Verification of metabolism prediction based on performed activity
Kopecký, David ; Pokorný, Jan (referee) ; Kopečková, Barbora (advisor)
Nowadays, metabolic rate or energy expenditure in general is one of the most discussed topics, especially in connection with a healthy lifestyle. Nevertheless, the metabolic rate can be used as a relatively accurate indicator of physical or thermal load as well. Usually, the value of metabolic rate is used as input into various physiological models. These models estimate the body’s thermal stress, for instance when working in a protective suit. The thesis deals not only with tabulated values of metabolic rate, but it also focuses on the accuracy of estimated metabolic rate using simple measuring devices. The Apple Watch Series 4 smartwatch, the Garmin Fenix 6 Pro Glass sports tester, and the Fitbit Inspire smart sports bracelet were used for the measurements published in the thesis. The results of the measurements show that contemporary sports testers are still inappropriate for use in healthcare or elite sports.

This thesis presents a summary of research of deposition of inhaled particles in children’s respiratory system which was mainly conducted on realistic model of children's lungs. Experimental part introduces BUT model representing airways of 5-years-old child which served for measurements of regional deposition. Bachelor's thesis furthermore sums up basic knowledge of respiratory system and points out anatomical and physiological differences between children and adults in given field. There are described basic deposition mechanisms and their impact on aerosol therapy as well.
Development of a methodology for calculating the residual stresses of a weldment in the Salome Meca software environment
Babišta, Jan ; Pokorný, Jan (referee) ; Vosynek, Petr (advisor)
The usage of welding in the process of manufacturing has become very widespread, mainly due to its low cost, versatility and the possibility of its automation. With its expansion comes higher demand for the possibilities of weld evaluation during the phase of design. Nowadays its possible to use tools based on finite element method for such evaluation. But the most commonly used tools are often very expensive. Therefore, the possibility of using Open-Source tool such as Salome-Meca to simulate the welding process as an alternative to commercial software was investigated. The first part of the work deals with the welding process and a description of the formation of residual stresses and deformations. It also deals with the description of the Salome-Meca software environment and the Code-Aster solver. In the next part the capabilities of the software in relation to problem of welding simulation are discussed. Furthermore, the goemetry of solved weldment, welding conditions, material properties and boundary conditions of the calculation are described. And finally, the individual solutions, their results and disadvantages of used approaches.
Ernst Cassirer and ethnolinguistics
Pokorný, Jan ; Vrhel, František (advisor) ; Korecká, Zuzana (referee)
Ernst Cassirer dealt the linguistic form to make his point and document the thesis of his culture philosophy. In addition to the common philosophic idealism working on the I. Kant's philosophy, first of all it was the idea of the cultural heterogenity, its purpose and common trend of its development. His ideas concerning the relation of mind and symbolic forms can be compared with the modern lines of the cognitive science, first of all connectionism and enactivism. The language according to Ernst Cassirer has got other fonction than the other cultural forms and these functions influence its form. The language according to Cassier does not present a copy of the reality but it includes a specific way of the conceptualisation for which is typical greater concretedness unlike other cultural forms. On this basis Cassirer creates evolutionary succession of linguistic phenomenons that supposes lower position of the non- European languages. Although some similar attempts can be traced nowadays, it is not possible to accept Cassirer's linguistic evolutionism or another one. The features of primitivism and forwardness cannot be generalized for any division of primitive and forward languages and the forwardness criterions used by Cassirer do not fit. Cassirer's idea of the linguistic development approximately...
EMG study: Nordic hamstring exercises vs. isometric training
Kudláček, Jiří ; Slabý, Kryštof (advisor) ; Pokorný, Jan (referee)
Bibliographical record: KUDLÁČEK, Jiří. EMG study: Nordic hamstring exercises vs. isometric training. Prague: Charles Univerzity, 2nd Faculty of Medicine, Department of Rehabilitation and Sports Medicine, 2020, 79p. Supervisor MUDr. Kryštof Slabý. Abstract This thesis is an EMG study, which examines an electric activity of knee flexors and m. quadriceps femoris during 3 types of exercises: Nordic hamstring exercise, single leg sliding leg curl, and isometric contraction. The theoretical part summarizes anatomy, physiology, and kinesiology of the musculoskeletal system, as well as the principle of surface EMG. In the experimental part, the EMG study was conducted on 20 healthy individuals aged 20 to 30 years-old. Each patient underwent an applied kinesiology procedure and subsequently went through an 16 channel surface EMG technique. The aim of this work is to compare the maximal and average value of the EMG amplitude of particular muscles during each exercise. While providing Nordic hamstring exercise and single leg slide, the light was shed on a question of whether there is a statistically significant difference between activation of m. biceps femoris and m. semitendinosus in terms of EMG values. The following phase of the thesis scrutinized the timing of hamstring muscles during Nordic hamstring...
Kinematic analysis of running in children aged 6 to 8 years
Hrachovcová, Monika ; Slabý, Kryštof (advisor) ; Pokorný, Jan (referee)
This diploma thesis deals with the biomechanics of running and the kinematic analysis of running in children aged 6 - 8 years. The paper consists of two parts. The first part deals with the biomechanics of running and its development, running injuries and describes the kinematic analysis of running. The PubMed, the ScienceDirect Database and sources of the National Medical Library and of the Charles University were searched for creating this theoretical part. The second part describes the experiment - methods and its results. 70 children were recorded during overground running at spontaneous speed. The obtained video recording was measured using the Kinovea 0.8.12. program. The video was scrolled through frames and three moments of the stance phase (initial contact, midstance and moment toe-off) were detected. At these moments selected angles in the sagittal plane were analyzed. These angles were described in the terms of descriptive statistics. Certain characteristics subdivided the cohort into two groups. These were compared in kinematic parameters to determine statistically significant differences. The obtained values from the experiment are discussed and compared with the the values from the recent literature dealing with kinematics of running. At last the suggestions for further research are...
Preventive examination of sportsmen in Czech republic and comparison of physical parameters occuring in different disciplines
Vrbík, Michal ; Slabý, Kryštof (advisor) ; Pokorný, Jan (referee)
The aim of this work is to document the content and extent of preventive checkups of sportsmen in Czech republic. The content of obligatory checkups will be examined upon its impact on preventing serious injuries of the movement apparatus as well as diseases of circulatory system and other internal systems. I am going to describe typical abnormalities of myosceletal apparatus which may increase the possibility of acquairing acute or overuse injury. Consecutinely an exemplary phenotype of a sportsmen will be presented. I chose fotball and I will describe the typicall aberrations which potentionally lead to trauma of the movements apparatus including typical injuries. The work will also contain a case report of examination of footballer. I will then compare the findings with the typical phenotype of footballist described in literature.
