WWR has also unveiled a new logo, which features a black background, with the initials "WWR" and "World Wheelchair Rugby" underneath, both in orange.

The change has been accompanied by a 90-second video titled "Here to Win".

It features two-times wheelchair rugby Paralympian Zak Madell, who helped Canada win its first gold medal at the 2015 Parapan American Games in Toronto.

He was also part of the squad that won silver at London 2012.

Madell was chosen for the campaign due to his "fierce competitiveness and determination", according to marketing agency Cossette, who worked on the project.

The video, intended to create excitement during the Games, ends with the message "we're not here to inspire, we're here to win".

"IWRF changes names to World Wheelchair Rugby to celebrate 45 years of sport," said World Wheelchair Rugby President Richard Allcroft.

"By showcasing the game's competitive energy and the determination of the athletes, we're showing a side of the sport that hasn’t really been highlighted this widely before. 

"It sends a strong signal about the future of our sport and challenges people to think differently about disability."

Developed in Canada in 1976, wheelchair rugby was first included on the Paralympic programme at Sydney 2000 and now has more than 30 countries actively competing in the sport.

World Wheelchair Rugby was formed as a section of the International Stoke Mandeville Wheelchair Sports Federation in 1993, better known under its current name, the International Wheelchair and Amputee Sports Federation.

In 2010, it became its own independent governing body as the IWRF, before changing to the WWR name.

Wheelchair rugby is scheduled to end on Sunday (August 29) at the Tokyo 2020 Paralympic Games.
