Physical Activity and Sleep in Older Adults
Physical activity and sleep can be measured in many ways. Our lab has conducted research with self-reports, caregiver reports, and electronic monitors including ActiGraph and ActivPAL. The ACCEL and PASS studies measured sedentary behavior, physical activity, and sleep in older adults with and without Alzheimer’s Disease and relate it to various health outcomes including cognition and depressive symptoms. We have evaluated variability in daily activity patterns across hours of the day and across days of the week.
