Using a rotating training simulator to train rotational movements in aikido techniques

In martial arts and combat sports the techniques often involve rotational movements, both of the attacker and defen der. The competitors performing a rotational technique must properly guide their bodies by an adequate input of their own strength and properly use external forces of the rival. When spe cific movements are performed, the centre of gravity should be properly maintained for movement safety. A sudden loss of balance can result in falling, enabling the rival to take advantage of it. In literature there are no descriptions of devices that could prepare combat sports competitors for their body re sponse to rotational motion. The device should also help the competitor understand how the movements of particular body segments affect physical parameters reflecting rotational motion, such as angular velocity and centrifugal force. This paper presents the new equipment to be used for this purpose, namely the rotating training simulator [1]. Aikido is a martial art often involving rotational movements when fighting [2,3]. Biomechanical analysis explains that a proper performance of this movement by the defender allows taking advantage of the attacker’s strength [3]. The aim of this study is to present the potential of the rotating training simulator to teach/learn aikido techniques involving rotational movements.
