Italian orienteering athlete Mattia Debertolis died on Tuesday at the World Games in Chengdu, China, after collapsing during the competition, organisers said.
Debertolis, 29, was found unconscious during an orienteering event on August 8 and died four days later, said a joint statement from World Games organisers and the International Orienteering Federation (IOF).
The World Games is a multisport event held every four years for disciplines not included in the Olympics.
'Despite receiving immediate expert medical care at one of China's leading medical institutions, he passed away,' the statement said.
It did not provide details on the cause of death.
