Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Moderate to Vigorous Physical Activity (MVPA) Average Per Day

    Average minutes per day spent in moderate to vigorous levels of physical activity (MVPA) (defined as =\>1952 accelerometer counts per minute). MVPA minutes were determined based on one-week of accelerometer wear on the hip at baseline and post intervention.

    Pre (baseline) and post (3 months)

Secondary Outcomes (1)

  • Cerebral Blood Flow (Hippocampal and Frontal)

    Pre (baseline) and post (3 months)

Other Outcomes (3)

  • Memory Function

    Pre (baseline) and post (3 months)

  • Executive Function

    Pre (baseline) and post (3 months)

  • Cardiorespiratory Fitness

    Pre (baseline) and post (3 months)

Study Arms (2)

Mobile Health Walking Condition

EXPERIMENTAL

Physically inactive older adults in this condition will perform 3 months of prescribed brisk walking (to increase cardio respiratory fitness) in their real world environments, using mobile health (mHealth) devices during each exercise session to achieve and maintain a minimum of 150 minutes of moderate to vigorous physical activity (MVPA) per week.

Behavioral: Mobile Health Walking Condition

Healthy Aging Education Condition

ACTIVE COMPARATOR

The education control condition will provide participants with printed materials and homework assignments on issues related to successful aging, such as nutrition, social activity, cognitive and social engagement.
