In the authors' words
“Trabecular bone-mineral density (BMD) of the lumbar spine (L1-L3), measured by computed tomography, increased by 0.5% in exercising women (n = 18) and decreased by 7.0% in sedentary women (n = 18; P = 0.02).”

How to read this. Each line is one study, summarised in plain language from its PubMed abstract, with the authors' own sentence underneath on the study page. A count of studies is not a verdict: trials differ in size, length and quality, and a result in one group of women may not hold in another. Nothing here is medical advice.
Summaries are generated, then checked by machine against the abstract they came from; any summary that could not be matched word for word was left out. Our clinical lead is reviewing the summaries topic by topic, and this note will change when that is done. Corpus last refreshed 2026-11-03. Spotted a mistake? Tell us and we will fix the summary or remove the study.

- A meta-analysis of RCTs found that ground and joint reaction exercise of at least 24 weeks produced small but significant improvements in femoral neck and lumbar spine bone density in postmenopausal women.
- A meta-analysis of eight trials in sedentary postmenopausal women found walking programmes did not significantly change spine bone density but showed a positive effect at the femoral neck.
- A meta-analysis of 18 randomized trials found aerobics, weight-bearing and resistance exercise increased spine bone density in postmenopausal women, and walking also increased hip bone density.
- A meta-analysis of 10 trials found walking alone did not significantly change spine, radius or whole body bone density, but improved femoral neck density after more than 6 months.
