Study Overview
Brief Summary
To test the feasibility of an intervention designed to replace sedentary time with physical activity in older Latinos, delivered in their homes to improve cognitive function and brain connectivity.
Detailed Description
After being informed of the study and potential risks, all patients giving informed consent will undergo a focused phone interviews, followed by screening to determine eligibility. Participants that meet inclusion criteria will undergo baseline cognitive function testing via video (following NIH toolbox guidelines for remote cognitive function assessment), followed by a one week measurement of sedentary time using a physical activity monitor (actigraphy). At week 0, participants will be randomized into either a physical activity group to break up sedentary time or activity guidelines only in a 1:1 ratio. Follow up occurs at 6 weeks using the same measures as baseline.

Ecological Momentary Intervention
Participants will receive real time physical activity notifications via a wearable activity tracker and smartphone application.
Intervention: Ecological Momentary Intervention (Behavioral)
Physical Activity Guidelines
Participants will be sent general guidelines for disruption of sedentary time.
Outcomes
Primary Outcomes
Time in Sedentary Bouts
Time Frame: Baseline, 6 weeks
Change from baseline to 6 weeks in minutes spent in sedentary bouts
Number of Sedentary Bouts
Time Frame: Baseline, 6 weeks
Change in number of bouts of sedentary activity at 6 weeks from baseline. One sedentary bout is defined as a 10 minute bout or longer where the activity count is less than 99 counts per minute. Sedentary Bout Parameters Minimum Length: 10 Minutes Minimum Count Value: 0 Counts Per Minute Maximum Count Value: 99 Counts Per Minute
Secondary Outcomes

- Difficulty With the FitBit.(6 weeks.)
- Trail Making Test A(Baseline, 6 weeks)
- List Sorting(Baseline, 6 weeks)
- Enjoyment of the Text Messages.(6 weeks.)
