Just as exercise strengthens the heart and lungs, bones and muscles, it may also power up the brain. A succession of scientific studies of animals implies that physical activity has a positive effect on mental functioning. "It's clear that the brain benefits from exercise," says brain scientist William Greenough of the University of Illinois at Urbana-Champaign. His studies with rats have demonstrated two primary effects of activity: Vigorous physical exercise provides the brain with more fuel, and skill-based exercise increases the formation of connections in the brain, which, according to the proposals of some scientists, may make the brain better able to process information.
正如运动能强心、健肺、固骨、强肌一样，运动也能健脑。对动物的一系列科学研究表明，体育活动对智力的发挥有积极作用。 伊利诺伊大学厄巴纳──尚佩恩分校的大脑科学家威廉•格里诺说，“很明显，运动使大脑受益。”他对老鼠的研究已经表明运动具有两大功效：高强度体育运动给大脑提供更多的燃料，而技巧性运动则增强大脑神经的联结。依照某些科学家的见解，这种联结能使大脑更好地处理信息。
