Abstract

Kreatin je prirodna supstanca koja se nalazi u ljudskom tijelu i ima važnu ulogu u energetskom metabolizmu mišića. Osim toga, kreatin je jedan od najopsežnije proučavanih i klinički najučinkovitijih dodataka prehrani u smislu mogućnosti brze apsorpcije od strane mišića i sposobnosti povećanja izdržljivosti tijekom kratkih razdoblja vježbi visokog intenziteta. U tu svrhu kreatin prvenstveno koriste sportaši i osobe koje se bave trening s otporom budući da veće količine kreatina u mišićima osiguravaju bržu regeneraciju ATP-a i veće količine energije. Provedena ispitivanja pokazuju kako suplementacija kreatinom omogućuje poboljšanje izvedbe vježbanja, poboljšanje snage i veličine mišića te olakšavanje oporavka nakon intenzivnih treninga. U ovom radu, na temelju proučavanja prethodno provedenih eksperimentalnih istraživanja, objašnjeni su učinci suplementacije kreatinom kod različitih sportaša i ostalih skupina kao što su prethodno neutrenirane osobe, djeca i adolescenti te starije odrasle osobe te je također utvrđena i sama sigurnost suplementacije kreatinom.

Abstract (english)

Creatine is a natural substance found in the human body and plays a significant role in muscle energy metabolism. In addition, creatine is one of the most extensively studied and clinically effective dietary supplements in terms of its ability to be absorbed faster by the muscles and its ability to increase endurance during short periods of high-intensity exercise. For this purpose, creatine is primarily used by athletes and people engaged in resistance training, since larger amounts of creatine in the muscles ensure rapid regeneration of ATP and greater amounts of energy. Conducted tests show that creatine supplementation improves exercise performance, increases muscle strength and size, and facilitates recovery after intense training. In this paper, based on the study of previously conducted experimental research, the effects of creatine supplementation in different athletes and other groups such as previously untrained people, children and adolescents and older adults are explained, and the safety of creatine supplementation is also examined.
