Abstract
Authors are developing DVR that can do strength training in more places per one that can easily train everyone by even staying at home especially aiming at the senior citizen's independent walking maintenance. Because this DVR generates the load instead of the weight electrically, it is lighter than the past one. By the way, man can not show the same muscular power while operating. It necessarily is effective and not efficient to add a constant load while operating for man. There is a possibility to be able to train effectively if the load can be dynamically changed while operating. Then, because the mechanism and the control system that was able to use the resurrection brake in this research, and to operate a dynamic load were designed, it reports.
