好身材等于好大脑 锻炼让你更聪明 If 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 per cent 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。 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 per cent larger in the fitter youngsters。 Professor Art Kramer, who led the study published in the journal Brain Research, 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。 如果您想让您家的孩子在学校的表现更加优异一些，那么就让他们锻炼身体吧，研究表明，身材苗条、匀称的孩子的脑子”更聪明“。这个可不是纸上谈兵，医学扫描已经显示出身材匀称孩子的一部分大脑发育比过胖的儿童要快，而这部分身材匀称的孩子恰恰是在学校成绩好、各方面表现优异的学生。
