Brief Summary: This is a randomized, 26-week study of supervised exercise assessing three doses of exercise in sedentary individuals 65 years of age and over with age-related cognitive changes. A total of 100 subjects (n=25 in each of four groups) will be randomized to a non-aerobic control group, 75 minutes, 150 minutes, or 225 minutes a week of moderate intensity aerobic exercise spread over 3 to 5 days a week for 26 weeks. These exercise doses represent 50%, 100%, or 150% of the recommended exercise dose. Participants will be directly supervised during all exercise sessions for the first two months after which direct supervision will occur during at least one session a week. This is intended to provide increased flexibility while also maintaining direct contact with the participant to enhance adherence. 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 durability of cognitive changes.

Arms Assigned Interventions
Active Comparator: Nonexercise control group Behavioral: Nonexercise control group
Participants randomized to the nonexercise control group will be asked to maintain their current level of physical activity during the 26-week active study period. They will perform outcome assessments and receive the same telephone checks as the exercise group at baseline, 26 and 52 weeks. The purpose of including a non-exercise control group is to allow adequate comparisons with the low, medium and high exercise dose groups on changes in cognitive and physiologic outcome measures.
Experimental: Aerobic Exercise Group 1 Behavioral: Aerobic Exercise Group 1
The 50% group will perform 75 minutes a week of moderate intensity exercise spread over 3 days.
Experimental: Aerobic Exercise Group 2 Behavioral: Aerobic Exercise Group 2
The 100% group will perform 150 minutes a week of exercise over 3 - 5 days
Experimental: Aerobic Exercise Group 3 Behavioral: Aerobic Exercise Group 3
The 150% group will perform 225 minutes a week of exercise over 4 - 5 days.
Open or close this module Outcome Measures
Primary Outcome Measures:
1. Primary Cognitive Outcome Measure: General Cognition
[ Time Frame: baseline, 26 , and 52 ]

We predict that general cognition will be enhanced by the aerobic exercise intervention. Greater cognitive gains will be made by individuals with more fitness gains. Finally, the intervention will affect all cognitive domains but it will affect executive functioning domains relatively more than other domains.
Secondary Outcome Measures:
1. Secondary Outcomes will measure memory
[ Time Frame: baseline, 26 , and 52 ]

Tests selected consistently yield moderate to large sized exercise-related effects across many studies and possess good ecological validity when aggregated by cognitive domain.
