Abstract
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.
Abstract (english)
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.
