Dose Response Study of Aerobic Exercise in Older Adults

Start: May 2010

End: April 2014

Enrollment: 100

What Is This Study About?

This 26-week study will assess the effects of three doses of moderate-intensity exercise in sedentary older adults who have age-related cognitive changes but no dementia. Aerobic fitness, physical function, and cognition will be assessed at baseline and 26 weeks to examine the dose-response relationships. At 52 weeks, cognition will be reassessed to examine the durability of cognitive changes.
