The Claim
High-intensity resistance and impact training increases cortical thickness of the femoral neck by 13.6% in postmenopausal women with low bone mass, and this change is not fully captured by standard bone mineral density scans.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In postmenopausal women with low bone mass, high-intensity resistance and impact training increases the thickness of the outer bone layer in the femoral neck by 13.6%, a change not detected by standard bone density scans.
See the scientific wording
High-intensity resistance and impact training improves cortical thickness of the femoral neck by 13.6% in postmenopausal women with low bone mass, suggesting that mechanical loading may enhance bone structure beyond what is measurable by standard bone mineral density scans.
When bones are pushed and pulled by heavy lifting and jumping, the cells inside the bone detect the force and stop producing a protein that blocks bone growth. This allows other cells to build new bone tissue on the outer shell of the hip bone, making it thicker without changing how dense the bone is.
What the research says
1 studyThis study showed that a safe, supervised high-intensity workout program made the outer shell of the hip bone thicker in older women with weak bones—even though their bone density didn’t change much. Thicker bone shells may help prevent fractures.
