Lauberová, Michaela ; Majorová, Simona (advisor) ; Nováková, Pavlína (referee)
Title of the bachelor thesis: The use of regeneration in the recreational sports population Goals: To determine whether recreational athletes use regenerative means and, if so, which specific means are used. To identify the reasons that influence the selection of regenerative means. Metohods: The data needed for the purposes of the bachelor's thesis were collected through a non-invasive online surfy, the quantitative research method was used in the work. The type of research is theoretical-empirical. The online surfy, which is completely anonymous, was posted on the social network Instagram nad Facebook, as an internet link, and was intended for recreational athletes agend 18-65. The research population is made up of the recreational athletes (48 women and 13 men) took part in the research. The data was processed through graphs and tables. Results: Based on the results of the survey, it was found that 91,8 % of recreational athletes use some of the regenerative means (massage, compensatory exercises, and regenerative procedures). According to the subjective perspective, 41 % of respondents reported following a healthy diet. The most frequent reason given by respondents (26,2 %) for using regenerative means was relaxation, and the second most frequent reason (24,6 %) was regeneration. When selecting...

The effect of exposure to a preferred odour on mental sleep activity and its characteristics and affective state upon waking
Jankovská, Tereza ; Martinec Nováková, Lenka (advisor) ; Sebalo Vňuková, Martina (referee)
Tereza Jankovská Abstract Previous literature shows that preferred odours serve as powerful cues for information retrieval from autobiographic memory and that exposure to odours during sleep affects the emotional tone of dreams. In the present study, we sought to investigate how continuous stimulation with a preferred odour influences various dream characteristics, dream emotions, and post-sleep core affect during all-night exposure. Eighteen healthy adults were invited to visit the sleep laboratory three times in weekly intervals. The first visit served to adapt the participants to the laboratory environment. On the second visit, half of the participants were exposed to an odour they chose themselves or to the odourless control condition. On the third visit, they received control or exposure in a balanced order. On each visit, the participants were woken up from the rapid eye movement (REM) sleep stage. Dream pleasantness, emotional charge of the dream, positive and negative emotions experienced in the dream, and four dimensions of post-sleep core affect (valence, activation, pleasant activation-unpleasant deactivation, and unpleasant activation-pleasant deactivation) were assessed. Presented results are not consistent with previous studies, i.e. no statistically significant difference between the...

Effect of acute sleep deprivation in different light conditions on the quality of recovery sleep
Zeithamlová, Barbora ; Kopřivová, Jana (advisor) ; Vlček, Kamil (referee)
Sleep is regulated by homeostatic and circadian processes. The circadian process is controlled by the internal biological clock, which is regularly synchronised with the external world by so-called zeitgebers. The most important zeitgeber for humans is light, therefore incorrect timing of light signals can lead to desynchronisation of the clock and sleep disruption; however, this depends on the intensity and spectral characteristics of the light. Dimmed red light is unlikely to significantly interfere with sleep regulation, but white light with a higher intensity could. White light is typically used when people stay awake during the night and experience acute total sleep deprivation. This could potentially interfere with the compensatory mechanisms occurring during subsequent recovery sleep. We therefore decided to test whether and how different lighting conditions during sleep deprivation can affect the structure of recovery sleep. We had 12 healthy uniform volunteers undergo two acute total sleep deprivations; one under normal white light, the other under dim red light. Using polysomnography, we measured the sleep parameters of both recovery sleeps and compared them. It turned out that sleep that occurred after the sleep deprivation in constant dim light conditions was less fragmented, had...

The effect of sleep on muscle hypertrophy
Toušková, Barbora ; Skálová, Kateřina (advisor) ; Kolář, David (referee)
Sleep represents one of the fundamental aspects of human life and health, influencing many physiological functions including muscle hypertrophy. Sleep is regulated by various external and internal stimuli, such as the circadian rhythm, body temperature, gene expression, and the synthesis of hormones and neurotransmitters such as melatonin and adenosine. Muscle hypertrophy is a complex process of enlarging muscle fibers, which is associated with numerous metabolic processes and signaling pathways, including the IGF-1-PI3K-Akt- mTOR axis, and is regulated by hormones such as testosterone, GH, myostatin, and activin. Most of these hypertrophic factors are closely linked to quality and sufficient duration of sleep. Sleep deprivation negatively affects almost all processes involved in muscle hypertrophy and, in the long term, leads to muscle loss instead. Key words: Sleep, circadian rhythm, melatonin, muscle hypertrophy, Akt, mTOR, sleep deprivation

The effect of sleep on the psychological functions of adolescents
Kaňková, Zuzana ; Nekovářová, Tereza (advisor) ; Blahna, Karel (referee)
The quality of sleep is one of the main factors for the homeostasis of the body, the functioning of the brain and therefore the psychological functions of the individual. Sleep undergoes various changes during life. Significant sleep changes can be observed in adolescents. During this developmental period, there is a shift in circadian preferences towards a later chronotype, which is often in conflict with the demands of functioning in everyday life (for example waking up to school). Because of that this group is highly vulnerable to chronic sleep restriction and associated sleep deprivation, which can lead to many pathologies. The aim of this study was to investigate the effect of partial sleep deprivation on cognitive function and emotional regulation in adolescents. The study involved 59 adolescents aged 14 to 21 years, 30 of them were exposed to partial sleep deprivation (4 hours/night) and 29 of them slept normally (8 ± 1 hours/night). The day after instructed sleep/sleep deprivation, participants completed an experimental battery of cognitive tests. The study found that adolescents after one night of partial sleep deprivation showed greater levels of subjective sleepiness than their peers after a night of normal sleep. This effect of sleep deprivation was stronger in girls than in boys. Also...

Sleep education in students of high school
Horáčková, Lucie ; Frombergerová, Anna (advisor) ; Švamberk Šauerová, Markéta (referee)
This thesis focuses on the effectiveness of sleep education on sleep quality and well-being in third and fourth year high school students. The implementation of sleep education was conducted between December 2023 and February 2024 in selected high schools. The research included the administration of standardized methods at two times, namely before sleep education and after sleep education. The instruments chosen for this research were the Pittsburgh Sleep Quality Index (PSQI), the Insomnia Severity Index (ISI), and the World Health Organization Well-Being Scale (WHO-5). The variables were given by the final scores from the two measurements of three scales mentioned above, which were then compared using appropriate statistical methods. At the same time, the research focused on the comparison of the given variables between the group of students who received sleep education and the group of students who did not receive any education. The thesis also focuses on opinions of students about the sleep education, its usefulness and possible suggestions for similar future programmes. The results of the study suggest that despite efforts to implement sleep education, there was no significant improvement in sleep quality among students. At the same time, the results did not show better sleep quality and...
