Career
Korolev joined the State Committee for Sports and Physical Education in 1954, and began a career of educating athletes and coaches. From 1962 to 1974, he lectured at the State Committee for Sports and Physical Education and became its senior lecturer. He served as the head of the hockey department at the State Committee for Sports and Physical Education from 1974 to 1983, and was the head teacher of its school of hockey coaches. From 1983 to 1989, he was the head coach of the football and ice hockey committee of the All-Union Council on Physical Culture and Sports, and was the deputy of the council from 1987 to 1988. Korolev was also connected to both the Soviet Union national ice hockey team and the Soviet Union national junior ice hockey team. From 1964 to 1992, he was head of the research group for the national men's team, and contributed to the team winning seventeen Ice Hockey World Championships and seven Winter Olympic Games gold medals. At the end of his tenure, he was head coach of the national team from 1990 and 1992. At the 1987 World Junior Ice Hockey Championships, the Soviet juniors had a bench-clearing brawl versus the Canadian juniors, that later became known as the Punch-up in Piestany. Korolev expressed regret that the incident occurred but did not admit any guilt. He felt that the game should have been finished instead of both teams being disqualified from the tournament. During ice hockey at the 1990 Goodwill Games, Korolev spoke out against Sergei Fedorov leaving the Soviet national team and signing a five-year contract with the Detroit Red Wings. Korolev insisted that his player was stolen by premeditated actions and, rather than defecting on his own "under normal circumstances". He said that "having this happen on the eve of the goodwill games, is like a spoon of tar in a barrel of honey". Korolev retired from coaching then served as vice-president of the Ice Hockey Federation of Russia from 1992 to 2001, and as its secretary general from 2001 to 2003. He also represented Russia at international meetings, and was elected to the International Ice Hockey Federation Council in 1992. He served for six years until 1998 as the chairman of its coaching committee. Korolev has served as a director of the hockey department at the International Scientific and Methodological Center since May 2003.
