This  training note provides guidance on how to control the space when responding to a katadori attack (i.e. a single hand shoulder grab).  The video extract is from a class given by Peter Kelly Sensei (Aikido Yuishinkai) at our Dojo on 17 May 2014.

While the video extract deals specifically with a response to a katadori attack, the principles discussed and demonstrated are equally applicable to a wide range of other techniques where it is necessary for the uke to step to the rear.  Principles discussed include the correct foot positioning, maintaining forward energy, direction of centre and sinking/grounding.

In the context of sinking and grounding, Peter Sensei comments:

“Sinking/grounding is paramount in aikido as it represents the vertical plane. All aikido techniques have both a vertical and horizontal plane. This is what O’Sensei called the cross of Aiki.”
