Koichi Tohei

Reviving Koichi Tohei's Ki Aikido Curriculum

The application of Aiki in the technique demonstrated by Koichi Tohei is analysed below

Analysis

In this video, at the time of 2.42, Tori is threatened with a knife. Tori pivots about his front foot and induces Uke to apply Aiki, to unbalance himself, by pressing downwards on Uke's  knife arm. This induces Uke to push upwards by reversing the muscle torque about his front foot joint, so his heel rises, causing him to become unbalanced to the front due to his forward momentum. Aiki-Feint

Ki Aïkido - Koichi Tohei

The application of Aiki in the technique demonstrated by Koichi Tohei is analysed below

Analysis

In this video, at the time of 15.07, Tori is held by his jacket. Tori induces Uke to apply Aiki by lowering his weight which induces Uke to push upwards by lifting his heel(s) as Uke is pulled to the front.  Consequently, Uke becomes unbalanced to the front due to the muscle torque about Uke's foot joints being in the opposite direction to that required to resist being pulled to the front.  Aiki-Lead
Tori applies the atemi to deter Uke from stepping forward with his left leg to regain his balance.

Koichi Tohei - Ki Aikido 2/5 Fundamental Concept Principle   

The application of Aiki in the technique demonstrated by Koichi Tohei is analysed below

Analysis

At a time of 7.33 Uke holds Tori's wrists. Tori's downward movement induces Uke to momentarily relax his upper body and to prepare his lower body to pull upwards by extending his legs. Consequently, the muscle torque about Uke's foot joints, due to him extending his legs, are in the opposite direction to that required to resist Tori moving his wrists/body to the side. Uke is unbalanced to the side. Aiki-Lead
