Cycling could be good for heart and muscles, but bad for bones. Cyclists tend to have osteopenia or lower-than-normal bone density.
"You would think that cyclists are very healthy because they spend all those
hours training," says Pam Hinton, associate professor of nutritional sciences at
the University of Missouri-Columbia and coauthor of the study accepted for
publication in the journal id=KonaLink0 onmouseover=adlinkMouseOver(event,this,0);

The study tested the bone mineral density of 27 cyclists and 16 runners ages 20
to 59 who had engaged in their sport a minimum of six hours a week for at least
two years.
men may not be as much at risk for low bone density as women -- especially
postmenopausal women.
