And if the dance is a good physical exercise as well, the benefits multiply. Young brains may be especially able to boost brain power through exercise, suggested another of Greenough's experiments that showed the most significant changes in the brain occurred among rats that had been exercised when very young. And while animals aren't people, he says it is logical to make the inference that an effect found in rats may also apply to humans.
Human studies have focused primarily on older adults and suggest that regular exercise can improve the speed with which the brain processes information. Measurements made by Arthur Kramer at the University of Illinois demonstrated that inactive adults, aged 63 to 82, could hit buttons faster in response to a tone after they went through a ten-week water exercise course.如果这种舞蹈还是一种良好的体育运动，则益处加倍。格里诺的另一组实验显示，年轻的大脑尤其能够通过运动来增强能力。这组实验表明，从小就锻炼的老鼠，其大脑的变化最为显著。他说尽管动物不是人，但依此推断锻炼对老鼠带来的作用同样适用于人类也合乎逻辑。
对人类的研究主要集中在老年人身上。其结果表明，经常锻炼能提高大脑处理信息的速度。伊利诺伊大学阿瑟•克雷默测量的结果表明，63至82岁不运动的人，在完成为期10周的水上运动课程之后，听音击键的反应加快了。
