Nutrition and supplementation in fitness and bodybuilding
Havlová, Ivona ; Kimmer, David (advisor) ; Šimková, Simona (referee)
Nutrition and Supplementation in Fitness and Bodybuilding Abstract The topic of this master's thesis is "Nutrition and Supplementation in Fitness and Bodybuilding". Physical fitness is getting more and more popular and becoming a global industry. Young people tend to prefer gyms to other types of physical activities. The advantage of fitness workouts is that there is no age limit, provided the person is healthy, as evidenced by exercising individuals who are 15 years old but also senior citizens over the age of 65. The empirical part of the paper was conducted using a qualitative method, gathering respondents through snowball sampling where participants identify others. As many as 28 respondents were divided into two groups: people doing conditioning and bodybuilding whose characteristics are explained in the Operationalisation chapter. All respondents did a semi-structured interview and provided a three-day diet plan. The goal was to map eating habits and the most common diet plans of people doing conditioning and bodybuilding, and to discover supplements they use the most frequently. The practical part of the thesis focused on the most frequent diet plans and supplements in fitness practitioners. The research findings indicate that the most common diet is high in protein and carbohydrates and low in fat,...

Primární prevence u adolescentů z pohledu stravování
KIMMER, David
Aims: The aim of the dissertation was to conduct a survey on eating habits and consumption of selected nutrients in adolescents, depending on the sex and the type of the school attended. Another objective was to check the influence of mass media and an educational program on the formation of eating habits. Based on all the findings, an education plan focused on eating habits was created for the needs of nurses to educate adolescents. Methodology: For the purposes of dissertation research, a combination of quantitative and qualitative research was used. The quantitative part of the research was realized using a combination of two questionnaire tools ? a self?constructed questionnaire measuring adolescents´ eating habits, and the Three Factor Eating Questionnaire (TFEQ). A total of 1130 15?18 year-old students of four?year grammar schools, secondary medical schools, and students of the specialization chef?waiter at vocational schools from the South Bohemian Region were involved in the study. The qualitative research was based on a comparative analysis. A total of 59 probands from the three types of schools above mentioned were selected. Results: The results of our research show that there are no statistically significant differences in compliance with nutrition recommendations regarding gender, but significant differences were found in connection with the type of school attended, where the nutritional recommendations are mostly followed by students of grammar schools, then by students of secondary medical schools and in the smallest degree by students of secondary vocational schools ? the chef ?waiter specialization. Significant differences between sexes were found in consumption of selected food components, when girls compared to boys eat more fresh vegetables and fruits. On the contrary, boys eat more beef, pork and poultry meat, sausages, potatoes, eggs and fried foods compared to girls. There were also significant differences between students of particular types of schools. There was no statistically significant relationship between mass media influences on eating and adolescents' nutritional recommendations. Based on the TFEQ results, it can be concluded that there is a statistically significant difference in the conscious reduction of food intake by gender where girls cut down on food intake more than boys. The results of the qualitative part of the research show that an appropriately chosen educational program has an influence on the formation of eating habits in adolescents. Scientific benefits of the dissertation: The benefit of this research is, above all, the fact that as one of the few studies that have been done, this one brings comprehensive information about nutrition of adolescents aged 15?18 WHO study at grammar schools, secondary medical schools, or study the specialization chef-waiter at vocational schools. The results of our research are in many respects consistent with those obtained by other researchers and refer to the fact that adolescent eating habits cannot be described as ideal. In view of our findings, it would be useful to carry out other research surveys concerned with dietary habits and eating behaviours in a representative research sample of adolescents within the Czech Republic.

Microfltration nanofibrous membrane for wastewater treatment
Lev, J. ; Holba, Marek ; Došek, M. ; Kalhotka, L. ; Detvanová, L. ; Dostálová, L. ; Přichystalová, J. ; Vincent, I. ; Kimmer, D.
Pilot testing of nanofiber membrane module demonstrated long-term stability of the filtration process in activated sludge and showed the applicability in real-world conditions at the wastewater treatment plant. Microbial contamination of samples of the filtrate reached log removal 2 CFU/mL. Filtration in combination with UV irradiation resulted in a reduction of microbial contamination under required legislative standards. These results supported our assumptions to use nanofibre membranes in membrane bioreactor. Regeneration, optimization and antifouling surface treatment will be another step to increase the competitiveness of nanofiber membranes for water treatment.

Bacteria deactivation and removal from Wastewater and polluted Air
Kimmer, D. ; Vincent, I. ; Dudák, J. ; Bergerová, E. ; Petras, D. ; Lev, J. ; Holba, Marek ; Kalhotka, L. ; Mikula, Přemysl ; Kořínková, R. ; Kubáč, L.
Procedures permitting to prepare homogeneous functionalized nanofibre structures based on polyurethanes modified by phthalocyanines (PCs) by employing a suitable combination of variables during the electrospinning process are presented. Compared are filtration and bacteria deactivation properties of nanostructures without PCs, modified in bulk and with PCs embedded into polyurethane chain by a covalent bond protecting the release of active organic compound during the filtration process. Finding that the functionalized nanofibre structures have an effect on bacterial growth was confirmed by microbiological, physico-chemical and molecular biological analyses, such as the inoculation in a nutrient agar culture medium, flow cytometry and real-time polymerase chain reaction.

Experimental Study on Bacteria Removal from Artificial and Real Wastewater by Nanofibrous Filters
Lev, J. ; Holba, Marek ; Kalhotka, L. ; Mikula, Přemysl ; Kimmer, D.
Unique properties of electrospun nanofibrous materials could be utilized in various environmental technologies, e.g. bacteria removal from water. Recent studies show various removal efficiencies of bacteria and particulated matter by nanofibrous filters. Our article presents results from filtration tests through polyurethane nanofibrous material on short-term scale with artificial wastewater and also results from tests with real wastewater. We determined E. coli abundances in artificial and real wastewaters and the amount of the other hygienically important bacteria in real wastewater samples only. The results show possibility of long-term full-scale application of those materials, however some material modifications are needed to be accomplished.

Can Nanofibers Replace Current Microfiltration Materials?
Lev, J. ; Holba, Marek ; Došek, M. ; Kalhotka, L. ; Kimmer, D.
The electrospun nanofibrous material M247 can be used as antimicrobial filter. Laboratory tests show high removal value (up to 6 log10 CFU/mL) and similar filtration efficiency compared filter Pragopor 6, presently used for sterilization of liquids in laboratories. Semi-pilot test confirmed good mechanical endurance and high removal efficiency. Our study showed high removal value with non-functionalized nanofibrous material despite of other cited studies. These results confirm our expectations, that nanofibrous material can replace the current filtration materials for laboratory use.

Effect of Morphology of Nanostructures to Filter Ultrafine Particles
Kimmer, D. ; Vincent, I. ; Fenyk, J. ; Petráš, D. ; Zatloukal, M. ; Sambaer, W. ; Ždímal, Vladimír
Selected procedures permitting to prepare homogeneous nanofibre structures of the desired morphology by employing a suitable combination of variables during the electrospinning process are presented. A comparison (at the same pressure drop) was made of filtration capabilities of planar polyurethane nanostructures formed exclusively by nanofibres and space nanostructures having bead spacers or structures formed by a combination of micro-and nanofibres, through which ultrafine particles of ammonium sulphate 20 - 400 nm in size were filtered. The structures studied were described using a new digital image analysis technique based on black and white images obtained by scanning electron microscopy.

Difference Between the Lifestyle of Men and Women - Students of South Bohemia University
KIMMER, David
Lifestyle is one of the most important factors that can affect health but in these days lifestyle of many people is alarming. Scientists agree that more than 60 % of diseases are caused by a wrong lifestyle. My essay is divided into theoretical and empirical part. In the theoretical one I deal with the definition of a lifestyle and factors that can affect it (nutrition, sport, drug addiction, relaxation, sex, sleep). In the empirical part I present results of my investigation which was focused on the difference between the lifestyle of men and women ? students of USB. I used qestionnaire with 33 questions given to 420 respondents, rate of return was 87 %. I think that this essay can be very well used in nutrition ambulance, teachwares and also in public who is not negligent to their lifestyle.

Using of flow cytometry for the detection of bacterial filtration efficiency in (waste)water treatment processes
Mikula, Přemysl ; Lev, J. ; Kalhotka, L. ; Holba, Marek ; Kimmer, D. ; Maršálek, Blahoslav ; Vítězová, M.
Aim of the study was to detect filtration efficiency of several (nano)materials used for the filtration/removal of E. coli bacteria or natural bacterial communities from water samples. Filtration efficiency was evaluated by commonly used culticvation techniques as well as by flow cytometry (FCM). Although filtration efficiency of certain nanomaterials detected by cultivation was very high (>99%), it was demonstarted that sample filtration does not have to lead to significant decline of total bacterial counts measured by FCM. From this viewpoint FCM can be considered as a suitable analytical method for the assessment of wastewater treatment processess efficiency, which, compared to cultivation techniques, possess some disadvantages (difficult standardization) but also has several advantages (speed, more realistic measurement conditions).
