Study of the Effects of Muscular Activity on Iron Metabolism - Full Text View

Purpose

The aim of this study is to evaluate the effect of muscular exercise on iron metabolism in healthy volunteers. Fourteen healthy male subjects will have to pedal on an ergocycle for 45 minutes, and urine and blood samples will be collected regularly to measure hemojuvelin, hepcidin, iron and transferrin levels.

Official Title:	Study of the Effects of Muscular Activity on Iron Metabolism: A Pilot Study on Healthy Volunteers

Further study details as provided by Rennes University Hospital:

Primary Outcome Measures:

Pharmacokinetics of urinary hepcidin
Pharmacokinetics of blood hemojuvelin

Secondary Outcome Measures:

Pharmacokinetics of urine and blood iron, transferrin, interleukin-6 (IL-6) and ferritin

Estimated Enrollment:	14
Study Start Date:	September 2006

Detailed Description:

Hemojuvelin has been described as interfering with hepcidin, a key regulator of iron homeostasis. Hemojuvelin is mainly produced by muscle, and the relationship between exercise and iron metabolism can be questioned about.

The aim of this study is to evaluate the effect of muscular exercise on iron metabolism in healthy volunteers. Fourteen healthy male subjects will be investigated at two periods according to a cross-over design after:

45 minutes of exercise on the ergocycle; and
no physical exercise.

Urine and blood samples will be collected at both periods regularly to measure hemojuvelin, hepcidin, iron and transferrin levels.
