Cilj ovog rada bio je dvostruko slijepom studijom utvrditi povezanost unosa prehrambenih vlakana subjektivnog osjećaja umora u sportaša tijekom treninga ili utakmica. Ispitanici su bili mladi košarkaši (n=17) iz istog tima. U ovom radu korištene su antropometrijske metode, a od dijetetičkih metoda korišteni su dnevnici prehrane i 24-satna prisjećanja o unosu hrane i pića. Prije početka istraživanja sportaši su nasumično podijeljeni u dvije grupe: interventnu grupu koja je uzimala prehrambena vlakna u obliku dodataka prehrani Nutriose® i kontrolnu grupu koja je uzimala maltodekstrin kao placebo. Prije početka intervencije analizom dnevnika prehrane utvrđeno je da nije bilo razlika između početnog unosa prehrambenih vlakana kroz uobičajenu prehranu, kao ni razlika u unosu energije i udjela makronutrijenata u dnevnom unosu između dvije grupe. Prilikom mjerenja RPE (engl. Rate of Perceived Exertion) vrijednosti prije i nakon intervencije dokazano je smanjenje subjektivnog osjećaja umora među ispitanicima u interventnoj grupi (p=0,0049). Ispitanici u interventnoj grupi unosili su više ukupnih proteina (p=0,030), životinjskih proteina (p=0,032) i masti (p=0,020). Nakon provedene Pearsonove korelacije (R2 >0,5625) nije se izdvojio niti jedan mikronutrijent zaslužan za subjektivno smanjenje osjećaja umora. Povećani unos prehrambenih vlakana može biti mogući alat za pomoć pri subjektivnom smanjenju osjećaja umora. This thesis' goal was to objectively assess possible correlation between intake of dietary fiber and sports performance, especially on subjective rate of perceived exertion during training and/or competition. Participants were all young basketball players (n=17) coming from the same team. Methods used in this research were the following: anthropometric tests, 3-day food records and 24-hour dietary recall. Before the beginning of the intervention athletes were divided in 2 groups (randomly): experimental group that took additional dietary fiber in the form of Nutriose® product and control group that took maltodextrin as placebo. Upon analysis of food records it was discovered that there were no significant differences between groups in the intake of dietary fiber, energy or discrepancy between ratios of macronutrients. After testing RPE (Rate of Perceived Exertion) ratings it was concluded that intake of additional soluble fiber reduced perceived exertion of the experimental group (p=0.0049). No statistical significance was observed between the groups, regarding the intake of macronutrients except that participants in the experimental group ingested more total protein (p=0.030), animal protein (p=0.032) and fat (p=0.020). After the Pearson correlation test was performed (R2>0.5625), the results indicated that none of the micronutrients had an observable effect on reducing the rate of perceived exertion. The results indicate that higher intake of dietary fiber can be a good addition for possible reduction of subjective feeling of fatigue.

Cilj ovog rada bio je utvrditi cjelodnevni unos energije, makronutrijenata i prehrambenih navika studenata Farmaceutsko-biokemijskog fakulteta Sveučilišta u Zagrebu te usporediti u kojoj se mjeri one podudaraju s preporučenim smjernicama pravilne prehrane za navedenu populacijsku skupinu. Ispitivanjem je obuhvaćeno 8 muških i 21 ženskih ispitanika u dobi od 22. do 24. godine. Korištena dijetetička metoda je četverodnevni dnevnik prehrane. Ispunjeni dnevnici prehrane su obrađeni u računalnom programu Excel korištenjem nutritivnih vrijednosti USDA tablica sa sastavom namirnica i pića Prikupljeni podaci su izraženi na skupine kreirane obzirom na spol. Utvrđeno je da prosječan dnevni unos energije i prehambenih vlakana manji od preporučene vrijednosti. Prosječan dnevni unos proteina, zasićenih masnih kiselina i kolesterola veći je od preporuka. Unos polinezasićenih masnih kiselina kao i doprinos ugljikohidrata i masti ukupnom kalorijskom unosu nalazi se unutar preporuka. Utvrđena je statistički značajna razlika preskakanja obroka obzirom na spol. Istraživanje na temu prehrambenih navika studenata bilježi odstupanja od preporuka za zdrav životni stil, te je poželjno organizirati različite radionice i predavanja na temu pravilne prehrane, kako bi se studenti educirali o pravilnoj prehrani sukladnoj njihovim potrebama. The aim of this investigation was to examine daily energy intake, macronutrients consummation and dietary habits of students of the Faculty of Pharmacy and Biochemistry (University of Zagreb). Particularly, we wanted to determine the extent to which they match with dietary guidelines for proper nutrition for the mentioned population group. The study included 8 males and 21 female subjects aged 22 to 24 years. The dietetic method used in study is a four-day food diary. Filled food diaries were processed in the Excel program using the USDA charts with nutritional values for food and drink. The collected data were expressed for each gender-related subgroup. The results showed that mean daily intakes of energy and dietary fibers were lower than the recommended values. The meann dietary intakes of protein, saturated fatty acids and cholesterol were above the recommended levels. The intake of polyunsaturated fatty acids as well as the contribution of carbohydrates and fat to total caloric intake was contained within the recommendations. It has been established that there was statistically significant difference in the frequency of skipping meals between males and females. This study showed deviations from the guidelines for healthy lifestyle. It would be advisable to organize different workshops and lectures on this topic, in order to educate students about proper nutrition that complies with their physical needs.
