边走路边发短信为什么更容易摔跤

So researchers at the University of Queensland in Brisbane, Australia, rounded up 26 healthy adults for a study, published last month in PLOS One, and sent them strolling repeatedly along a 28-foot stretch of hallway while cameras captured their steps. In one setup, the volunteers walked without a phone; in another, they read a long text on a phone's screen; and in a third, they texted "The quick brown fox jumps over the lazy dog." The volunteers were told to hold the phone and type as they usually would. They were also asked to try to walk as normally as possible.

澳大利亚布里斯班的昆士兰大学(University of Queensland)研究人员因此做了一项试验，征集了26名健康成人，并请他们在一条长为28英尺的走廊上反复行走，用摄像机记录下他们的脚步。一次安排这些志愿者在走路时不拿手机；另一次边走边在手机上看一条长长的短信；第三次则是边走边发短信，内容为：敏捷的褐色狐狸跳过了懒狗。志愿者需要手持手机，用习惯的方式来编辑短信内容，同时需要走起路来尽量跟平常一样。这份研究上月发表在《公共科学图书馆·综合》(PLOS One)上。

As it turned out, texting significantly distorted their gait and walking form, whether they intended to contort themselves or not. Most noticeable, the volunteers began to walk with a more upright and rigid body position. Their heads froze into cocked and largely unchanging positions, eyes on the screen, chins bent toward their chests. Their necks and lower back joints had significantly less range of motion. They displayed "tighter mechanical constraint" in their upper bodies and midsections, according to the researchers; arms stopped swinging loosely and were bent and locked into place. The pelvic joints likewise stiffened, making leg motion jerkier. In general, the texters moved "like robots," said Siobhan Schabrun, an honorary senior fellow at the University of Queensland, who led the study.
