About this trial
The purpose of this study is to characterize the relationships between changes in cognitive functioning across the day and patterns of physical activity in older adults. Those who participate in the program will complete tests of cognition and several surveys at the start. They will then wear an activity monitor and complete four cognitive tests plus surveys per day for one week. After this week concludes, they will continue completing the surveys and cognitive tests, and will engage in one week of structured exercise at a research center and one week where they work to move throughout the day.
