Abstract

Background: Physical activity ( PA ) reduces the rate of mobility disability, compared with health education ( HE ), in at risk older adults. It is important to understand aspects of performance contributing to this benefit. Objective: To evaluate intervention effects on tertiary physical performance outcomes. Design: The Lifestyle Interventions and Independence for Elders ( LIFE ) was a multi‐centered, single‐blind randomized trial of older adults. Setting: Eight field centers throughout the United States. Participants: 1635 adults aged 78.9 ± 5.2 years, 67.2% women at risk for mobility disability (Short Physical Performance Battery [SPPB] <10). Interventions: Moderate PA including walking, resistance and balance training compared with HE consisting of topics relevant to older adults. Outcomes: Grip strength, SPPB score and its components (balance, 4 m gait speed, and chair‐stands), as well as 400 m walking speed. Results: Total SPPB score was higher in PA versus HE across all follow‐up times (overall P = .04) as was the chair‐stand component (overall P < .001). No intervention effects were observed for balance (overall P = .12), 4 m gait speed (overall P = .78), or grip strength (overall P = .62). However, 400 m walking speed was faster in PA versus HE group (overall P =<.001). In separate models, 29% of the rate reduction of major mobility disability in the PA versus HE group was explained by change in SPPB score, while 39% was explained by change in the chair stand component. Conclusion: Lower extremity performance ( SPPB ) was significantly higher in the PA compared with HE group. Changes in chair‐stand score explained a considerable portion of the effect of PA on the reduction of major mobility disability–consistent with the idea that preserving muscle strength/power may be important for the prevention of major mobility disability.

  • In the multicenter LIFE study, improvements in muscle strength and power were largely responsible for the reduction of mobility disability in the physical activity group.

    “The multicenter LIFE study showed that improvements in muscle strength and power, as seen in the improvements in chair stands, is largely responsible for the reduction of mobility disability in the physical activity group.58”

    From Comparison of Power Training vs Traditional Strength Training on Physical Function in Older Adults: A Systematic Review and Meta-analysis (2022) · cites this paper as [58]

    The Discussion says the lower rate of major mobility disability in the physical activity group was largely attributable to improved chair-stand performance. But chair stands were a surrogate for lower-extremity strength and power; the paper did not measure those directly and says muscle function only “appears” to be a mechanism, with other factors possibly contributing. The claim states that inferred mechanism more definitively than the source does. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
