A sport that has been present in the Olympics since the first edition, in 1896 in Athens, shooting took longer to be part of the Paralympic programme: its entry only happened in 1976 when the event was held in Toronto, Canada. Six years earlier, in Scotland, the discipline began to evolve.
Only men competed in the Canadian city, but in 1980, when the Paralympic Games were held in Arnhem, Holland, women participated in some mixed categories. In 1992, they were removed from the programme in Barcelona, and returned once and for all in the Atlanta 1996 Games, with events for men, women and mixed.
Over the years, the classification system also evolved. While in the beginning events were divided by the type of disability, nowadays athletes with different disabilities can compete in a single category. There are three main categories: SH1 (pistol and rifle shooters who do not require support for the gun), SH2 (rifle shooters who need support for the gun because they cannot hold it with their arms) and SH3 (rifle shooters with visual impairment).
In the Paralympic Games, only classes SH1 and SH2 are represented. Competitions follow the rules of the International Shooting Sport Federation (ISSF), but adapted by the International Paralympic Committee (IPC), which is responsible for the sport. There are several kinds of support equipment, such as shooting tables and chairs, as well as gun supports.
As in the conventional shooting competition, rules vary according to the event, distance, target type, shooting position, number of shots and time allowed for shooting. The target is divided into ten circles, with different point values - the centre circle, the smallest of all, is worth ten points. Whoever has the best performance in total points for the qualifying stage and the final is the winner.
