摘　　要：通过Footscan足底压力步态分析系统测试优秀竞走运动员竞走支撑相足底压力分布。结果表明,竞走支撑足足底压力时间曲线具有双峰特征,足中部发力控制能力较强;压力中心轨迹在横向摆动幅度较小,纵向移动速度均匀,在足中部支撑时移动速度较快;支撑时所受冲量分布全足底,在鞋后跟着地阶段大多出现足跟内翻,在足中部支撑和蹬伸阶段左足偶有内翻现象出现,具有项目特有的动力定型。建议在训练中应增加侧重左足外侧副韧带和足底肌腱韧带的专项力量练习,以提高竞走运动员的足平衡控制能力。The purpose of this study was to examine and analysis the pressure distribution under the foot in Chinese elite race walker during walking through Footscan plantar pressure distribution analytical system. The result shows that the curve of plantar pressure to time of elite athletes in race walking is a two-peak wave shape. The variation of COP in mediolateral （M/L） direction is small. Relative vertical impulses indicate that load is almost evenly spread over the entire plantar surface. These findings mentioned above suggest that we should pay attention to enhance the capacity of plantar flexor to improve foot control.
