步行可說是一項最簡便的運動，但長時間的行走對足部反而是一種累積性的負荷，極易發生疲勞性問題，因此有效分椷步行時的足底壓力分佈確有其重要性。本研究以六名下肢無受過嚴重傷害之國立體育學院男性大專生為受試者（24.0±2.3歲，172.3±2.3cm，66.8±2.9kg），使用EMED-Pedar足底壓力測量系統擷取在70、90、110、130與150m/min之行走速度下受試者足底各區塊（外足跟、內足跟、外足中、內足中、其他蹠骨、第一蹠骨、拇趾及其他腳趾區）之最大對地作用力（MF）、最大足底壓力（PPP）、力量-時間積分值（FTI）及壓力-時間積分值（PTI），並以SPSS 8.0軟體分別針對九個區塊在五種不同步行速度下的四個數值進行單因子重複量數變異數分析，結果如下： 1. 在最大對地作用力（MF）方面：在不同速度下，除了外足中、其他蹠骨與其他腳趾區外，其他區域皆有顯著差異（P<.05）的情況產生。其中全足、內足跟、外足跟、內足中與拇指區之受力是隨速度增加而增加，而第一蹠骨區受力則隨速度增加而減少。 2. 在最大足底壓力（PPP）方面：在不同速度下，除了外足中、第一蹠骨及其他腳趾區外，其他區域之數值皆有顯著差異（P<.05），且隨著速度增加而增加。 3. 在壓力-時間積分值（PTI）方面:在不同速度下，僅有外足中、第一蹠骨與其他蹠骨有顯著差異（P<.05）的情況產生，且三者之數值是隨速度增加而減少。 4. 在力量-時間積分值（FTI）方面：和各區塊壓力-時間積分值（PTI）可同，僅有外足中、第一蹠骨和其他蹠骨有顯著差異（P<.05），且數值是隨速度增加而減少。

　　　　　Walking is an easy and popular exercise. But foot will bear too much and fatigue after human body walking for a long time. So analyzing foot pressure when we are walking is necessary. In this study, six health undergraduates without serious lower extremity injuries served as subjects (24.0±2.3 years, 172.3±2.3cm, 66.8±2.9kg). Foot was divided into external hind-foot (EHF), internal hind-foot (IHF), external mid-foot (EMF), internal mid-foot (IMF), first metatarsal (FM), other metatarsal (OM), great toe (GT) and other toes (OT) areas. EMED-Pedar Foot Pressure Measuring System was used to collect maximum force (MF), peak plantar pressure (PPP), pressure-time integral (PTI) and force-time integral (FTI) parameters when each subjects walked in five velocity (70, 90, 110, 130 and 150m/min). In each foot area, one-way ANOVA formula in SPSS 8.0 statistic software was used to compare each parameter in different walking velocity. Result were as follows: Unless EMF, OM and OT, MF were different significantly (P<.05) in different walking velocity and bigger by the increasing of velocity in the whole foot, EHF, IHF, IMF and GT. In FM, MF was lesser by the increasing of velocity. Besides EMF, FM and OT, PPP were different significantly (P<.05) in different walking velocity and bigger by the increasing of velocity in other foot areas. PTI were different significantly (P<.05) in different walking velocity and lesser by the increasing of velocity in EMF, FM and OM. Having the same results with PTI, FTI were different significantly (P<.05) in different walking velocity and lesser by the increasing of velocity in EMF, FM and OM.
