Russia's Yelena Isinbayeva set another world pole vault record as she took gold at the World Championships on Friday night.

The event's standard bearer had already clinched her first world title when she went clear at 5.01m - a new world best.

The effort came exactly three weeks after Isinbayeva became the first woman to clear 5.00m at the London Grand Prix.

The 23-year-old Russian collected a £58,000 bonus in addition to the £35,000 she won for clinching the gold medal.

Isinbayeva was in a class of her own in Helsinki, with silver medallist Monika Pyrek of Poland managing only 4.60m.

Czech Pavla Hamácková cleared 4.50m to take bronze on countback from Tatyana Polnova and Shuying Gao.
