Intervention
Supervised resistance and impact training (LIFTMOR protocol)
Research Observatory
Evidence Update
Current evidence
In LIFTMOR, supervised resistance and impact training improved bone density compared with low-intensity home exercise in selected postmenopausal women with low bone mass. The study did not demonstrate fewer fractures. Its supervision and participant selection are important limits on applying the result outside the trial.
What changed
LIFTMOR supports improved bone density under supervised resistance/impact training, not demonstrated fracture prevention.
How to read these findings
BMD means bone mineral density, a measure of bone mass. Improved density is not the same as demonstrating fewer fractures.
The correction belongs to the original LIFTMOR report; it is not another trial. The findings come from selected women training under supervision, not unrestricted unsupervised exercise.
Accepted limitations and study details
Exact reviewed qualifications are retained below. These details do not add a new accepted claim.
Study interpretation and limitations
- BMD is not fractures; intervention supervision and selected women constrain translation.
- Design: Randomized trial; corrected publication
- Safety: One minor back spasm reported; small selected supervised cohort does not establish broad unsupervised safety.
- Interpretation: Corrected table headings/sign cannot be mistaken for changed BMD endpoint; BMD not fractures.
Why it matters
These findings apply to the studied populations, regimens and outcomes; they do not establish generalized longevity benefit.
Next proof
Larger fracture and adverse-event trials with implementation fidelity.
