Brief summary
This study is intended to clarify the benefits to brain health and thinking processes that result from different forms of exercise. In particular, this study will investigate the possible benefits of physical exercise (such as pedaling an under-table stationary elliptical) or mental exercise (such as playing a videogame on a portable tablet), or combining these activities together (as in the iPACES™ exergame).
Interventions
following 2-week placebo for all participants, participants in this arm will then start their active intervention with a randomly assigned 2-week physical exercise-only intervention, then 2-week cognitive exercise-only intervention, then 2-week and 3 month intervals of iPACES™ (interactive physical and cognitive exercise)
