There are three main types of fiber created by fixed cells, which are collagenous, elastic, and reticular. These fibers help make up the matrix of several connective tissues, such as areolar, or loose connective tissue, and fat, or adipose connective tissue. Wandering cells move throughout the connective tissue matrix.
Perhaps the most important aspect of kendo is footwork (ashi sabaki). The footwork most frequently employed in kendo is generally of a type called suriashi, or rubbing feet. What this means is that your feet should rub along the floor as you go. Do not lift your feet from the floor, but rather slide them in a kind of shuffle step.
Tsuki is one of the five target areas (datotso-bui) in kendo (along with men, do, hidari kote and migi kote). It is a thrust of the point of the shinai to the throat. Unlike most other martial arts that use this term, in kendo, tsuki is a comprehensive term for both the movement and the target.
