Integrated effects of a 12-week intermittent combined exercise on cognitive function, physical performance, and neurophysiological biomarkers in older women.
Abstract
Aging is associated with a progressive decline in both cognitive and physical function, and neuroinflammation and metabolic dysregulation often exacerbate this decline, particularly in older women. This study investigated the effects of a 12-week intermittent combined exercise program on cognitive function, physical performance, and neurophysiological biomarkers in community-dwelling women aged 75 years and older. Forty participants were recruited from a local welfare center and randomly assigned to an exercise group (n=20) or a control group (n=20). The exercise group participated in three supervised sessions per week that integrated aerobic exercise, resistance exercise, functional exercise, and cognitive exercise. Cognitive domains (attention, language, and memory) were assessed using the Seoul Neuropsychological Screening Test-II. Physical function was assessed using the Geriatric Physical Fitness Test (chair stand, arm flexion, grip strength, and 6-min walk). Blood samples were analyzed to measure serum brain-derived neurotrophic factor (BDNF), interleukin (IL-6), tumor necrosis factor (TNF)-α, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG).

Research summary
The paper claims that a 12-week intermittent combined exercise program improves cognitive function, physical performance, and neurophysiological biomarkers in older women. This study addresses the decline in cognitive and physical function associated with aging, which is relevant to understanding and potentially mitigating age-related decline.
