Mattia Debertolis was ranked 137th in the world
Italian orienteer Mattia Debertolis has died after collapsing during the World Games in China last week.
The 29-year-old was found unconscious by organisers during an orienteering event last Friday in Chengdu.
The Italian died on Tuesday - four days after his collapse.
"Despite receiving immediate expert medical care at one of China's leading medical institutions, he passed away," World Games organisers said in a statement.
