Research Abstract	The ordinary measurement method of muscle fiber composition by the muscular biopsy was performed only by the limited uses such as a study or clinical assay because of its invasiveness for patient's body and troublesome technique. Then, the new measurement method for muscle fiber composition which applied that tetanic stimulation frequencies were different from Fast-MU in Slow-MU was devised, and this usability was considered by the fundamental experimental experiment using animal. As the results, the change of muscle fiber composition during daily life such as aging, underexercising and muscle training was easily measured with low invasiveness. These results were presented at some conferences, and intended to submit some international journals.
