Abstract

OBJECTIVE: To determine normative values for weight-bearing, countermovement leg extension ("jump") tests in the oldest men and characteristics of those not completing vs. completing tests. DESIGN: 2014-16 cross-sectional exam. SETTING: Six U.S. sites from the Osteoporotic Fractures in Men (MrOS) Study. PARTICIPANTS: Community-dwelling men (N=1,841) aged 84.5±4.2 (range: 77-101) years. INTERVENTIONS: N/A. MEASUREMENTS: Jump tests on a force plate measured lower-extremity muscle peak power/kg, velocity and force/kg at peak power, with normative values for 5-year age groups and by limitations in moderate-intensity activities of daily living (ADLs) and climbing several flights of stairs. RESULTS: Jump completion was 68.9% (N=1,268/1,841) and 98% (1,242/1,268) had ≥1 analyzable trial/participant. Exclusions primarily were due to poor mobility and/or balance: 24.8% (456/1,841) prior to and 6.4% (N=117/1,841) after attempting testing. Peak power was 20.8±5.3 W/kg, with 1.2±0.3 m/s for velocity, and 16.7±1.9 N/kg for force at peak power. Each 5-year age group >80 years had subsequently 10% lower power/kg, with 30% lower power/kg at >90 vs. ≤80 years (all p<0.05). Velocity and force/kg at peak power were 24% and 9% lower respectively, at >90 vs. ≤80 years (all p<0.05). Limitations in both moderate ADLs and climbing several flights of stairs were associated with 16% lower age-adjusted power/kg, equivalent to 5-10 years of aging, with 11% and 6% lower age-adjusted velocity and force/kg respectively, vs. those without limitation (all p<0.05). Men not completing vs. completing jumps had older age, higher BMI, lower physical activity, more comorbidities, worse cognition, more IADLs/ADLs and more falls in the past year (all p<0.05). Post-jump pain occurred in 4.6% (58/1,268), with 2 participants stopping testing due to pain. Only 24/1,242 (2%) had all trials/participant without flight (i.e., inability to lift feet), with 323/1,242 having ≥1 trial/participant without flight (total of 28%). No serious adverse safety events (e.g., injury) occurred. CONCLUSIONS: A multicenter cohort of oldest men with a range of function had higher declines in jump power/kg and velocity vs. force/kg across each 5-year age group >80 years. Future research should examine age- and functional-related declines in jump measures related to physical performance decline, falls, fractures, and disability.

  • In daily activities, the ability to move with sufficiently large speed is more often the limiting factor than the ability to produce a sufficiently large moment.

    “in daily activities, such as getting up from a chair, the ability to move with a sufficiently large speed (emphasizing muscle power) is more often the limitating factor than the ability to produce a sufficiently large moment [10, 17].”

    From Effectiveness of power training compared to strength training in older adults: a systematic review and meta-analysis (2022) · cites this paper as [10]

    The Results (page unavailable) show that, among men aged 77–101 reporting both moderate-activity and stair-climbing limitations, jump velocity was 11% lower and force at peak power was 6% lower than in men without those limitations. This supports an association between lower velocity and daily-activity limitations, but the paper does not establish that speed is more often the limiting factor than the ability to produce joint moment, including when rising from a chair.

  • 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].”

    From Effectiveness of power training compared to strength training in older adults: a systematic review and meta-analysis (2022) · cites this paper as [10]

    The Introduction says age-related muscle power decline is more marked than strength decline. The Discussion reports 10% lower power versus 3% lower force across successive five-year age groups, but these are cross-sectional differences among men aged 77–101, not measured annual declines in older adults generally. Page numbers were not provided in our copy. (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.
