[1] Holding a dual citizenship to compete internationally, Moskvina held the 2003 Belarusian senior title in her own division, picked up a total of seventeen medals in her career, including four from the European Championships, and represented her naturalized nation Belarus in two editions of the Olympic Games (1996 and 2004).

Fighting against Algeria's Salima Souakri for a spot in the bronze medal final, Moskvina conceded with a chui penalty and a false attack, and lost the match by points and caution.

[2] At the 2004 Summer Olympics in Athens, Moskvina qualified for her second Belarusian squad, as a 31-year-old veteran and a lone female judoka, in the women's extra-lightweight class (48 kg), by placing second and receiving a berth from the A-Tournament in Tallinn, Estonia.

[2][7] She opened her match with a swift exit from French judoka and eventual silver medalist Frédérique Jossinet, who scored an effortless, fifteen-second ippon victory and pulverized her into the tatami with a sukui nage (scoop throw).

In the repechage, Moskvina gained control to pin Australia's Sonya Chervonsky on the mat within a full minute, before succumbed to a waza-ari awasete ippon hold from China's Gao Feng in her subsequent match.
