Belousova and Protopopov became Olympic champions for the second time at the 1968 Winter Olympics. At 32 and 35 years old, respectively, they were among the oldest champions in figure skating. The following season, they won the silver medal at the European Championships and bronze at the World Championships as Irina Rodnina began her reign with her first partner, Alexei Ulanov. Those were the pair's final appearances at major international competitions but they continued to compete within the Soviet Union until 1972.
