科学60秒:健壮的18岁vs更高的学术成就

 [听力全文]


Any school kid can tell you: nerds are not usually the most athletic specimens. But a new study suggests that young men who are physically fit tend to be more intelligent. The results appear in the Proceedings of the National Academy of Sciences. 


Animal studies have long shown a link between physical activity and better memory. And in humans, aerobic exercise has been found to boost cognitive function in the elderly. But studies in young adults have yielded conflicting results. Strenuous physical activity in adolescents actually seemed to make mind matters worse. 


To try to settle the issue, scientists in Sweden reviewed the records of more than a million men who enlisted for military service at the age of 18. And they found that cardiovascular fitness, but not muscle strength, was associated with overall intelligence (at least as measured by the Swedish army). And when they consulted additional national databases, they found that physical fitness at the age of 18 also foreshadowed greater academic achievement later in life. Even among the twin pairs, the fitter brother tended to be the smarter. 


So remember, a nerd may not be athletic.  But a lot of athletes may be harboring an inner nerd.


—Karen Hopkin

所有中小学的孩子可能都会认为:书呆子一般不怎么擅长运动。但一项研究表明,对年轻男性而言,身体健康往往意味着他比别人更聪明。该研究结果发表在《美国科学院院刊》(Proceedings of the National Academy of Sciences)上。

 

长期以来的动物研究表明,体育锻炼与更好的记忆力相关;对于人类的研究显示,有氧运动可以提高老年人的认知功能。但在年轻人身上却得出了与之相矛盾的结果:剧烈运动似乎会使青少年的心智状况变得更糟。

 

为了弄清楚这究竟是怎么回事,瑞典的科学家回顾了一百多万名18岁应征入伍男性的记录,发现与整体智力相关的不是肌肉质量,而是心血管健康(至少瑞典军队的测量结果如此)。在查阅更多的国家数据库时,他们发现人在18岁时更好的身体素质也预示着日后更大的学术成就。即使在双胞胎中,更健康的那一个也往往更聪明。

 

所以记住,书呆子可能不擅长运动,但很多运动健将可能会是一个潜在的“书呆子”哦。
