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 % ...
