Abstract

Cilj ovog rada bio je utvrditi utjecaj topivih prehrambenih vlakana na sportsku učinkovitost košarkaša, odnosno na neuromuskularnu izdržljivost eksplozivne snage vertikalnog tipa i tipa sprint, te na kardiovaskularnu izdržljivost aerobnog i anaerobnog tipa kod košarkaša. Također, cilj je bio utvrditi utjecaj topivih prehrambenih vlakana na odgodu umora kod košarkaša. Istraživanje je uključilo 18 mladih, punoljetnih košarkaša istog košarkaškog tima, u natjecateljskom dijelu sezone. Prehrambene navike košarkaša i unos vlakana procijenjene su temeljem trodnevnog dnevnika prehrane te je njihova konzistentnost, za vrijeme intervencije, provjeravana 24-satnim prisjećanjem. Određivanje morfološkog statusa rađeno je uz mjerenja sportske učinkovitosti. Za mjerenje neuromuskularne izdržljivosti koristili smo testove za procjenu eksplozivne snage tipa sprinta (5 m, 10 m i 20 m sprint) i eksplozivne snage vertikalnog tipa (skok bez pripreme iz čučnja, skok s pripremom, jednonožni skok s pripremom, maksimalni skok s pripremom uz zamah rukama, ponavljajući skokovi s pripremom, te pet ponavljajućih skokova iz stopala). Za procjenu kardiovaskularne izdržljivosti koristili smo testove za procjenu izdržljivosti aerobnog tipa (BEEP test), te test za procjenu izdržljivosti anaerobnog tipa (300 m (15x20 m)). Istraživanje je pokazalo da suplementacija sa 17 g topivih prehrambenih vlakana tijekom 4 tjedna nema utjecaja na sportsku učinkovitost neuromuskularne i kardiovaskularne izdržljivosti. Istraživanje je pokazalo i statistički značajnu odgodu umora kod košarkaša. Intervencija suplementacije topivim prehrambenim vlaknima pokazala se neučinkovita na sportske performanse, a smanjila je subjektivni osjet umora kod košarkaša tijekom natjecateljske sezone.

Abstract (english)

The aim of this study was to determine the influence of soluble dietary fiber on the sports performance of basketball players, that is, on the neuromuscular endurance of vertical and sprint explosive strength, and on the aerobic and anaerobic cardiovascular endurance of basketball players. Also, the goal was to determine the influence of soluble dietary fiber on delaying fatigue in basketball players. The research included 18 young, adult basketball players of the same basketball team, in the competitive part of the season. The basketball players' eating habits and fiber intake were assessed based on a three-day food diary, and their consistency during the intervention was checked by 24-hour recall. Determination of morphological status was done along with measurements of sports performance. To measure neuromuscular endurance, we used tests to assess sprint-type explosive power (5 m, 10 m and 20 m sprint) and vertical-type explosive power (jump without preparation from a squat, jump with preparation, one-legged jump with preparation, maximum jump with preparation with swing hands, repeated jumps with preparation, and five repeated jumps from the feet). To assess cardiovascular endurance, we used aerobic endurance tests (BEEP test) and anaerobic endurance tests (300 m (15x20 m)). Research has shown that supplementation with 17 g of soluble dietary fiber for 4 weeks has no effect on the sports performance of neuromuscular and cardiovascular endurance. The research also showed a statistically significant delay in fatigue in basketball players. The intervention of supplementation with soluble dietary fiber proved to be ineffective on sports performance, and it reduced the feeling of fatigue in basketball players during the competitive season.
