Comparison of specialized actigraphs with wearable devices in quantitative sleep analysis
Čech, Vladimír ; Zvončák, Vojtěch (referee) ; Mikulec, Marek (advisor)
Actigraphy and smart wearable devices provide similar functionality in quantitative sleep analysis. This work aims to verify how common wearable devices stand in comparison with a specialized actigraph used in clinical practice. The actigraph used in this work was Geneactiv Original and it was used to compare the sleep analysis results of eleven commercially available devices. The measurements for nine of the measured devices lasted for one week. Two devices were measured for six days. During sleep, the device was worn on the same hand as the actigraph, and at the same time a sleep diary was kept, in which data on the time of lying down, the time of awakening and the number of awakenings per night were recorded. After a week of measurement, the data obtained from the actigraph were evaluated by software and then compared with the data provided by the second device. In this work, data of total sleep time, sleep onset latency, number of awakenings during the night and sleep efficiency are compared. Ten of the eleven devices measured higher total sleep time and higher sleep efficiency than the actigraph. These devices measured higher total sleep time by 1.21 % – 12.06 % and measured higher sleep efficiency by 2.86 % - 13.86 %. One device, namely Fossil Sport, measured lower total sleep time by 9.02 % and lower sleep efficiency by 9.13 %. Sleep onset latency was the most distinct parameter. Wearable devices measured higher sleep time by 86.72 % – 1225.95 %. Neither device nor actigraph could reliably determine the number of awakenings during the night unless it was a significant physical activity during the night. From the results of the work, it is not possible to say in general that all commercially available devices would be a reliable substitute for actigraphy.

Insight to European Physiotherapy Education systems: How choice of Alma Mater affect Quality of Life and Quality of Education of Physiotherapy Students
Schramlová, Michaela ; Řasová, Kamila (advisor) ; Špaňhelová, Šárka (referee)
Objective: The objective of this study is to describe and compare the current educational systems and selective modalities related to mental health, sleep quality, nutritional habits a physical activity of physiotherapy students in Europe. Methodology: A cross-sectional, descriptive study processing two questionnaires is used with one dedicated to university representatives and the other to physiotherapy students. Results: Although 75% of students rated their quality of life positively and 47% were satisfied with their mental health, 65% showed higher levels of stress and 50.5% describe dan impaired sleep quality. The minimum physical activity of 150 minutes weekly was described by 78.9% of students, within which 67% engage in strengthening twice a week. Students with a higher stress load/worse psychological health also showed worse sleep quality and lower amount of physical activity, women were significantly worse off. In terms of physical activity and sleep quality, students from Finland and Kosovo achieved the best results, while students from Italy, Greece, and Portugal achieved the worst. Students from Italy indicated the greatest dissatisfaction with the organization of the study system and communication between teachers and have the lowest number of taught techniques (15/33), while in Kosovo...

Smart Home: Learning of Routines
Junák, Petr ; Bažout, David (referee) ; Materna, Zdeněk (advisor)
This thesis focuses on the design, development, and implementation of an innovative smart system that uses user sleep data and machine learning for intelligent control of lights in a household. The main goal is to improve the user’s sleep quality through the optimization of light exposure, particularly by reducing exposure to cool daylight before sleep. The work is characterized by an emphasis on the use of readily available data, cost-effective hardware devices, and open-source technologies. The primary source of data was the FitBit Charge 5 smartwatch, which provides detailed information about the user’s sleep patterns. The created machine learning model, specifically linear regression, is hosted on the Raspberry Pi platform, which also serves as the central unit for controlling lights and managing the overall system. In addition to light control, the system also supports sending notifications to the user about the approaching recommended sleep start time contributing to the overall improvement of sleep hygiene and sleep quality.

Ergonomie spánku u vertebrogenních onemocnění
KRBEČEK, Adam
The bachelor thesis deals with the issue of sleep quality in people suffering from back pain and examines what factors can affect sleep quality, including how posture adjustment, quality of movement stereotypes, environmental ergonomics, and sleep position can affect sleep quality. The bachelor thesis is divided into two parts, theoretical and practical. The theoretical part is further divided into three areas. The first area is sleep, which discusses what sleep is, why we sleep, and what factors can affect our sleep. Another area is the back pain itself. Including the basic anatomy of the back, the etiopathogenesis of the back pain, and finally the role of posture and the quality of movement stereotypes in connection with this issue. The third and final area is sleep ergonomics, which includes the definition and division of ergonomics, sleeping space ergonomics, and sleep positions. The practical part took place in the form of qualitative research. The study sample consisted of three probands suffering from back pain and problems with poor sleep quality. The research included input and output kinesiological analysis, interview and ergonomic analysis. Each subject underwent an 8-week therapy aimed primarily at correcting posture. During the therapy, sleep quality data were collected from a smartwatch and a sleep diary. The collected results confirm the improvement in some measured parameters of sleep quality.

The quality of sleep of SK Dynamo České Budejovice players
KALOUSEK, Marek
The main topic of this bachelor thesis was Sleepquality in players of SK Dynamo České Budějovice. The aim of this thesis was to map the quality of sleep in players and also their subjective opinion about their sleep. The secondary aim was to find out which circadian preferences prevail. Two questionnaires were used, namely the Pittsburgh SleepQuality Index (Buysse, 1989) and the Morning and Evening Type Questionnaire (Horne & Östberg, 1976) . The theoretical part of the thesis is focused on the description of sleep, sleep stages: falling asleep, waking up, sleep quality, sleep hygiene, sleep disorders and also on the club SK Dynamo České Budějovice itself and on circadian rhythms and chronotypes in sport. The respondents were professional football players of SK Dynamo České Budějovice. The Pittsburgh SleepQuality Index and the Morning and Evening Types Questionnaire were distributed and completed in person at the SK Dynamo České Budějovice buildings in České Budějovice. The results show that the players have good sleep quality and none of them have major sleep problems and do not need to take any sleep medication. The second questionnaire showed that the players tend to be of an undifferentiated type, i.e. that neither the morning nor the evening type predominates in the team of SK Dynamo České Budějovice.

The Effect of Excessive Use of Modern Technologies on the Origin of Sleep Disorders in Children of Older School Age
SOUČKOVÁ, Klára
This bachelor thesis deals with the excessive use of modern technologies for the possible origin of sleep disorders in children of older school age. The theoretical part characterises older school age, sleep, sleep disorders, the specifics of sleep in children and adolescents, modern technologies and their impact on human organism and summarises available research related to the impact of using modern technologies on the sleep quality in children. The practical part presents quantitative research examining the influence of excessive use of modern technologies on the possible origin of sleep disorders in children of older school age.
