Currently, population of trail runners who run on non-flat surface is increasing to maintain their health and be fun. In trail running, there are many cases of running on various surfaces with slopes of different gradients, compared with usual running. Accordingly, it is predicted that trail running shoes require different functions from usual running shoes. Generally, high speed video and 3D motion capture system are used in an outside environment because there are fewer restrictions. However, in order to enhance the accuracy of designing, it is essential that mechanical information between shoes and ground be measured by using a force plate. The purpose of this study is to clarify fundamental functions for designing trail running shoes. In order to measure ground reaction force in various locations, a portable force plate is used. Then, ground reaction forces in down hill running, up hill running and flat running are compared. Furthermore, influence of sole stiffness to ground reaction force is also discussed.
