Exercise Really Does Make You Clever
You want to boost your child’s results at school, you could do a lot worse than ensuring that they do plenty of exercise. Scientists have already shown that physical activity can make you brainier. But a team in America has used scans to show that an important part of the brain actually grows in children who are fit. These youngsters tend to be more intelligent and have better memories than those who are inactive.
Scientists also found that one of the most important parts of their brains was 12 percent larger than those of unfit youngsters. They believe that encouraging children to take exercise from a very young age could help them do better at school later. Researchers from the University of Illinois, in the U.S., studied the brains of 49 children aged nine and ten using a magnetic resonance imaging scan, a technique which provides very detailed pictures of organs and tissues in the body.
实验证明，聪明孩子的大脑中重要部分的体积要比身材过胖、或者不健康的孩子大12%。研究者相信，从小就鼓励孩子们运动可以帮助他们在学校生活中发展得更好。美国一所大学运用“磁共振“来进行实验，实验对象为49 名9—10 岁的儿童，这种技术可以精确的显示出人体器官以及各个组织的具体情况。
They also tested the fitness levels of the children by making them run on a treadmill. The scientists found that the hippocampus, a part of the brain responsible for memory and learning, was around 12 percent larger in the fitter youngsters.
Professor who led the study said the findings had important implications for encouraging individuals to take part in sport from a young age. “We knew that experience and environmental factors and socioeconomic status all impact brain development,“ he said. “If you get some lousy genes from your parents, you can’t really fix that, and it’s not easy to do something about your economic status. But here’s something that we can do something about.“
