A8 (classification)

A8 is an amputee sport classification used by the International Sports Organization for the Disabled (ISOD).for people with acquired or congenital amputations. People in this class have one arm amputated below the elbow, but through or above the wrist joint. Their amputations impact their sport performance, including being more prone to overuse injuries. Sports people in this class are eligible to participate in include athletics, swimming, cycling, amputee basketball, amputee football, lawn bowls, and sitzball.

This class is for people who have one arm amputated below the elbow, but through or above the wrist joint. This classification is sometimes abbreviated as B/E. In competing in some sports, this class may have a different name:

Amputee football: Goalkeeper.

Badminton: STU5.

Lawn bowls: LB3.

Sitzball: Open.

Ten-pin bowling: TPB10.

The nature of a person's amputations in this class can effect their physiology and sports performance. Because they are missing a limb, amputees are more prone to overuse injuries in their remaining limbs. Common problems for intact upper limbs for people in this class include rotator cuffs tearing, shoulder impingement, epicondylitis and peripheral nerve entrapment.

This classification was set up by ISOD, with the current version adopted in 1992 and then modified in 1993. IWAS was created following the merger of ISOD and International Stoke Mandeville Games Federation (ISMGF) in 2005. Subsequently, IWAS became the classification governing body for some amputee sports.

For athletics competitions that use the IPC athletics classification system, this class competes in T46, F46 and T47. The extent of their below elbow amputation needs to be greater than a below wrist amputation or they are not eligible to compete in this class. The missing arm weight changes their running form by creating differences in rotation between hip and shoulder.

A study of was done comparing the performance of athletics competitors at the 1984 Summer Paralympics. It found there was no significant difference in performance in times between women in A6, A7 and A8 in the discus, women in A6, A7 and A8 in the shot put, women in the A6, A7 and A8 in the long jump, women in A6, A7 and A8 in the 100 meter race, women in A5, A6, A7 and A8 in the 100 meter race, men in the A3, A4, A5, A6, A7, A8 and A9 in the discus, men in A6, A7 and A8 in the discus, men in A1, A2, A3, A4, A5, A6, A7, A8 and A9 in the javelin, men in A6, A7 and A8 in the javelin, men in A8 and A9 in the shot put, men in A6, A7 and A8 in the high jump, men in A6, A7 and A8 in the long jump, men in A6, A7 and A8 in the 100 meter race, men in A7 and A8 in the 400 meter race, and men in A7 and A8 in the 1,500 meter race.
