Parasports are sports played by people with a disability, including physical and intellectual disabilities. Some parasports are forms of adapted physical activities from existing able-bodied sports, while others have been specifically created for persons with a disability and do not have an able-bodied equivalent. Disability exists in four categories: physical, mental, permanent and temporary. At a competitive level, disability sport classifications are applied to allow people of varying abilities to face similar opposition. Etymology The term "parasports" arose as a portmanteau of the words paraplegic and sports. Though the sport has since included athletes of disabilities other than paraplegia, the term persists as a catch-all. Other terms for the concept include adapted sports, adaptive sports, disability sports, and disabled sports. The term Paralympic sports may also be used interchangeably with parasports, though technically this only refers to sports contested at the Paralympic Games. Organization and history Organized sport for athletes with a disability is generally divided into three broad disability groups: the deaf, people with physical disabilities, and people with intellectual disabilities.

Intellectual disability Sports for persons with intellectual disabilities began to be organized in the 1960s through the Special Olympics movement. This grew out of a series of summer camps organized by Eunice Kennedy Shriver, beginning in 1962. In 1968 the first international Special Olympics were held, in Chicago. Today, Special Olympics provides training and competition in a variety of sports for persons with intellectual disabilities. In 1986, the International Sports Federation for Persons with Intellectual Disability (INAS-FID) was formed to support elite competition for athletes with intellectual disabilities. This was established in contrast to the more participative, "sport for all" approach of Special Olympics. For a time, athletes with intellectual disabilities were included in the Paralympic Games. After a cheating scandal at the 2000 Summer Paralympics, where a number of athletes participating in intellectual disability events were revealed to not be
