Both Vladimir Maksimovitch Shevchuk and Evgeniy Vladimirovitch Ivashchenko were named as winners following a prize draw amid the flagship event in the Russian city.

Shevchuk won a dinner with sambo legend Fedor Emelianenko, a five-time world champion in the 100 kilograms division.

He learnt that he had won the prize on television and is a father to three sons who all practice sambo.

"I want my elder son to go and dine with Fedor, it was all done on his behalf," said Shevchuk. 

"As I was filling in the form I thought that if I become the lucky one, if I draw the prize, then Maksim's most cherished dream would come true. 

"I hope he meets Fedor and talks to him as soon as possible, I believe they've got things to discuss."

Ivashchenko's prize is a jacket signed by Emelianenko.

Russian dominated their home World Championships in Sochi, finishing on top of the medal table with 17 golds.

The three-day event ended on November 12.
