Isinbayeva changes coach

Paris - Two-time Olympic pole vault champion Yelena Isinbayeva has returned to her first coach Evgeniy Trofimov in a bid to relaunch her career, the the International Association of Athletics Federations (IAAF) said on Monday.

The 28-year-old Russian split with Trofimov after winning the world championships in 2005 with a world record 5.01m to team up with Italian Vitaliy Petrov, coach of Serguei Bubka, who has held the men's world record of 6.15m since 1994.

She pushed her record to 5.06m on August 28, 2009, several days after the first defeat of her career at the world championships in Berlin, but finished off the podium at the world indoor championships in Doha last year.

Since then she has not competed, taking a year off to rest.

Isinbayeva has said she will retire after the world championships in Moscow in 2013.
