Hockey

Hockey is an a team sports featuring opposing team of 11 players competing at each other by trying to maneuver the ball or puck into the opponents goal using a long stick curved at its end. Non-familiar individuals may find the hockey’s game play a variation from soccer or football, but knowing more about the sport will unveil unique characteristics of this sport. This sports has two types, the field hockey and ice hockey, with ice hockey mostly popular in the US and Canada.

Parts of the Hockey Field

Hockey has two types: the field hockey and the ice hockey. The classification depends on what type of playing surface the game is played, so it safe to say that it has two different sets of field layout as described by the sections below:

Field Hockey Marking and Parts

Field hockey’s field is also known as pitch.  Historically, the game was played on natural turf (grass) but nowadays is predominantly played on an artificial turf. The transition onto artificial pitches came during the 1970s and was made mandatory for major competitions in 1976.

hockey-field

 

The hockey field is rectangular in shape, with the longer side called the sidelines. The opposing shorter edges are referred to as the back line and the portion of this between the goal posts is known as the goal line. On the shorter sides of the playing field, you can see two arcs there, one with the solid mark and the other as dashed marks. The solid-marked arc defines the shooting circle. On top of these arcs there resides the 25-yard line. The center line divides the pitch into two equal fields. The penalty spot is a dot directly perpendicular with the goal during penalty stroke. From the center of each backline, a point is marked 6 feet (1.8 meters) away and a quarter-circle arc having a radius of 48 feet (14.6 meters) is drawn from here on the inside of the field. The two quarter-circles are joined at the top by a straight line measuring 12 feet (3.7 meters) to form the D-shaped striking circle, also referred to as the striking circle or the “D”. Another set of quarter circles are drawn outside these and 18 feet, 1 inch (5.5 meters) away. These arcs are not solid, but dashed.

Ice Hockey Markings and Parts

A hockey rink is an ice rink specifically designed for the game of ice hockey. It is rectangular with rounded corners and surrounded by a wall approximately 40 inches (1 meter) high called the boards.

ice-hockey

 

There are two thick blue lines that divide the rink into three parts, called zones, or in some documentations, these blue line defines the beginning of the end zones. These two lines are used to judge if a player is offside. If an attacking player crosses the line into the other team’s zone prior to the puck crossing, he/she is said to be offside. The red line is the center line, in which aside from dividing the rink into two equal parts, it also used to determine or judge icing. Near the both ends of the rink you can see thin red line is called the goal lines.

Behind the blue lines, you can see two red circles with a dot in its center and some line marks on its perimeters on on the center. These circles are know as the faceoff circles, wherein most faceoffs are happening. The dot inside these circles are known as the faceoff spots. There are 9 of these: 1 on each faceoff circles, 4 on neutral zones – the zone enclosed by the blue line and the center line, and one on the center circle known as the center faceoff.

Ice hockey is one of the few team sports in which there is a live area of play behind the goal. The goal frame extends behind the goal line, as illustrated. The sides of the frame are rounded outwards that prevents players behind the net from passing the puck to the front of the net right along the goal post. In many cases, players try to take advantage of the shape of the goal by deliberately passing the puck off the bottom of the goal frame. This can cause the puck to change direction in a way that confuses the opposing team.

ice-hockey-goal

 

In front of each goal, there is a goal crease, which is surrounded by thin red lines and filled in with light blue. The crease is a special area of the ice designed to allow the goaltender to perform his or her duties without interference. In most leagues, no attacking player may enter the goal crease with a stick, skate or any body part before the puck. For the purposes of this rule, the crease extends vertically from the painted lines to the top of the goal frame. This rule was eliminated from the National Hockey League (NHL) and other North American professional leagues beginning in the 1999-2000 season.

At the sideline, there is the referee crease. It is an area in front of the scorekeepers bench that no player may enter during a stoppage of play. It has no function during play. If a player enters the referee crease during stoppage of play he/she will be ejected.

  • The field of play is rectangular, 91.40 meters long bounded by side-lines and 55 meters wide bounded by back-lines.
  • Sidelines are 91.40 meters long perimeter lines; backlines are 55.00 metres long perimeter lines; 22.90 metres lines across the field 22.90 metres from each back-line as measured between the furthest edges of each line, wherein areas enclosed by and including the 22.90 metres lines, the relevant part of the side-lines, and the back-line are known as the 23 metres areas

These lines are continued in uninterrupted arcs in both directions to meet the back-lines in the form of quartercircles with centres at the inside front corner of the nearer goal-posts. The 3.66 metres line and the arcs are called the circle lines ; the spaces enclosed by these lines, including the lines themselves, are called the circles.

  • For goals, two vertical goal-posts joined by a horizontal crossbar are placed at the centre of each back-line on the external marks. The goal-posts and cross-bar are white, rectangular in cross section, 50 mm wide and between 50 mm and 75 mm deep. The distance between the inner edges of the goal-posts is 3.66 metres and the distance from the lower edge of the cross-bar to the ground is 2.14 metres. the space outside the field, behind the goal-posts and cross-bar and enclosed by the net, side-boards and backboard is a minimum of 0.90 metres deep at the cross-bar and a minimum of 1.20 metres deep at ground-level.
  • For sideboards and backboards, side-boards are 460 mm high and a minimum of 1.20 metres long, positioned on the ground at right angles to the back-line and are fixed to the back of the goal-posts without increasing their width; while back-boards are 460 mm high and 3.66 metres long, positioned on the ground at right angles to the side-boards and parallel to the back-line, and are fixed to the end of the side-boards.

International Ice Hockey Federation (IIHF)

iihf-logoThe IIHF, founded on May 15, 1908 in Paris, France, is the governing body of international ice hockey and inline hockey. The IIHF features 73 member associations, each of which is the national governing body of the sport in its nation. Besides controlling the international rulebook, processing international player transfers, and dictating officiating guidelines, the IIHF runs numerous development programmes designed to bring hockey to a broader population. The IIHF also presides over ice hockey in the Olympic Games, and over the IIHF World Championships at all levels, men, women, juniors under-20, juniors under-18 and women under-18. Each season, the IIHF in collaboration with its local organising committees, runs around 25 different World Championships in the five different categories.

Although the IIHF governs international competitions, the IIHF has very little influence on hockey in North America, where the rules of modern hockey were developed and where the National Hocket League (NHL) is the most influential hockey organization. The Hockey Canada and USA Hockey federations have their own rulebooks, while non-North American federations usually follow the IIHF rules.
