In a former article, we offered a definition of the sport tactics as an interpretative sport knowledge. The present article is a continuation of that deductive way that finally, having started from general study of the sport knowledge, marked up the phenomenon of the exclusive tactical interactions. The present article, then, intends to deepen and to justify the essential theoretical descriptors (understanding, interpretation and functional integration) that allow us to clarify the concept of tactics and the more frequent adjectives in the sport culture (Individual or Collective, Attack and Defense). The practical purpose of the theoretical analysis is to put the basis for a educational construction of the intelligence in sport interaction as well as basic didactic principles. As a part of the theoretical analysis it is also proposed a Functional Classification of the Sports based on the adjustative conventionalities and the different types of knowledge shown.<\/p>\n\n
