BHS4 - Bone/Muscle Changes Following Hip Fracture in Older White Women

The major goals of this study are: 1. To conduct an intervention development study to evaluate the feasibility of implementing an exercise intervention for reduction losses in bone mineral density, muscle mass, and strength, and clinically relevant aspects of functioning following a hip fracture, and to obtain preliminary tests of the effective ness of these interventions. 2. To evaluate the effect of home-based exercise intervention on bone metabolism. 3. To evaluate the effects of hip fracture on bone metabolism. 4. To evaluate the effects of exercise and hip fracture on hormonal regulators. 5. To evaluate the association between markers of bone metabolism hormone regulators, and BMD. 6. To separate out the effects of hip fracture on bone turnover from those of aging in persons with low bone mineral density.
