Design: Four-month controlled, randomized, and double-blind study. The patients will be recruited by trained psychiatrists from the Center for Alzheimer's disease in the Institute of Psychiatry of the Federal University of Rio de Janeiro (IPUB/UFRJ). They will be randomized with a blind design to an exercise group (EG) and control group (CG) by a researcher who will not participate of the initial assessments. Intervention On completion of the baseline assessment, all patients will be invited to engage in the exercise program. Those who accept to take part and will be available, having easy access to the facilities, will be included in the sample. The other ones will be included in the control group. So, subjects will be divided by two groups: medical care (control) and medical care + physical exercise. Medical care control group (C): Subjects will maintain clinical treatment. Medical care + exercise group (E): This group will be prescribed the exercise treatment as an adjunctive intervention to drug therapy. Patients who accept to participate in this group will be evaluated with a thorough clinical exam and with a resting electrocardiogram. The training exercise intensity is established at 60% of VO2máx. This intensity was determined using exercise prescription guidelines established by the American College of Sports Medicine (ACSM). Each aerobic session began with a 10-minute warm-up period (40%VO2máx), followed by 20 minutes of continuous treadmill walking at an intensity established by 60% of VO2máx, according to ACMS guidelines (2006). The exercise session will be concluded with a five minutes of cool down. Heart hate (Polar® Sport Tester, Finland) and perceived exertion (Borg Scale) will be monitored and recorded at each five minutes during each exercise session by physical education instructors. Subjects will be encouraged to attend two supervised exercise sessions per week for 16 weeks.
