Novák, Jan ; Nováková, Tereza (advisor) ; Heller, Jan (referee)
Title: Power output and selected cardiorespiratory parameters in elite athletes during the third to fourth week after COVID-19 infection Objectives: The aim of this thesis is to compare power output and selected cardiorespiratory parameters in elite athletes before and three to four weeks after COVID- 19 infection. Since the elite athletes undergo these health checks on a yearly basis, it is possible to compare the data before and immediately after the infection without difficulty. Methods: This thesis has a character of a quantitative research based on testing the outcomes with confirming or denying hypotheses. Out of the total of 64 elite athletes with the CPET data after the infection 17 athletes, fulfilling other criteria, were selected. I was provided with the data by Centrum sportovní medicíny z. s.. These values became the foundation for statistical hypotheses testing. Analysis of the data was done by means of a pair t-test in R software. Results: There were no significant differences in the majority of the spirometry parameters. Only the inspiration vital capacity was significantly higher (p = 0,004) after the COVID-19 infection in 14 athletes with 0,21±0,18 l improvement. There were significant differences in five of CPET parameters. Load in RCP was significantly lower (p = 0,011) in 13...
Specialni bezbodove prostory
Novák, Jan ; Pultr, Aleš (advisor) ; Klazar, Martin (referee)
1 This thesis concerns separation axioms in point-free topology. We introduce a notion of weak inclusion, which is a relation on a frame that is weaker than the relation ≤. Weak inclusions provide a uniform way to work with standard separation axioms such as subfitness, fitness, and regularity. Proofs using weak inclusions often bring new insight into the nature of the axioms. We focus on results related to the axiom of subfitness. We study a sublocale which is defined as the intersection of all the codense sublocales of a frame. We show that it need not be subfit. For spacial frames, it need not be spacial.
Development of vital lung capacity in children
Navrátilová, Nela ; Sedlak, Petr (advisor) ; Novák, Jan (referee)
Deficiency of physical activity can negatively affect the functional and morphological development of an individual. This bachelor thesis provides a basic overview of the anatomy of the respiratory system and the development of the lungs in the prenatal and postnatal period. It also follows up the development of lung function in children and the factors that influence this development. The parameters of the greatest informative value from the point of view of morphological and consequently also functional differentiation of the lungs are forced expiratory volume in t second, forced vital capacity and Tiffeneau-Pinelli index. These parameters of lung function are used by most studies that have evaluated the relationship between their level of development and the child's physical activity. The effect of physical activity on the development of lung function was recorded mainly in the pubertal and prepubertal periods. The health condition of the child is also limiting for the proper development of lung functions. Different values compared to healthy individuals occur, for example, in individuals with cystic fibrosis or asthma. Key words: Vital capacity of the lungs; spirometry; physical activity

Anthracological perspective on vegetation history in Roztoky u Prahy
Prach, Martin ; Novák, Jan (advisor) ; Beneš, Jaromír (referee)
This thesis researches forest history and human impact on it in prehistory and early Middle Ages by means of soil charcoal analysis, i.e. pedoanthracology. It focuses on a site called "Roztocký háj" with long-term human settlement near Roztoky u Prahy in central Bohemia. Pedoanthracology brings information about past woody vegetation that is very local and without much anthropogenic influence. On the other hand, archeoanthracology focuses on charcoal originating from archeological excavations directly from human settlements. These charcoals are therefore formed by human behaviour and provide general view on woody vegetation in wider surroundings of the site. Comparing results of these two approaches in Roztoky is allowed by long-term archeological excavations. They provided previously analyzed and partially published charcoal dataset. Newly obtained pedoanthracological dataset brings finer spatial scale, allows to find out the effect of local conditions on the charcoal spectra and also allows identification of possible purposefully selected taxa in the archeoanthracological assemblage. Another part of this work describes present-day vegetation around the soil profiles and examines it's possible continuity with the past vegetation. 4 soil profiles provided quite species-rich (17 taxa) charcoal...
Gait as a diagnostic marker for neurodegeneration
Pytlíčková, Kristýna ; Novák, Jan (advisor) ; Kotěrová, Anežka (referee)
This bachelor theis describes the relationship between gait and neurodegenerative diseases. The beginning of the work is devoted to the general definition of walking and factors that contribute to its variability. The strucutre of the walk cycle is described and what phases of the cycle look like. Subsequently, the evolutionary aspect of bipedia is outlined. The next part is devoted to the neural control of motor work. It describes which areas of the central and peripheral nervous system are involved in it and how the entire pathway from the central system, where the stimulus to motion is generated, through the nerve pathways to the periphery, where the movement is performer by the muscle unit. Then the thesis deals with individual methods used for quantification of walking. For the purposes of this work, these are divided into standardized ones that are routinely performer in a clinical setting, ie in hospital or laboratory, and real-life measurements, which are used for long-term monitoring in the patient's everyday life conditions. Standardized tests are further divided into non-invasive and invasive depending on whether or not the integrity of the individual is impaired. Practical application of these methods is described on four selected neurodegenerative diseases. Attention is focused on...
Immunological causes of female infertility
Bajerová, Kateřina ; Brynychová, Iva (advisor) ; Novák, Jan (referee)
Currently, up to 15 % of reproductive age couples struggle with infertility. Female infertility is the cause of conception issues in nearly 40 % of these cases. The origin of female infertility consists of wide range of causes and other factors. Immunological causes are certainly one of the most significant ones. In pathological conditions, defense mechanisms of female immune system can target alloantigens presented on sperm surface. Moreover, autoimmune response and antibody production can occur as well. Antibodies can target various parts of ovarian follicles and oocytes, phospholipids, nuclear antigens, enzymes etc. These antibodies can inhibit fertilization, maturation of oocytes and embryo, embryo implantation, and also recurrent miscarriages. The aim of this thesis is to summarize various causes of female infertility focusing on immunological pathologies. The thesis also describes functioning of immune mechanisms in the female reproductive tract and briefly touches on oogenesis and female hormonal cycle.
