Para swimming has been a part of the Paralympic programme since the first Games in 1960 in Rome. The sport has become highly competitive and it is among the largest and most popular events in the Paralympic Games.
Male and female athletes with a physical, vision or intellectual impairment are eligible to compete. Athletes are classified based on their functional ability to perform each stroke.
World Para Swimming uses the same rules as its Olympic counterpart, World Aquatics, with some modifications where needed. Some athletes, due to the nature of their impairment, may be allocated certain exceptions in accordance with the World Para Swimming Rules & Regulations. For example, a swimmer with an arm amputation receives an exception to start on the backstroke event with one hand.
