摘　　要：将三种不同硬度的材料用于职业女鞋中底前掌的制作。使用Footscan R压力板&测力台组合系统采集36名女性穿着三双试验鞋正常行走时的时相和压力中心轨迹数据。三双试验鞋的中底前掌材料分别为SRVS、SRS和SRF;肖氏硬度分别为12、18和22。结果表明:中底材料硬度对步态周期时相和足底压力中心轨迹均有显著性影响。SRS试验鞋初始着地期时长显著大于SRVS试验鞋,前掌着地期时长显著大于SRF试验鞋,蹬离期时长显著小于SRVS和SRF实验鞋。中底硬度过小时COP在内外方向的摆动增加,足部稳定性下降;中底材料硬度过大,会引起跖屈不足而增大摔倒的风险。Three kinds of materials with different hardness were used to manufacture the forefoot area of the midsole for test shoes.Footscan R pressure plate and force platform combined measuring system were used to measure gait cycle and center of pressure(COP),36 healthy adult women participated in the experiment.Subjects wore 3 pairs of test shoes(test shoes’forefoot area materials are SRVS,SRS and SRF respectively,which shore hardness are 12,18 and 22,respectively)walking in their nature motion.Results shown that Midsole-hardness had significant influence on gait cycle and COP.Test shoe with moderate hardness material embedded in the forefoot of midsole(SRS)had significant longer ICP than test shoes with hard(SRF)forefoot midsole material and FFCP than test shoes with soft(SRVS)forefoot midsole material;test shoe with moderate forefoot midsole hardness had significant shortest FFPOP in 3 pairs of test shoes.Soft forefoot midsole hardness increased COP’s change in medial-lateral direction,reduce foot stability;hard rigidity midsole material(SRF)reduced plantar flexion,may increase the risk of fall during walking in high heels.
