Physical activity and its role in the prevention of osteoporosis in women

Consistent evidence shows that weight-bearing exercise during youth contributes to increased peak bone mass and is important for the maintenance of bone health and minimising the rate of bone loss later in life.

The two key factors in preventing osteoporosis are to increase peak bone mass that occurs prior to 20-30 years of age; and decrease the rate of bone loss that occurs after the age of 40-50 years.

This research suggests that peak bone mineral density (BMD) may be the single most important factor in delaying the development of the disease.
