Brief summary: The objective of this pilot study is to quantify patterns of activity and sedentary behavior in independent living residents and to collect preliminary data on the feasibility of reducing sedentary behavior using a 12-week, behavioral intervention in older adults. We will also measure the effects of reducing sedentary behavior on physical function, sleep, quality of life, energy/mood, pain and blood pressure. Participants will act as their own controls through the use of a double baseline period to examine stability of the physical activity and outcome measures.

Detailed description: Aim 1: To measure the amount of sedentary time and ambulation (steps) in older adults residing in independent living communities.

Aim 2: To test the acceptability and effectiveness of a 12-week sedentary behavior intervention to decrease sitting and increase ambulation which will in turn improve physical function (primary outcome) as well as sleep, quality of life, energy/mood, pain and blood pressure (secondary outcomes) in independent living residents.

Background: Sedentary behavior, or sitting for prolonged periods during waking time, is identified as a health risk that is distinct from the failure to achieve sufficient physical activity. Older adults exhibit the greatest time in sedentary behavior which is concerning given its association with chronic disease and poorer physical function. Preliminary data suggest that individuals in long term care facilities may have even greater sedentary time due to personal factors and environment influences. Most often, exercise is targeted as a mechanism for ameliorating frailty in older adults; however, reduction in sedentary time may be a more appealing and realistic goal for improving health outcomes. Despite this, studies targeting sedentary time in older adults, particularly in those in independent living facilities, are lacking.

Eligibility criteria: Inclusion Criteria:

* Age ≥ 60 years
* Reside in an independent living facility
* Ability to walk approximately 100 feet (length of a hallway) with or without an assistive device

Exclusion Criteria:

* Unable to provide informed consent
* Presence of a comorbid medical condition that would limit ability to stand and perform light activity (e.g. recent orthopedic injury/surgery involving the lower extremities, currently undergoing treatment for cancer,acute cardiovascular conditions)
* Presence of a skin condition that would prohibit the use of an activity device attached with medical tape to the thigh (e.g. open wound on the thigh, skin infection on the lower extremity)
