Liu Zige

Liu Zige (, born March 31, 1989) is a world record holding professional swimmer from China.

She made her international debut at the 2005 World Championships, where she placed 20th in the 200 m butterfly at 2:14.25.

She progressed steadily afterwards, and prior to the Olympics, her best time was 2:07.76, from the Chinese Olympics Trials.

Liu, nicknamed "Lucy," spent some time training under Jessicah Schipper's swimming coach, Ken Wood, and Wood sold Schipper's training program to Liu's coach.

She swam for China at the 2008 Olympics, where she won the women's 200m butterfly in a new world record of 2:04.18.

She won the women's 200 m butterfly Gold medal at the 2008 Summer Olympics in Beijing.

In the final, she clocked a time of 2:04.18, breaking Jessicah Schipper's world record by over 1 second, and won China's only gold medal in swimming at the Games.

Her teammate, Jiao Liuyang, took the silver in 2:04.72, also under the former world mark.

Schipper took the bronze in 2:06.26.

Liu's win was considered a big upset, as she was relatively unknown prior to the Beijing Games.

She would eventually beat Schipper and broke her world record in 200 meter butterfly during the 2008 Summer Olympics.

In 2009, Liu regained the 200m butterfly world record from Schipper at the Chinese National Games, with a time of 2:01:81 to win the gold medal.

She later added the short course world record at the World Cup in Stockholm (2:02:50).

She then even shortened that time in the next meet at Berlin with the time of 2:00.78.
