The Slovenian star produced an impressive series of performances at the Mubadala Arena in the United Arab Emirates.

Trstenjak progressed to the semi-final stage of the women's under 63 kilogram competition, where she clinched a victory by ippon over Venezuela's Anriquelis Barrios.

The victory saw Trstenjak progress to the gold-medal match against Cuba’s Maylin Del Toro Carvajal, who had beaten Mexico's Prisca Awiti Alcaraz in the last four.

Olympic champion Trstenjak saw off the challenge, clinching victory with an ippon score.

Bronze medals were earned by Brazil's Ketelyn Quadros and China's Yang Junxia, after they overcame beaten semi-finalists Awiti Alcaraz and Barrisos, respectively.

The women's under-70kg final saw an all-Dutch contest between Kim Polling and Sanne Van Dijke.
