Tachikata たち型is a Japanese term for stances and lower body positions.
The basic requirements to improve one’s karate techniques are the correct body
position and balance. Powerful, accurate, smooth, and fast techniques can only
be delivered through stable and strong stances. One needs to maintain a firm
and stable position to execute a strong technique but not be rigid, and one
must be able to switch stances when required.
Stances can be categorized in three
ways: high and one-leg stance, middle high and lower, and the way the foot and
knees are used in aligning the center of gravity for stability. There are two
types of tension (inside and outside) used in middle and lower stances
measuring from the body’s centerline, e.g., Sanchin Dachi has the inside
tension and Shiko Dachi has the outside tension measuring from the center line
of the body.
Vital points to remember regarding the stances.
Soles: The ball of the foot or the full soles, or as per the
requirement of stance, must stay in complete contact with the floor, having a
strong grip.
Ankles: Ankles must be flexible and strong enough to bend and hold
the body weight.
Knees: It should sufficiently bend in the direction of the toes
maintaining the correct alignment.
Tension in legs (spreading): The legs should have proper tension inside or outside of
the center line of the body.
Position of Hips: Hips must be positioned correctly as per requirements with
correct body alignment.
Center of Gravity: To acquire stability and strength, one must lower the
center of gravity while maintaining correct body alignment. In addition, one
must also be able to tighten its hara/tanden (lower abdomen), or, in other
words, tighten the hara by contracting the muscles below the navel to the anus.
This will give stability, balance, and a strong stance, which can deliver
strong techniques.
Types of stances: – stance, one-leg
stance, middle high stance, middle stance, and lower stance. To take any
stance, one should understand the following principles: Lower the center of
gravity by bending your knee for a strong grip and stability with correct body
alignment. Proper tension in legs outside or inside as per the requirements of
stance.
