Exercise in Perimenopause to Improve Cognitive Health

1. PURPOSE: To determine if progressive resistance training (PRT) can improve cognitive outcomes compared to balance, flexibility, and tone (BAT) exercises in perimenopausal females aged 40-55 years with subjective cognitive complaints. 2. HYPOTHESIS: At the end of the intervention, PRT will result in an increase in words recalled during the RAVLT 20-minute delay vs no improve in BAT. 3. JUSTIFICATION: The menopause transition (MT) negatively impacts cognitive function and the brain. The majority of perimenopausal females experiences cognitive difficulties and have subjective cognitive complaints (SCCs). Verbal episodic memory and processing speed are most negatively impacted by the MT. Cognitive and brain changes during the MT can significantly impact career and financial wellbeing. The MT is thus a critical window to intervene for female brain health. Exercise can reduce dementia risk factors and promote cognitive health. No published randomized controlled trials have examined the effect of exercise on cognitive outcomes in perimenopausal females. 4. OBJECTIVE: To determine if 26 weeks of 2x/week progressive resistance training (PRT) can improve verbal episodic memory performance on the Rey Auditory Verbal Learning Test (RAVLT) compared with balance, flexibility, and tone exercises (BAT) for physically inactive perimenopausal females aged 40-55. 5. RESEARCH DESIGN: A 26-week, assessor-blinded, two-arm, proof-of-concept trial with 50 physically inactive perimenopausal females, aged 40 to 55 years, with subjective cognitive complaints. Participants will be randomized 1:1 to PRT or BAT and measured at baseline, 13 weeks, and 26 weeks.
