The main objective of this thesis is to perform gait analysis using Qualisys and Kistler systems in long time female basketball players and population that does not engage in any regular sports activity on competitive level. Selected spatiotemporal, kinematic and kinetic gait parameters are compared between measured groups. Methods: 20 female probands participated in this experimental study. Tested group consists of 10 long time female basketball players between ages of 21 and 29 (mean age of 24,5). Control group consists of 10 female probands between ages of 24 and 25 (mean age of 24,5) that do not engage in any competitive sport on regular basis. Qualisys Motion Capture system was used to gather 3D kinematic gait data. Ground reaction forces were measured by using Kistler force plates. Data was obtained by both systems at the same time. Evaluated gait parameters were walking speed, step length, pelvic and shoulder rotation range of motion in transversal plane, CG of foot range of motion and all ground reaction forces components. Two-sample t-test and Mann-Whitney U test with significance level of 0,05 were used for statistical analysis of obtained data. Results: Results of this study demonstrate that long time engagement in...

Proposal for a Regulation on Markets in Crypto-Assets: Impact on Currently Available Stablecoins
Vilímek, Matyáš ; Sejkora, Tomáš (advisor) ; Kotáb, Petr (referee)
1 Proposal for a Regulation on Markets in Crypto- Assets: Impact on Currently Available Stablecoins Abstract On 24 September 2020, the European Commission introduced its Proposal for a Regulation on Markets in Crypto-Assets (MiCA). In addition to regulating general crypto-assets, so-called crypto-asset service providers, and market abuse in relation to crypto-assets, MiCA also lays down rules for stablecoins, i.e., crypto-assets which aim to maintain a stable value. This thesis analyses how MiCA, if passed into law as introduced by the Commission, would impact the stablecoin market as it exists today, and how this would affect the ways people already use stablecoins. It does so by asking and answering these questions: How do different types of stablecoins function? If MiCA were applied to these stablecoins, would they be compliant? If not, which rules would they not comply with? If the rules were not changed, could we realistically expect such stablecoins to adapt? If they would not adapt and would cease to function, how would it change the way people currently use stablecoins? In its core, the thesis selects five stablecoins to represent the broader stablecoin market and then describes how they function. These stablecoins are Tether (USDT), TerraUSD (UST), Magic Internet Money (MIM), Fei USD (FEI), and...

Strejcová, Hana ; Vilímek, Miloslav (advisor) ; Goldmann, Tomáš (referee)
Title: EMGs of Back Muscles in Relation with Different Settings of the Straps of Backpacks Objectives: The aim of this study is to compare the electrical activity of chosen muscles during the gait with student backpack and during the different types of placing the backpack on the back in the vertical plane. The second aim is to find what it the best type of the backpack placement on the back based on the electrical activity. Methods: This thesis is an analytical-experimental research. In the theoretical part, there is a review of available sources relating to existing studies about load carriage, especially backpack carrying. It is preferentially about school type of backpaks, the recommended load limit, the way of placing a backpack on the back and the way of placing a load in the backpack. In the experimental part, there are methods used during experiment. The surface electromyografy was chosen as a experimental method. M. trapezius pars descendens, m. erector spinae and m. rectus abdomis were chosen for recording the EMG signal. The data were recorded during the gait with the backpack of 10% of proband's weight and during 3 different types of backpack placement. The upper type of placement was placed with the centre of the backpack in the level of seventh thoracic vertebra (T7), the middle type...

Human locomotion after total hip replacement
Horáková, Alena ; Vilímek, Miloslav (advisor) ; Horák, Zdeněk (referee)
Title: Human locomotion after total hip replacement Objectives: The aim of this thesis is to perform a gait analysis of patients after total hip replacement and to find out, how chosen temporo-spatial, kinetic and kinematic parameters change during the first half a year after the surgery. The deviations found in gait stereotypes of individual patients are further compared with results of international studies. Methods: The thesis is theoretical-empirical, with small number of patients. 3D kinematic gait analysis was performed by Qualisys system and ground reaction forces by two Kistler force plates. The following parameters are being monitored: length of step, stance phase duration, cadence, walking speed, lateral shift of the pelvis and trunk in standing phase, contralateral pelvic drop in standing phase of the leg, maximum range of motion of the hip joint in sagital plain, maximum of vertical and medio-lateral component of the ground reaction forces in the standing phase. Results: The highest side deviations between legs were found in 3 months after the surgery and remained until 6,5 months after the surgery. In this time period a lower value of the length of step, stance phase duration, maximum range of motion of the hip joint in sagital plain and also a higher lateral shift of the pelvis was...

Experimental investigation of human gait analysis parameters
Hrušková, Natália ; Vilímek, Miloslav (advisor) ; Goldmann, Tomáš (referee)
Title: Experimental investigation of human gait analysis parameters Objective: The main objective of diploma thesis was an experiment, that examined kinematic and dimensional parameters of human gait which was captured by several cameras and acquired data was recorded in 2D and 3D measurement. Secondary objective was to compare and statistically evaluate data acquired from measurement. The objective of analysis was to discover and describe possible regularities, patterns of human gait and other connections in investigated subjects. Methods: Comparative method was used in the thesis. The purpose of the experiment was to compare parameters measured during attempts of every subject that were conducted under different conditions (different velocity, dressed, undressed, in the environment of 2D and 3D recording) and also to compare different subjects with each other. Results: In the experiment we observed that it is possible to prove the relation between the length of a step and the velocity of gait and also the relation between the change in the body height and the velocity of human gait by three dimensional recording of gait and its analysis. This contention was confirmed in the comparison dressed and undressed subjects. The result of the experiment was, that with increasing velocity of gait is...

Muscle activity analysis during the violoncello play
Kasanová, Barbora ; Vilímek, Miloslav (advisor) ; Tlapáková, Eva (referee)
Title: Muscle activity analysis during the violoncello play Objectives: This thesis focuses on analysing and comparing specific back muscles of a bowing violoncellist. The findings can help understanding pathologic mechanisms and back pain caused by violoncello playing. It may be useful in choosing suitable preventive compensatory exercise as well and for future research. Eventually, the analysis could be applied in playing ergonomics and designing a proper seat. The thesis also aims on evaluating suitability of the chosen measuring method in this branch. Methods: The theoretical part reviews contemporary knowledge about musculoskeletal system disorders linked with violoncello playing. The practical part aims on evaluating data obtained from 3D kinematic analysis and surface EMG of specific back muscles of professional violoncello player during playing. Several conditions are assessed. Results: The experiment has shown that when playing a violoncello there is an asymmetric loading of the back muscles. Loading of specific muscles has is affected by way of bowing, string location and the seat. The experiment was done on a single proband, so these conclusions may not be generally valid. Keywords: violoncello playing, musicians, surface electromyography, 3d kinematic analysis, violoncellists' diseases,...
