In each weight category, the competition consists of a single elimination tournament.
The winners of each contest qualify for the next round, with the two finalists going head to head in the gold medal contest.
All competitors who lose to one of the finalists at any stage of the competition enter the repechage. The two semi-final losers meet the winners of the two repechage pools; these matches determine the winners of two bronze medals.
