Overview
Brief Summary
The purpose of this randomized, controlled, prospective study is to evaluate the benefits of combining aerobic exercise with cognitive training for optimizing cognitive function. The study will enroll 109 men and women, age 55-75 years who are in stable health and without contraindications to exercise or evidence of dementia or cognitive impairment. Individuals will be randomly assigned to one of four groups for six months: Aerobic Exercise and Health Education, Home Exercise and Cognitive Training, Aerobic Exercise and Cognitive Training, and Home Exercise and Health Education. Participants will undergo measurements of cognitive function, physical performance, and complete questionaires about daily activities, physical activity, and quality of life at baseline (pre-intervention), and at 6 and 12 months after baseline.

Outcomes
Primary Outcomes
Cooking Breakfast task
Time Frame: Change in task performance between baseline and 6 months
Participants engage in a computerized laboratory simulation of a cooking task to assesses cognitive dimensions of planning, prospective memory, monitoring the progress of ongoing activity, anticipating potential problems, task switching, and task coordination.
Memory for Medical Information
Time Frame: Change in memory task performance between baseline and 6 months
This task measures the ability of the individual to learn and recall complex medical information, and the source of the information.
Virtual Week task
Time Frame: Change in task performance between baseline and 6 months
Participants engage a computerized board game that simulates choices about, and recall of, daily and weekly activities.
