Brief Summary:

Effect of intravenous iron substitution (iron carboxymaltose (Ferinject®), total dose 15 mg/ kg (maximal dose: 1000mg) in 250 ml 0.9 % NaCl; intravenous infusion in 20 min)in non-anemic premenopausal women with iron deficiency on

Primary objective:

- Mitochondrial capacity (Phosphocreatine Recovery rate assessed by 31P-MR-spectroscopy of the lower leg muscle)

Secondary objectives:

  • Maximal oxygen uptake during a graded cycling exercise test and time to exhaustion at submaximal power during a constant-load cycling exercise test
  • Plantarflexor muscle fatiguability as assessed by isokinetic dynamometry
  • Trial with medicinal product

Intervention Details:
  • Drug: Double blind, randomized, placebo controlled inter
    The patients will be randomized to one of the 2 treatment groups (12 patients in each group): Group I: intravenous iron carboxymaltose; Group II: intravenous placebo. Group I (intravenous iron): Ferinject will be applied via a short infusion. Patients will receive 15mg/kg of iron as iron carboxymaltose Ferinject® in 250 ml 0.9% NaCl intravenously (time of infusion 20 mins), in a single dose. The maximum dose is limited to 1000mg iron. Group II (intravenous placebo): Intravenous placebo (250 ml 0.9 % NaCl will be administrated in the same manner and time schedule than group I.
