Age mediates bone mineral density response to exercise

A fantastic researcher, Winters-Stone, has put out a new article on bone mineral density for women with breast cancer.

Previously, they used an impact + resistance training intervention in older breast cancer survivors, and found that while it helped their spine, it didn't help their hips.

In this analysis, the compared the effectiveness of that intervention across age-categories of participants for bone mineral density of the hip. They found that their intervention was successful in the younger women (those closer to 50 years), but those closer to 70 years old saw no benefit.

In their conclusion, they proposed to look at more intense or longer duration exercise programs for older women. They were concerned that the higher intensity work may not be feasible in this subset of the population, but from the results of my study, I think it will be fine, as I had women in their 70s still pumping out the iron.

Exercise effects on hip bone mineral density in older, post-menopausal breast cancer survivors are age dependent.
