阿利森·奥布里:大学生通常睡得很晚,睡眠时间不规律。大学里的运动员似乎也不例外。斯坦福大学睡眠研究员谢利·马对该大学的一群橄榄球运动员进行了研究,她发现即使橄榄球运动员们觉得他们的睡眠已经很充足,在赛季初还是会出现意想不到的日间疲劳感。她很想知道:如果每个运动员每晚增加两三个小时睡眠,这会对他们的表现产生怎样的影响? Allison Aubrey: College students usually sleep very late and sleep irregularly. Athletes in college seem to be no exception. Stanford University sleep researcher Shelley Horse conducted a study of a group of rugby players at the university. She found that even if rugby players feel that their sleep is adequate, there will be unexpected daytime fatigue at the beginning of the season. She would like to know: If each athlete adds two or three hours of sleep every night, how does this affect their performance?
