Recently, interest has been forcused on the increasing incidence of bone fracture due to low bone mineral density (BMD) in some sportswomen. Therefore the present study attempted to elucidate important factors associated with an increase or decrease of BMD in sportswomen.
The results obtained were as follows;
(1) Ball games appeared to be the most desirable main sports. Also it appeared necessary to increase lean body mass (weight) by maintaining a higher activity of daily living (ADL) index.
(2) There were no clear nutritional factors that had a beneficial influence for increasing the BMD.
These results suggest that sufficient exercise, at least, is necessary in order to increase BMD.
