Abstract

Uzrok rapidnog porasta popularnosti američkog nogometa na tlu Republike Hrvatske je globalizacija svijeta u zadnjih dvadeset godina. Cilj ovog istraživanja bio je u defenzivnih i ofenzivnih igrača američkog nogometa procijeniti i usporediti unos energije i nutrijenata s antropometrijskim karakteristikama specifičnim za navedene pozicije. U istraživanju je sudjelovalo 50 igrača iz dva hrvatska kluba. Metodom bioelektrične impedancije određen je sastav tijela, podaci o prosječnom dnevnom unosu energije i nutrijenata prikupljeni su trodnevnim dnevnikom prehrane, dok je MEDAS upitnikom procijenjeno pridržavanje mediteranskog obrasca prehrane. Nije utvrđena statistički značajna razlika u antropometrijskim parametrima izmjerenima na početku predsezone natjecanja između defenzivnih i ofenzivnih jedinica, a mjerenjem na kraju predsezone natjecanja statistički značajna razlika utvrđena je u udjelu mišićnog tkiva (p=0,041). Prehrana sportaša deficitarna je na unosu proteina i ugljikohidrata, dok unos zasićenih masnih kiselina, kolesterola i natrija premašuje preporuke kod obe pozicijske jedinice. Prosječan rezultat MEDAS upitnika ne ukazuju na pridržavanje mediteranskog obrasca prehrane (4,7 ± 2,2 bodova). Nutritivna intervencija na deficitarnom unosu proteina i ugljikohidrata može biti jedan od faktora za dodatno povećanje udjela mišićnog tkiva tijekom faze pripreme.

Abstract (english)

The reason for the rapid increase in the popularity of American football on the soil of the Republic of Croatia is the globalization of the world in the last twenty years. The aim of this research was to evaluate and compare the intake of energy and nutrients with the anthropometric characteristics specific to the mentioned positions in defensive and offensive American football players. 50 players from two Croatian clubs participated in the research. Body composition was determined using the bioelectrical impedance method, data on the average daily intake of energy and nutrients were collected through a three-day food diary, while adherence to the Mediterranean diet was assessed using the MEDAS questionnaire. No statistically significant difference was found in the anthropometric parameters measured at the beginning of the pre-season competition between defensive and offensive units, and when measured at the end of the pre-season competition, a statistically significant difference was found in the proportion of muscle tissue (p=0.041). The diet of athletes is deficient in the intake of proteins and carbohydrates, while the intake of saturated fatty acids, cholesterol and sodium exceeds the recommendations of both positional units. The average result of the MEDAS questionnaire does not indicate adherence to the Mediterranean diet (4.7 ± 2.2 points). Nutritional intervention on the deficient intake of proteins and carbohydrates can be one of the factors for an additional increase in the proportion of muscle tissue during the preparation phase.
