Exercise and the brain

While I would shy away from the word “best,” there is little doubt that regular aerobic exercise has substantial cognitive benefits.

Aerobic exercise helps our brains in several ways. First, and, perhaps, foremost, it reduces the risk of cardiovascular disease and vascular dementia.

Second, as one study reported:

“These results suggest that cardiovascular fitness is associated with the sparing of brain tissue in aging
humans. Furthermore, these results suggest a strong biological basis for the role of aerobic fitness in maintaining and enhancing central nervous system health and cognitive functioning in older adults.”

In addition, aerobic exercise has been associated with improved memory and increased size of the brain region known as the hippocampus. The hippocampus is involved in the consolidation of long term memories.

Finally, exercise has been shown to increase levels of brain-derived neurotrophic factor, which, in turn, stimulates neuron growth. 

So regular aerobic exercise should be a central part of any memory improvement program. In addition, this research suggests that efforts to cut physical education programs in the schools may be short sighted.
