Abstract

The purpose of this study was to clarify the kinetic features of running motion associated with the change of the minimum value of arch height ratio. The subjects were seven male college students who had experience running 10km. By processing the shoes, deformation of the foot arch inside the shoe was measured. Kinematics and kinetics of the running motion were recorded for 5 conditions: In sequence (1) static standing posture, (2) 15 m running on the flat road, (3) 10 km running on the treadmill, (4) 15 m running on the flat road, (5) static standing posture. The results are presented for 3 contrasting subjects. 1) At the timing of the minimum value of arch height ratio (MAHR), inflection points were seen in the trajectory of COP. 2) At the timing of the MAHR, the joint torque around each axis of the ankle joint reached peak values. 3) It is considered that the running form and ankle joint torque at the timing of the MAHR affects the direction of toe off.
