Goalball was invented in 1946 by Austrian, Hanz Lorenzen, and German Sepp Reindle, in an effort to help in the rehabilitation of blinded war veterans.
The game was introduced to the world in 1976 at the Paralympics in Toronto, Canada and has been played at every Paralympic since. Every four years a World Competition has been held with the first being in Austria in 1978. Since that time the popularity of goalball has increased to where it is played competitively across the world.
Judo is a very popular sport for athletes with a visual impairment. It has featured in all five editions of the IBSA World Championships and Games and has been a Paralympic sport since the Seoul '88 games.
Judokas are split into weight categories while all sight classes - B1, B2, and B3 - compete together. The sport has proven very popular with athletes who have both visual and hearing impairments.
Women's judo was added to the Paralympic Games program for the first time in 2004 at the Athens games.
Over the last four years, the number of international athletes has increased rapidly. According to the current World Ranking List, there are more than 500 athletes from 4 continents and from almost 50 countries.
