背景:现有关于长跑运动员在公路赛中脚着地模式的研究表明,绝大多数穿鞋运动员采用后脚跟先着地方式。但尚无研究量化分析赤脚和穿极简鞋运动员的脚着地模式。本研究对休闲路跑中赤脚与穿极简鞋跑者的脚着地模式进行分类研究。方法:采集2011年纽约城市跑步比赛中169名赤脚和42名穿极简鞋长跑运动员脚着地模式的高速录像片段,对个人脚着地模式进行分类,比较赤脚和穿极简鞋运动员前脚掌、中足部、后脚跟着地的频率。结果:赤脚跑步者中前脚掌、中足部和后脚跟着地的比例分别为59.2%、20.1%和20.7%,穿极简鞋跑步者前脚掌、中足部和后脚跟着地的比例分别是33.3%、19.1%和47.6%。两类跑步者中不同着地模式分布差异显著,也明显不同于先前研究中穿普通跑鞋跑步者的脚着地模式分布。结论:赤脚和穿极简鞋跑步者的脚着地模式存在差异,赤脚跑步者中前脚掌着地模式更普遍,后脚跟着地模式较少见。
Background: The current research on long-distance runners’ foot-in-the-road mode shows that most shoe-shoe athletes use the heel-first approach. However, there is no study to quantify the footwork patterns of barefooted and minimalist shoe athletes. In this study, we classify the foot ground pattern of barefoot and minimalist shoe runners in leisure road running. METHODS: A series of high-speed video clips of 169 barefooted and 42 minimalist shoe runners in the 2011 New York City Running Competition were collected. Individual footed patterns were collected and the barefooted and minimalist shoe athlete’s forepaws were compared. Foot, heel after the heel of the frequency. Results: The proportions of forefoot, midfoot and hind heel of barefoot runners were 59.2%, 20.1% and 20.7% respectively. The proportions of midfoot and rear heel were 33.3 %, 19.1% and 47.6% respectively. The differences of distribution patterns of different land types in two types of runners were significant and also significantly different from those in the previous study wearing foot runners. CONCLUSIONS: There is a difference in the mode of footwork between barefooted and minimalist runners, the more common mode of footing in the barefoot runners, and the less posterior heel pattern.
