Jung Seul-ki

Jung made her first South Korean team at the 2006 Asian Games in Doha, Qatar. There, she won two bronze medals each in the 200 m breaststroke, and as a member of the nation's swimming team in the 4×100 m medley. Jung followed up her performance in the following year by winning the women's 200 m breaststroke crown at the 2007 Summer Universiade in Bangkok, Thailand. Jung's new meet record of 2:24.67 also dipped beneath the FINA A-cut (2:28.20) by more than four seconds, which assured her a spot on the South Korean team for Beijing 2008.

After excelling internationally in the 2006 and 2007 season, Jung competed for the South Korean swimming team in a breaststroke double at the 2008 Summer Olympics in Beijing. On the first half of a double, the 100 m breaststroke, Jung charged her way to the runner-up spot behind Italy's Roberta Panara in heat four with a steady 1:09.26, but missed the semifinals by almost a full second with a twenty-third overall placement. In her signature event, the 200 m breaststroke, Jung bounced back from the initial half of her specialty double to successfully grab the eleventh seed for the semifinals (2:25.95), but fell short on a berth for the top eight final by the following morning with a disappointing 2:26.83, matching her prelims position in the process.
