Morihei Ueshiba

Morihei Ueshiba O-Sensei toys with a young Morihiro Saito in Iwama!

The application of Aiki in the Aikido techniques demonstrated by Morihei Ueshiba is analysed below. 

Analysis

In this video between the times 1.59 to 2.18 and 2.21 to 2.34 Tori applies Aiki by first offering the target to Uke and then, as Uke steps forward to make contact, he withdraws the target. This induces Uke to reverse the muscle torque about the ankle joint of his front foot to maintain his forward momentum to follow the target. This action unbalances Uke to the front. 


Analysis

In the video between the times 2.18 to 2.21 Tori applies Aiki by suddenly raising his arms as Uke steps towards him, inducing Uke to reverse the muscle torque about the ankle joint of his front foot in order to straighten his body to respond to a possible attack from above. This action causes Uke to maintain his forward momentum and become unbalanced to the front. Uke then falls over Tori's crouched body.
