I will illustrate key statistical challenges of analyzing physical activity data by giving snapshots of three recent projects. First, I will talk about analysis of data collected on 700+ subjects wearing an Actiheart device that collects minute-by-minute activity counts and heart rate for one week as a part of the Baltimore Longitudinal Study of Aging. Secondly, I will talk about an experiment examining changes in activity in a monkey model of Parkinson’s disease that can be used to guide studies of activity changes in human Parkinson’s disease, as well as other related disorders associated with dopamine depletion. Finally, I will talk about “Home” and “Away” models for physical activity and inactivity in elderly adults. These models use both second-by-second activity and GPS data to identify activity “hotspots”, outside locations where alleviated physical activity is recorded.
