The current study will provide data to estimate expected effect sizes for power analyses and sample size calculations. It will also provide an opportunity to optimally design a larger trial that can be extended to multiple sites to more definitively examine the role of exercise as a therapy in AD. The current project's aims are an important and necessary developmental step given the lack of fitness data in AD and the limited knowledge of the mechanisms that may form the basis of an association between aerobic fitness and AD."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '55 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Informed consent provided by the participant or the participant's legally acceptable representative\n* Age 55 years or older\n* Diagnosis of Probable AD according to the National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA)\n* Clinical Dementia Rating (CDR) of 0.5 (very mild) or 1 (mild dementia)\n* Mini-Mental Status Exam Score of 16 to 30, inclusive.\n* Rosen Modified Hachinski score of 4 or less\n* Community dwelling with a caregiver able and willing to accompany the participant on all visits, if necessary.
