Alina Maratovna Kabaeva

At the 2001 World Rhythmic Gymnastics Championships, she won the gold for the ball, clubs and rope, and gold in the Individual All-Around and hoop. At the 2001 Goodwill Games in Brisbane, Australia, Kabaeva won the gold for the ball, clubs and rope, and the silver in the Individual All-Around and hoop. However, Kabaeva and her teammate Irina Tchachina tested positive to a banned diuretic (furosemide) and were stripped of their medals.
Irina Viner, the Russian head coach, who also served as the Vice President of the FIG Rhythmic Gymnastics Technical Committee at the time, said her gymnasts had been taking a food supplement called "Hyper" which contained mild diuretics, which, according to Viner, the gymnasts were taking for pre-menstrual syndrome. When the supply ran out shortly before the Goodwill Games, the team physiotherapist restocked at a local pharmacy. According to Viner, the supplement sold there was fake and contained furosemide. The commission requested the Goodwill Games organizing committee to nullify Kabaeva and Tchachina's results. The FIG also nullified their results from the World Championships in Madrid, causing Ukraine's Tamara Yerofeeva to be declared the 2001 World Champion.
In 2003, Kabaeva marked her return to competitive gymnastics after the ban, she won the all-around gold medal at the 2003 World Championships as well as the event final in ribbon and ball ahead of Ukrainian Anna Bessonova.
In 2004, she won the all-around gold at the 2004 European Championships in Kiev. At the 2004 Athens Olympics Kabaeva took home the gold medal in the individual all-around for rhythmic gymnastics with a score of 108.400 (Hoop 26.800, Ball 27.350, Clubs 27.150, Ribbon 27.100), the silver medal went to her teammate Irina Tchachina.
