IMST for Dementia Risk Reduction
Recruiting now · Not applicable · Has a placebo group
Conditions studied: Systolic Blood Pressure, Blood Pressure, Depression - Major Depressive Disorder, Anxiety, Sleep Quality, Physical Function, Cognitive Function
In brief
Using a 2-arm, RCT approach, the primary goal of the study is to evaluate the feasibility and preliminary efficacy of Inspiratory Muscle Strength Training (IMST) as a non-pharmacologic intervention to reduce cardiovascular and cognitive risks in older adults. Next, investigators will examine secondary effects of IMST on mood, sleep quality, systemic inflammation, and physical/motor function. Finally, investigators will assess participant adherence and acceptability ratings of using an 8-week home-based IMST protocol in a diverse older adult sample.
