Bone Mineral Density and Body Composition of Adult Premenopausal Women with Three Levels of Physical Activity

Weight-bearing and resistance physical activities are recommended for osteoporosis prevention, but it is unclear whether an intensity level above current recommendations has a positive effect on adult premenopausal women. Body composition and bone mineral density (BMD) by DXA were compared in three...

Bone mineral content and non-fat soft tissue mass were higher and fat mass was lower in the Sport Team group than in the other groups.
