Labor Day’s over, and Americans fortunate enough to have jobs are getting back to work. But all work and no play might make us, well, less productive. That’s the finding of a study that looked at the effects of an employee exercise program in which workers worked out during office hours.

　　Researchers evaluated employees at a large Swiss public dental health organization. Of the 177 participants, one group exercised two and a half hours during the work week; a second group had the same amount of hours off but didn’t exercise; and a control group worked straight through the week.

　　The participants were asked to measure their own productivity and sickness absenteeism after six months and then after 12 months. Those who exercised regularly said they felt more productive and were able to accomplish more during their time working. Perhaps more significantly, they said they lost less time to sick days than those in the other two groups. The study was published in the Journal of Occupational and Environmental Medicine.

　　The researchers say the results suggest that, to increase productivity, employers take time out from work—if they spend it working out.

　　比起那些在上班時(shí)間消磨時(shí)間或者正經(jīng)工作的人，在同時(shí)間段進(jìn)行鍛煉的人顯示出了更強(qiáng)的創(chuàng)造力——辛西婭·格雷伯說。

　　研究人員評(píng)估了一個(gè)瑞士的大型公共牙科保健機(jī)構(gòu)的177名雇員，他們將人們分成幾組：其中一組每周鍛煉兩個(gè)半小時(shí);第二組的休息時(shí)間與第一組大體相當(dāng)，但沒有參加鍛煉;第三組，作為對(duì)照組，整周工作不休息。在半年和一整年以后，工作人員要求受試者評(píng)估自己的創(chuàng)造力和因病缺勤次數(shù)。參加鍛煉的那組人表示，自己的創(chuàng)造力更強(qiáng)了，并且能在工作時(shí)段內(nèi)完成更繁重的任務(wù)。更能證明該項(xiàng)研究結(jié)論的是，比起另兩組的人來，第一組人覺得自己花在生病上的時(shí)間更少了。
