ATC code H01 Pituitary and hypothalamic hormones and analogues, a subgroup of the Anatomical Therapeutic Chemical Classification System statistical category of eyelid inflammations
H1 is a Paralympic cycling classification. The UCI recommends this be coded as MH1 or WH1.
PBS defined this classification as "Handcycle 1 (H1) is for athletes with severe loss of trunk stability and leg function, and severely impaired upper limb function." In 2012, UCI defined this classification broadly as: "Tetraplegia C6 or above and severe athetosis / ataxia / dystonia".The Telegraph defined this classification in 2011 as "H 1-4: Athletes on handcycles, with lower limb dysfunctions and limited stability"
This classification can use an AP2 recumbent, which is a competition cycle that is reclined at 30 degrees and has a rigid frame. This classification can also use an AP3 hand cycle which is inclined at 0 degrees and is reclined on a rigid competition frame.
Cycling first became a Paralympic sport at the 1988 Summer Paralympics. In September 2006, governance for para-cycling passed from the International Paralympic Committee's International Cycling Committee to UCI at a meeting in Switzerland. When this happened, the responsibility of classifying the sport also changed.
