For centuries sports brought the highest qualities of humanity - kindness, openness, tenacity, friendship, and teamwork. Sports help overcome difficulties and improve spirit. Many books and movies are produced to express and emphasize the role of sports in society. Many of them tell a wonderful story about the lives and achievements of individual athletes and teams that motivate people of the same generation and future generations. Over the centuries this movement has tied people and the country, encouraged mutual understanding and encouraged conflict resolution.
One of the most famous games in history, often called "blood of water", is the semi-finals of the Hungarian and Soviet Summer Olympics held in Melbourne in 1956. When the players quit the game, the Hungarian revolution began and the Soviet troops repressed the rebellion. Before the last end of the game was canceled, Hungarians defeated Soviets 4-0 to prevent angry Hungarians from reacting to the influence of Valentin Prokopov against Walven Zord. Since 1973 every two to four years, the men's water world world championship has been held at the FINA World Swimming Championship. A women's water polo team joined in 1986. Since 1979, the second championship series FINA Waterball World Cup has been held every other year. In 2002, FINA organized FINA Water World Alliance, the first international league of sports.
The Olympics were questioned at the Summer Olympics and the Winter Olympics. The 2016 Summer Olympics includes 28 sports, the other 5 sports are included in the 2020 Summer Olympics, and the 2014 Winter Olympics includes 7 sports. The number and type of events may differ slightly from the Olympic Games. Each Olympic movement is represented by an international governance body, the International Federation (IF). The International Olympic Committee (IOC) establishes a hierarchy of sports, disciplines and activities. According to this level, each Olympic movement can be subdivided into several areas, which are often misunderstood as unique sports. For example, swimming and water polo, they are actually areas of water sports (represented by the International Swimming Federation), figure skating, speed skating, they are all subjects of skating (represented by the International Skating Federation).
