world of international sports has a hierarchical structure whereby participation of a country’s team in any international event is governed by the concerned International Federation and participation in multi–disciplinary events is governed by the IOC. World Level Association/Federation/Bodies exist in every sport, which are affiliated to IOC. At the national level, there is IOA, corresponding to the International Olympic Committee.
Its affiliating organizations are NSFs, one for every sport; these also affiliate to their respective World/Association/Federation/Body, and are recognized by them. In the absence of such affiliation or recognition, no player can compete in any international tournament or competition.
