illustrates the timeline of study assessments and interventions. Using a 2 × 2 design, participants will be randomized to receive aerobic exercise, the DASH diet, a combined exercise and DASH diet intervention, or a health education control group for six months. Assessments of cognitive function and CVD risk factors will be conducted at baseline, following six months of intervention, and again one year following completion of the intervention.
