Creatine and Carnitine Use in Sport
Vodičková, Věra ; Vilikus, Zdeněk (advisor) ; Boudová, Lea (referee)
5 Abstrakt Kreatin je z 95 % obsažen v kosterních svalech, kde je z 65 % fosforylován na kreatinfosfát. Denní potřeba 2 g je kryta příjmem z potravy a biosyntézou. Systém kreatin - kreatinfosfát slouží ve svalech pro rychlou regeneraci ATP, pro vyrovnávání pH a podílí se na růstu svalové hmoty. Základní a prokazatelně účinnou formou suplementů je kreatin monohydrát, jiné preparáty nejsou účinnější. Podávání kreatinu je bezpečné, potvrzeným nežádoucím účinkem je pouze nárůst hmotnosti a trávící obtíže. Je prokazatelně efektivní pro zvýšení výkonnosti, zejména při opakované krátkodobé intenzivní zátěži a v silových disciplínách. Nejúčinnějším postupem podávání je využívání tzv. plnící fáze, následované fází udržovací a pauzou, které se v cyklech opakují. Účinnost zvyšuje současné podání sacharidů. Nárůst výkonnosti koreluje s velikostí nárůstu obsahu kreatinu ve svalech, která závisí na velikosti jeho zásob před zahájením suplementace. Karnitin se vyskytuje ve dvou optických formách, ovšem pouze L-forma je metabolicky účinná a bezpečná. Jeho hlavní funkcí je přenos aktivovaných mastných kyselin do matrix mitochondrie, kde probíhá jejich β-oxidace. Denní potřeba karnitinu je z 25 % kryta biosyntézou, zbylých 75 % ...

IVANOVÁ, Markéta
Iodine is a trace element that is essential for the production of thyroid hormones triiodothyronine and thyroxine. Iodine deficiency had in the past result in many serious diseases and disorders. At present is in the Czech Republic considered mastered. However, Iodine deficiency are vulnerable to specific groups of the population, including pregnant and nursing women, because of their need and the recommended daily dose of iodine is increased. Breastfeeding women should receive adequate amounts of dietary iodine for optimal saturation for themselves and their child. Otherwise, exposing themselves and their child risk of diseases and disorders of iodine deficiency. Increased supply of iodine can be replaced by eating foods rich in iodine. In the event that you cannot increase intake of iodine - rich food preferences in iodine, there are various supplements that contain iodine. The aim of this thesis was to evaluate the intake of iodine supplements and supplements in nursing women and breast-feeding women to assess the awareness for greater needs of iodine and food iodine sources. There were set up the three research questions: How many nursing women used to supply iodine supplements and supplements?, What is the awareness of breastfeeding women need more iodine? and What is the awareness of breastfeeding women about dietary sources of iodine? A quantitative research strategy was used for the implementation of the research. The method used for data collection was made by an anonymous questionnaire. A questionnaire was handed in a printed copy to pediatricians and gynecologists in the southern Bohemia. With the doctors help were invited nursing women to fulfill the questionnaire. Part of the women was invited to complete the questionnaire directly. The research sample consisted of 117 female respondents. The research shows that 62 % of breastfeeding women know why it is important to increased need for iodine during lactation. But only 9 % of women know all the risks of iodine deficiency on the mother mentioned in the questionnaire and only one new mother knows all risk of iodine deficiency for infants listed in the questionnaire. The recommended daily intake of iodine properly reported or estimated 40.2 % of women. It turned out that 46 % of respondents from the research group used food supplements and supplements containing iodine. Each of these respondents used only one preparation with iodine. The most commonly used products were: GS mamavit, a Smart baby and Femibion 400 and Gravital. 43 % of respondents had used a dietary supplement containing iodine from the beginning of pregnancy and in 57 % of the respondents were informed about food supplements through a doctor (gynecologist, pediatrician). The results showed that awareness of breastfeeding women about food sources of iodine is not good. 67 % of women know that settlement higher needs iodine during lactation is possible by eating foods rich in iodine, but all food sources of iodine in the questionnaires (sea fish, seafood and seaweed, iodized salt, and milk and dairy products) registered only one respondent. 39 % of women known as a rich source of iodine, seafood, seafood and seaweed, iodized salt , but none of them knew that the rich and a good source of iodine is also milk and dairy products. Based on the results of the work would be desirable to issue educational print disabled educational material that could be used to increase awareness of not only women who are breastfeeding, pregnant women as well as the higher of the recommended daily dose of iodine and what foods to include in your diet in order to pay the increased intake of iodine. Provide information on supplements containing iodine, which can add missing quantities of iodine, what products are available and what are the currently preferred by nursing women.

KRATOCHVÍLOVÁ, Zuzana
Bachelor's thesis concentrates on functions of selenium in human nutrition. Selenium is an essential trace element of importance to human health. Its availability depends on the concentration of selenium in the soil. The average income of selenium in the Czech population are usually 36 g/day per individuals. Excess or insufficient selenium intakes can result in adverse effects on human health. The most important sources of selenium in the diets of most people are meat, fish, eggs, milk, cereals and nuts. Selenium plays an important role in a number of metabolic functions including antioxidant systems, thyroid hormone metabolism, immune function and reproduction. Low selenium status are associated with increased risk of mortality, poor immune function, and cognitive decline, while high selenium status cause garlic breath, hair and nail loss, disorders of the nervous system and skink and poor dental health. Amount of selenium and its need changes during life. Recommended doses of selenium for women are 55 g/day and for men 70 g/day. Pregnant and lactating women require an average of 65-75 g selenium/day. Selenium deficiency in women causes problems with pregnancy, fetal malformations or postnatal complications. Newborn baby receives in breast milk about 10 g selenium/day. The recommended doses for children are in the range of 20-30 g selenium/day. The lack of selenium in seniors causes loss of muscle mass and strenght. Conversely sufficient doses of selenium can prevent the development of osteoporosis and various health complications. During sport aktivity, in the body there arise a large amount of free radicals and that is why it is necessary to suply the body of a sufficient amount of selenim, which helps prevent with its antioxidant effect oxidative damage of the muscles. The population exposed to low levels of selenium, the lack can be increased by use of dietary supplements with selenium.
