Electromyography, measurement of muscle electric activity
Kořínek, Peter ; Provazník, Ivo (referee) ; Kolářová, Jana (advisor)
The task of this thesis was to become acquainted with the issue of measuring of muscle electric activity.In the theoretical part we became familiar with the computer measuringsystem BIOPAC and its options to measure monitored magnitudes. This continue with practical part, in which we watch the problematic according to a theory in a group of people. We learned data with BIOPAC according to protocol of the result of physicaleffort influence on EMG. In the end the results were statistically analysed. The data as a product offallowing research were verified by hypothesis. In thelast step, the data are presented in graphical user interface development environment. After loading of the EMG of measured person, the process are displayed-without, with and after the power with onus. It is possible to choose from different analyses.
The influence of thyroid hormones and adrenal glands on mental function
Augustinová, Jana ; Šivicová, Gabriela (advisor) ; Špinka, Marek (referee)
This thesis focuses on effects of thyroid and adrenal hormones on mental functions, especially on cognitive functions and emotions. In the case of adrenal hormones it will also focus on stress and burnout syndrome, which are not considered as mental functions, but are connected to both psyche and the above mentioned hormones. The text is divided into two parts. The first, theoretical part deals with the anatomy and histology of these two organs, hormones that they produce and their influence on overall physical condition and pathology. The main section of this theoretical part deals with the description of influence of thyroid hormones and adrenal glands on the above mentioned mental functions. This work is based on both earlier and contemporary research, but predominantly on foreign research. In the second, empirical part, a proposal for longitudinal study of cortisol and thyroxine levels during depression treatment is presented. Klíčová slova: Hormones, thyroid glang, adrenal gland, mental functions, cognitive functions, emotions, stress, cortisol, thyroxine
Regular physical activity as a circadian Zeitgeber
Fenclová, Aneta ; Bendová, Zdeňka (advisor) ; Červená, Kateřina (referee)
The function of almost every cell in the body is regulated by the circadian system. At the whole-body level, this system consists of the main oscillator, which is formed by the suprachiasmatic nucleus of the hypothalamus, and peripheral oscillators of individual organs and tissues. This system is sensitive to periodic changes in the external environment, particularly to the alternation of light and darkness, and under unfavorable lighting conditions, it can lead to desynchronization of both this timing system with the solar cycle and the mutual desynchronization of individual organs and tissues. This temporal mismatch of physiological processes can cause a range of diseases and metabolic disorders, and can be partially prevented by regular physical activity. Daily oscillations of circadian rhythms in many cardiovascular and metabolic parameters also determine the ideal time of day for anaerobic performance. This bachelor's thesis is a selection and comparison of information from professional literature and available studies dealing with the mutual influence of physical activity and circadian rhythms. There are works mentioned here that test the effect of physical activity on internal desynchronization of the melatonin rhythm and sleep pattern, on the circadian synchronization of skeletal muscle, as...
The Importance of Circadian Rhythms in Humans with a Focus on Adolescents
Kolářová, Michaela ; Vančata, Václav (advisor) ; Ehler, Edvard (referee)
The aim of the presented diploma thesis is a detailed outline of the meaning of circadian rhythms in adolescence. Circadian rhythms appear in early childhood, but undergo many changes during lifetime. While in early childhood the waking and sleeping cycle shifts to an earlier time, during adolescence it is quite the opposite and the cycle is shifted a few hours later and in older age the cycle even returns to an earlier state. Adolescence is associated with the most significant changes and increased demands on study, independence and generally more overload at the expense of quality and adeqaute sleep, which not only causes circadian rhythms to dissipate and shift dramatically, which such as health. For adolescents, the delayed phase is naturally correlated with sexual development, with sleep patterns being controlled by the biological component. Respecting physiological changes in adolescence and striving for institutional changes seem to be the most appropriate therapies instead of forcing patterns basen on institutional and parental needs, which only undermines adolescent body chemistry, results in insufficient and poor quality sleep for functioning and healthy physiological development of adolescents.
Způsoby hodnocení stresu u koní
ČERNÁ, Michaela
This bachelor's thesis deals with the currently highly addressed issues in horse bree-ding, which is stress. It can be caused by a number of causes and lead to a number of undesirable consequences. These can adversely affect the health, performance or behavior of the animals. Therefore, this is a very important topic for horse breeders. The aim of this bachelor thesis was to write available current information about horse stress and select appropriate methods for its evaluation. The following proce-dures were chosen: heart rate, cortisol levels, body temperature and eye temperatu-re. The observation included 3 individuals who were integrated into the new herd. The most effective way to evaluate the degree of tremor in the incorporation of horses into a new herd was to measure the temperature of the eye using a thermal camera. Within 3 days, the value of the eye temperature dropped from 35.5 °C to 31.6 °C. An invasive and accurate method for determining stress in horses was found-free determination of blood cortisol concentrations, which were recorded at 64.3 nmol / l, 29.7 nmol / l when collected at 17:00 and 149 nmol / l when collected at 10:00. The morning time proved to be more suitable for blood collection to assess the degree of stress. Heart rate was recorded as normal (36 bpm, 44 bpm) and did not reflect the stress response. Rectal temperature measurement has proven difficult to perform in horses in a new environment and under stress. Eye temperature measurement proved to be the most accurate method for asses-sing stress in horses and blood cortisol levels, which is more suitable for scientific purposes. However, the goal of every breeder should be to try to prevent stressful situations, especially by fulfilling the welafre in horse breeding.

How doe's playing MMORPG influence mood of players
Kůra, Michal ; Lukavská, Kateřina (advisor) ; Hrabec, Ondřej (referee)
This bachelor thesis examines how doe's playing MMORPG game influences mood of the player. The main goal of research is to experimentaly verify if there is some mood boost caused by playing MMORPG game. This possible effect is examined via the BMIS questionnaire, which measures actual emotional state of player. BMIS questionnaires were administrated right before and after activity, to find out the difference caused by the activity. According to findings of this experiment playing MMORPG game significantly improves the mood, in comparison with watching documentary film. Some additional measures support the theory, that mood improvement during the game could be linked with development of the flow experience, which has, as some previous studies found out, higher probability to develop during playing MMORPG game then during other non-virtual leisure time activity such as watching documentary film.
Beneficial Effects of 11β-HSD1 Inhibition on Cognitive Performance in a Mouse Model of Alzheimer's Disease
Červinková, Tereza ; Červený, Lukáš (advisor) ; Musílek, Kamil (referee)
Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmacology & Toxicology Candidate: Tereza Červinková Supervisor: PharmDr. Lukáš Červený, Ph.D. Title: Beneficial Effects of 11β-HSD1 Inhibition on Cognitive Performance in a Mouse Model of Alzheimer's Disease The increased life expectancy goes hand in hand with ageing-related cognitive impairments. Alzheimer's disease (AD) is the most common type of dementia being an irreversible and progressive brain disorder with loss of cognitive functions. Recent studies suggest that excess of glucocorticoid (GC) action exerts deleterious effects on the hippocampus and causes impaired spatialmemory. In addition, it has been demonstrated that aged mice with cognitive deficits show increased gene expression of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) in the hippocampus and parietal cortex. The Senescence-Accelerated Mouse Prone 8 (SAMP8) strain is a spontaneous animal model of accelerated ageing. Many studies indicate that SAMP8 harbour the behavioural and histopathological signatures of AD. In the present study, we evaluated the neuroprotective effects of 11β-HSD1 inhibition by a potent pyrrolidine-based compound RL-118 and/or effects of diet on cognitive performance in different groups of SAMP8 by conducting behavioural and...
