Sebastian Coe said track and field will continue to experiment with innovation as the sport attempts to win back fans following recent scandal. Speaking as the curtain was set to come down on the World Indoor Championships, the International Association of Athletics Federations (IAAF) president said changes introduced in Portland could feature at next years World Outdoor Championships in London.In the shot put, long jump and triple jump the field was whittled down to the top four athletes for the final attempts in each event, with the changes made in order to ensure that the entire focus of the crowd was on the finale of each event as it took place. Great Britains Robbie Grabarz competes in the high jump final at the IAAF World Indoor Championships in Portland While the innovations appeared to be well-received by spectators, they were not universally embraced by athletes, with New Zealand shot put star Valerie Adams complaining on Saturday about delays in her event. However, Coe said the spirit of change represented the future.Its really important that when we have the opportunity to road test innovation we take it, Coe said.Not everything were going to do is going to work. But Id rather be in a sport where we sometimes have to say Okay, that didnt work quite as planned rather than sitting there sclerotically for the next 10 years. IAAF president Sebastian Coe You arent going to see growth and development of the sport like that if you dont innovate.Some of the things that weve road-tested here youll see in other formats. And youll see evidence of that in London 2017 and beyond.Coe meanwhile insisted that the absence of Russia in Portland - banned from competition after last years World Anti-Doping Agency (WADA) report which uncovered a systemic doping regime in Russian athletics - had not tarnished the meeting. Burundis Francin Niyonsaba (R) and Great Britains Lynsey Sharp compete in the 800m at the IAAF World Indoor Championships in Portland He said: Its a sad moment for our sport ... but it hasnt stopped this from being a fantastic athletic experience for spectators and athletes alike.Coe said the attendances at the Oregon Convention Center - which have been close to sold out over the four days of competition - indicated that the sport retained support despite drugs and corruption scandals.It shows you that the sport is still very strong, Coe added. Nobody is denying the challenges that lie ahead to regain trust but this has been a pretty good start.

But since second-place Curtis Thompson and third-place Riley Dolezal hadnt thrown the Olympic standard of 272 feet 3 inches this year, they are not eligible to go. ' ' '
