Aging, Cognition, Physical Activity
Conditions
Brief summary
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.
Interventions
BEHAVIORALExercise
During this week, participants will be encouraged to complete 5 supervised center-based aerobic exercise sessions at a moderate to vigorous intensity.
BEHAVIORALDaylong Movement
Participants will work to increase daily steps by approximately 25% while avoiding sustained periods of sitting.

Intervention model description
Participants complete one "control" week and then are randomly assigned to begin with either exercise or moving across the day before engaging in the remaining intervention arm.
