摘要
Background:Running is becoming an increasingly popular activity among Americans with over 50 million participants.Running shoe research and technology has continued to advance with no decrease in overall running injury rates.A growing group of runners are making the choice to try the minimal or barefoot running styles of the pre-modem running shoe era.There is some evidence of decreased forces and torques on the lower extremities with barefoot running,but no clear data regarding how this corresponds with injuries.The purpose of this survey study was to examine factors related to performance and injury in runners who have tried barefoot running.Methods:The University of Virginia Cenlcr for Endurance Spor! created a 10-question survey regarding barefoot running thai wa.s po.sted on a variety of running blogs and Facebook pages.Percentages were calculated for each question across all surveys.Five hundred and nine participants responded with over 93%of them incorporating some type of barefoot running into their weekly mileage.Results:A majority of the participants(53%) viewed barefoot running as a training tool to improve specific aspects of their running.However,close to half(46%) viewed barefoot training as a viable alternative to shoes for logging their miles.A large portion of runners initially tried barefoot running due to the promise of improved efficiency(60%).an attempt to get past injury(53%) and/or the recent media hype around the practice(52%).A large majority(68%) of runners participating in the study experienced no new injuries after starting barefoot running.In fact,most respondents(69%) actually had their previous injuries go away after starting barefoot running.Runners responded that their previous knee(46%),foot(19%),ankle(17%),hip(14%),and low back(14%) injuries all proceeded to improve after starting barefoot running.Conclusion:Prior studies have found that barefoot running often changes biomechanics compared to shod running with a hypothesized relationship of decreased injuries.This paper reports the result of a survey of 509 runners.The results suggest that a large percentage of this sample of runners experienced benefits or no serious harm from transitioning to barefoot or minimal shoe running.
背景:跑步这项运动越来越受人欢迎,美国有超过5000万人参与。跑鞋的研究和科技日益进步,但并没有降低跑步者的整体受伤率。因此,越来越多的跑步者尝试回归到穿现代跑鞋之前的方式,即穿极简鞋或赤脚跑。有证据显示,赤脚跑可降低下肢力量和力矩,但并无确切数据显示其与损伤之间的相关性。本研究目的是检验影响赤脚跑步者运动表现和损伤相关的因素。方法:利用美国弗吉尼亚大学耐力运动中心创建的一份关于赤脚跑的10项问题调查问卷,并将其发表在各类跑步博客和脸书网上,对所有问卷中的回答进行百分比计算。共有509人填写问卷,超过93%受访者表示在每周的跑步计划中会安排某些形式的赤脚跑。结果:多数受访者(53%)认为赤脚跑是一种训练工具,能改善他们跑步中的某些方面。但也有近一半人(46%)认为赤脚跑训练能替代穿传统跑鞋完成他们的跑步记录。大部分跑步者尝试赤脚跑的原因是想要提高效率(60%)、尝试避免损伤(53%)和/或受最近有关赤脚跑的媒体炒作的影响(52%)。大多数受访者(68%)开始赤脚跑后都没有遭遇新的损伤。事实上有69%受访者在开始赤脚跑后先前的损伤也消失了。受访者称在开始赤脚跑训练后,先前膝盖(46%)、足部(19%)、踝关节(17%)、臀部(14%)和腰部(14%)等部位的损伤均持续好转。结论:先前研究发现,与穿传统跑鞋相比,赤脚跑能引起人体生物力学改变,这被认为能减少损伤。本研究对509名跑步者采取问卷调查,其结果显示参与调查的大多数跑者已从转变为赤脚跑或穿极简鞋跑中获益(或没有增加新的损伤)。
