Taking more walks

Sitting and studying all the time will raise your grades. Getting some exercise may help, too. New scientists say that taking walks makes kids pay attention better.

Earlier research report had shown that mice learn, remember, and pay attention better after they exercise on a running wheel for several weeks. Mice which exercise have more blood run to the head than those who don’t. And they can think faster.

Scientists from University of Illinois at Urbana-Champaign wanted to find out if the same thing is true for humans. First, they examined the health of 41 adults, aged 58 to 77, after each person walked 1 mile. Then, they input their information onto the computer and worked out the results. They looked at arrows(箭头) on the computer screen and had to use the computer and arrows to show which direction was special.

Adults who were healthy were faster at the arrow task, and their answers were just as right as those who were less healthy, the scientists found. The healthy persons also had more blood run to a part of their head responsible for paying attention and making decisions.

In a second study, 15 old people who finished a 6-month training class were faster at attention tasks compared with 14 students who did few simple exercises for the same amount of time.

So, even going for a walk every 3 days for just 10 minutes can help. That may be good news for your grandparents as well. The results of exercising on the brains of younger people haven’t been studied yet. Still, it’s useful to take unusual study breaks, go for a walk or run with your friends. You might even do better in school after that.
