Uchi-komi - Judo Development


What is Uchi-komi?

What is uchi-komi and which parameters can you as a coach change or manipulate to make the most out of it?

Uchi-komi means “make contact”, and it could be done either with a rubber band, a partner, two partners with a sprint between or with several partners.  In this exercise the tori tries to make the movement repeated, like stepping into a judo throw,  as a projection without throwing the opponent.  Through this exercise the placement of the body is trained, but also good timing in the technique, this due to making the body learn to adjust to the proper balance of the technique.  

The uchi-komi can then be further modified in thechniqual parts, movements, resistance and repetitions other than different choice of partner, see the model explaining parameters that can be modified or manipulated for uchi-komi.

A simple model showing parameters that can be modified or manipulated during uchi-komi.

Different modifications in Uchi-komi

The technical parts can be modified by how the stepping is conducted, is tori stepping in towards uke or stepping out away from uke. Is tori laying on the stomach or back and then standing up and conducting the technique. How does tori pull: up, forward, or down, how is the distance between uke and tori from the beginning is it tight or are there plenty of space, how is the gripp in the beginning: no gripp, standard gripp, 2 to 1 gripp etc.

Uchi-komi can also be teached in different movements like standing still, forward, backward, to the sides left/right, circular movement left/right or dynamic movement (all directions).

The exercise can also be adjusted in how many repetitions that are made after each other for example: every other time, 5 repetitions, 10 repetitions and so on can be modified to suit the training. 

Uchi komi can also be taught while uke is easy where the technique is easy to make, but the uke can also resist to make it much harder to make the technique more like the conditions of competition. It’s good as a coach to also adjust the resistance of uke, because different conditions can be good for different types of practices.
