Do you think sitting and studying all the time will improve your grades? Think again. Getting some exercise may help,too.

New research with older people suggests that taking regular (規(guī)律的)walks helps them pay attention(注意)better than if they didn’t exercise.

Previous research had shown that mice learn, remember, and pay attention better after a few weeks of working out on a running wheel. Mice that exercise have greater blood(血)flow to the brain than those who don’t. Their brain cells also make more connections(聯(lián)系)•

Neuroscientists (神經(jīng)系統(tǒng)科學(xué)家)from the University of Illinois at Urbana-Champaign wanted to find out if the same thing is true for people. First, they measured the physical fitness of 41 adults, ages 58 to 77,after each person walked 1 mile. Then, those people looked at arrows(箭)on a computer screen and had to use computer keys to show which way one particular arrow was pointing.

Adults who were physically fit were faster at the arrow task, and their answers

were just as right as the less-fit persons, the researchers found. The fitter persons also had more blood flow to a part of their brain. So, even going for a walk every 2 or 3 days for just 10 to 45 minutes can help. That should be good news for your grandparents. The effects of exercising on the brains of younger people haven’t been studied yet. Still, it can’t hurt to take some breaks and go for a walk or run around with your friends. You might even do better in school.
