The Claim

Supervised high-intensity resistance and impact training does not increase vertebral deformities, cause serious adverse events, or result in frequent minor adverse events in postmenopausal women with osteopenia or osteoporosis, including those with prior vertebral fractures, over an 8-month period.

Description
1 study reviewed
In plain English

In postmenopausal women with low bone density or spinal fractures, supervised high-intensity resistance and impact training over eight months does not cause new spinal deformities, serious injuries, or frequent minor side effects.

See the scientific wording

Supervised high-intensity resistance and impact training is safe in postmenopausal women with osteopenia or osteoporosis, including those with prior vertebral fractures, as demonstrated by no increase in vertebral deformities, no serious adverse events, and only one minor lower back spasm reported over 8 months of training.

Why this might work

When bones are stressed by heavy lifting or jumping, the cells inside the bone detect the force and stop producing a protein that blocks bone growth. This allows bone-building cells to become more active and lay down new bone tissue, making bones stronger and denser without breaking.

    Even women with weak bones and past spine fractures can safely do intense strength and jumping exercises if they’re supervised—this study found no serious injuries, just one tiny muscle spasm, and their bones actually got stronger.
