Abstract

Skijanje i daskanje na snijegu su popularne zimske rekreativne i natjecateljske aktivnosti. S obzirom na to da se odvijaju u ekstremnim okolišnim uvjetima, uz fizičku pripremu vrlo je bitna i prehrana kako bi se ostvario željeni uspjeh. Dosadašnja istraživanja na ovu temu uočila su veliki unos proteina i masti kod skijaša natjecatelja.
Cilj ovog rada je dijetetičkom metodom, 7-dnevnim dnevnikom prehrane procijeniti prehrambeni unos energije, makronutrijenata i mikronutrijenata te tekućine kod hrvatske i svjetske juniorske prvakinje u alpskom skijanju. Dobiveni podaci analizirani su uz pomoć USDA baze podataka. Iz rezultata je vidljiv energetski deficit te je primjenom koncepta raspoložive energije utvrđena razina od 2493,9 kcal/kg nemasne TM, nizak unos ugljikohidrata (< 6 – 10 g kgˉ¹ TM), vitamina D i E te kalcija. Zamijećen je visok unos proteina (> 1,4 – 1,7 g kg ˉ¹TM) i masti (> 20 - 35 % kcal) dok je stupanj hidracije adekvatan na temelju rezultata iz 7-dnevnog dnevnika prehrane.

Abstract (english)

Skiing and snowboarding are popular winter recreational and competitive activities. Since they take place in extreme environmental conditions, with physical preparation, nutrition is also very important in order to achieve the desired success. Previous research on this topic has discovered high protein and fat intake in skiers competitors.
The aim of this work is to evaluate dietary intake of energy, macronutrients, micronutrients and fluids in Croatian and world junior champion in alpine skiing. The obtained data were analyzed using the USDA database. The results showed an energy deficit and the concept of available energy established a level of 2493,9 kcal/kg low BM, low carbohydrate intake (< 6-10 g kgˉ¹ TM), vitamin D and E and calcium. High protein intake (> 1.4-1.7 g kgˉ¹ TM) and fat (> 20-35% kcal) were observed, while the hydration status was adequate based on results from the 7-day diet diary.
