The main bracket consisted of a single elimination tournament, culminating in the gold medal match. Two bronze medals were awarded at the taekwondo competitions. A repechage was used to determine the bronze medal winners. Every competitor who lost to one of the two finalists competed in the repechage, another single-elimination competition.
