Explosive Techniques of Aikijujutsu Bernie Lau


The application of Aiki in the Aikijujutsu techniques video by Bernie Lau is analysed below. 

Analysis

In the video, at a time of 00.00, Uke attacks with an overhead strike with a knife. Tori steps towards Uke and blocks Uke's arm. Tori then presses down on Uke's attacking arm whilst pushing it sideways with his other arm. This action induces Uke to apply Aiki, as he is pushed to the side, by reversing the muscle torque about his front leg foot joint to push upwards against the downward force on his attacking arm. Consequently, Uke is unbalanced to the side by the contact reaction force he experiences due to Tori pushing his arm to the side. 

Analysis

In the video, at a time of 01.04, Uke attacks with a strike to the side of Tori's head with a knife. As Uke steps forward with his right leg, Tori steps forward and applies an upward atemi to Uke's face. This action induces Uke to apply Aiki, as his momentum falls onto his right foot, by reversing the muscle torque about his right leg ankle joint to straighten his body to minimise the upward impact of the atemi.  Consequently, Uke is unbalanced to the front by his own momentum. 

Analysis

In the video, at a time of 01.50, Uke attacks with an overhead strike to Tori's head with a knife. Tori steps forward to block Uke's attacking arm with his right arm. On contact,Tori applies Aiki by reversing the muscular torque about his right shoulder joint so as to rotate the contact point upwards about his shoulder joint. Consequently, Uke is unbalanced to the front by his own attacking force. 

Analysis

In the video, at a time of 04.04, Uke attacks with a hand strike to the side of Tori's head. Tori blocks Uke's attacking arm with his left arm. On contact,Tori applies Aiki by reversing the muscular torque about his rear foot so as to rotate the contact point sideways about his rear foot. Consequently, Uke is unbalanced to the side by his own attacking force. 

Analysis

In the video, at a time of 04.54, Uke attacks by grabbing Tori's neck with both hands. Tori applies an atemi to Uke's solar plexus. This action induces Uke to apply Aiki, as he pulls with his arms, by reversing the muscle torque about his waist joint to bend forward so as to minimise the impact of the atemi. Consequently, Uke is unbalanced to the front by the contact reaction force due him pulling.
