【Abstract】 By referring to the related literature, the authors discuss the effect of exercises on bone mineral density and emphasize the effect of sex hormone changes induced by exercises on BMD. The results show that exercises with proper loads can increase BMD, but excessive exercises can result in osteoporosis. Besides this, the lower level of sex hormone induced by exercises is the main cause that leads to lower BMD of female athletes with menstrual irregularities.更多还原
