Elise Christie accused her Korean rival Shim Suk-Hee of unsporting behaviour after the Scot missed out on a medal - she finished fourth - in her favoured 1000 metres at the Short Track Speed Skating World Championships in Montreal yesterday, writes Christopher Sweeney.

The Livingston girl was dismayed that the referee did not call a clear push on the Scot, by Shim, the world record holder and eventual winner.

Christie, 23, said: "I got hit and there should have been a call for it, but there wasn't. After she hit me, I couldn't get the speed back up again. To give a hit that early on in a race, it's not really a sportsmanly type thing to do, but she did it and, fair dos, she got a medal today. It worked for her but unfortunately it didn't work for me."

Christie, who had secured a silver behind another Korean, Park Seung-Hi, in the 500m on Saturday, felt the officials at Montreal's Maurice Richard arena were too lenient, in contrast to the Sochi Winter Olympics, where she was disqualified in all three events for infringements. "I got disqualified for less than that; she's pushed me off the track almost; that's why I am finding it harder than normal. I'll talk to her about it when I see her, but there's nothing I can do to change it; I've just got to deal with it."

Christie battled back bravely after the push and only finished three-tenths of a second behind Shim. That followed impressive displays in the qualifying rounds, where she oozed class and cruised through.

Her lack of extra speed in the final may have also been down to her exploits in the 500m on Saturday. She said: "I have never done as much racing in a World Championships as I did over this weekend, so I was quite tired. I guess doing all those 500s might have taken it out of me. I am not used to doing that; I am usually a bit fresher in the 1000m. But it's still been my most successful championships ever and I have got a lot to move forward with."

Christie finished fourth in the overall classification with 36 points, from her fifth in Friday's 1500m and seventh spot in the 3000m. It was all done on two right skates, after both her left blades were broken during the journey to Canada. After the heartache of Sochi and having received death threats on Twitter from irate Chinese fans, she admitted she needs a break from the sport and is looking to take time off.

"I never thought about giving it up," she said. "I have learnt a lot this year and hopefully I'll move forward. I want to take a couple of weeks off but I've not discussed it with my manager yet.

"I need a mental break from skating."
