摘　　要：采用RSscan足底压力鞋垫测试系统,对山东省优秀女子竞走运动员技术周期足底压力进行采集,通过统计学方法对其进行分析,探讨竞走技术周期的足底压力分布特征。研究结果表明,山东省女子竞走运动员着地阶段足跟外侧压强峰值最大,压力中心由外侧过渡到前脚掌,离地阶段前脚掌压强峰值最大,90%的受试者腾空时间都在模糊腾空时间以下,符合国际竞走技术要求。但大脚趾扒地力量太小,不利于后摆腿充分蹬地。It collected the data of pedar during race walking for elite female race walkers in Shangdong by RSscan insole test system and analyzed the characteristics of the distribution of pedar of race walking by statistics to discuss the technology phase of race walking. It investigated that peak pressure of lateral heel is the biggest at first contact, the transition of center of force is on the lateral way,the peak pressure of forefoot is the biggest at last contact,90% of the swing time is out the range of foul fitting the rule of intemational race walking technology. But it is not good for last contact as the less power of big toe.
