Abstract

Objective

To determine if folic acid supplementation improves vascular function (brachial artery flow-mediated dilation [FMD]) in professional dancers with known endothelial dysfunction.

Design

Prospective cross-sectional study.

Setting

Academic institution in the Midwestern United States.

Subjects

Twenty-two professional ballet dancers volunteered for this study.

Main Outcome Measures

Subjects completed a 3-day food record to determine caloric and micronutrient intake. Menstrual status was determined by interview and questionnaire. Endothelial function was determined as flow-induced vasodilation measured by high-frequency ultrasound of the brachial artery. A change in brachial diameter of

Results

Sixty-four percent of dancers (n = 14) had abnormal brachial artery FMD (P< .0001).

Conclusions

This study reveals that vascular endothelial function improves in dancers after supplementation with folic acid (10 mg/day) for at least 4 weeks. This finding may have clinically important implications for future cardiovascular disease risk prevention.
