Alhaiseen energiansaatavuuteen ja erityisesti suhteelliseen energiavajeeseen liittyv\u00e4 tutkimus on viimeisen vuosikymmenen aikana lis\u00e4\u00e4ntynyt merkitt\u00e4v\u00e4sti. Energiansaatavuuden mahdollisista vaikutuksista rautastatukseen on kuitenkin saatu ristiriitaista tietoa. Sek\u00e4 heikko rautatila ett\u00e4 suhteellinen energiavaje vaikuttavat kokonaisvaltaisesti suorituskykyyn sek\u00e4 terveyteen. Aiheen tutkiminen on t\u00e4rke\u00e4\u00e4, jotta voidaan l\u00f6yt\u00e4\u00e4 keinoja riskiss\u00e4 olevien urheilijoiden tunnistamiseksi. Aikaisen diagnosoinnin ja hoidon avulla voidaan puolestaan ehk\u00e4ist\u00e4 negatiivisia vaikutuksia. Alhaisen energiansaatavuuden tutkimiselle haasteita asettaa muun muassa kultaisen standardin sek\u00e4 tarkkojen raja-arvojen puuttuminen. Aiemmissa tutkimuksissa riitt\u00e4m\u00e4tt\u00f6m\u00e4n energiansaannin on havaittu vaikuttavan veren biomarkkereihin.

Kirjallisuuskatsaukseen valikoitui yhteens\u00e4 seitsem\u00e4n tutkimusta. Katsaukseen valikoitui kaksi satunnaistettua kontrolloitua tutkimusta, kolme poikkileikkaustutkimusta, yksi kohorttitutkimus sek\u00e4 yksi tapaussarjatutkimus. Kuudessa tutkimuksessa tutkittiin alhaisen energiansaatavuuden vaikutusta rautastatukseen veren biomarkkereiden avulla. Yhdess\u00e4 tutkimuksessa rautastatuksen arviointi perustui tutkittavan itsearviointiin. \n\nKirjallisuuskatsauksessa saadut tulokset osoittavat, ett\u00e4 n\u00e4ytt\u00f6 rautastatuksen biomarkkereiden k\u00e4yt\u00f6st\u00e4 alhaisen energiansaatavuuden arvioinnissa on toistaiseksi riitt\u00e4m\u00e4t\u00f6nt\u00e4. Osassa katsauksen tutkimuksista saatiin aiempaa tutkimustietoa vastaavia tuloksia esimerkiksi hemoglobiinin osalta. Tuloksissa oli kuitenkin suurta hajontaa eik\u00e4 niist\u00e4 voida tehd\u00e4 yleistett\u00e4vi\u00e4 johtop\u00e4\u00e4t\u00f6ksi\u00e4.
