“For most of us in this room, we would conclude that the birth of our children is a big moment in our lives, probably the biggest,” Coe told the congress.
“But I have to say that being given the opportunity to work with all of you and shape the future of our sport is probably the second biggest and (most) momentous occasion of my life."
Coe takes over from Lamine Diack, who said that the sport was in “safe hands” with Coe.
Diack said the “white-haired generation has done what it can, now it’s over to the black-haired generation”.
Ukrainian former pole vault champion Bubka was successful in his bid for reelection as IAAF vice-president.
Qatari Dahlan al-Hamad, Cameroon’s Hamad Kalkaba Malboum and Cuba’s Alberto Juantorena also secured positions as vice-presidents alongside Bubka.
One of Coe’s first jobs as IAAF president is likely to be defending athletics from damning allegations of widespread doping.
The credibility of the IAAF and athletics as a whole has come under attack following reports in the British and German media that a leaked database of tests had revealed “extraordinary” levels of doping.
The IAAF called the allegations “sensationalist and confusing” and also put down claims that it tried to block the publication of a document that showed extensive doping among athletes.
Doping issues are likely to be a feature at the Bird’s Nest stadium for the world championships which kick off on Saturday in Beijing.
