Active young women need calcium, vitamin D

The International News—Pakistan—May 10, 2010

Calcium and vitamin D supplements may do more than strengthen bones in older women. These vital nutrients may also help younger, active women reduce their risk of stress fractures.

To illustrate that point, many bone health experts refer to a recent study of more than 5,200 female U.S. Navy recruits that found that women who didnít take additional calcium and vitamin D were about 25 percent more likely to suffer a stress fracture than women who took the vitamin and mineral combination.

ďThe most common time for a stress fracture is when youíre increasing your exercise levels ó when youíre going from doing nothing to doing a whole lot. Itís too much, too fast, and the bone canít handle it,Ē explained Dr. Sabrina Strickland, an orthopedic surgeon who specializes in sports medicine at Hospital for Special Surgery in New York City.

ďBefore you embark on any sort of exercise regimen, take calcium and vitamin D supplements to reduce your chances of a stress fracture,Ē she advised. Stress fractures occur when muscles become tired and canít absorb shock properly. That force is then transferred to the bone instead. After time, that added shock can cause a tiny crack in the bone. Women are more likely to suffer stress fractures, particularly women involved in just one particular sport, such as running, tennis, gymnastics or basketball.
