ZURICH (AFP) - Russian Yelena Isinbayeva roared back to the top of the women's pole vaulting charts after her disastrous Berlin world championships campaign by setting a new world record of 5.06 metres here on Friday. Isinbayeva, who failed with all three attempts as arch-rival Anna Rogowska of Poland claimed gold at the recently-concluded worlds, bettered her previous best mark of 5.05m set at the Beijing Olympics. "Now I understand why there was that defeat in Berlin - to have this amazing result," said Isinbayeva. "It's like a dream, it's hard to believe. My biggest thanks go to my coach Vitaliy Petrov. He gave me the best advice after what happened in Berlin. "There were also other people who trusted me and said not to worry, everyone can lose a competition. It was interesting that I did not feel any pressure coming into today's competition. "I knew I was in good shape and this world record confirms that I'm here and ready to jump high." Isinbayeva, who still has three competitions to come before season's end, had admitted to being "over-confident" going into the world championships which finished last weekend. The double Olympic champion was a shadow of her usual self in her bid to win a third consecutive world title as she failed at 4.75m and then twice at 4.80m to finish out of the medals. But the 27-year-old looked in top form on Friday, upping the ante against Rogowska and reaching the new world record in just three vaults.
