Biathlon was introduced in Innsbruck in 1988 for athletes with a physical impairment, and in 1992, athletes with a visual impairment also became eligible to compete.
The events consist of a 2.0 or 2.5 km course skied three or five times in the free technique for a total race distance between 6-15 km. Between the two stages athletes must hit two targets located at a distance of 10m. Each miss is penalised by an increase in the overall route time. The most important success factor lies in the capability of alternating the skills of physical endurance and shooting accuracy during the competition. Athletes with visual impairment are assisted by acoustic signals, which depending on signal intensity, indicate when the athlete is on target. The sport is governed by the IPC with co-ordination by the World Para Nordic Skiing Technical Committee following the modified rules of the International Biathlon Union (IBU).
Cross country skiing
Cross-country skiing first appeared at the 1976 Winter Paralympic Games in Örnsköldsvik, Sweden. The competition is open to athletes with a physical impairment and blindness/visual impairment. Depending on functional impairment, a competitor may use a sit-ski, a chair equipped with a pair of skis. Athletes with visual impairment compete in the event with a sighted guide. Male and female athletes compete in short distance, middle distance and long distance (ranging from 2.5km to 20km) or participate in a team relay using classical or free techniques. Cross-country skiing is governed by the IPC with co-ordination by the World Para Nordic Skiing Technical Committee following modified rules of the International Ski Federation (FIS) and is practiced by athletes in 24 countries.
Rifle: The rifle shall be any type of air or CO2 rifle of conventional appearance with a five shot clip and in accordance with specifications of the International Union of Shooting's (U.I.T) rule. For Blind class the rifle will be equipped with electro-acoustic glasses (optronic system).
Blind athletes are shooting with an electronical rifle that allows aiming by hearing. The closer the rifle points to the centre of the target the higher the tone is. The different tones that occur when the rifle is moved, allows the shooter to find the exact centre of the target
Sit-ski: Some athletes with a physical impairment compete from a sitting position using a sit-ski, also called a mono-ski. As the name suggests, mono-skis have a specially fitted chair over a single ski. The chair includes seat belts and other strapping, as well as a suspension device to minimize wear and tear on the skier's body.
Ski: Made from fiberglass, classical skis are usually 25cm to 30cm taller than the height of a skier. They are light, weighing less than 0.45kg each; and narrow, with curved tips and a cambered midsection, which is thicker and arched. Free technique skis are about 10cm to 15 cm shorter for greater manoeuvring. They are also nominally stiffer and have tips that curve less than classical technique skis. The underside of both types of skis has a groove down the centre to keep the ski straight when going downhill.
Target: Biathlon uses metal drop-down targets of which consist of a white target face plate with five target apertures, behind which are five independently operating knock down, falling plate scoring targets. The scoring plates must be black. A hit must be indicated by the black target circle being replaced by a white indicator disc. The target size has a diameter of 30mm for visually impaired athletes (class B) and 20mm for athletes with a physical disability (class LW).
Cross-country skiing first appeared at the 1976 inaugural Paralympic Winter Games in Örnsköldsvik, Sweden. Men and women used the classical technique in all cross-country distances until skating was introduced by athletes at the Innsbruck 1984 Paralympic Winter Games. Since then, events have been split into two separate races: classical and free technique. The new technique, however, was not officially used in a medal race until 1992 in Albertville, France.
In 2016, the sports were renamed and rebranded from IPC Cross-Country Skiing and IPC Biathlon to Para cross-country skiing and Para biathlon. The International Federation, formerly known as IPC Nordic Skiing has been renamed to World Para Nordic Skiing.
