A Little Exercise Goes a Long Way

Even a little exercise can make a big impact on your bone health.

A new study shows that physical activity in premenopausal women reduces the hormone sclerostin, which inhibits bone formation.

A total of 1,235 randomly selected premenopausal women were involved in this cross-sectional study. All women were medically examined and measurements were taken for bone mineral density, bone turnover markers, serum sclerostin, and IGF-1.

At the conclusion of the study, scientists discovered that those women who had more than two hours of physical activity per week had significantly lower levels of serum sclerostin, but had higher levels of IGF-1 (a positive effector of bone health) than those women who had less than two hours of physical activity per week.
