Effect of Physical Activity versus Health Education on Physical Function, Grip Strength and Mobility
Open accessAbstract
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.

“Slow gait speed in older adults is associated with an increased risk for disability,(1,2) institutionalization(1) and mortality.(1,3) Poor muscle function (strength/power) is an important risk factor for slowed gait and is also associated with increased risk of disability and death.”

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.
