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 16 trials in older postmenopausal women found whole-body vibration raised lumbar spine bone density while aerobic exercise lowered it, with no overall effect on femoral neck density.
- A meta-analysis of 53 studies in women over 60 found exercise training increased bone mineral density at the femoral neck, lumbar spine and trochanter, with no change in total hip or total body.
- A meta-analysis of six RCTs in inactive postmenopausal women found combined exercise and reduced calorie diet, lasting 16 to 52 weeks, lowered estrogen and testosterone levels more than exercise alone.
