好身材等于好大腦 鍛煉讓你更聰明 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。 如果您想讓您家的孩子在學(xué)校的表現(xiàn)更加優(yōu)異一些,那么就讓他們鍛煉身體吧,研究表明,身材苗條、勻稱的孩子的腦子”更聰明“。這個可不是紙上談兵,醫(yī)學(xué)掃描已經(jīng)顯示出身材勻稱孩子的一部分大腦發(fā)育比過胖的兒童要快,而這部分身材勻稱的孩子恰恰是在學(xué)校成績好、各方面表現(xiàn)優(yōu)異的學(xué)生。 實驗證明,聰明孩子的大腦中重要部分的體積要比身材過胖、或者不健康的孩子大12%。研究者相信,趁孩子年幼的時候多多鼓勵他們運動可以幫助他們后天在學(xué)校的生活中發(fā)展更好。美國一所大學(xué)運用”磁共振“來進行實驗,實驗對象為49名9---10歲的兒童,這種技術(shù)可以精確的顯示出人體器官以及各個組織的具體情況。 我們了解到,大腦海馬區(qū)(hippocampus)是幫助人類處理長期學(xué)習(xí)與記憶聲光、味覺等事件的大腦區(qū)域,發(fā)揮所謂的“敘述性記憶(declarative memory)”功能。實驗中,研究人員運用跑步機來測試孩子們的體力以及耐力,用”磁共振“將體力好的孩子的腦部與體力不好的孩子的腦部做了對比。結(jié)果顯示,體力好的孩子中的”大腦海馬區(qū)“部分比體力不好的孩子的部分要大12%。 倡導(dǎo)做實驗的教授說,研究的結(jié)果證實了讓孩子在年幼的時候加強鍛煉身體的重要性。我們知道”經(jīng)驗“”環(huán)境“以及社會因素都會對大腦的發(fā)展產(chǎn)生影響。如果不幸遺傳到了父母不大優(yōu)良的基因,或者經(jīng)濟條件又不是那么優(yōu)越的情況下,我們更應(yīng)該鼓勵孩子多運動,從后天鍛煉自己的身體上來尋求進步。 |
