摘要
主要探究性别与足弓类型对慢跑状态下足底压力中心轨迹的影响.使用Footscan平板式足底压力测试系统(采样频率为300 Hz)采集47名大学生(男性19名、女性28名)裸足状态下以3 m/s速度慢跑时的足底压力中心轨迹数据.采用双因素重复测量方差分析法分别对足底压力中心轨迹的速率、位移等指标进行统计分析,显著性水平α设为0.05.结果发现性别因素在前足蹬伸阶段对压力中心侧向偏移量(COPx)的影响具有显著性(P=0.035),且男性COPx大于女性;足弓类型在支撑期的三个关键时刻对COP x的影响均有显著性(P>0.05);不同足弓类型对垂直支撑时相的影响具有显著性(P=0.034);在前足蹬伸时相三种足弓类型之间的差异具有显著性(P=0.028).这些结果进一步为不同性别与足弓类型人群的矫形鞋(垫)设计提供了理论支持.具体而言,对女性来说,需要在前掌蹬伸阶段增大COP向内侧的位移,以增强人体稳定性;高弓足则需要更多的外侧支撑,而扁平足需要更多的内侧支撑来提高稳定性及减少下肢应力.
To explore the effect of gender and arch type on the trajectory of the center of pressure in jogging.The Footscan plantar pressure measuring plate(sampling frequency 300 Hz)was used to collect the data of foot center of pressure of 47 college students(19 males and 28 females)jogging at 3 m/s in barefoot.The center of pressure variables was statistically analyzed by the two-way ANOVA with repeated measures,and the significance level was set as 0.05.The results showed that the gender factors had a significant effect on the COPx during the forefoot push off phase(P=0.035),and male COPx was greater than female;The arch type had significant effects on the COPx at three phase during standing(P>0.05);the impact of the arch type on the foot flat phase was significant(P=0.034);The impact of the arch type on stance phase was significant during forefoot push off phase(P=0.028).These results further provide theoretical support for the design of orthopedic shoes(insoles)for people of different genders and arch types,specifically,it is necessary to increase the displacement of COP inward during the forefoot extension to enhance the stability of the human body for female;cavus feet were required more lateral support,while flat feet require more medial support to improve stability and reduce lower limb stress.
