Tai no Henko

Tai no henko Basic turning technique Kaicho Bruce Bookman

The application of Aiki in the technique demonstrated by Bruce Bookman is analysed below.

Analysis

At a time of 1.24 Uke grabs Tori's wrist with his right arm. Tori induces Uke to apply Aiki by lowering his wrist/body as he steps forward. This action causes Uke to momentarily relax his upper body and prepare his legs to extend upwards to resist the downward motion. By Uke extending his legs he causes the muscle torque about the foot joint of his front foot to be in the opposite direction to that required for him to resist Tori pulling him to the front by Tori bending his arm. Uke is unbalanced to the front. Aiki-Lead
