- Yelena Isinbayeva got her 2006 season off to a record-breaking start as she broke her world indoor pole vault mark.
The Russian Olympic and world champion rose the bar to 4.91m in her first competition of the season in Donetsk, to better her previous mark of 4.90m.
The Russian also holds the outdoor record of 5.01m set at last year's World Championships in Helsinki.
Isinbayeva will tune up for the defence of her World Indoor title at the Birmingham Grand Prix on 18 February.
The Russian's feat in the Ukraine was the 19th world mark set by the 23-year-old.
