National Olympic Committees (NOCs) are organizations responsible for overseeing the participation of their respective countries in the Olympic Games. Each NOC is tasked with promoting the Olympic movement, supporting athletes, and organizing national competitions. They ensure that athletes meet the eligibility requirements set by the International Olympic Committee (IOC). NOCs also play a crucial role in selecting the host cities for national trials and managing the logistics of sending athletes to the Olympics. They work closely with various sports federations to develop training programs and provide resources to help athletes succeed on the international stage.
