Abstract

The purpose of this study was to investigate and add reference data about the musculoskeletal system in women. The mechanography system of the Leonardo™ platform (Novotec, Germany) was used to measure parameters of movement (velocity, force, power) in 176 healthy Greek women aged 20-79 years, separated according to age decade in six groups: group 1 (n = 12), 20-29 years; group 2 (n = 14), 30-39 years; group 3 (n = 33), 40-49 years; group 4 (n = 59), 50-59 years including 21 postmenopausal; group 5 (n = 31), 60-69 years including 12 postmenopausal; and group 6 (n = 27), 70-79 years all postmenopausal. This system measures forces applied to the plate over time, calculates through acceleration the vertical velocity of center of gravity and using force and velocity it calculates power of vertical movements. All women performed a counter-movement jump (brief squat before the jump) with freely moving arms. Weight was recorded on the platform before the jump and height was measured with a wall-mounted ruler. Body weight and body mass index were gradually increased; on the contrary height and all movement parameters except force (velocity, power) were statistically decreased during aging and after menopause.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Other age-, sex-, or ethnicity-related differences between participants were not accounted for, although they are important determinants of the decrease in muscle power with increasing age.

    “Other age- (young old versus oldest old), sex-, or ethnicity-related differences between participants were also not accounted for, but are important determinants of the decrease in muscle power with increasing age [11, 13, 44].”

    From Effectiveness of power training compared to strength training in older adults: a systematic review and meta-analysis (2022) · cites this paper as [13]

    The Results and Discussion (page unavailable) document declining muscle power with age in women and an accelerated postmenopausal decline. The Discussion also reports an age–power correlation for both sexes from another study, but this paper does not establish ethnicity-related differences or show that all three listed characteristics determine the decline. It does not address whether those differences were accounted for among the citing study’s participants. (LLM, conf=0.84)

    Experimental — accuracy not yet measured

  • The annual decline in muscle power is larger than the annual decline in muscle strength in older adults.

    “Several studies have revealed that the annual decline in muscle power is larger than the annual decline in muscle strength in older adults [10–16].”

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.
