Efimova made her international debut in 2007 at the World Cup, competing for Russia. Her most memorable sporting achievement came at the 2016 Olympic Games in Rio de Janeiro, where she won silver medals in the 100m and 200m breaststroke events.
Her father and coach, Andrey Efimov, has been the most influential person in her career. Efimova also looks up to US swimmer Michael Phelps and Russian swimmer Aleksandr Popov as her idols.
Efimova has faced several injuries throughout her career. After winning gold in the 50m breaststroke at the 2017 Russian Short Course Championships in Kazan, she had to withdraw from subsequent events due to an injury relapse. This also caused her to miss the 2017 European Short Course Championships in Copenhagen.
Efimova has received numerous awards and honours. She was named Sportswoman of the Year by the All Russian Swimming Federation in 2017. She was also named Female Swimmer of the Year by the Russian Swimming Federation in 2008, 2015, and 2016. For her achievements at the 2016 Olympic Games, she received the Order of Friendship of the Russian Federation.
Efimova became the first female swimmer representing Russia to win two medals at a single edition of the Olympic Games when she claimed silver in both the 100m and 200m breaststroke at Rio 2016. She also became the first female swimmer from Russia to win three Olympic medals with her bronze from London 2012.
Efimova's primary motivation is to win an Olympic gold medal. Despite having six world championship golds, she continues to compete with this goal in mind. She has stated that if she had won an Olympic gold earlier, she might not have continued swimming for so long.
In late 2013, Efimova tested positive for dehydroepiandrosterone (DHEA) during an out-of-competition test. She claimed that she unknowingly ingested the substance through a supplement purchased in the USA. A FINA doping panel found her negligent but considered subjective factors unique to her situation. She was suspended for 16 months from October 2013 to February 2015.
Apart from swimming, Efimova enjoys spending time with her dog Jasper, surfing, and snowboarding. These hobbies provide a balance to her intense training schedule.
Yuliya Efimova continues to be a significant figure in swimming with numerous accolades and a relentless pursuit of excellence. Her journey reflects dedication and resilience as she aims for new heights in her career.
