Abstract
The purpose of this study was to be found whether the ground contact motion is how to change when changing stage of running velocity. The subjects were the track and field club of 6 people in university. In this experiment, there was the shoe sole had been processed the thickness and inserted the sensor sheet which can measure the foot pressure. The subjects ran 10 to fifty-meters; subjectively increasing 10 stage of running velocity. The results were as follows. 1) With the increase running velocity, impulse in the ground contact were decreased. 2) With the increase running velocity, the ground contact time was shortened by the time until maximum 2 value was shortened. 3) After the ground contact, the center of foot pressure once moved rearward and then moved frontward. Also, with the increase running velocity, the moving distance from the rearward to the frontward was shorter gradually.
