Title: Nutrition monitoring in top Czech Republic women white water slalom athletes in the race period of the season. Aim of the study: Comparison of actual quantitative and qualitative composition of the diet in the Czech water slalom paddlers (women) in the racing period to daily recommended standards for the population group of athletes with a corresponding energy output. Using the results, create both general and individual recommendations and assess the need for the use of supplements in the diet of water slalom athletes. Methods: The thesis is a case study and it is a kind of qualitative research. For our study we chose two main methods. Prospective study method and the method of interview. To determine the total daily energy intake and diet quality inventorial analysis of the four- day dietary record of the respondents was used. For comparison with the standards, the data were subsequently processed by standardized software applications of database functions MS Excel (Vilikus a kol., 2002) and accompanied by a critical commentary. To survey the data concerning use of food supplements has been used a method in which athletes respond to questions asked. The data were assessed in writing and graphically. Results: Our study shows and critically comment on the differences between recommended and...

Dietary supplements in sport nutrition
BOČAN, David
Thesis deals with dietary supplements and their use by amateurs and professionals.The theoretical part is in the 1st part devoted to supplements and their legislation,forms and division.To the 2nd part was selected substances used by athletes and further discussed in terms of their function and effects on the organism.Within the general information was drafted in the 3rd part risks related to the use of dietary supplements due to wrong dosage or concentration and the issue of doping. Research was conducted through a questionnaire survey among professionals and amateurs.Questionnaire was created on the server google.cz and distributed in electronically and printed form.Respondents were south in several ways.There were used personal contacts and sending questionnaires to sport clubs.Research group contained 166 respondents-83 amateurs and 83 professionals.For evaluation were used basic statistical tests-pivot tables and chi-square test.The processing of results was made in Microsoft Excel 2013. Besides aims to map the use of supplements by athletes were expressed two hypotheses. The 1st hypothesis: There are statistically significant differences in knowledge of supplements between amateur and professional athletes.The 2nd hypothesis:There are statistically significant differences in the use of supplements between amateur and professional athletes. The 1st hypothesis was rejected.There were no statistically significant differences in knowledge of supplements between amateurs and professionals.The 2nd hypothesis was dealt separately for four seasonsfor the period of preparation before exercise/after exercise and for the period of the season, again before exercise/after exercise.In periods of preparation (before and after exercise) and after exercise in the season, there were statistically significant differences in the use of supplements between amateurs and professionals. In these cases 2nd hypothesis was confirmed.In the period of seasonbefore exercise was hypothesis rejected. In this period was no statistically significant differences in the use of supplements between amateurs and professionals. In the next question they were asked about learning about supplements.Most of the information were received from teammate/colleague. In the next part were surveyed effects of various factors for the purchase of supplements on a scale of 0 points (least)-10 points (most influence). Price is a factor that rather affects athletes but more the group of amateurs.Quality has a great influence on both groups. The country of origin is a factor which has by amateurs the largest representation at the point 0. Professionals find it like rather affecting. Brand name is a factor in both groups rather affecting. The package (label) doesn't rather affects athletes,more on amateurs. Recommendations known and previous experience are important for both groups of athletes.The influence of habit is not clear, almost all points are represented by the same ratio of votes. Discount and advertising are factors that affect athletes rather not.Influence expert forums and reviews on amateurs is not clear, professionals voted the most mean value. The most common reasons for using supplements are for both groups regeneration, energy source,adding vitamins and joint nutrition.Amateurs monthly invest in the purchase of dietary supplements less (500 CZK),professionals 500 or 1000 CZK. The most preferred forms of supplements are tablets,powders,capsules and liquids,including beverages.Sticks and gels are used more by professionals. Most of respondents use supplements by recommendation exactly or rather. The most common place of purchase supplements are for professionals specialized stores and for both groups also the Internet. Thesis could serve as an information resource for athletes to clarify that dietary supplements should take depending on what they want to achieve.Also it could be used as study material for courses dealing with nutrition and sport.

Selective isolation of the genus Bifidobacterium bacteria from foods
Mizerovská, Lucie ; Šárka, Havlíková (referee) ; Rittich, Bohuslav (advisor)
Probiotic lactic acid bacteria (LAB) are very often used in food procesing industry, such as milk products, cheese and fermentsd salami production in nova days. In diploma thesis were tested symbiotic food supplements from different producers. Bacterial DNA was isolated from crude cell lysates of six food suplements by magnetic particles P(HEMA-co-GMA). PCR-ready DNAs were isolated. from all products The detection of Bifidobacterium bacteria identified by PCR was in agreement with those declared by the manufacturers. Magnetic particles with immobilized antibodies against Bifidobacterium were used in the next part of thesis. These particles were used for the isolation of target cells from two products with cell identification by genus specific PCR.

Development of probiotic dietary supplement
Krahulcová, Aneta ; Vítová, Eva (referee) ; Vránová, Dana (advisor)
The thesis deals with a theme of probiotic mikroorganisms which are aplicated as a dietary supplement. Health benefit on the host have been known for a long time, however, there might be some negative effects affecting a consumer. In connection with this observation defining requirements and evaluating of safety of probiotics in food was necessary. The new probiotic dietary supplement can not be expanded on the market without these processes. Every strain must be tested separately on each property. The ability of rezistance against conditions inside human gastrointestinal tract belongs to the most basic tests. The aim of the practical part is testing this ability of rezistance in vitro by simulated conditions. The model of gastrointestinal juices was designed according to the Czechoslovak codex. The form contributes to the higher rezistance of probiotics within implementing to the host. Also a dosage form of probiotics was involved to a in vitro testing.

Dietary supplements with adaptogenic effects
Izraelová, Alexandra ; Vespalcová, Milena (referee) ; Souralová Popelková, Miriam (advisor)
The aim of this thesis was to design a recipe for the dietary supplements with adaptogenic effects, production, and subsequent analysis (proteins, lipids, carbohydrates), which led to the determination of the energetic value of preparation. Adaptogenic effects are the domain of plants and fungi, known as adaptogens. Adaptogens act non-specifically to the human body - improve the overall condition of the body, accelerate healing and regenerative processes, slow degenerative processes in the body and thus the aging process. As biogenic active stimulators, they affect not only in the physical but also in mental area. Dietary supplements have been designed in three different forms - capsules, syrup, drops. The analysis was also performed in tablets of Vietnamese origin supplied by supervizor, of which entry to our market is being considered. Protein content was determined by Kjeldahl method, lipids by Soxhlet extraction, saccharides by gravimetric method. Dietary supplements were analyzed for heavy metals (Pb, Cd, Hg), and in herbal drops ethanol content was determined.
