Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
One hundred forty sedentary older adults will be recruited for this study. Participants will be randomized to an aerobic exercise intervention group, or to a stretching and toning control group. Aerobic exercise sessions will be conducted three times a week for one year, beginning at a light to moderate intensity level over the first two months and progressing to a moderate to high level for the remainder of the year. The control group will meet on the same basis as the intervention group, and will participate in an organized program of stretching, limbering, and toning for the whole body that is specially designed for individuals 60 years of age and older.
During this time, participants will exercise, keep a daily exercise log detailing distance walked (routes will be measured and mapped for participants), time spent in aerobic activity, degree of intensity (rating of perceived exertion), general level of affect during exercise, resting and exercise heart rates. Participants will participate in the MRI/fMRI, physiological (cardiorespiratory) and psychosocial testing prior to the beginning of the fitness training intervention, following 6 months of fitness training, and at the conclusion of the 1 year of fitness training.
