體育鍛煉對學習成績有幫助

Recently we told you about a finding that more years of school could help students get higher scores on intelligence tests.That was the finding of a study of teenage males in Norway.Now,other research shows that physical activity may help students do better in their classes.

最近我們講述了關(guān)于上學時間更長能夠幫助學生在智力測驗中得到更高分數(shù)的一項發(fā)現(xiàn)，這是針對挪威青年男子的一項研究?，F(xiàn)在其它研究表明，體育鍛煉可能幫助學生在功課上做得更好。

The research comes as educators in some countries are reducing time for activities like physical education.They are using the time instead for academic subjects like math and reading.

這項研究正值一些國家的教育工作者減少體育課一類活動時間這樣一個時期。他們把這些時間轉(zhuǎn)而用于數(shù)學、閱讀一類的學科。

Researchers at VU University Medical Center in Amsterdam reviewed the results of fourteen studies.Twelve were from the United States,one from Canada and one from South Africa.

阿姆斯特丹自由大學醫(yī)學中心的研究人員重新評估了14項研究的研究結(jié)果。其中12項來自美國，一項來自加拿大，一項來自南非。

The studies appeared between nineteen ninety-seven and two thousand nine.They included more than fifty-five thousand children,ages six to eighteen.

這些研究發(fā)表于1997年至2009年期間，涉及了超過5.5萬名年齡在6到18歲的兒童。

Researcher Amika Singh says the studies showed a link between physical activity and scores on subjects such as math,English and reading.

研究人員阿米卡·辛格(Amika Singh)表示，這些研究表明了體育鍛煉和數(shù)學、英語和閱讀一類學科分數(shù)之間的關(guān)聯(lián)。

AMIKA SINGH:"Based on the results of our study we can conclude that being physically active is beneficial for academic performance."

辛格：“根據(jù)我們的研究結(jié)果，我們可以得出結(jié)論，體育鍛煉對學習成績有幫助。”

Ms.Singh offers some possible explanations.

辛格女士提供了一些可能的解釋。

AMIKA SINGH:"There are,first,physiological explanations,like more blood flow,and so more oxygen to the brain.Being physically active means there are more hormones produced like endorphins.And endorphins make your stress level lower and your mood improved,which means you also perform better."

辛格：“第一種是生理方面的解釋，如血液流動增加，所以向腦部的供氧增加。進行體育鍛煉意味著產(chǎn)生更多激素，例如腦啡肽。腦啡肽使得你壓力水平降低，情緒改善，這也就意味著表現(xiàn)更好。”

Also,students involved in organized sports learn rules and how to follow them.This could improve their classroom behavior and help them keep their mind on their work.

此外，參加有組織運動的學生能夠從中學到規(guī)則以及如何遵守規(guī)則。這能夠提高他們的課堂表現(xiàn)，幫助他們專心學習。
