Measurement of biomechanical properties by impact response (II) : Analysis of impact forces and application for evaluation of muscle contraction

Abstract

The authors have developed a handy-typed impact hammer for biometric use and constructed an impact response measurement system. In this study, the loading period of an impact force is defined and examined the relation with the wave-height, which is the maximum value of an impact force. The relation between the contraction of muscle and the biomechanical properties measured from skin surface is also examined by using wave-heights, Ioading periods, and IEMGS. As a result, the sufficient correlation between these two is con-firmed.
