Support for Building Instantaneous Motion Utilizing Free-fall Motion of Body Center of Mass

Abstract

A great deal of attention has been paid for effectiveness of instantaneous motion utilizing free-fall motion of body center of mass in sports. Previous research demonstrated that this motion is quicker and could push forward stronger compared with general motion. There was a lot of research into the effectiveness of instantaneous motion utilizing free-fall motion of body center of mass. However, a little research into how people build this motion was established. This research had focused on learning process of this motion and how to support for building instantaneous motion utilizing free-fall motion of body center of mass. The three approaches, focused on a sense of moving body center of mass, the moment of extending a hind leg and a gap between barycentric orbit and brachistorechrone curve, were employed to resolve the difficulties of building the motion and were applied to design support system for building the motion. This system could easily be carried and adjust physique differences. In addition, it has an enough strength structure for withstanding the impact during used. Then the process of building instantaneous motion utilizing free-fall motion of body center of mass using the machine was suggested.
