Brief Summary

This study is a randomized trial that will compare the effects of two, 12-week activity interventions on patterns of physical activity, physical health, and quality of life measures in 40 older adults who are able to walk for exercise. One intervention will target 150 minutes per week of home-based moderate exercise (e.g. brisk walking), consistent with current recommendations. The other intervention will target a decrease in time spent in sedentary behaviors (e.g. sitting) of 60 minutes per day. Both interventions will wear an activity armband which will allow them to self-monitor their activity or sedentary behavior in real time using a smartphone. The armband will also provide objective data to an interventionist that will facilitate the intervention. The main outcome will be time spent in moderate exercise.

Outcome Measures

Primary Outcomes (1)

• Change in Objectively Monitored Sedentary Behavior

  Subjects will wear a BodyMedia SenseWearPro armband for 7 days during all waking hours at baseline and 12 weeks. This multi-sensor armband will give an estimate of time spent in sedentary behavior over a 1 week period. Sedentary time will be averaged across days and reported as hours per day.

  Change from baseline to 12 weeks

Secondary Outcomes (2)

• Change in Physical Function (Short Physical Performance Battery [SPPB])

  Change from baseline to 12 weeks

• Change in Objectively-monitored Moderate-to-vigorous Physical Activity

  Change from baseline to 12 weeks

Study Arms (2)

Moderate-to-vigorous activity group

ACTIVE COMPARATOR

This group will target achieving the current recommendations for physical activity in older adults. This is 150 minutes of moderate-to-vigorous activity per week.

Other: Moderate-to-vigorous activity group

Reducing sedentary behavior group

EXPERIMENTAL

This group will target a 60 minute per day reduction in sedentary behavior using an objective activity monitor.

Other: Reducing sedentary behavior group

Interventions

Reducing sedentary behavior group OTHER

This intervention will use individual counseling and the the BodyMedia armband to self-monitor sedentary behavior. The goal will be to decrease time spent in sedentary behavior by 60 minutes each day.

Reducing sedentary behavior group

Moderate-to-vigorous activity group OTHER

This group will be administered an individual, behavioral intervention using the BodyMedia armband to self-monitor physical activity. The prescription will be 150 minutes of moderate exercise (e.g. brisk walking) each week.

Moderate-to-vigorous activity group
