Independent Walking for Brain Health


Brief description of study

Physical activity interventions with older adults can improve brain health; however most interventions have been performed in gym-like settings that reach a small sector of the senior population. Since not everyone can access a gym, it is important to study whether brisk walking in real world environments can also help brain health. This study will use mobile health devices to help older adults independently walk for brain health, thus representing a critical step towards the dissemination of physical activity intervention programs aimed at preserving cognitive function in aging.

Detailed Study Description

Physical activity interventions conducted in supervised settings (laboratories and group settings) with older adults have consistently shown improved cardiovascular and cerebrovascular health and improved cognitive function. What is lacking is the development of interventions that take place in real world environments and that take advantage of new technologies to help objectively track real time physical activity behaviors. Real world physical activity interventions have the potential to reach a larger segment of the population and to enhance maintenance after the intervention period ends. This study will develop a novel physical activity intervention using mobile health technologies to promote physical activity levels likely to affect cerebral blood flow and cognition in real world environments in cognitively normal older adults. A randomized controlled trial will be conducted with 30 participants being assigned to the mobile health physical activity condition (walking in free-living environments tracked via mobile health technologies) and another 30 to an education control condition (at home reading about healthy aging materials) for 3 months.
