Summary:
Lower-body muscle mass is a better predictor of bone mineral density at the hip than either strength or level of physical activity, according to a study in J. Clinical Densitometry
Exercise has been shown to reduce the risk of hip fracture by increasing bone mineral density (BMD) and improving core strength and balance
Lower body muscle mass was related to hip BMD in a large sample of men and women over 50
Conclusion: Exercise programs for people over 50 should target improving both strength and lower body muscle mass, while muscle mass can be used to predict risk of osteoporosis
