目前，光脚跑步很流行，人们说这种跑步方式可以有效缓解背部疼痛。

　　But experts have warned that the growing number of runners using 'barefoot' five-finger running shoes could very easily end up injured.

　　但是，专家声称这种方式对人体有害。有关研究中发现，光脚跑步的方式会增加脚部骨头受损的风险，甚至导致应力性骨折。而女性则是受伤的高危人群。

　　Researchers at Brigham Young University in the U.S found that runners who make the switch from normal trainers to barefoot shoes too quickly suffered an increased risk of injury to bones in the foot, including possible stress fractures.

　　支持光脚跑步的人提出自己的看法，他们认为运动鞋会限制脚部的自然运动模式，引发人体某些部位的疼痛感。因此部分热爱跑步运动的人士选择不穿运动鞋或减少脚部保护装置的方式来进行运动。

　　At the end of the 10-week period, MRIs were again conducted. The MRIs revealed that those who had done more running in the minimalist shoes suffered a greater number of injuries and inflammation.

　　光脚跑步时，脚部受到的冲击力量过大，时间太快，骨头在承接下次冲击时并未做好充分的准备。专家建议，想要换一种运动鞋型跑步的话，必须进行为期至少10周的鞋型适应期，跑步路线长度应当比以前的要短一些。

　　Foot specialists said many injuries resulted from switching from trainers to barefoot too quickly.

　　很多因为光脚跑步受伤的人也是因为调整期太短了，脱了鞋就马上进行和以前一样强度的训练。
