From the middle of the nineteenth century onward the school physical education of Japan was rapidly modernized, until by the beginning of the twentieth century it had caught up with the standard in the West. This important period covering half a century is called the Meiji Era (1868-1912). Hence we may say that this period played a very great part in the establishment of the modern physical education in our country.
The characteristic of the Radio-Telemeter lies in that it can reduce the mechanical disturbance (both in the method of activity and in space) which obstructs the muscular exercises to the least, and that it can measure the actual state of the exercises as they are. Therefore, it offers a very effective method of measurement in a series of studies which are concerned with the influence of the muscular exercise on the body and the change of conditions, and with methods of exercises. The author planned this study as they noticed that point. Fortunately, the author was helped by the people in the electronic engineering, and was able to obtain good results concerning the application of telemeter in the study of physical exercises, one aspect of the researches on the phenomena of the living body made with the telemeter. Here is the reports on them.
