Associations or Organizations for sports business are extremely important when we try to gather information about a particular kind of sports. The associations represent a particular kind of sports or group of athletics. Not only do they act as a lobby group for policy making, but they are also responsible for raising awareness of some important issues and collecting data that can be used in your research.
