What does this research mean for the field?

In postmenopausal women, total lean mass and body weight are positively associated with bone mineral density and lower fracture risk, independent of specific exercise modalities. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To evaluate differences in bone mineral density, trabecular bone score, and fracture risk across different exercise modalities and determine their relationship with body composition in postmenopausal women.

Overview

Cross-sectional study reveals lean mass strongly predicts bone mineral density in postmenopausal women, highlighting muscle preservation over exercise modality for fracture prevention.

Key Points

To evaluate differences in bone mineral density, trabecular bone score, and fracture risk across different exercise modalities and determine their relationship with body composition in postmenopausal women.
Cross-sectional study evaluated 58 postmenopausal women categorized into four activity groups: sedentary, runners, swimmers, and high-intensity exercisers.
Dual-energy X-ray absorptiometry (DXA) measured total and regional body composition and bone mineral density (BMD), alongside trabecular bone score (TBS) and fracture risk assessment tool (FRAX) calculations.
ANCOVA with Bonferroni post hoc testing and linear regression models were performed while adjusting for lean mass, years postmenopause, and past exercise history.
No significant differences were observed between exercise groups and sedentary controls for total or regional lean mass, BMD, TBS, or FRAX scores.
Total lean mass and body weight positively associated with total, arm, and leg BMD, as well as total bone mineral content across all participants (all p < 0.05).
Total lean mass was positively associated with trunk BMD (p = 0.04) and negatively associated with FRAX (p = 0.01) and TBS-adjusted FRAX (p = 0.03).
