Sports associations are organizations that govern and promote specific sports at various levels, from amateur to professional. They establish rules, organize competitions, and support athletes and teams. Examples include the National Football League (NFL) for American football and the International Olympic Committee (IOC) for the Olympic Games. These associations also play a crucial role in developing the sport by providing training programs, resources, and funding. They often collaborate with schools, local clubs, and other organizations to encourage participation and improve the overall quality of the sport.
