By the end of the 1950s, Musheghyan was one of the top featherweight wrestlers not only in the Soviet Union, but also in the world.

However, in spite of these successes the USSR national team coaching staff did not select him to partake at the 1960 Summer Olympics in Rome, after which Musheghyan retired from wrestling.

From 1971 to 1977 he worked in Afghanistan and Madagascar, after which he returned to coaching in Yerevan and participated in the organization of several tournaments in wrestling.

Musheghyan was also known in Armenia as an active public figure and founder of the "Zoravar Andranik" All-Armenian Union in 1986.
