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.
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.
