Targeting Cognitive Control to Improve Physical Activity Adherence in Midlife for Alzheimer's Risk Reduction
University of Iowa
Summary
This trial is designed to develop and test the efficacy of cognitive training strategies to improve self-regulatory capacities for middle-aged adults to adopt and sustain a physically active lifestyle. The main questions it aims to answer are: * Can cognitive training designed to improve cognitive control improve physical activity adherence? * What are the psychological, physiological, cognitive, and sociodemographic factors that affect the impact of cognitive control on physical activity adherence? Participants will * Complete a 6-week home-based, computerized cognitive training program * Complete a 6-week home-based, aerobic exercise training program with supervision of a health coach and trainer * Complete a 6-week home-based, aerobic exercise training program prescribed by a health coach and trainer * Visit the laboratory before and after cognitive training, and before and after physical training, to complete assessments of cognition and aerobic fitness
Description
Participants will first be screened to ensure eligibility for participating in moderate to vigorous intensity exercise based on health history and approval from their primary physician or equivalent. Participants will then complete pre-testing and a three-phased intervention. Pre-intervention sessions include study screening, cognitive testing, physical activity assessment, and sub-maximal cardiorespiratory fitness testing. Participants will then be randomized into one of three cognitive training programs for a 6-week cognitive training intervention. The cognitive training program includes 1…
