Handball





Playing field
Schematic diagram of a handball playing field (German captions).Handball is played on a court 40 meters long by 20 meters wide (40 m x 20 m), with a goal in the center of each end. The goals are surrounded by a near-semicircular area, called the zone or the crease, defined by a line six meters from the goal. A dashed near-semicircular line nine meters from the goal marks the free-throw line. Each line on the court is part of the area it encompasses. This implies that the middle line belongs to both halves at the same time.
GoalsEach goal has a rectangular clearance area of three meters in the width and two meters in the height. It must be securely bolted either to the floor or the wall behind.
The goal posts and the crossbar must be made out of the same material (e.g. wood or aluminium) and feature a quadratic cross section with a side of 8 cm (3 in). The three sides of the beams visible from the playing field must be painted alternatingly in two contrasting colors which both have to contrast against the background. The colors on both goals must be the same.
Each goal must feature a net. This must be fastened in such a way that a ball thrown into does not leave or pass the goal under normal circumstances. If necessary, a second net may be clasped to the back of the net on the inside.
Goal perimeter
The goals are surrounded by the crease. This area is delimited by two quarter circles with a radius of six meters around the far corners of each goal post and a connecting line parallel to the goal line. Only the defending goalkeeper is allowed inside this perimeter. However, the court players may catch and touch the ball in the air within it as long as the player starts his jump outside the zone and releases the ball before he lands.
If a player contacts the ground inside the goal perimeter he must take the most direct path out of it. However, should a player cross the zone in an attempt to gain an advantage (e.g. better position) his team cedes the ball. Similarly, violation of the zone by a defending player is only penalized if he does so to gain an advantage in defending.
Substitution area
Outside of one long edge of the playing field to both sides of the middle line are the substitution areas for each team. The areas usually contain the benches as seating opportunities. Team officials, substitutes and suspended players must wait within this area. The area always lies to the same side as the team's own goal. During half-time substitution areas are swapped. Any player entering or leaving the play must cross the substitution line which is part of the side line and extends 4.5 meters from the middle line to the team's side
Duration
.A standard match for all teams of 16 and older has two periods of 30 minutes with a 10 minute half-time. Teams may switch sides of the field, as well as benches. For youths the game duration is:
2 x 25 minutes at ages 12 to 16. 2 x 20 minutes at ages 8 to 12. However, national federations of some countries may differ in their implementation from the official guidelines.
If a decision must be reached in a particular match (e.g. in a tournament) and it ends in a draw after regular time, there are at maximum two overtimes of 2 x 5 minutes with a 1 minute break each. Should these not decide the game either, the winning team is determined in a penalty shootout.
The referees may call timeout according to their sole discretion, typical reasons are injuries, suspensions or court cleaning. Penalty throws should only trigger a timeout for lengthy delays as a change of the goalkeeper.
Each team may call one team timeout (TTO) per period which lasts one minute. This right may only be invoked by team in ball possession. To do so, the representative of the team lays a green card marked by black "T" on the desk of the timekeeper. The timekeeper then immediately interrupts the game by sounding an acoustic signal and stops the time.
Ball
A size III handball.The ball is spherical and must either be made of leather or a synthetic material. It is not allowed to have a shiny or slippery surface. As it is intended to be operated by a single hand, the official sizes vary depending on age and gender of the participating teams.
Size Used by Circumference (in cm) Weight (in g) III Men and male youth older than 16 58–60 425–475 II Women, male youth older than 12 and female youth older than 14 54–56 325–375 I Youth older than 8 50–52 290–330.
Resin
product used to improve ball handling.Though not officially regulated, the ball is usually resinated. The resin improves the ability of the players to manipulate the ball with a single hand like spinning trick shots. Some indoor arenas prohibit the usage of resin since many products leave sticky stains on the floor.
Formations
Positions of attacking (red) and defending players (blue), in a 5-1 defense formation. (German captions)Players are typically referred to by the position they are playing. The positions are always denoted from the view of the respective goalkeeper, so that a defender on the right opposes an attacker on the left. However, not all of the following positions may be occupied depending on the formation or potential suspensions.
Offense
Left and right wingman. These typically excel at ball control and wide jumps from the outside of the goal perimeter to get into a better shooting angle at the goal. Teams usually try to occupy the left position with a right-handed player and vice versa. Left and right backcourt. Goal attempts by these players are typically made by jumping high and shooting over the defenders. Thus, it is usually advantageous to have tall players for these positions. Center backcourt. A player with experience is preferred on this position who acts as playmaker and the handball equivalent of a basketball point guard. Pivot (left and right, if applicable). This player tends to intermingle with the defense, setting picks and attempting to disrupt the defense formation. This positions requires the least jumping skills but ball control and physical strength are an advantage.
Defense
Far left and far right. The opponents of the wingmen. Half left and half right. The opponents of the left and right backcourts. Back center (left and right). Opponent of the pivot. Front center. Opponent of the center backcourt, may also be set against another specific backcourt player. Offensive playAttacks are played with all field players on the side of the defenders. Depending on the speed of the attack, one distinguishes between three attack waves with a decreasing chance of success:

First wave
First wave attacks are characterized by the absence of defending players around their goal perimeter. The chance of success is very high the throwing player is unhindered in his scoring attempt. Such attacks typically occur after an intercepted pass or a steal and if the defending team can switch fast to offense. The far left/far right will usually try to run the attack as they are not as tightly bound in the defense. On a turnover, they immediately sprint forward and receive the ball halfway to the other goal. Thus, these positions are commonly held by quick players.[citation needed]
Second wave
If the first wave is not successful and some defending players gained their positions around the zone, the second wave comes into play: The remaining players advance with quick passes to locally outnumber the retreating defenders. If one player manages to step up to the perimeter or catches the ball at this spot he becomes unstoppable by legal defensive means. From this position the chance of success is naturally very high. Second wave attacks became much more important with the "fast throw-off" rule.[citation needed]
Thrid wave
The time during which the second wave may be successful is very short, as then the defenders closed the gaps around the zone. In the third wave, the attackers use standardized attack patterns usually involving crossing and passing between the back court players who either try to pass the ball through a gap to their pivot, take a jumping shot from the backcourt at the goal, or lure the defense away from a wingman.[citation needed] The third wave evolves into the normal offensive play when all defenders reach not only the zone but gain their accustomed positions. Some teams then substitute specialized offense players. However, this implies that these players must play in the defense should the opposing team be able to switch quickly to offense. The latter is another benefit for fast playing teams.[citation needed]

Defensive play
The usual formations of the defense are 6-0, when all the defense players line up between the 6 meter and 9 meter lines to form a wall; the 5-1, when one of the players cruises outside the 9 meter perimeter, usually targeting the center forwards while the other 5 line up on the six meter line; and the lesser common 4-2 when there are two such defenders out front. Very fast teams will also try a 3-3 formation which is close to a switching man-to-man style. The formations vary greatly from country to country and reflect each country's style of play. 6-0 is sometimes known as "flat defense", and all other formations are usually called "offensive defense".[citation needed]
