Introduction:
Volleyball practice requires repeated impacts on arms and feet caused by vertical jumps, falls, auctions, sudden and rapid changes of direction, which is why might raise us problems in the metabolism of iron (Fe) and the recommended intake of 18 mg/day (in the women in general), is not sufficient to meet the needs of the players of volleyball female (JVF).
Objective:
We analyzed the FS and IST of 10 JVF a team of Spanish SuperLeague (26.6 ± 5.9 years and height 178.05 ± 8.7 cm) in two moments of the season: Week 0 (pre-start of preseason) and week 11 (after 11 weeks of training and 6 games of the regular season). Also calculated Fe intake in this period with consumption frequency questionnaire developed and tested with food dietary records of 7 days.
Results:
We observed that an intake of 25.8 mg/day of dietary Fe is not sufficient to prevent 30% of the JVF suffer pre-latent iron deficiency and 20% latent deficit (pre-anemia).
Conclusion:
It could be recommended conducting periodic blood analytical and a food education, teaching which foods containing a high content of Fe-type heme, and the factors that can interfere with absorption.
