体育运动还会上是有助于学术上的成功

　　最近有研究指出，大学生在健身房呆上一个下午不仅能帮助身体保持健康，还能有助于提高他们在学术上的成绩。

　　But spending an afternoon at the gym might yield positive results in the library a new study ?nds. When college students exercise more they don’t just get healthier -- they are also more likely to succeed academically.

　　这项由北卡罗兰州立大学进行的研究表明，在通过对20000名学生在2013-14学年中进行的体育运动分析后，研究人员发现这些学生每多锻炼一个小时，他们毕业的几率(或是来年继续学业的几率)就提高了50%。

　　The study conducted by researchers at North Carolina State University looked at 20000 students’ recreational activities during the 2013-14 school year. For every extra hour that students exercised their odds of graduating (or returning the following year) increased by 50 percent.

　　而就算是很短时间的锻炼-每周多锻炼一个小时，就让这些学生的平时成绩就提高了0.06。

　　And even in small amounts exercise can help: for every one-hour increase in weekly physical activities researchers found students’ GPAs increased by 0.06.

　　北卡罗兰州立大学的研究负责人Jason Derousie说：“虽然这只是一个很小的数字，但也足以证明多花一点点时间锻炼身体能对学业有正面影响。”

　　“It’s a somewhat small increase” said Jason DeRousie co-author of the study and NC State’s assistant director of assessment. “But a small increase in activity does have a positive impact.”

　　不仅如此，学生所在的年级也对锻炼与学业成绩的关系有影响-学生越是在低年级，锻炼对他们学业的帮助和提升越明显。当他们到了大三大四，锻炼对他们学业的帮助反而就没有那么大了。

　　Students’ class years also mattered. The relationship between exercise and GPA was stronger for freshmen and sophomores and weaker for juniors and seniors.

　　学生们在大学里的体育运动包括在运动中心进行健身或事其他的校内竞技性体育运动。将近一半学生每周几乎只进行一次体育运动，还有19.1%的学生一周只进行两次左右的体育运动，只有1.4%的学生每周运动五次或五次以上，甚至有1.4%的学生从不参与运动。

　　Recreational activities included time spent on the recreation center group ?tness and intramural sports. Nearly half of students participated in recreational activities less than once a week while 19.1 percent participated between once and twice a week. Only1.4 percent participated ?ve or more times a week while 16.7 percent never participated.

　　“这项研究结果与大学的文化氛围十分相符-学生们十分注意自己的身心健康，许多学生都能了解运动给他们带来的改变。”北卡罗兰州立大学的大学体育部负责人这样说道。她还说：“我们知道运动有缓解焦虑，沮丧和压力的功效，因此运动对于提升学习成绩很有帮助。”

　　The ndingst well with the cultural moment on college campuses: students are particularly focused on mental health and many understand how exercise affects their well-being said Heather Sanderson co-author of the study and NC State’s associate director of university recreation. “We see the bene?ts of exercise on anxiety and depression and stress” she said. “There has to be a connection to academic success.”

　　参与这次研究的人员表明，过去对于运动和学业已有过类似的研究，但它们都忽略了其他的变量，比如高中时期的平时成绩，SAT成绩，甚至是这些学生的地理分布情况，而这次研究控制了其他变量，让结果更有说服力。

　　While past studies have looked at similar trends the researchers say that most don’t control for other factors that contribute to academic success. The new study controls for factors like high school GPA SAT scores and demographic factors.

　　Sanderson 和 DeRousie准备更进一步的研究运动与学业之间的关系，例如成绩的提高与学生进行的运动种类是否存在关联，进行竞技类体育是否能比进行健身对成绩的提高帮助更大。

　　Going forward Sanderson and DeRousie hope to delve deeper into that connection: Does the type of activity matter? Does playing an intramural sports boost grades more than an afternoon at the gym?

　　参与这项研究的研究人员希望学校的管理者能通过他们的研究成果来为学生创造更多的资源-很多学生可能对运动与学业之间的关系有所了解，但他们很可能需要这样有说服力的研究数据来证明自己的观点，从而行动起来。

　　And in the meantime they hope administrators will use their ?ndings to create resources for students. Many students may see a between exercise and academic success but perhaps they’ll be more motivated seeing their instincts backed up by numbers.

　　DeRousie说，“我们需要把这些研究结果整理好后散播出去，让学生们更加确信自己心中的想法，让这些研究变成推动学生行动的原因。”

　　“We can take these ndings and promote these things that students probably knew were good” DeRousie said. “It gives us a systematic way to give students the extra nudge.”
