Background: The purpose of this study was to determine the changes in erythropoiesis and iron metabolism indicators in order to improve the maintenance of athletic performance during rapid weight loss. Methods: The subjects were 23 university wrestlers (13 male, 10 female). The first measurements in the male and female groups after natural iron supplement intake indicated weight decreases of 6.2% and 5.8%, respectively. After the 3-week washout period, the weights in the male and female groups decreased by 6.1% and 6.2%, respectively. Results: Males in the intake group experienced changes in iron metabolism after weight loss, as shown by increases in the iron indicators (Fe, p
