摘要
背景：有研究表明足的部分解剖区域支撑着人体大部分质量，并调节着人体的平衡，测量这些区域的压强峰值及分布即可获取足、下肢乃至全身的生理、结构及功能等方面的大量信息。目的：观察健康青少年足球运动员自然行走时左右足峰力值、负荷冲量等的动态足底压力分布。方法：采用三维动态足底压力步态分析系统对16-19岁适龄青少年足球运动员进行动态足底压力测试。结果与结论：受试者足底应力一时间曲线呈明显的双峰型，足底10个分析区域峰力均值在足跟外侧最大（P〈0．01），右足习惯者第1趾、第1，2跖骨、足跟内外侧区域．甲均峰力值右足大于左足（P〈0．05），而第5跖骨、足弓2个区域平均峰力值左足大于右足（P〈0．05）。受试者行走时整足接触阶段、离地阶段负荷中心在第1、2跖骨、足跟内外侧区域，足部最大负荷部位在第1、2跖骨、足跟内外侧区域，男女左右足分布规律基本一致。结果证实，健康青少年足球运动员左右足动态与静态足底压力分布规律存在一致性特征。
BACKGROUND： Former studies indicate that some anatomic regions of feet can not only support the most of the human body weight, but also balance the human body. Massive information concerning the physiology, structure and function of foot, lower limb, and even the whole body can be gained by measuring the peak pressure and distribution of these regions. OBJECTIVE： To observe the dynamic plantar pressure distribution of naturally walking healthy adolescent soccer players, such as peak power values of both feet, loading impulse. METHODS： The dynamic plantar pressure of 16 to 19 years old adolescent soccer players were tested using the F-Scan Gait three-dimensional dynamic plantar pressure analysis system. RESULTS AND CONCLUSION= Plantar stress-time curves showed a clear double-peak type. The mean peak force value of the 10 tested plantar region all reached maximum in the lateral heel （P 〈 0.01）. For the ones preferred right foot, the mean peak force value of great toe, the first and second metatarsals, the inner and outer heel regions of the right foot was larger than that of the left foot （P 〈 0.05）. While the mean peak value of the fifth metatarsal, two foot arch regions of the left foot was larger than that of the right foot （P 〈 0.05）. During walking, the load centers in the whole foot contact phase and the outside-ground phase were the first and second metatarsals, the inner and outer heel regions. The maximum load parts of foot were the first and second metatarsals, the inner and outer heel regions. The distribution regularity of left foot was similar to that of the right foot, and there was no difference between genders. In conclusion, there is a consistency in the distribution regularities of the left and right foot static and dynamic plantar pressure analysis in the healthy adolescent soccer players.
