Long-term structured physical activity,
does it really help with Prevention of major mobility disability, inability to walk 400 m within 15 minutes?
research showsThe grade is B with 70 points. LIFE randomized 1,635 participants to physical activity, 818, or health education, 817. Over a mean 2.6 years, first major mobility disability occurred in 246/818 (30.1%) versus 290/817 (35.5%), HR 0.82 (95% CI 0.69-0.98). The ability to complete a 400-m walk is a patient-centered performance outcome, not a laboratory surrogate.
ads claimThis was not generic advice to move more. It was a long-term program combining center and home sessions with walking, resistance, flexibility, and balance work.
Useful facts when choosing a product
- Participants could walk 400 m at baseline but were sedentary and functionally limited.
- The program centered on walking plus resistance, flexibility, and balance training.
- Health education with upper-extremity stretching was the active control.

What the research actually shows
Eight US centers used a computer-generated allocation sequence, masked walking assessors, randomized-group analysis, and a registered primary outcome matching the paper. Participant masking was impossible because of the intervention, and masked assessment, assigned-group analysis, and registry concordance were present; however, there was no evidence that participants remained masked, so the evidentiary requirements for B0 were not met. Verdicts 1723 and 1773 concern intermittent claudication and colon-cancer recurrence, different populations and outcomes.
Why this is classified as B (70)
A large publicly funded trial improved a patient-centered mobility outcome, but absent independent replication and insufficient support for B0 give B with 70 points.
Counterpoint. The result applies to functionally limited but ambulatory older adults and requires individualized safety screening.
Rejudgment record. Cross-check applied — Cross-checked the registered primary outcome, allocation, assessor masking, assigned-group analysis, funding, and absence of participant masking against the JAMA article and NCT01072500
| Endpoint | P | Symptom or function itself is the target - including patient reports and performance tests |
| Replication | R1 | Single confirmatory trial |
| Independence | I2 | Decisive evidence is publicly or non-profit funded |
| Effect size | E+ | Meets the clinically important threshold |
Stored derived and displayed grades match; this is not a current recalculation or validity check (B).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Structured physical activity reduces major mobility disability | B | The HR was 0.82 (0.69-0.98). |
