Abstract (in Japanese) (See Japanese page) 
(in English) A piezoelectric accelerometer is generally used for the measurement of MMG (mechanomyogram). As body movement causes a large artifact, the body fields being measured must be fixed securely. When MMG measurement is applied to healthcare such as clinical medicine or sport science, it is necessary to measure the MMG during involuntary body movement or exercise. The measurement of displacement-MMG is useful to examine the characteristics of muscle contraction, because the continuous enlargement deformation of muscle as shown in tetanus can be observed by this method. In this study, displacement-MMG transducer was newly developed, which was resistant to artifacts caused by involuntary movement and could be used to obtain measurements under exercise. Using this transducer, displacement-MMG of a single twitch following electro-stimulation was measured during exercise on an ergometer and while jogging on a treadmill.
