Abstract

U vrhunskom nogometu sportašice su izložene velikoj potrošnji energije zbog svakodnevnih treninga i čestih utakmica. Neke sportašice ne unose adekvatnu količinu energije, što dovodi do rizika od pojave niske raspoložive energije (NRE). U ovom radu istražene su razine raspoložive energije (RE) kod 23 vrhunske nogometašice u dobi 18-29 godina tijekom natjecateljskog tjedna. Pomoću podataka o nemasnoj tjelesnoj masi (NM) dobivenih antropometrijskim mjerenjima, energetskom unosu iz sedmodnevnih dnevnika prehrane i energetskoj potrošnji iz dnevnika energetske potrošnje, uz primjenu kompendija potrošnje energije različitih tjelesnih aktivnosti, izračunate su razine RE (kcal/kg NM). Korišten je upitnik za identifikaciju NRE u sportašica, koji se pokazao nepouzdanim u procjeni NRE kod nogometašica. Uočeno je da u natjecateljskom tjednu 65% nogometašica ima NRE, 35% reduciranu RE, dok optimalnu RE nema ni jedna nogometašica. Prosječna RE iznosi 26,3 ± 9,5 kcal/kg NM.

Abstract (english)

In elite football, female athletes are exposed to high energy expenditure due to daily training and frequent matches. Some athletes do not consume an adequate amount of energy, which leads to the risk of low energy availability (NRE). This study investigated the levels of energy availability (EA) in 23 elite female football players aged 18-29 during a competitive week. EA levels (kcal/kg NM) were calculated using data on fat-free mass (NM) obtained from anthropometric measurements, energy intake from seven-day food diaries and energy expenditure from expenditure diaries, along with the application of the energy expenditure compendium for various physical activities. The low energy availability in females questionnaire was used, which proved unreliable in assessing NRE in football players. It was observed that during the competitive week 65% of the players had NRE, 35% had reduced EA and none had optimal EA. The average EA was 26.3 ± 9.5 kcal/kg NM.
