This study investigates the effectiveness of functional insoles on plantar pressure distribution during race walking so as to reduce the high plantar pressure and force on race walkers,who tend to suffer from overuse injury.A total of 20 male race walkers aged 21 .1 9 ± 2.66 years and with a mean height of 1 78.85 ±1 4.07 cm were recruited as subjects.Each participant completed a race walk with and without functional insoles.Plantar pressure insoles were used to collect plantar pressure data.A two-way analysis of variance with a mixed design was used to determine the difference between the two conditions.Results show that the use of functional insoles reduced the peak pressure and the impulse in the metatarsal heads and heels and thus suggest that functional insoles have reduced the overuse injury risks of these parts. The first ground reaction force peak also decreased.This result suggests that functional insoles have reduced the risks of foot and leg injuries.%通过分析竞走运动中运动员的足底压力特征，研究足底功能鞋垫对减小足底压力和降低竞走运动员过度使用性损伤的效果。研究对象：20名男性竞走运动员；年龄20．19±2．66岁；身高178．85±14．07厘米。每名受试者分别穿功能鞋垫和不穿功能鞋垫来完成测试。使用足底压力鞋垫来收集足底压力的数据。使用双因素方差分析（Two way ANOVA）来确定两个条件之间的差异。结果显示足底功能鞋垫能够减小跖骨头和足跟的压强峰值和冲量，表明功能鞋垫能够降低这些部位过度使用性损伤的风险。穿功能鞋垫时地面反作用力第一峰值下降，表明足底功能鞋垫能够降低足部和腿过度使用性损伤的风险。
