Abstract

BACKGROUND: The performance of daily tasks, such as stair climbing or lifting an object, requires both muscle strength and power. Age-associated reductions in strength and power can affect an older adult's ability to complete daily tasks such as stair climbing and lifting a child. METHODS: The purposes of this study were to determine whether power training was more efficacious than strength training for improving whole-body physical function in older adults and to examine the relationship between changes in anaerobic power and muscle strength and changes in physical function. Thirty-nine men and women (mean age +/- SD = 72.5 +/- 6.3 years) with below-average leg extensor power were randomly assigned to control (C, n = 15), strength-training (ST, n = 13) or power-training (PT, n = 11) groups. The ST and PT groups met 3 days per week for 16 weeks; the C group maintained usual activity and attended three lectures during the course of the study. Primary outcome measures included the Continuous Scale Physical Functional Performance test, maximal strength, and anaerobic power. RESULTS: After baseline was controlled for, the Continuous Scale Physical Functional Performance test total score was significantly greater for the PT group than for the ST (p =.033) and C (p =.016) groups. Maximal strength was significantly greater for the ST group than for the C group (p =.015) after the intervention. There was no significant difference between groups for peak anaerobic power. CONCLUSIONS: Power training was more effective than strength training for improving physical function in community-dwelling older adults.

  • In elderly community-dwelling women with self-reported disability, peak muscle power was superior to muscle strength and aerobic capacity in determining functional status and independently predicted functional dependency after accounting for neuropsychological and health status indicators.

    “Peak muscle power (r = 0.47) was superior to muscle strength (r = 0.43) and aerobic capacity (r = 0.40) in determining functional status and independently predicted functional dependency even after accounting for additional neuropsychological and health status indicators.”

    Experimental — accuracy not yet measured

  • Previous reviews included studies using plyometric exercises, such as depth jumps and countermovement jumps.

    “However, those reviews included studies using plyometric exercises, such as depth jumps and countermovement jumps.17,18”

    From Comparison of Power Training vs Traditional Strength Training on Physical Function in Older Adults: A Systematic Review and Meta-analysis (2022) · cites this paper as [17]

    The Subjects and Procedures section (page not provided) describes jump squats in this study’s power-training program, supporting it as an example of a study using a jumping exercise. It does not describe depth jumps or countermovement jumps, or establish that the study was included in the reviews mentioned by the citing sentence. (LLM, conf=0.85)

    Experimental — accuracy not yet measured

  • The effects of power training on physical functioning appeared even larger than after strength training and endurance training.

    “The effects appeared even larger than after strength training and endurance training [3, 4, 7, 8, 17–20].”

    From Effectiveness of power training compared to strength training in older adults: a systematic review and meta-analysis (2022) · cites this paper as [7]

    The Physical Function section reports significantly higher whole-body physical-function scores after power training than after strength training. The Discussion mentions an earlier combined strength-and-endurance program, but this study did not compare power training with endurance training, so it does not establish that the effects were larger than after endurance training. (LLM, conf=0.86)

    Experimental — accuracy not yet measured

  • Training specifically aimed at increasing muscle power can improve the ability to generate high power output even in older adults.

    “Several studies have shown that training specifically aimed at increasing muscle power can improve the ability to generate high power output even in older adults [7, 17, 18].”

    From Effectiveness of power training compared to strength training in older adults: a systematic review and meta-analysis (2022) · cites this paper as [7]

    The introduction says older adults who train for muscle power are more powerful than those who do not, and the Discussion reports that other researchers found improvements after power training. But this paper’s own trial found no significant improvement in anaerobic power, so it does not itself demonstrate the claimed increase in power output. (LLM, conf=0.86)

    Experimental — accuracy not yet measured

  • Peak muscle power is an important predictor of functional limitations in older adults.

    “Peak muscle power has also emerged as an important predictor of functional limitations in older adults.”

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.
