Abstract

U anemičnih osoba, nedostatak željeza često narušava ne samo sportsku izvedbu, već i imunološki sustav i dovodi do brojnih fizioloških disfunkcija. Kod sportaša, a posebno sportašica, neadekvatan nutritivni status željeza i prije pojave anemije može negativno utjecati na izvedbu. Cilj ovog rada bio je provjeriti hipotezu da je vjerojatnost nedostatnog unosa željeza veća u sportskoj populaciji, osobito u mlađih sportašica. U istraživanju je sudjelovalo 10 sportašica kuglačkog kluba Zagreb-Zabokya dobi 16-25 godina. Na temelju jednodnevnih dnevnika prehrane uz vaganje procijenjen je unos željeza te komponenti hrane koje djeluju kao inhibitori (fitati) i pojačivači apsorpcije (vitamin C). Prosječan dnevni unos željeza bio je 13,4 mg (u rasponu 4-16 mg). Za usporedbu, slična istraživanja navode unos od 10,7 ± 2,7 mg. Na temelju sličnih, a i ovog istraživanja, može se zaključiti da je uobičajena potrošnja hrane siromašne željezom glavni čimbenik u etiologiji nedostatka željeza među sportašicama.

Abstract (english)

In anaemic individuals, iron deficiency anaemia not only impairs athletic performance but also immune function and causes many other physiological dysfunctions. For athletes, especially female athletes, inadequate nutritional status of iron and before the onset of anaemia may adversely affect performance. The aim of this work was to test that the prevalence of insufficient iron intake is likely to be higher in athletic populations, especially in younger female athletes. The study included 10 female athletes bowling club in Zagreb Zaboky aged 16-25 years. Based on a food record with weighing, intake of iron and food components which are inhibitors (phytates) and absorption (vitamin C) was estimated. The mean iron intake was 13.4 mg (range was 4 to 16 mg). For comparison, previous studies reported intake among female athletes of 10.7 ± 2.7 mg. According to this and other researches this suggests that the habitual consumption of iron-poor diets is a major factor in the etiology of iron deficiency among athletes'.
