A9 (classification)

A9 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 combination of amputations of the upper and lower extremities. Their amputations impact their sport performance, including energy costs, balance and potential for overuse of muscles. Sports people in this class are eligible to participate in include athletics, swimming, sitting volleyball, amputee basketball, lawn bowls, sitzball and wheelchair basketball.

A9 is an amputee sports classification for people who have a combination of amputations of the upper and lower extremities. In competing in some sports, this class may have a different name:

F44, F56, F57, F58

Lawn bowls: LB1, LB2.

Sitting volleyball: Open.

Sitzball: Open.

Ten-pin bowling: TPB8, TPB9.

Wheelchair basketball: 2 point player, 3 point player, 4 point player.

The nature of a person's amputations in this class can effect their physiology and sports performance. Because of the potential for balance issues related to having an amputation, during weight training, amputees are encouraged to use a spotter when lifting more than 15 pounds (6.8 kg). Lower limb amputations effect a person's energy cost for being mobile. To keep their oxygen consumption rate similar to people without lower limb amputations, they need to walk slower. Because they are missing a limb, amputees are more prone to overuse injuries in their remaining limbs. Common problems with 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.
