Zolnir defeated Xu Lili of China in a combative final where both fighters were almost constantly on the offensive. Zolnir managed to throw Xu once in the match's first minute, which was ultimately enough to win.
The 31-year-old Zolnir was one of the oldest competitors in the division. She won a bronze at the Athens Games and came seventh at Beijing. Zolnir focused mainly on grappling techniques on Tuesday, pinning down her opponents throughout the day.
The bronze medals were won by Yoshie Ueno of Japan and Gevrise Emane of France.
