High school and university students make up the largest group of those interested in working at the event, the International World Games Association (IWGA) said.

Volunteers will play a crucial role in venue preparation, as well as helping members of the media and fans.

They will also be present at Wrocław airport, media and accreditation centres and athletes' accommodation.

It is claimed that organisers will need around 1,500 volunteers for the Games.

From the 2,700 applicants, the Organising Committee will select 1,000 with the remaining 500 chosen by individual sport federations.

In return for their service, volunteers will be provided with meals, uniforms and insurance for the entirety of the Games while those travelling long distances will be given accommodation. 

During the Games, volunteers will also be allowed to use Wrocław’s public transport system for free.

"Such a high level of interest from prospective volunteers only proves again how popular The World Games are in Poland and around the world," said Marcin Przychodny, President of the Wrocław 2017 Organising Committee.

The World Games features sports which are not on the Olympic programme.

Twenty-seven sports will be contested in Wrocław between July 20 and 30 this year.
