20.500.12556/RUL-188053 Ustreznost prehranskega vnosa mladih profesionalnih kolesarjev v tekmovalni sezoni Adequacy of nutritional intakes of young professional cyclists during the competitive season V magistrski nalogi smo proučevali ustreznost prehranskega vnosa mladih profesionalnih kolesarjev v tekmovalni sezoni. Namen raziskave je bil ugotoviti, ali njihova prehranska strategija v tekmovalnem obdobju sledi smernicam klinične športne prehrane. V raziskavo je bilo vključenih 14 kolesarjev dveh kontinentalnih ekip, v končno analizo pa 13. Prehranski vnos smo ocenili s tridnevnimi prehranskimi dnevniki, fotografiranjem obrokov in dodatnimi opisi zaužite hrane, tekočine ter prehranskih dopolnil. Podatke smo analizirali s pomočjo Odprte platforme za klinično prehrano, energijsko porabo med aktivnostjo ocenili z MET-vrednostmi, energijo v mirovanju pa s Harris-Benedictovo enačbo. Povprečni tridnevni energijski vnos je znašal 4147 ± 760 kcal/dan, vnos ogljikovih hidratov 9,1 ± 2,3 g/kg TM/dan, beljakovin 2,3 ± 0,4 g/kg TM/dan, maščob 22 % ± 5,3 % energijskega vnosa in prehranske vlaknine 22,7 ± 4,2 g/dan. Na dan dirke se je v primerjavi z dnevom pred dirko statistično značilno povečal vnos ogljikovih hidratov, medtem ko sta se delež maščob in vnos prehranske vlaknine statistično značilno zmanjšala. Povprečni tridnevni vnos beljakovin je znašal 2,20 ± 0,47 g/kg TM/dan in je bil statistično značilno višji od spodnje meje priporočila. Vnos ogljikovih hidratov iz izdelkov športne prehrane je bil pri večini kolesarjev ustrezen in na dan dirke statistično značilno višji kot dan pred dirko, medtem ko je bila uporaba prehranskih dopolnil raznolika in nepovsem sistematična. Ugotavljamo, da kolesarji prehrano okoli tekmovalnega dne deloma prilagajajo zahtevam dirke, vendar ostajajo pomembne razlike med posamezniki, zato je ključna individualizirana in periodizirana prehranska podpora. This master’s thesis examined the adequacy of nutritional intake in young professional cyclists during the competitive season. The aim of the study was to determine whether their dietary strategy during the competition period follows clinical sports nutrition guidelines. Fourteen cyclists from two continental teams were included, and 13 were retained in the final analysis. Dietary intake was assessed using three-day food diaries, meal photographs, and detailed descriptions of foods, fluids, and dietary supplements consumed. The data were analysed using the Open Platform for Clinical Nutrition, exercise energy expenditure was estimated using MET values, and resting energy expenditure was calculated with the Harris-Benedict equation. Mean three-day energy intake was 4147 ± 760 kcal/day, carbohydrate intake 9.1 ± 2.3 g/kg body mass/day, protein intake 2.3 ± 0.4 g/kg body mass/day, fat intake 22% ± 5.3% of total energy intake, and dietary fibre intake 22.7 ± 4.2 g/day. Compared with the day before the race, race-day carbohydrate intake increased significantly, whereas fat intake and dietary fibre intake decreased significantly. Mean three-day protein intake was 2.20 ± 0.47 g/kg body mass/day and was significantly higher than the lower recommended limit. Carbohydrate intake from sports foods was adequate in most cyclists and was significantly higher on race day than on the day before the race, whereas the use of dietary supplements was diverse and not fully systematic. The findings indicate that cyclists partly adapt their diet to the demands of competition; however, substantial inter-individual differences remain, highlighting the importance of individualized and periodized nutritional support. prehrana športnikov mladi profesionalni kolesarji tekmovalna sezona prehranski vnos ogljikovi hidrati beljakovine prehranska dopolnila prehranska strategija young professional cyclists nutritional intake competitive season athlete's diet carbohydrates proteins dietary supplements nutritional strategy true false false [E.
