Abstract
At the landing in court game vibrations with various higher frequencies are excited. The range of the frequencies is entirely different from that in running It was clarified these vibrations produced some resonance in human body and made a bad influence on players' performance. The purpose of this study is an establishment of designing guide for court category shoes to eliminate the above resonance. By using a vibration control system, body vibration was firstly measured under the various input conditions. Through these measurements, the relationship between loading head and human body vibrations was confirmed. Secondary the effects of midsole insertion on human vibration were investigated under the above input condition. Therefore it was concluded that the midsole structure and hardness could control the human vibration to prevent the local body resonance.
