Basic study on Sport Shoes Designing for Quickness

Abstract

In ball game sports, quickness is one of the most important abilities for players. Various methods to improve quickness are proposed in training scenes, and several studies which focused on athletes’ posture with taking one step motion supposed to quickness have been reported. The purpose of this study is to get basic knowledge to design shoe structure producing quickness required in ball game sports. Two females and one male participated in this study and a target motion is a sprint movement in the front direction from the standing position under five different foot conditions (Normal, Plate Toe, Plate Heel, Tow down and Toe up). Ground reaction force and passing times on 3m and 5m were measured, and influences of the conditions on the quickness performance were investigated from viewpoints of GRF and COP trajectories. The results are as follows: (1) moving distance of COP and kicking time have negative correlation and (2) propulsion impulse in kicking time and transit time on 3m and 5m have negative correlation.
