Linhartová, Gabriela ; Chrástková, Martina (advisor) ; Polášková, Marcela (referee)
Title: The nutrition in bodybuilding and fitness Purposes: The aim of the Bachelor thesis was to reveal differences in nutrition of active competitors in bodybuilding and fitness versus recommendations of publicly available scientific literature about nutrient intake, use of dietary supplements and adherence to drinking in the bulk, cutting and final period of super-compensation. Methods: For the research, the qualitative method was chosen as a survey. The questionnaire is divided into questions about the different periods of preparation for the competition in bodybuilding and fitness. It contains a combination of open and closed questions. The selected set of examinations was a random sample of competitors in different categories of bodybuilding and fitness. Results: In the survey, it was found that competirors usually eat according to recommendations made available to the public. However, individual differences were also found in nutrition intake, drinking, use of dietary supplements in the bulk and cutting period. Were found the specific procedures in nutrition intake, drinking, use of dietary supplements and sweeteners in the period of super-compensation. Key words: Nutrition, competition preparation, competitor, bodybuilding, dietary supplements

Vitamin preparations during pregnancy
Matoušková, Karolína ; Ježková, Jana (advisor) ; Vítková, Hana (referee)
This thesis discusses problems of pregnancy and increased nutrient requirements with a focus on vitamins and minerals. It is divided into two parts - theoretical and practical. The aim is to identify those vitamins and minerals that may be deficient during pregnancy and thus their intake should be increased. The theoretical part describes the importance of particular elements for the specifics of pregnancy and possible symptoms of deficiency or excess, with the pregnancy orientation. The practical part focuses on the evaluation of selected multivitamin and multi mineral supplements which are intended for pregnant women. The main criterion is to ensure sufficient amounts of vitamins and minerals during the increased demands of pregnancy. Evaluation is done by comparing two parameters - the recommended daily dose for pregnant women and the amount of micronutrients contained in the composition of given products. Content analysis was used as the data collection technique for the basic quantitative research. Finally, it discusses the usefulness of the administration of vitamin supplements during pregnancy, and whether a balanced diet is sufficient enough to meet the needs of the organism even in states where there may be some lack of vitamins and minerals. Key words: pregnancy ; nutrition ; vitamins ;...

UV-photochemical generation of volatile selenium compounds for ultratrace analysis by AAS
Rybínová, Marcela ; Rychlovský, Petr (advisor) ; Komárek, Josef (referee) ; Šíma, Jan (referee)
This thesis deals with the study of UV-photochemical generation of volatile compounds (UV-PVG) in connection with atomic absorption spectrometry (AAS). Selenium (Se(IV)) was selected as a model analyte and many experiments were carried out to expand the current sum of knowledge of the topic. The study was commenced by assembling the UV-PVG apparatus in the continuous flow mode. The detection method used was AAS with externally heated quartz furnace atomizer. The focus of the first step of the study was on the construction of the volatile compounds generator (UV-photoreactor) with emphasis on the material used; tubes made of teflon or quartz of different diameters were tested. The construction of the apparatus was followed by optimization of the reaction conditions (the type and concentration of the photochemical agent and other agents, which increase the analytical signal; the carrier gas and the auxiliary hydrogen gas flow rate; the sample flow rate). Eventually, the analytical figures of merit of the selenium determination using the proposed method were found. The results showed that teflon reaction tubes are a good competitor to those made of quartz. The accuracy of the method has been successfully verified by analysis of certified reference material and its applicability has been further tested...
