This can have repercussions on their health : osteoporosis but also heart diseases because of bad vascular function.
A this study has determined if folic acid supplementation improves endothelial vascular function in runners.
Ten amenorrheic and 10 eumenorrheic women runners were treated with folic acid (10 mg/d) for 4 weeks. Brachial artery flow-mediated dilation was measured before and after folic acid supplementation.
Brachial artery flow-mediated dilation, an indicator of vascular endothelial function, improves in amenorrheic female runners after short-term supplementation with folic acid. There were no changes in eumenorrheic women.
As a lot of women athletes are amenorrheic, acid folic supplementation may be an easy and cheap way to protect them against some heart diseases.
