Polunina attempted to sign up with the figure skating section of a local ice sports club in her hometown of
Neryungri in 2002 but a mixup occurred and she was instead placed in the ice hockey section. Though she had no prior experience with ice hockey, she quickly developed an affinity for the sport and soon thereafter joined the girls' ice hockey team of Energiya Neryungrinskaya GRES (}, coached by Alexander Litvintsev, in the nearby town of
Serebryany Bor. In November 2005, she tried out with
Fakel Chelyabinsk of the
Russian Women's Hockey League (RWHL) and was offered a contract but she declined to join the club due to her mother's failing health. Her first professional contract was later signed at age sixteen with
Lokomotiv Krasnoyarsk. The following season, she signed with
HC Tornado (also called Tornado Moscow Region and Tornado Dmitrov) and she remained with the club for the rest of her playing career. With HC Tornado, she was a four-time Russian Champion and four-time champion of the
IIHF European Women's Champions Cup (EWCC). After making her debut with the senior national team in 2008, she and teammate
Alexandra Vafina were invited to play
college ice hockey by universities in the United States. Polunina did not pursue the offers, as she did not feel her English skills were strong enough and she was encouraged to stay in Russia by Litvintsev.
