Originally, lightweight rowing was a introduced as a category at the 1996 Summer Olympics, due to countries with athletes of smaller average stature competing with an unfair disadvantage, as rowing favors taller athletes who have more leverage.
Current Olympic-class lightweight events in rowing are the men's lightweight double sculls, and the women's lightweight double sculls. From 1996 to 2016, there was also the men's lightweight coxless four event.
