Development of Muscle-Power Measuring and Training System by Utilizing Electric Dynamometer for Aged Senior

New measuring and training method of muscle power for senior age, that utilizes small 'electric generator' instead of conventional 'spring force', is described in this paper. Our study clarified that this method can measure not only the muscle power, but also the reflection time and the muscle strength without any physical stress on aged senior subject. Meanwhile, another advantage of employing electric generator is that generator can electrically produce regeneration resistance as the load for rehabilitation. This paper also describes whether the developed system can be applied for rehabilitation. With a view of physiotherapist, various investigations were executed. The evidences show the effects of the developed training method and the developed system.
