This morning I saw a young woman walking her dog with her little son (no school, President’s Day) while I was biking into work along the Leslie Middle School walking/bike path. I stopped and said, “Hi, did you know, there is a really great place to walk just over there?” (pointing to Pringle Creek). She said, “Actually, that’s one of my favorite places to walk!!” She was headed that way.

It reminded me of when Julia McFerron told the Statesman Journal that Pringle Creek was her “Favorite Salem Secret.” 
It also reminded me of another reason why, I think, we are naturally drawn to going for walks — not only because it makes us feel good, it’s healthy, it helps us get centered, but it also improves brain function…

Fitness: A Walk to Remember? Study Says Yes

In healthy adults, the hippocampus — a part of the brain important to the formation of memories — begins to atrophy around 55 or 60. Now psychologists are suggesting that the hippocampus can be modestly expanded, and memory improved, by nothing more than regular walking.
In a study published on Jan. 31 in The Proceedings of the National Academy of Sciences, researchers randomly assigned 120 healthy but sedentary men and women (average age mid-60s) to one of two exercise groups. One group walked around a track three times a week, building up to 40 minutes at a stretch; the other did a variety of less aerobic exercises, including yoga and resistance training with bands.After a year, brain scans showed that among the walkers, the hippocampus had increased in volume by about 2 percent on average; in the others, it had declined by about 1.4 percent. Since such a decline is normal in older adults, “a 2 percent increase is fairly significant,” said the lead author, Kirk Erickson, a psychologist at the University of Pittsburgh. Both groups also improved on a test of spatial memory, but the walkers improved more.
While it is hard to generalize from this study to other populations, the researchers were delighted to learn that the hippocampus might expand with exercise. “And not that much exercise,” Dr. Erickson pointed out.
People don’t even have to join a gym, he noted. They just need shoes. PAULA SPAN
