Zhang Yufei (swimmer)

Zhang Yufei (born 19 April 1998) is a Chinese competitive swimmer who specializes in sprint freestyle and butterfly events. Considered one of the most promising swimmers in the international scene, she produced a tally of thirty-seven medals (eighteen gold medals, seven silver medals, and twelve bronze medals) in her swimming career, spanning the Youth Olympics, Asian Games, World Championships and the Summer Olympics. In 2023, she was named as the most valuable player in the women's division, in the 2022 Asian Games in Hangzhou.

Career
Born in Xuzhou (Jiangsu), Zhang began swimming at the age of four partly because of the encouragement and influence of her mother, who acted as her personal coach. Two years later, she started training professionally as a member of the Jiangsu Swimming Team, and eventually held numerous records for her age group. As more records followed, Zhang's rapid improvement culminated on her major debut in an international sporting event at the age of fourteen, when she beat 2008 Olympic champion Liu Zige for the gold medal in the 200 m butterfly at the 2012 FINA World Cup meet in Beijing. The following year, she was selected for China's national swimming team.

Zhang's international debut came as a member of the host nation China at the 2014 Summer Youth Olympics in Nanjing, where she achieved a total of five medals: three golds and two silver. Zhang started off the competition with a powerful butterfly split of 58.56 in the girls' 4 × 100 m medley relay that tremendously helped her Chinese foursome break the junior world record (4:03.58) for the gold medal. On the same night, she managed a strong swim to take the silver in the 200 m butterfly with a time of 2:08.22, finishing farther behind Hungary's Liliána Szilágyi by less than two seconds. In the girls' 4 × 100 m freestyle relay, Zhang posted a third leg split in 54.09 until her host nation's foursome celebrated again with another relay victory in 3:41.19. On 22 August, Zhang relegated to her second silver in the 100 m butterfly at 57.95, narrowly losing the race again to Szilagyi by almost three tenths of a second. Despite missing out her first individual gold, Zhang and her teammates Li Guangyuan, He Yun, and Yu Hexin powered their stretch to grab another relay title for the Chinese squad in the mixed 4 × 100 m medley (3:49.33).

One month later, at the 2014 Asian Games in Incheon, South Korea, Zhang set a 54.10 split on the third leg to put the Chinese squad ahead to a marvelous victory in the women's 4 × 100 m freestyle relay, with a time of 3:37.25.

At the 2015 FINA World Championships in Kazan, Russia, Zhang swam her two finals on the fifth night of the competition with forty minutes in between. First, she lowered her own junior world record with 2:06.51 to take home her individual bronze in the 200 m butterfly. Forty minutes later, Zhang set a third leg split of 1:58.73 to deliver the Chinese foursome a bronze medal in the women's 4 × 200 m freestyle relay with a combined time of 7:49.10.

On 22 August 2018, Zhang won the Women's 200 m butterfly gold medal at the 18th Asian Games in Jakarta, Indonesia with 2:06.61.

On 25 July 2021, Zhang went 55.64 to win silver in the Women's 100 m butterfly at the 2020 Tokyo Olympics behind Maggie Macneil, who went 55.59.

On 28 July 2021, Zhang broke the Olympic record and the world record in the Women's 200 m butterfly and the Women's 4 × 200 m freestyle relay respectively, winning the gold medals in both events.

On 24 July 2023, Zhang won the women's 100 m butterfly gold medal at the 2023 Fukuoka World Aquatics Championships.

At the 19th Asian Games in Hangzhou, Zhang topped the podium in the women's individual 50 m freestyle, 50 m butterfly, 100 m butterfly and 200 m butterfly, while also contributing to her national women's 4 × 100 m freestyle relay and mixed 4 × 100 m medley relay gold medals, securing 6 golds in all. In 2024, the New York Times alleged that significant levels of trimetazidine were detected in her blood stream prior to and during the 2021 Tokyo Olympic Games. During a press release, the World Anti-Doping Agency said that the levels of TMZ found in Chinese swimmers were not capable of producing any enhancement in performance at the concentrations found and were due to an environmental contamination.
