We know that exercise has great physical benefits as we age, but there is still much to learn about how it helps our memory and thinking. 

Volunteers for the Combined Exercise Trial or "COMET" study will help us understand how activity like walking and weight lifting combine to help our bodies and our brains. Participants are supported through a year with one of four different types of exercise training. 

This page serves as a central administrative and reporting access point for the study staff and administrative bodies.
