Nearly 100 participants from 30 regions of the country will gather to compete at the Sports Palace in the Moscow State University of Civil Engineering.

Medals will be competed for in a total of 18 categories; nine men’s and nine women’s.

"In spite of having vision problems, sambo wrestlers demonstrate high level of skills," Roman Novikov, head of the commission for sportspeople with limited health capacities in All-Russian Sambo Federation, said.

"Loss of vision is not an obstacle for using all means of sambo technique."

Preliminary fights will precede title fights on both days of action.  

Helmets which can be used in visually impaired sambo competitions were put through their paces at an international exhibition in Moscow last month.

The demonstration took place at the "Sport" event in the Russian capital.

According to inventors, the helmets completely exclude the possibility of residual vision during bouts.

A club for visually impaired and blind sambists was recently opened in Russian city Tyumen.
