Aerobic Exercise and Cognitive Training in Older Adults

The purpose of this study is to examine the impact of a combined cognitive training and aerobic exercise intervention in sedentary older adults. It is hypothesized that the aerobic exercise will potentiate and increase the generalizability of the cognitive training. Importantly, this study will focus on older adults at-risk for mobility disability. This area is of particular importance considering a large percentage of adults are entering old age and therefore likely to suffer from age-related cognitive decline and mobility disability. To address the investigators' research question 60 adults (age 18-89) will be randomized to one of two 12 week intervention groups: 1) Cognitive Training alone (CT) or 2) Aerobic Exercise + Cognitive Training (AE+CT). The aerobic exercise arm of the study will follow the same format shown to improve a broad range of executive functions in older adults in previous research. The cognitive training arm will consists of a popular commercially-available brain fitness program that has demonstrated specific cognitive improvements and high adherence.
