边走路边发短信为什么更容易摔跤

研究发现，不管人们是否会有意识地加以控制，发短信都会显著扭曲人们的姿势和步态。最值得注意的是，这些志愿者走起路来时，身体的姿势变得更为挺直、僵硬。他们的头歪了起来，而且角度没怎么变化，眼睛盯着屏幕，下巴垂到胸前。他们的脖子和后腰关节活动范围显著变小。据研究人员说，这些参试人员的上半身和腰腹部出现了“更紧张的力学约束”，上臂不再松弛摆动，而是弯了起来，固定在身体两侧。骨盆关节同样僵硬，这令双腿动作变得不再稳定。这项研究的领导者、昆士兰大学荣誉资深研究员西沃恩·斯格布兰(Siobhan Schabrun)介绍说，总的来看，发短信的人走起路来“像是机器人”。

Simultaneously, their gait patterns changed. Texters took significantly shorter steps, and their pace slowed. They also "deviated more from a straight line," the study's authors wrote, meaning that with almost every step, they set their feet farther to the side.

与此同时，他们的步态模式也改变了。发短信的人走的步伐明显变小，速度放慢。研究的作者在论文中指出，他们同时“常常偏离直线”，这指的是参试人员每走一步，步子都会往路边凑近一点。

These adjustments, although relatively slight, could result in both immediate and longer-term physical consequences, Dr. Schabrun said. In the short term, they increase the likelihood that you will trip, and not merely because you neglect to look where you are going while texting. "Previous studies, many in elderly populations, have shown that a more rigid posture, such as this, can put you at greater risk of falling," Dr. Schabrun said.
