Exercise and cognitive training hold promise for delaying progression of MCI. Exercise improves cognitive ability, brain function, and brain structure in older adults. Cognitive training has been shown to durably improve mental abilities and functional status in older adults. In addition, persons with MCI respond to some forms of cognitive training just as robustly as healthy older adults.
This pilot study is a 4 group design with a home-based multi-modal physical exercise intervention, cognitive training, combined cognitive and physical training, and a social contact control enrolling older adults with MCI.
This pilot study is designed to be consistent with current recommended approaches to establishing trial feasibility. If the aims are achieved, it will provide a conceptual and practical rationale to support a large, multi-site, randomized clinical trial to test the efficacy of combined physical and cognitive training in delaying time to a clinical diagnosis of dementia.

Experimental: Combined Cognitive and Physical
This consists of 45 minutes of Cognitive arm + 45 minutes of Physical arm (90 minutes total), 3 days a week for 12 weeks (36 sessions).
Behavioral: Combined Cognitive and Physical
Combined modules provide Cognitive training from Posit Science designed to improve information processing speed, learning, memory, and attention, and Physical training focused on seated aerobic and progressive resistance exercises designed to improve aerobic capacity, muscular strength, and endurance consistent with current exercise recommendations for older adults.
Active Comparator: Cognitive
This consists of 45 minutes of cognitive modules from Posit Science, 3 days a week for 12 weeks (36 sessions).
Cognitive modules from Posit Science are designed to improve information processing speed, learning, memory, and attention.
Active Comparator: Physical
This consists of 45 minutes of multi-modal physical exercise, 3 days a week for 12 weeks (36 sessions).
Physical modules are focused on seated aerobic and progressive resistance training designed to improve aerobic capacity, muscular strength, and endurance consistent with current exercise recommendations for older adults.
Sham Comparator: Control
This consists of 45 minutes of group discussion and instruction in health self-management and successful aging, 2 days a week for 12 weeks (24 sessions).
Control modules provide social contact for group discussion and instruction in health self-management and successful aging.
