100-meter backstroke race

The 100-meter backstroke is a competitive swimming race where athletes swim on their backs, alternating arm movements and using a flutter kick. This stroke is the third fastest of the four main swimming strokes. Competitors start in the water, holding onto handles, and can remain underwater for up to 15 meters after the start and each turn. The backstroke was introduced into competition in the 20th century and has been an Olympic event for men since 1900 and for women since 1924, with races typically held at 100 and 200 meters, and 50 meters at world championships.12
