Skeletal Muscle Power: A Critical Determinant of Physical Functioning in Older Adults
Open accessAbstract
In Brief Muscle power declines earlier and more precipitously with advancing age compared with muscle strength. Peak muscle power also has emerged as an important predictor of functional limitations in older adults. Our current working hypothesis is focused on examining lower extremity muscle power as a more discriminant variable for understanding the relationships between impairments, functional limitations, and resultant disability with aging. This article emphasizes that skeletal muscle power impairments are critical physiological determinants of physical functioning and mobility limitations among older adults.

“Improvements in knee and leg extensor muscle power after high velocity power training were approximately twofold greater compared to gains in muscle power as a result of strength training.”

What the sources say
- Disputedcites [25] sourceExperimental — accuracy not yet measured
The Abstract (page unavailable) identifies this as a cross-sectional study of 34 older women measuring ankle-flexor power, not a training comparison in 45 older adults. It reports associations with functional performance, not approximately twofold greater gains after high-velocity training than after strength training. (LLM, conf=0.88)

The Discussion reports that Earles et al. found a 22% increase in leg-press power after 12 weeks, not the claimed 50–141%. It does describe a significant power difference between the training and walking groups, but that does not support the claimed magnitude. (LLM, conf=0.88)

The paper’s introductory passage says power is highly related to functional-task performance and that loss of anaerobic power can limit older adults’ activities. The Subjects and Procedures section also links low leg-extensor power with low physical function. These passages support the claim as a broad statement about prediction, though the study did not establish that changes in peak power predict changes in function. (LLM, conf=0.84)

The Methods and Table 2 report adjusted regression models showing significant associations of leg power with SPPB scores and habitual gait speed. But the Discussion describes the analysis as cross-sectional: it did not assess changes in leg power or establish that changes were associated with clinically meaningful differences in those outcomes. The leg-power models were also separate from the strength models, rather than adjusted for strength. (LLM, conf=0.88)

The Protocol and Instrumentation sections describe multiple leg-press attempts at two resistance levels using pneumatic equipment. But the Data Analysis section compares participant groups, not multiple-attempt with single-attempt protocols; our copy reports no reliability comparison or finding that one protocol yields higher performance. It therefore does not support the claimed systematic evaluation or its comparative result. (LLM, conf=0.88)

“When muscle power is assessed across a range of external resistances (40%–90% of one repetition maximum (1RM)), peak muscle power is typically yielded at approximately 70% of the 1RM while maximal contraction velocity typically occurs at the lowest external resistance (40% of 1RM)(11, 15, 18).”

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.
A language model drew the claims from the paper on 2026-09-28, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-09-28 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
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.
