Kibadachi is a dachi unique to Shotokan Karate. In Kibadachi, the knees are pushed over the toes, and the upper body divides the dachi into two equal halves. When viewing Kibadachi from the side (either left or right), no width is seen and the toes are completely aligned with the body (facing forwards). The overall size of Kibadachi is roughly the same as that of Fudodachi and Zenkutsudachi and its width is approximately twice the distance between the shoulders.
The elasticity of the Adductor Longus (muscle) is evaluated in vertical placement of the knees on both legs. Also, contraction of the shin muscle – Tibialis Anterior – is another factor in strengthening the Kibadachi.
Also, another very important point to take into account when it comes to maintaining equilibrium in Kibadachi is that the Pelvis must be turned approximately 5 degrees upwards. This causes the thigh muscle – Quadriceps Famoris – to contract and act like a rope, connecting the centre of gravity with Tibialis Anterior used in Kibadachi.
