[5] Dmitriyeva appeared internationally competing at the 2008 Kyiv World Cup winning the gold in juniors all-around.

Dmitrieva went to the 2009 World Championships in Mie as a part of the national team with Evgenia Kanaeva, Olga Kapranova and Daria Kondakova.

In the ball final she scored 28.650 to win the silver medal, finishing 0.050 points behind her teammate Evgenia Kanaeva.

She competed at the World Cup in Kyiv where she won a total of 4 gold medals in all-around and apparatus finals in clubs, hoop and ribbon ahead of Ukrainian Alina Maksymenko.

A foot injury led her to withdraw from the World Cup series in Tashkent and the selection for a 2012 European spot in the Russian national team.

The head coach of Russia, President of the Russian Federation of Rhythmic Gymnastics, Irina Viner said the question of participation in the Olympics remained open and would be resolved only after the June Grand Prix in Austria and the World Cup in Belarus in July.

Despite these results, Alexandra Merkulova was named as Russia's nominal second entry in rhythmic gymnastics, together with reigning 2008 Olympic Champion Evgenia Kanaeva.

Viner stated that the final decision was yet to be confirmed and she would fly on July 21 to the pre-Olympic training camp in the UK.

In the Olympic all-around finals, Dmitriyeva took the highest in ribbon with 29.100 and scored a total of 114.500 points to win the silver medal behind compatriot Evgenia Kanaeva.

[9] On 26 February 2013, at a press conference led by Russian head coach Irina Viner, it was suggested that Dmitriyeva might retire from competition due to a recurring leg injury from severe stress,[10] however her personal coach, Olga Buyanova, said she was only pausing her career in order to heal.

Not forgetting that her departure in the sport is associated with quite a serious injury, in the world of gymnastics time plays the most important role and the mode of intensive training and competitions can often have a very serious impact on the career of an athlete".
