Rules to play Goal Ball
The defending players stay within the team area, generally in somewhat staggered positions to avoid collisions. When they hear the other team throw the ball, they lay out, that is slide on their hips and stretch their arms above their heads and extend their legs in order to cover as much distance as possible. The objective is simply to keep the ball from getting past with whatever part of the body the player can get in front of it. Some players prefer to block the ball with their chests and absorb the impact. Others like to block with their legs so that the ball will roll up their bodies into their hands. Regardless of method, the players will always try to make themselves as long as possible to block the greatest area.
