Sport has the capacity to unite nations and to bring people together. Even though the Soviet bloc ruled for over half of the twentieth century, the international order persists today. Nations are divided into core, peripheral, and semiperipheral blocs based on politics, economics, and culture. Typically, the core of the sports world includes the United States, Russia, Australia, and South Korea.

Emotions are a central aspect of the sports experience. They reflect athletes’ personal judgments about their own performances as well as their perceptions of others’ evaluations of them. These feelings may arise before, during, or after a performance. Certain sports are even governed by “feeling rules” to help athletes regulate their emotions appropriately. For example, players are often required to maintain proper behavior during the national anthem or during postgame victory celebrations.

Modern sports developed in the 19th century and were widely spread by the twentieth century. This phenomenon can be explained by the development of transnational cosmopolitan cultures, the creation of national sports organizations, and the standardization of sports rules. During this period, regular international competitions were established, and special competitions such as the Olympic Games were created.

The definition of sport is a complex one and varies across different disciplines. While some people define sport as a group or a competition, other people consider all forms of physical exercise to be a sport. However, these definitions do not necessarily reflect how participants engage in sport. Therefore, it is important to know what a sport is and to define it in an appropriate way.
