Video - Prapawadee wins gold with record
Prapawadee Jaroenrattanatarakoon broke the Olympic record as she won the women's 53kg weightlifting.
South Korean Yoon Jin-hee claimed the silver with Nastassia Novikava of Belarus taking the bronze.
Thailand's Prapawadee lifted a total of 221kg, including 95kg in the snatch and an Olympic record score of 126kg in the clean and jerk.
Her total was 8kg better than Yoon and Novikava, with the former taking silver because of a lower body weight.
Prapawadee was previously known as Chanpim Kantatian, but changed her name in 2007.
"A fortune teller told me if I changed my name I would go far, so I changed it because I wanted to go to the Olympics," she told reporters after her win.
"Last time I didn't make it, and now I wanted to go in."
