Doctors are starting to find more and more information that suggests a connection between exercise and brain development. Judy Cameron, a scientist at Oregon Health and Science University, studies brain development. According to her research, it seems that exercise can make blood vessels (血管), including those in the brain, stronger and more fully developed. Dr Cameron claims this allows people who exercise to concentrate better. She says, “ While we already know that exercise is good for the heart, exercise can really cause physical changes in the brain.” The effects of exercise on brain development can even be seen in babies. Babies who do activities that require a lot of movement and physical activity show greater brain development than babies who are less physically active. With babies, even a little movement can show big results. Older people can beef up (加强) their brain as well. Scientists from 11 universities studied a group of seniors ranging in age from 70 to 79. Their study showed a short-term memory increase of up to 40 per cent after exercising just three hours a week. The exercise does not have to be very difficult, but it does have to increase the heart rate. Also, just like the motion for babies, exercise for seniors should involve some complexity (复杂). Learning some new skills or motions, such as with yoga or Tai Ji, helps open up memory paths in the brain that may not have used for a long time. For most people, any type of physical activity that increases the heart rate is helpful. The main goal is to increase the brain’s flow of blood. And your brain can benefit from as little as three hours of exercise a week. 1．The passage is mainly about _____.
