Abstract

Tjelesna aktivnost trebala bi biti sastavni dio života svakog pojedinca. U novije vrijeme zabilježen je trend porasta neredovitog provođenja aktivnosti odnosno neaktivnosti. Crijevna mikrobiota zajednica je mikroorganizama koji nastanjuju probavni trakt, vrlo je kompleksna te je podložna promjenama tijekom vremena, a posebice pod utjecajem različitih čimbenika, kao što je prehrana, a ispituje se i kakav je utjecaj životnog stila što uključuje i tjelesnu aktivnost. Cilj ovoga rada bio je utvrditi postojanje povezanosti utjecaja stupnja tjelesne aktivnosti na sastav crijevne mikrobiote u mlađoj populacijskoj skupini, različitog stupnja uhranjenosti. U istraživanje je uključeno 40 ispitanika, oba spola, prosječne dobi 25,8 ± 4,3 godina. Ispitanici su raspodijeljeni u tri skupine s obzirom na stupanj uhranjenosti. Tjelesna aktivnost se procjenjivala upitnikom o tjelesnoj aktivnosti - GPAQ. S obzirom na prikupljene podatke te povezujući tjelesnu aktivnost i sastav mikrobiote ne može se donijeti konzistentan zaključak, no može se primijetiti trend promjena udjela bakterijskih vrsta koljena Firmicutes i Bacteroidetes.

Abstract (english)

Physical activity should be a part of everyday life of every individual. Recently, there has been a growing trend of people that are physically inactive. The intestinal microbiota is a group of microorganisms that inhabit intestinal tract, it is immensely complex and is susceptible to change, especially under the influence of various factors, such as nutrition. Studies are also being performed in order to prove an impact of a regular physical activity. The main goal of this thesis was to prove the influence of the amount of physical activity on the intestinal microbiota, in younger population and different body masses. The research included 40 individuals of both sexes, average age 25.8 ± 4.3 years. Subjects were divided in three different groups depending on their body mass index. The physical activity was being estimated by Global Physical Activity Questionnaire - GPAQ. Based on the research and the collected data on the relationship between physical activity and the intestinal microbiota no consistent conclusion can be made, however the change of the amount of Firmicutes and Bacteroidetes bacteria is noticeable.
