Abstract

Cilj ovog istraživanja bio je utvrditi status vitamina D kod vrhunskih hrvatskih sportaša tijekom lipnja i napraviti sustavni pregled literature koja govori o statusu vitamina D kod sportaša diljem svijeta. U istraživanje je uključeno 20 vrhunskih hrvatskih sportaša koji su osvajači medalja na europskim i svjetskim prvenstvima te Olimpijskim igrama. Koncentracije 25(OH)D (kalcidiola) u serumu bile su: <50 nmol/L (deficijencija vitamina D) kod 2 sportaša (10 %), od 50-75 nmol/L (insuficijencija) kod njih 9 (45 %), a samo je 9 ispitanika imalo koncentraciju >75 nmol/L koja se smatra suficijentnom. Ovi rezultati nešto su lošiji u usporedbi s rezultatima iz 18 studija provedenih od 2020. do 2022. u kojima se određivao status 25(OH)D, naime 55 % hrvatskih sportaša imalo je neadekvatnu razinu vitamina D u usporedbi s 35,1 % iz ostalih nedavnih studija. Potrebna su dodatna istraživanja na sportašima kako bi se uočila uzročno-posljedična veza statusa 25(OH)D i sportske izvedbe, ali i bolja edukacija sportaša o važnosti vitamina D.

Abstract (english)

The aim of this research was to determine vitamin D status of elite Croatian athletes during June and to make a systematic review of new literature about vitamin D status of athletes around the world. This research included 20 elite Croatian athletes that won medals at european, world championships and/or the Olympic games. 25(OH)D (calcidiol) concentrations in serum were: <50 nmol/L (vitamin D deficiency) in 2 athletes (10 %), 50-75 nmol/L (insufficiency) in 9 (45 %), and only 9 athletes had a concentration >75 nmol/L, which is considered sufficient. These results are even lower compared to results from 18 studies conducted from 2020-2022 in which 25(OH)D status was determined, namely 55 % of Croatian athletes had inadequate vitamin D levels compared to 35.1 % athletes in other recent studies. Additional research on athletes is needed in order to observe the cause-and-effect relationship between 25(OH)D status and sports performance, as well as better education of athletes about the importance of vitamin D.
