T43 (classification)
T43 is a disability sport classification for disability athletics (track and jump events only), applying to athletes with "Double below knee amputation (or combined arm/leg amputation) or similar disability." It includes ISOD classified athletes from the A4 and A9 classes.
This classification is for disability athletics in the track and jump events. This classification is one of several classifications for athletes with ambulant related disabilities. Similar classifications are T40, T42, T44, T45 and T46. The International Paralympic Committee defined this class in 2011 as: "Double below knee amputees and other athletes with impairments that are comparable to a double below knee amputation." This includes athletes with loss of muscle power in the lower limbs consistent with Class F57 or F58." The International Paralympic Committee defined this classification on their website in July 2016 as, "Lower limb affected by limb deficiency, leg length difference, impaired muscle power or impaired range of movement".
People who are amputees compete in this class, including ISOD A9.
This class competes in T44. Shank length for people in this class is not uniform, with competitors having different lengths of leg found below their knee. People in this class use a prosthetic limb when competing in athletics. It has three parts: a socket, a shank and a foot. People in this class can use standard starting blocks because their amputation generally allows for the use of a standard starting position. Use of a specially made carbon fibre running prosthetic leg assists runners in this class in lowering their heart rate compared to using a prosthetic not designed for running. Runners in this class can have lower metabolic costs compared to elite runners over middle and long distances.
Inside the class, shank length does not impact the distance that male long jumpers can jump. A study 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 A2, A3 and A4 in the long jump, men in A2, A3 and A4 in the high jump, men in A4, A5 and A6 in the high jump, and men in A1, A2, A3 and A4 in the 400 meter race.
Historically, because of low participation rates in men's T43 races, the class has been combined with the T44 class. The combined class was then called T44 and included both single and double below the knee amputees. There was a push in 2008 to avoid this happening because of a perception that double below knee amputees had a competitive advantage compared to single below knee amputees. Subsequent research related to results for men at the 2012 Summer Paralympics in London confirmed this to be the case for both the 200 meters and 400 meters.
The nature of a person's amputations in this class can affect their physiology and sports performance. People in this class use around 7% more oxygen to walk or run the same distance as someone without a lower limb amputation.
Members of the ISOD A9 class compete in T42, T43, T44, F42, F43, F44, F56, F57, and F58. The shank length of people in this class can differ dramatically, and is not uniform across the class.
