娜斯佳·柳金

　　Anastasia Valeryevna"Nastia" Liukin (/?lju?k?n/; Russian: Анастасия"Настя" Валерьевна Люкина [?l??k??n]; born October 30, 1989) is a Russian American former artistic gymnast. She is the 2008 Olympic all-around champion, a five-time Olympic medalist, the 2005 and 2007 world champion on the balance beam, and the 2005 world champion on the uneven bars. She is also a four-time all-around U.S. national champion, winning twice as a junior and twice as a senior. With nine World Championships medals, seven of them individual, Liukin is tied with Shannon Miller for the third-highest tally of World Championship medals (among U.S. gymnasts).[4] Liukin also tied Miller's record (later equaled by Simone Biles) as the American gymnast having won the most medals in a single non-boycotted Olympic Games.[5]
