Are you preparing for a big test? If so, you may want to play some basketball in between hitting the books. 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. Margaret Barnes, a pediatrician (儿科医生), believes in the importance of exercise. She thinks that many learning disabilities that children have in elementary school or high school can be traced back to a lack of movement as babies. “Babies need movement that stimulates their five senses. They need to establish a connection between motion and memory. In this way, as they get older, children will begin to associate physical activity with higher learning,” says Margaret.

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 percent 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 older people should involve some complexity (复杂). Learning some new skills or motions, such as with yoga or tai chi, 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.

As a child, I never considered myself an athlete at all as I was very uncoordinated (不协调的). However, I did love to run because I felt as if I were flying. But this all changed two years ago when I suffered a knee injury. I was bedridden (卧床不起的) for two weeks and I had a difficult time moving even short distances. I literally cried myself on my way to the car for a few days.

When therapy wasn’t working well for me, I signed up for a hot yoga class for girls, Bikram Yoga, to be exact. Starting a yoga practice was truly a godsend (天赐之物) because it helped me gain strength in my knees but, most importantly, yoga helped me attain a more peaceful state of mind, body and spirit.

Since each class was heated to 105℉, every time I stepped foot in the yoga studio, I’d feel a surge of negative thoughts come upon me like a big ocean wave. Some of these thoughts were, at the beginning of my practice, so strong that I walked out of the class several times. However, as the months passed by, I noticed that when I wasn’t disturbed by my negative thoughts, I could stay in the hot room for longer.

After 3-4 months of practicing hot yoga, I made some progress. I also woke up with so much more energy than I had before starting my yoga practice and I gradually started losing weight from my body. Yoga literally made me feel as if I’d taken a bottle of energy drink and just gave me the burst that helped my knee heal and made my overall health better.

As I saw some of my classmates do poses that looked appealing to me, I started to think maybe I could do them too. Therefore, yoga helped show me that I had no real limitations physically unless I set those limitations myself through eating junk food and thinking in negative limiting terms.

Also, practicing yoga in front of a mirror helped me have more confidence and practicing with a group of people really helped me to feel a greater sense of connection with humanity (人道). Overall, this yoga practice has helped me to see I’m part of a bigger picture in life!

According to a recent report, about 15% of the people in the UK are members of gyms. But are they more likely to be fit?

A study found that gym members were 14 times more active than people who didn’t belong to any health club. Gym members did six hours more exercise a week, and this activity did make them fitter than non-gym members. They also spent less time sitting down every day than non-gym members. The results were the same for men and women.

The study included 405 people between the ages of 30 and 64, and the main characteristics of those who were gym members were the same as those who were not. “But gym members did more training than non-gym members,” said the lead author, Elizabeth Schroeder of the University of Illinois.

While it might seem clear that gym members exercise more and are healthier than non-gym members, Schroeder says this has not been directly shown before. However, the study is only designed to show a tie between gym membership and more exercise. It may be that active people like to join gyms. In the study, people who exercised as much as gym members were also in good health.

You can get the same benefits wherever you exercise. This study shows a gym membership can make you do more exercise, but other research shows that exercising outside has other help. Outdoor activity can make you feel happy about life—especially if you run through a forest.

Outdoor exercise is also more interesting than going to the gym. The first five minutes of outdoor exercise is especially helpful in making people feel good. But Schroeder says that a gym may also encourage greater exercise because it can be social and fun.

【小题1】What did the new study find out?
A.Gym members had healthier eating habits.
B.There were fewer women gym members than men.
C.Gym members were more active than non-gym members.
D.Gym members did at least eight hours of exercise a week.
【小题2】In the study, researchers studied .
A.30 gym members and 64 non-gym members
B.people from different age group
C.some sports lovers
D.405 people who exercise outdoors
【小题3】What does the word “benefits” in Paragraph 5 probably mean?
A.Help.B.Need.C.Advice.D.Injury.
【小题4】Which of the following statements will Elizabeth Schroeder agree with?
A.Women should do more gym exercise.
B.We should be careful with outdoor training.
C.Outdoor exercise is better than gym exercise.
D.It is easier to keep exercising if you go to the gym.
