(Ivanhoe Newswire) – Doctors have issued a warning for some female
athletes. Unhealthy eating habits observed in ballerinas and runners can
lead to health complications with long-lasting consequences.
When females don’t eat enough to offset the energy they spend, they can stop
menstruating (amenorrhea), putting them at risk for cardiovascular and bone
density deficits typical of older, postmenopausal women.
Two separate studies examined the effects of amenorrhea on female athletes.
The first focused on ballerinas, most of whom were in a calorie deficit.
Twenty-seven percent were currently amenorrheic. Arterial ultrasound showed
64 percent of the dancers had abnormal artery dilation in response to blood
flow.
A second study examined the effects of high-dose (10 milligrams/day) folic
acid supplements in amenorrheic runners. Researchers found four to six weeks
of supplementation resulted in improved vascular function among study
participants. Not only did this reduce the women’s cardiovascular risks, but
participants also reported improved athletic performance.
