Individual style of behavior of sportsmen in single combat must not be determined exclusively in terms of tactics. The latter is just one manifestation of the individual style. Observation of the combat behavior of judo wrestlers makes it possible to distinguish in it its invariant part (structure) and all kinds of its situation-produced realizations (form). Depending on a particular structure possessed by a given sportsman his individual style is characterized either by high variability and the capacity for tactical reorganization (so-called basic style) or by a trend to look for standard conditions of behavior (compensatory style).
