Muscle power of the ankle flexors predicts functional performance in community-dwelling older women.
Open accessAbstract
OBJECTIVES: To test the hypothesis that peak power of the ankle flexors is related to physical functioning in older women with functional limitations. DESIGN: A cross‐sectional study. SETTING: University‐based human physiology laboratory. PARTICIPANTS: Thirty‐four older women (75.4 ± 5.1 years, 67.8 ± 11.3 kg, body mass index 27.4 ± 4.5) with self‐reported functional limitations. MEASUREMENTS: Plantarflexion (PF) and dorsiflexion (DF) peak power and isometric strength with physical performance (stair climb time, repeated chair rise time, maximal and habitual gait velocity) were determined. An isokinetic dynamometer was used to measure isometric strength, isokinetic peak torque and power of PF and DF at five angular velocities (30°, 60°, 90°, 120°, and 180°·sec −1 ), and isometric strength. RESULTS: Peak torque for both PF and DF declined with increasing velocity of movement (PF: P < .0001; DF: P < .0001), whereas peak power increased with increasing velocity up to 120°·sec −1 . The strongest univariate associations were found between chair rise time and DF peak power ( r = 0.50; P < .002), stair climb time and DF peak power ( r = 0.49; P < .003), habitual gait velocity and PF isometric strength ( r = 0.53; P < .001), and maximal gait and PF isometric strength ( r = 0.47; P < .005). Multivariate regression analysis revealed that DF and PF peak power along with the physical functioning and general health scores from the Medical Outcomes Study Short Form were independent predictors of chair and stair climb performance. CONCLUSION: These data suggest that ankle muscle power together with self‐reported measures of health and physical functioning are essential components of functional mobility in older women with functional limitations.

In the citing paper
“However, recent randomized trials designed to maximize muscle power output have generally demonstrated that high velocity power training is feasible, well tolerated, and can effectively improve lower extremity muscle power in healthy older men and women, older women with self-reported disability (18, 25), older adults with mobility limitations (30) and in older women aged over 80 years(12).”

“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.”

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.
