摘要

背景:腰部伸肌(LEMs)对老年人的身体姿势和身体功能起着重要作用。随着年龄的增长,腰部伸肌力量比四肢肌肉力量下降得更快,因此应该对腰部伸肌力量进行评估,以帮助老年人健康地步入老年。本研究调查了社区老年人的腰伸肌力量与身体表现之间的关系:这项脊柱肌肉疏松症前瞻性队列观察研究(SarcoSpine)在一个中心进行。连续有 110 人完成了基线调查,包括常规肌肉疏松指数、腰椎三维磁共振成像、等动腰椎伸肌力量和体能测试(短期体能测试、Berg 平衡量表和背部表现量表 [BPS])。结果发现,在传统的肌肉松弛症中,腰伸肌力是最重要的指标之一:结果:在常规的肌肉疏松指数中,步速与男性和女性的短期体能测试结果和伯格平衡量表评分有显著相关性。男性和女性的手握力与 BPS 评分有明显相关性。在多变量线性回归中,年龄(β = -2.12,p < .01)和 BPS 评分(β = -3.54,p = .01,R2 = .29)是 LEM 力量的独立指标:结论:我们的研究结果表明,老年妇女的 LEM 力量与 BPS 评分之间存在密切联系。结论:我们的研究结果表明,老年妇女的 LEM 力量与 BPS 评分之间存在很大的关联,因此需要采取旨在提高 LEM 力量的针对性干预措施,以提高老年人群的体能表现。

Lumbar Extensor Muscle Strength and Physical Performance in Community-Dwelling Older Adults: Findings From SarcoSpine Cohort.

Background: The lumbar extensor muscles (LEMs) play an important role in body posture and physical function in older adults. Because lumbar extensor strength decreases more rapidly than limb muscle strength with age, it should be evaluated to aid healthy aging. This study investigated the association between LEM strength and physical performance in community-dwelling older adults.

Methods: This prospective observational cohort study of spinal sarcopenia (SarcoSpine) was conducted at a single center. One hundred and ten consecutive individuals who completed the baseline survey, including conventional sarcopenic indices, lumbar spine three-dimensional magnetic resonance imaging, isokinetic lumbar extensor strength, and physical performance tests (Short Physical Performance Battery, Berg Balance Scale, and Back Performance Scale [BPS]), were enrolled. A multivariate linear regression analysis was performed to determine the variables for evaluating their association with LEM strength.

Results: Among the conventional sarcopenic indices, gait speed was significantly correlated with Short Physical Performance Battery results and Berg Balance Scale score in men and women. Handgrip strength was significantly correlated with the BPS score for both sexes. In the multivariable linear regression, age (β = -2.12, p < .01) and BPS score (β = -3.54, p = .01, R2 = .29) were independent indicators of LEM strength.

Conclusions: Our findings reveal the substantial association between LEM strength and BPS score in older women. The targeted intervention aimed at improving the LEMs strength would be needed to enhance physical performance in the aging population.

期刊介绍: The Journal of Aging and Physical Activity (JAPA) is a multidisciplinary journal that publishes peer-reviewed original research reports, scholarly reviews, and professional-application articles on the relationship between physical activity and the aging process. The journal encourages the submission of articles that can contribute to an understanding of (a) the impact of physical activity on physiological, psychological, and social aspects of older adults and (b) the effect of advancing age or the aging process on physical activity among older adults. In addition to publishing research reports and reviews, JAPA publishes articles that examine the development, implementation, and evaluation of physical activity programs among older adults. Articles from the biological, behavioral, and social sciences, as well as from fields such as medicine, clinical psychology, physical and recreational therapy, health, physical education, and recreation, are appropriate for the journal. Studies using animal models do not fit within our mission statement and should be submitted elsewhere.
