六个月后,志愿者们第二次抽血,完成关于日常活动的问卷。结果表明,锻炼组的人不出所料比从前锻炼得更多。但是他们大部分人坐的时间也比从前少了很多。
And when the scientists compared telomeres, they found that the telomeres in the volunteers who were sitting the least had lengthened. Their cells seemed to be growing physiologically younger.
科学家们在比较端粒时发现,坐得最少的志愿者的端粒延长了。从生理上讲,他们的细胞似乎更年轻了。
Meanwhile, in the control group telomeres generally were shorter than they had been six months before.
与此同时,控制组志愿者的端粒总体来说比六个月前更短了。
But perhaps most interesting, there was little correlation between exercise and telomere length. In fact, the volunteers in the exercise group who had worked out the most during the past six months tended now to have slightly less lengthening and even some shortening, compared to those who had exercised less but stood up more.
但是也许最有趣的是,锻炼与端粒长度之间几乎没有联系。实际上,在锻炼组中,在这六个月里锻炼最多的人与锻炼得不多但是站立时间更长的人相比,端粒增长得略微少一些,有些甚至缩短了。
Reducing sedentary time had lengthened telomeres, the scientists concluded, while exercising had played little role.
