Bone mineral content of junior competitive weightlifters.

It is suggested that practicing various sports can increase the bone mineral content (BMC). However, we were unable to find any reports indicating BMC changes in weightlifting, a sport which involves both extremities and spine and increases muscle mass as well. Therefore, we thought that it might be of interest to measure BMC in junior competitive weightlifters.

Bone mineral loss related to menstrual history.

We measured the bone mineral content (BMC) of the forearm in 173 normal postmenopausal women. We also examined the relation between BMC and the chronologic age, the number of years elapsed since menopause, and the total number of menstrual cycles during the reproductive years. BMC had a better linear relation to the total number of menstrual cycles than with the years elapsed since menopause or with chronologic age.
