A corresponding control group that didn't exercise showed no improvement. This boost in reaction time after exercise training may occur because declines associated with getting old could actually stem from declines in physical condition. Some scientists speculate the reduction in mental function often attributed to getting old may really be a penalty of neglecting to stay physically active, in addition to related factors such as medicines and poor diet. "In older people, an exercise program appears important for brain maintenance," says Daniel M. Landers, professor of exercise science at Arizona State University, who recently published an article reviewing the scientific literature on activity's effect on the brain. Numerous studies show that children who engage in regular physical activity do better in school than their inactive classmates.
對(duì)照組沒有經(jīng)過鍛煉，其反應(yīng)速度沒有提高。 接受運(yùn)動(dòng)訓(xùn)練之后，人的反應(yīng)速度可能會(huì)加快，這是因?yàn)榕c衰老有關(guān)的機(jī)能衰退實(shí)際上源于體質(zhì)下降。一些科學(xué)家推測(cè)，除了藥物作用和飲食不當(dāng)?shù)认嚓P(guān)因素外，常常歸咎于衰老的大腦功能下降實(shí)際上可能是不注意保持體育運(yùn)動(dòng)帶來的一種后果。 亞利桑那州立大學(xué)的運(yùn)動(dòng)學(xué)教授丹尼爾?M. 蘭德斯最近發(fā)表了一篇文章，對(duì)有關(guān)運(yùn)動(dòng)對(duì)大腦影響的科學(xué)文獻(xiàn)進(jìn)行了綜述。他說：“對(duì)老年人來說，鍛煉計(jì)劃對(duì)維持大腦功能顯得非常重要?！? 許多研究表明，經(jīng)常進(jìn)行體育鍛煉的孩子，在學(xué)業(yè)上比不活動(dòng)的同學(xué)優(yōu)秀。
