Abstract

Objective: To determine the associations between muscle-strengthening activity (MSA) and cognitive function among middle-aged and older adults.

Methods: This cross-sectional study included 2973 participants aged ≥55 in the Cooper Center Longitudinal Study. Participants self-reported leisure-time physical activity. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA). The associations of reported MSA frequency (0-1 vs. ≥2 sessions/week) and volume (zero, low: ≤250, medium: 250-420, high: >420 MET minutes/week) with mild cognitive impairment (MCI, defined as MoCA<26) and MoCA total score were examined using logistic and linear regression.

Results: Individuals who participated in ≥2 MSA sessions/week had a significantly higher MoCA total score. Participants with medium MSA volume were significantly associated with lower odds of being classified as MCI and associated with a higher MoCA total score than those with zero volume.

Conclusions: Engaging in MSA is associated with cognitive health among middle-aged and older adults independent of aerobic exercise.

目的：确定中老年人肌肉锻炼活动（MSA）与认知功能之间的关系：确定中老年人肌肉锻炼活动（MSA）与认知功能之间的关系：这项横断面研究包括库珀中心纵向研究中 2973 名年龄≥55 岁的参与者。参与者自我报告了业余时间的体育锻炼情况。认知功能采用蒙特利尔认知评估（MoCA）进行评估。报告的 MSA 频率（0-1 次与≥2 次/周）和运动量（零、低：≤250、中：250-420、高：>420 MET 分钟/周）与轻度认知障碍（MCI，定义为 MoCAResults：每周参加≥2 次 MSA 活动的人的 MoCA 总分明显更高。MSA运动量中等的参与者被归类为MCI的几率明显低于运动量为零的参与者，MoCA总分也明显高于运动量为零的参与者：参与 MSA 与中老年人的认知健康有关，与有氧运动无关。

期刊介绍： The Journal of Aging and Health is an interdisciplinary forum for the presentation of research findings and scholarly exchange in the area of aging and health. Manuscripts are sought that deal with social and behavioral factors related to health and aging. Disciplines represented include the behavioral and social sciences, public health, epidemiology, demography, health services research, nursing, social work, medicine, and related disciplines. Although preference is given to manuscripts presenting the findings of original research, review and methodological pieces will also be considered.
