Shizuo Imaizumi's Ki Aikido Course: Katatori Ikkyo

The application of Aiki in the technique demonstrated by Shizuo Imaizumi is analysed below.

Analysis

Tori takes a small step forward with his right foot that induces Uke to push backwards with his right arm. Tori goes with Uke's push by stepping backwards with left leg. As Uke steps forward, Tori applies an upward atemi that induces Uke, to apply Aiki, by reversing the muscle torque about the ankle joint of his right leg so as to minimise the impact of the atemi by straightening his body. Uke becomes unbalanced to the front by his forward momentum. Aiki-Feint

Mechanics of Unbalancing Uke using Aiki

Analysis

Initially, Tori is just being held by his wrists. Tori then extends his left arm and moves with his body weight downwards and towards Uke's rear. Uke unable to stop the force of this movement, without becoming unbalanced, relaxes his upper body allowing his right arm to follow Tori's left arm whilst preparing his lower body to pull upwards by extending his legs. Consequently, Uke is unbalanced to the rear using Aiki by the muscle torque about Uke’s ankle joints being in the opposite direction to that required to resist Tori’s push to the rear with his right arm.

Shizuo Imaizumi's Ki Aikido Course: Katate Kosa Tori Irimi Nage

The application of Aiki in the technique demonstrated by Shizuo Imaizumi is analysed below.

Analysis

As Tori steps to the side, Uke momentarily relaxes his arm to avoid becoming unbalanced to the side and to allow him to realign his hips in preparation to pull back in the sidewards direction. As Uke relaxes his arm, Tori rotates Uke's wrist so that it becomes locked which induces Uke to apply Aiki by reversing the muscle torque about the foot joint of his front leg as he pulls. This action unbalances Uke. Aiki-Lead
