| Research Abstract |
The aim of this study is to elucidate the characteristics of muscular function of elderly people to development of muscular function evaluating system. The electromanogram (EMG) and mechanomyogram (MMG) were used to evaluate the muscular function. The results were obtained as the following. (1) Total power and median power frequency of MMG power spectrum were influenced by age although both variables of EMG were not influenced by one. (2) For elderly people, the MMG amplitude was significantly increased depending on the endurance time of muscle in comparison with EMG amplitude. These results might be related to the muscular atrophy and the decreasing of fast muscle fiber by aging.
