FRIDAY, Aug. 3 (Health Day News) -- Middle school students who are physically fit are likely to score higher on standardized tests measuring reading and math abilities, a new study has found. And, the average scores went up in connection with levels of fitness, the findings showed.
“The more physically fit kids were, the higher their scores,” said the study’s lead author, Trent Petrie, director of the Center for Sport Psychology at the University of North Texas in Denton. “Parents should encourage their kids to be physically active. There are some real cognitive (认知的) and academic benefits that come from physical fitness”, Petrie said.
Results of the study are scheduled to be presented Friday at the annual meeting of the American Psychological Association in Orlando, Fla. The study included more than 1,200 middle school students from five schools in a suburban area of Texas, with 561 boys and 650 girls. About 57 percent of the children were white, and nearly one-quarter were Mexican American. Nine percent were black and about 2 percent were of Asian descent.
The school district provided the researchers with information on the children’s race, age, grade level and whether they qualified for the free school lunch program, which was an indicator of the family’s socioeconomic status. The schools also provided scores to the tests, which were given between one and four months after the researchers had assessed the children’s levels of fitness. Fitness tests were administered during physical education classes to determine the youngsters’ heart and lung health (cardiorespiratory fitness), as well as their body mass index (BMI), an indicator of how much body fat a person has. The children also filled out questionnaires that helped the researchers determine factors such as self-esteem and social support.
After accounting for factors such as age, sex, family income and self-esteem, the researchers found that for both boys and girls, higher levels of heart and lung health predicted better scores on both the math and reading tests.
For boys, perceived (感观的) social support also seemed to increase their reading scores, the investigators found. In girls, while being physically fit predicted higher reading scores, so too did a higher BMI-- which indicates more body fat. “We were a little surprised by this finding,” Petrie said.
“It was not as strong an association as the one with physical fitness,” he added. The authors suspect it may have something to do with girls this age entering adolescence, which may be related to a higher BMI and slightly higher brain development. He said he plans to make great effort to look for this relationship again in larger studies to see if it was a chance finding, or if the association holds up.
“While we can’t say 100 percent that physical fitness causes better academic performance, we can say that there is a strong and predictive relationship between physical fitness and academic performance,” Petrie said.
“It’s hard to tease apart (梳理) the exact reason for this association,” said Becky Hashim, an attending clinical psychologist and assistant professor in the departments of psychiatry and pediatrics at the Children’s Hospital of Montefiore, in New York City.
“It may be that the children are getting more oxygen. When the heart and lungs are working at a higher capacity, it may allow the brain to work at peak performance. Children who are less fit may be sleepier during school,” she noted. “I personally feel that there’s probably a strong relationship between the confidence you get from being able to do something physical well and academic performance.”
Whatever the reason behind this association may be, “there’s certainly no harm in pushing physical fitness,” Hashim added. “Physical fitness may make you feel better, give you more confidence and improve your performance across the board,” she said.
Petrie agreed. “Physically fit kids are happier, have higher self-esteem and, tend to have better relationships, and now we’re beginning to see that there also seem to be benefits cognitively and academically. Our study sends a strong warning to policymakers to reconsider the service program of physical education classes for kids,” he said.

To get an extra 14 years of life, don't smoke, eat lots of fruits and vegetables, exercise regularly and drink alcohol in a proper amount．That is according to a study published this Monday in the Public Library of Science Medicine Journal．
After tracking more than 20,000 people aged 45 to 79 years in the United Kingdom from about 1993 to 2007, Kay-Tee Khaw of the University of Cambridge and his colleagues found that people who adopted these four healthy habits lived all average of 14 years longer than those who didn't．
“We've known for a long time that these behaviors are good things to do, but we've not seen this benefit before, ”said Susan Jebb, head of Nutrition and Health at Britain's Medical Research Council．“The benefit was also seen regardless of whether or not people were fat and what social class they came from．”
Study participants（参与者）scored a point each for not smoking, regular physical activity, eating five servings of fruits and vegetables a day and moderate alcohol intake．
Public health experts said they hoped the study would inspire governments to introduce policies helping people to adopt these changes．But because the study only observed people rather than testing specific changes, it would be impossible to conclude that people who suddenly adopted these healthy behaviors would surely gain 14 years．
“We can't say that any person could gain 14 years by doing these things, ”said Dr．Tim Armstrong, a physical activity expert at the World Health Organization．“The 14 years is an average across the population of what's theoretically（理论上地）possible．”
“Most people know that things like a good diet matter and that smoking isn't good for them, ”Susan Jebb said．“We need to work on providing people with much more practical support to help them change．”
1.Which of the following DOESN'T belong to the four healthy habits?
A．Eat five servings of fruits and vegetables a day．
B．Do proper exercise in the morning every day．
C．Drinking alcohol in the proper amount every day．
D．Having a cigarette before going to bed every day．
2.We can learn from the passage that ．
A．Susan Jebb did not take part in the study．
B．the study observed people as well as tested specific changes．
C．there's no need for people under 45 to adopt these good habits．
D．only those from first class can benefit from these healthy behaviors．
3.What can be inferred from the passage?
A．All the people are well aware of the harm of their bad habits．
B．People aged 45 to 70 have bad habits in the United Kingdom．
C．Governments should take measures to help people change their bad habits．
D．People have adopted the four healthy habits after knowing they're good．
4.What would be the best title for this passage?
A．Smoking and Drinking Cuts You 14 Years
B．How to Live a Much Healthier Life
C．Healthy Habits May Give Extra 14 Years
D．How to Make Your Life Longer Than Others
