Rules to play Goal Ball

1. Goalball
Goalball is a team sport designed specifically for blind athletes, originally devised in 1946 by the Austrian Hanz Lorenzen and German Sepp Reindle as a means of assisting the rehabilitation of visually impaired World War II veterans.Participants compete in teams of three, and try to throw a ball that has bells embedded in it into the opponents goal.Teams alternate throwing or rolling the ball from one end of the playing area to the other, and players remain in the area of their own goal in both defence and attack. Players must use the sound of the bell to judge the position and movement of the ball. Games consist of two 12 minute halves formerly 10 minute halves.Eyeshades allow partially sighted players to compete on an equal footing with blind players.Eyepatches may be worn under eyeshades to ensure complete coverage of the eye, and prevent any vision should the eyeshades become dislodged.

Goalball gradually evolved into a competitive game during the 1950s and 1960s, and was eventually nominated as a demonstration sport at the 1976 Summer Paralympics in Toronto.The sports first world championship was held in Austria in 1978. Goalball was added to the programme of the 1980 Summer Paralympics in Arnhem,becoming the first Paralympic sport designed exclusively for disabled players.International Blind Sports Federation IBSA, responsible for a range of sports for the blind and partially sighted, is the official governing body for the sport.

2. Court and Ball
International Blind Sports Federation rules require the field of play to be 18m long by 9m wide about 19.7 yards by 9.8 yards.Goals span the width of the pitch.The court is divided into six even sections 3 by 9 m. At either end, just in front of the goal, is the team area. Beyond that is each teams landing zone. The middle two sections are collectively referred to as the neutral zone.

The lines of the court are made by placing tape over lengths of twine. This makes the line both visual for officials and tactile for players. The team area and landing zone, including the boundary, goal lines and high ball lines, are always marked in this way. Furthermore, the team area has six hash marks three at the front, one on either side, and one on the goal line to assist with player orientation.

The ball weighs 1.25 kg about 2.76 pounds and has eight holes and noise bells contained within. The balls circumference is around 76 cm about 30 inches.At Paralympic level the ball has been clocked leaving the hand in excess of 60 kph. Despite this, through training and some padding, there are very few injuries.

3. Players
Each team has three players on the court at a time, with 1 3 substitute players on the bench. There are three standard positions to play. Players, while there is typically no official designation, often have a position they are best at or prefer, though some players will play any of the three.

The Center is the player most responsible for defense. He or she typically lines up at the center hash mark at the front of the team area, though there are various defensive arrangements. The center is the most defensive position simply because he or she must be able to move both to the left and right to defend. He or she is also typically the defensive coordinator, as he or she can more accurately determine which opposing player has the ball due to being square to the opposing team.

The Left and Right Wings generally line up at the end of the hash marks coming off of the respective sidelines. Their main defensive responsibilities are keeping the ball out of either corner of the goal, though they also defend some towards the center. Typically, the wings are the main offense, allowing the Center to reserve his or her energy for defense, while they attempt to score. This is not to say that the Center is not also an offensive threat, just that he or she generally is more focused on keeping the ball out of his or her own net than putting it into the opponents.

4. Scoring
A goal is one point and is scored when the ball completely crosses the goal line. The team with the higher score at the end of regulation time is the winner. If regulation results in a tie, two three minute overtime periods are played, for a golden goal first goal concludes the game. If no goal scored during overtime, penalty throws and sudden death penalty throws are taken. Scores can be an intense 10, or 815. When a maximum goal difference of ten is reached, a mercy is called and the leading team is declared the winner.
5. Offense
To score, a player must roll or bounce the ball down the length of the court, past the opposing defenders, and into the opponents goal. Typically, the player with the ball will stand, orient him herself using the tactile lines, sounds from teammates, and or the crossbar of his her own goal. The player will then stride forward, lean low, and roll or sidearm the ball down the court.

The ball must hit in the players own landing zone, and anywhere in the neutral zone. So long as it hits each zone, the style of throw is entirely up to the player in question. Many players will take several strides and release the ball as close to their own highball line as possible; leaning low to ensure a legal throw. Some players will throw after spinning; transferring the momentum of the spin into additional velocity. Others are able to throw the ball so that it will bounce just once in each of the required zones. Most elite players, men and women, are effective when using multiple types of throws.

6. Defence
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.
7. Infractions
Infractions are generally punished by the loss of possession to the other team.
Premature throw throwing the ball before the official has called play.
Pass out while passing between members of the team, the ball crosses the sideline.
Ball over the ball rebounds off a defending player, the crossbar or goalposts and crosses back over half court.
8. Penalties
Penalty situations are for the more competitive players. The rules above outline what justifies a penalty. Basically there are two kinds of Penalties
Team Penalties Ten Seconds Team Delay of Game Team Unsportsmanlike Conduct Illegal Coaching Personal Penalties High Ball Three Throws Eyeshades Personal Unsportsmenlike Conduct Personal Delay of Game Long Ball Illegal Defence
In a penalty situation, only one player will remain on the court, defending the entire goal by himself herself for one penalty shot. This person who stays on is determined by the penalty called. If it is a personal penalty, then it is the one that incurred the penalty that remains on the court. However, if it is a Team Penalty that has been called, then, it is the last person that shot, who remains on the court to defend the goal.
9. Equipment
To play Goalball you will need 1 Goalball, 76cm in diameter, and 1.250g in weight, tactile tape duct tape, and 6 pair of blacked out ski goggles blind folds, which are to be used as eyeshades. You may also want to acquired some knee and elbow pads to protect against bruses and floor burns.
10. The Objective
The object of the game is to simply roll the ball on the floor, in a bowling motion and have the ball completely cross over the opposing teams goal line, scoring a point.
