Isao Inokuma said that "Among the foreign judoists with brilliant shin-gi-tai (spirit, skill, and power) are the Soviet Union's Vladimir Nevzorov, the victor in the light-middleweight class in the Montreal Olympics, Dvoinikov of the Soviet Union, who was runner-up in the middleweight division at the same Olympics, and Dietmar Lorenz of East Germany, who won the 95-kilograms-and-under class in the Jigoro Kano Cup International Judo Tournament held in Tokyo in 1978".[2]
Dvoynikov is also a co-founder in 2016 with his son, a politologue and poet Valery Dvoinikov, of the Peter the Great's International Foundation working for the cultural reconciliation between Europe and Russia.[3]
