Sensei Sunadomari 1985 Aikido Friendship Demonstration - Aikido Journal
The application of Aiki in the techniques demonstrated by Kanshu Sunadomari is analysed below.
At a time of 0.46, Tori extends his fingers as Uke comes to grab Tori's wrist. After Uke grabs Tori's wrist, Tori contracts his wrist by forming a fist, inducing Uke to relax his arm/upper body. Tori bends his arm at the elbow inducing Uke to follow Tori's wrist by rising onto his toes. This action has induced Uke to apply Aiki and become unbalanced by reversing the muscle torque about his front foot joint so as to lift his heel as he pulls back. Aiki-Lead
