Isinbayeva’s form raises Olympics questions
Isinbayeva missed out on the podium in Monaco after failing in all three attempts on the starting 4.70-meter mark.
"I was ready to jump, but everything went differently to what was expected,” she told AP. "I'm physically and mentally ready for the Games, of course, but as a human, I'm worried like any other competitor."
Germany's Silke Spiegelburg triumphed in the pole vault event, with the result of 4.82 meters.
A two-time Olympic champion, Isinbayeva is one of Russia’s main medal hopefuls at the Games, which kick off in London on July 27.
The 30-year-old is the current the women's pole vault outdoor (5.06) and indoor (5.01) world record holder.
