The Claim
Supervised high-intensity resistance and impact training performed twice weekly for 8 months increases lumbar spine bone mineral density by 2.9% and femoral neck bone mineral density by 0.3% in postmenopausal women with osteopenia or osteoporosis, while a low-intensity home-based program results in a 1.2% decrease in lumbar spine and 1.9% decrease in femoral neck bone mineral density.
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 density, performing supervised high-intensity resistance and impact exercises twice a week for eight months increases bone density in the spine and hip, while a low-intensity home program reduces bone density in these areas.
See the scientific wording
Supervised high-intensity resistance and impact training performed twice weekly for 8 months increases lumbar spine bone mineral density by 2.9% and femoral neck bone mineral density by 0.3% in postmenopausal women with osteopenia or osteoporosis, while a low-intensity home-based program results in a 1.2% decrease in lumbar spine and 1.9% decrease in femoral neck bone mineral density, demonstrating that targeted mechanical loading can improve skeletal density in this high-risk population.
When bones are stressed by heavy lifting and jumping, the cells inside the bone detect the force and reduce a protein that normally blocks bone growth. This allows signals to activate bone-building cells, which lay down new bone tissue, making the bone denser and stronger.
What the research says
1 studyWhen older women with weak bones did supervised heavy lifting and jumping exercises twice a week for 8 months, their spine and hip bones got stronger. Women who did easy home exercises instead lost bone density. This shows that tough, guided workouts can help protect bones.
