Also known as 'murderball', the full-contact sport requires equipment that is incredibly durable and can endure constant bombardment, as well as being light, fast and agile.

Wings are positioned in front of the main wheels to make the wheelchair more difficult to stop and hold.
The wheels are covered by spoke protectors to prevent damage during collisions, and all chairs include an anti-tip device at the back.
Wheelchair rugby takes place on Wednesday 5 September in the Basketball Arena at the Olympic Park.
