The aim of the study was to investigate the changes of some indicators of iron status in elite soccer players throughout a competitive season. Methods: In the study participating 16 male professional soccer players. The measurements performed at the beginning of the season, after the re-building period, at the middle and at the end of the season. The indicators that measured were hematocrit, hemoglobin, serum iron and ferritin. Results: Hematocrit and serum iron decreased significantly during the season (p<0.05). Ferritn decreased after the re-building period (p<0.05) and then increased at the end of the season (p<0.05). Conclusion: Iron depletion is very common between elite soccer players and ferritin seems to be related to the training phase during the sport season.
