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

Andrzej Mroczkowski
2013 Journal of Combat Sports and Martial Arts  
Using the rotating training simulator eliminates the error of excessive horizontal head and trunk tilt during ryokatadori kokyo nage performance in randori style.  ...  Using the training simulator resulted in a more effective shortening of the circle radius where the practitioners moved, thus increasing the value of the centrifugal force acting on the attacker.  ...  The dynamics of the ryokatadori kokyo nage technique, selected for the study during the attack of several competitors while performing randori is based on using the attackers' speed.  ...
