New research from the University of Illinois at Urbana-Champaign shows that walking can actually boost the connectivity within brain circuits, which tends to diminish as people age, and can lead to improvements in memory and attention span.
The study, led by Dr. Arthur F. Kramer, tracked 70 adults from 60 to 80 years old over the course of a year. A toning, stretching, strengthening group served as a control against which to evaluate the previously sedentary walkers.
"Individuals in the walking group, the aerobics training group, got by far the largest benefits," he said.
