The application of Aiki in the technique demonstrated Morihiro Saito is analysed below.
The techniques demonstrated for the first two minutes of this video all involve Tori stepping to the side of Uke's front leg whilst extending his arm on the same side. This movement of Uke's wrist to the side induces Uke to momentarily relax his arms/upper-body so as to reposition his body to resist this sideways movement by pulling back using the muscle torque about his ankle joint. Uke's arm is therefore extended to the side.
Whilst Uke's arms are relaxed, Tori crosses over his other arm to grasp Uke's extended arm at the wrist. As Tori crosses his arm over, Uke's wrist holding this arm is then bent backwards. This action induces Uke to apply Aiki by reversing the muscle torque about his ankle joint, in order to retain his grip on Tori's wrist as it crosses over. Consequently, Uke becomes unbalanced as he pulls back. Aiki-Lead
Morihiro Saito Sensei Ushiro Ryote Dori
The application of Aiki in the technique demonstrated by Morihiro Saito is analysed below.
In the techniques shown in this video Uke restrains Tori's wrists from the rear. Tori induces Uke to apply Aiki by slightly lowering his body/wrists as he bends his arms to the front. This action induces Uke to momentarily relax his upper body and to extend his legs in preparation to push upwards against Tori's wrists. Pushing upwards causes the muscle torque about the foot joint of Uke's front foot to be in the opposite direction to that required for Uke to resist Tori pulling him to the front. Uke is unbalanced to the front. Aiki-Lead
