Exercise Strategies to Counteract Brain Aging Effects.

Stimulating structural and functional adaptation that improves cognitive performance in specific tasks is the major objective of therapeutic exercise training. In this review we briefly summarize central physiological mechanisms activated by exercise. We further discuss the influence of different kinds of exercise on cognitive improvement. In particular, the effects on cognitive function of aerobic endurance, resistance and respiratory exercise, and combinations thereof are presented. The accumulating evidence reinforces the position that regular aerobic, and possibly also resistance training, offers a powerful tool to cope with biologic aging of central nervous system functions. Nevertheless, the potential magnitude of cognition improvement or restrain of age-related cognition deterioration and the quantity of physical activity required to induce meaningful responses remain to be clarified.
