Purpose: Rhythmic gymnasts sometimes develop severe iron-deficiency anemia. Preventing such anemia could thus enhance both their performance and health. We compared the relationship between a dietary intervention and RBC metabolism. Methods: Ten female rhythmic gymnasts were recruited for this study. Changes in the RBC delta-aminolevulinate dehydratase (δ-ALAD) activity were used as an index of biosynthesis, and changes in the haptoglobin (hp) were used to assess degradation. Results: Duringthe one month intervention period, the athletes consumed traditional Japanese foods which provide 1500 kcal energy, 2g/kg body weight protein, 200g carbohydrate and 15mg iron. No main effect of this intervention on the hematological indexes was observed. The (δ-ALAD activity was significantly greater in August than in July or September. Hp concentration was significantly lower in August in comparison to the other periods. Conclusion: Dietary intervention might enhance the RBC turnover by increasing the capacity for erythrocyte biosynthesis and degradation.
