Antonina Krivoshapka

[4] At the same championships she won a gold medal in the 4 × 400 metres relay with teammates Natalya Antyukh, Darya Safonova and Yelena Voynova.

[6] She went on to win the national title in 49.71 s. With these performances, Krivoshapka was considered one of the favorites for a medal in the 400 m at the World Championships in Berlin.

Krivoshapka suffered an injury in an unusual fashion in early 2010 – while doing sprint training on a track in Volgograd, a young boy walked into her path and she strained her back in the ensuing collision.

She missed the 2010 IAAF World Indoor Championships as a result but fully recovered in time for the outdoor season.

She won a silver medal as part of the Europe 4 × 400 m relay team at the 2010 IAAF Continental Cup.
