Both walking and its faster, running, consist of cyclical subsequent phases of swing and support; however, they differ in their time proportions as well as magnitude of acting forces. There is a lack of studies concerning the long-term consequences of repeated jogging cycles on the function of feet and, above all, on their permanent impact on the shape of foot arches.
The objective of this study was to answer the question whether regular jogging changes the shape of the transverse and medial longitudinal arches of the feet.
The research material consisted of 96 women with an average age of 26.57, and included 50 actively jogging women, and 46 of non-joggers. The study was performed with the use of EMED-SF force platform. The plantar surface of the foot was divided into 10 regions according to Cavanagh, for which peak pressure and contact time were established. Two indicators were defined: metatarsal bone pressure distribution pattern acc. to Kantali, and longitudinal arch index acc. to Cavanagh.
The data obtained revealed more frequent occurrence of the greatest pressure under the centrally located metatarsal heads (lack of functional foot transverse arch) among the female joggers, compared with the non-joggers. Moreover, the findings indicate the higher frequency of medial longitudinal foot arch flattening among female runners, with a great deal of consistency between both feet, whereas results for the control group show asymmetrical medial arch shapes with right foot propensity to normal arch shape and left foot tendency for excessive arch.
The observed differences in feet arch shapes between female joggers and non-joggers indicate the influence of jogging on feet functional adaptations.
行走及其更快的形式——跑步，均由摆动和支撑这两个周期性相继的阶段组成；然而，它们在时间比例以及作用力大小方面存在差异。目前缺乏关于反复慢跑周期对足部功能的长期影响的研究，尤其是其对足弓形状的长期影响。
本研究的目的是回答定期慢跑是否会改变足部横弓和内侧纵弓形状这一问题。
研究材料包括96名平均年龄为26.57岁的女性，其中有50名经常慢跑的女性，以及46名不慢跑的女性。研究使用EMED-SF测力平台进行。根据卡瓦纳的方法，将足底分为10个区域，并确定每个区域的峰值压力和接触时间。定义了两个指标：根据坎塔利的方法确定的跖骨压力分布模式，以及根据卡瓦纳的方法确定的纵弓指数。
获得的数据显示，与不慢跑的女性相比，慢跑女性中位于中央的跖骨头下方出现最大压力（功能性足横弓缺失）的情况更为频繁。此外，研究结果表明，女性跑步者中内侧纵弓扁平的频率更高，且双脚之间具有高度一致性，而对照组的结果显示内侧足弓形状不对称，右脚倾向于正常足弓形状，左脚则倾向于高弓。
慢跑女性和不慢跑女性之间观察到的足弓形状差异表明慢跑对足部功能适应有影响。
