Numerous reports have described a poor iron status in female endurance athletes. Horvever, the traditionally applied indicators of iron status (hemoglobin, ferritin, transferrin) may not truly reflect the iron status. Therefore we studied the nervly developed soluble transferrin receptor and other indicators of iron status in twelve female endurance athletes before and after a triathlon race. Resting values showed a poor iron status in the participants of the race. Serum TfR concentration increased slightly after the race. However, if the values are corrected for hemoconcentration no change could be found. Hemoglobin, serum ferritin and transferrin values were increased after the race. (Clin.
