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.

China may be the world's most populous country ,and it won the most gold medals at the 2008 Summer Olympics in Beijing. But its prowess at soccer is lamentable. China is ranked 84th in the sport's world standing.
Chinese are huge soccer fans, and hundreds of millions are expected to tune in to the World Cup, with all the matches broadcast live on public TV. But this time the Chinese don't have their own team to root for.
"Chinese have a reputation of being good at math, but they have trouble explaining why a population of 1.3 billion cannot produce a winning 11-member soccer team," said Xu Guoqi, a history professor at the University of Hong Kong. Journalists and soccer fans offer a number of reasons, most often money issues, politics, corruption(腐败)and culture, and sometimes a combination of the four.
Even though China now boasts wealthy companies and individuals who could sponsor(赞助) teams, there is little support as long as Chinese teams are perceived as perennial losers. "This is a very bad circle," Ma said. "No results, no money. No money, no results."
Few Chinese children are playing soccer. Some sports journalists and fans attribute the lack of interest partly to schools de-emphasizing sports in general and the lack of playing venues in the country's dense urban areas. "What can Chinese kids do?” said Fan Huiming, 61, a Chinese soccer fan who grew up watching matches at Beijing's Workers' Stadium, which was built in 1958 near his childhood home. "If they play soccer, the ball may fly directly into the glass of someone's home."
For young people, soccer has largely been eclipsed by basketball, thanks in part to Chinese NBA players who are treated like rock stars. Journalists and fans say NBA's aggressive campaign of marketing and merchandise in China has helped swell the popularity of basketball. By comparison, they noted that international soccer does not even have an office in China.
Rowan Simons, a Briton who came to China more than two decades ago and discovered he wasn't able to play weekend soccer, has been on a campaign to popularize the sport here. Simons said the main problem is that soccer elsewhere has traditionally started as a series of neighborhood clubs, but in China, "there's virtually no football at community level".
"Football in China can only succeed if it's a grass-roots activity organized by the people," he said.
