Field Hockey pitch Tanzania

Why a Synthetic Hockey pitch?

The artificial surfaces of a synthetic hockey pitch give the players far much more handle of the ball. Coupled with elevated ball speed, hockey has turn out to be a much more promptly and far much more fascinating game.

A hockey pitch is the playing surface for the game of field hockey. Historically, the game was played on organic turf (grass) but presently it is predominantly played on an artificial turf. The transition onto artificial pitches came in the course of the 1970s and was made mandatory for crucial competitions in 1976. All the lines, markings and aim specifications are outlined by the International Hockey Federation in “The Recommendations of Hockey”.

All line markings on the pitch variety element of the area which they define. For instance, a ball on the side line is nonetheless in the field of play a ball on the line of the penalty circle is in the penalty circle a foul committed much more than the 23-metre (25-yard) line has occurred in the 23-metre area. A ball need to completely cross a boundary line to be out of play, and a ball need to wholly cross the aim line ahead of a aim is scored.

Due to the original formulation of the suggestions in England, the prevalent dimensions of a hockey pitch have been initially expressed in imperial units. The suggestions are now expressed explicitly in metric dimensions (mainly because 1998), although the use of the imperial terms remains widespread in some nations

Field of play on a hockey pitch

Colored pitches are applied to distinguish the field of play (green or blue) from the run-off (red/blue/yellow/orange/and so forth).

The hockey pitch is rectangular in shape. The longer perimeter edges are identified as the side line, the opposing shorter edges are referred as the back line and the portion of this amongst the aim posts is recognized as the aim line. The side line need to measure 91.40 m and the back line will need to measure 55.00 m. There need to be a minimum run-off of two m at the sidelines and 3 m at the backlines which may be a diverse surface for the final meter. All line markings need to be white and 75 millimeters wide. In just about every corner of the pitch, a corner flag of no far much more than 300 mm square is attached to a post of height 1.20–1.50 m.

Historically, the pitch dimensions have been imperial and have been replaced by metric equivalents in 1998. The initial recorded suggestions represented what London clubs have been using at the time. Surbiton Hockey Club’s minutes from 1876 stated that pitches have been to be “100–150 yards (91–137 m) extended and 50–80 yards (46–73 m) wide”. Recommendations by the Hockey Association of England in 1886 specified “1 hundred yards extended by 55 to 60 yards (50 to 55 m) wide”.34 In 1905, the International Recommendations Board permitted the width of the pitch to be “up to 66 yards (60 m)” but this option was reversed in 1909.5 In 1975, the current width of 60 yards was written into the suggestions.34

On artificial surfaces, the field of play will need to be coloured green, ultramarine blue or signal blue. It is permitted for the run-off portion of the pitch to be an selection colour. The London 2012 Olympics started a new trend for blue hockey pitches, mostly mainly because blue turf assists television viewers to clearly see the ball and markings on the hockey pitch in the course of gameplay. Not all hockey pitches have to be blue, but a yellow ball on blue turf is now the prevalent for skilled field hockey tournaments.

Objective

A hockey aim at the 1960 Summer season season Olympics. The aim is deeper at ground level with side and backboards about the base.

Objectives consist of two upright posts placed equidistant from the center of the backline, joined at the prime by a horizontal crossbar. The inner edges of the posts need to be 3.66 metres apart, and the decreased edge of the crossbar need to be two.14 metres (7 ft) above the ground. The goalposts and crossbar need to be white and rectangular in shape with width 50 millimetres and a depth of 50 to 75 millimeters (.

The aim need to be at least 1.20 m deep at ground level and at least .90 m deep at crossbar level. The aim area need to be delimited at ground level by a aim backboard and two sideboards of height 460 millimetres (18 in). Affixed to these boards, the posts and crossbar is a net to quit the ball.eight

Hockey nets can come in diverse dimensions primarily based on how deep at ground level and at crossbar level the aim is. Typical dimensions for a prevalent field hockey net are about 3.7m (W) x two.1m (H) x 1.2m (D).7

The initial hockey objectives have been “7 feet (two.1 m) tall posts placed six yards (5.5 m) apart” but have been lowered to 4 yards (3.7 m) apart in the 1886 suggestions. In 1987, a rule was introduced so that at penalty corners “the initial hit at aim will need to not cross the aim-line bigger than 18 inches (460 mm)”. This saw the introduction of a sideboard and backboard to the objectives which are now mandatory.34

Circle

A view of the penalty circle (sturdy line), the broken circle 5 m from it, and the penalty spot.

A aim is scored when the ball passes completely much more than the aim line but only if the ball was played by an offensive player in the penalty circle. On leading of that, the circle marks the area a goalkeeper may play the ball with any element of his physique and the area precisely exactly where an infringement by a defender final final results in a penalty corner. The terminology circle (or D) is extensively applied although the area is fundamentally formed by a 3.66-metre (4 yd) straight line, parallel to the aim line, connected to two 14.63-metre (16 yd) quadrant arcs.910

The 1876 suggestions stated that “no objectives shall be permitted if the ball be hit from a distance of far much more than 15 yards (14 m) from the nearest goalpost”. A visible “striking circle” with “radius of 15 yards” was codified in 1886.34 The radius of the circle was elevated to 16 yards (15 m) in 1951 for men’s hockey and 1968 for women’s hockey.5 Any cost-free of charge-hit inside 5 m of the circle has slightly diverse suggestions from other men and women concerning other players’ distance a broken circle 5 m from the penalty circle denotes this spot.ten

A penalty spot is centrally positioned straight in front of the aim and applied for a penalty stroke. The spot is 150 mm in diameter and its centre is six.475 m from the outdoors of the aim line.ten Penalty strokes have been introduced in 1963 for deliberately stopping a distinct goal3 they have been initially taken eight yards (7.3 m) from aim. In 1973, a stroke could also be awarded for a deliberate foul in the circle and the spot was moved to 7 yards (six.4 m) from aim the following year.5

Other markings

Simon Gougnard prepares to take a penalty corner from the ten m mark. The 5 m line above demarcates the closest position a defender may stand.

A half-way line, parallel to the back line, divides the pitch in two. The get began of just about every period of play and resumption of play following a aim starts with all players in the half they are defending. The line was also applied for the obselete offside rule.3

Every single single half of the pitch is then divided after once more by a line, referred to as the 23 metre line or 25 yard line, positioned 22.90 m11 from just about every back line. Historically, this was initial applied to resume play instantly following the ball passed much more than the back line and marked by flags at the side of the pitch. In 1949, deliberate defensive offenses in this area resulted in a penalty corner. From 1961, players on the defensive group who have been not involved at the penalty corner stood behind this line (this was then moved to the half-way line two years later). The line was also applied for the offside rule amongst 1987 till the rule was abolished in 1996.3 Now, there are detailed suggestions with regards to fouls and cost-free of charge-hits in the 23 metre region of the pitch.12 Due to the truth 2015, the 23 metre line has also been applied for the attacking group to resume play when it has gone much more than the back line (this replaced extended corners).13

There are added markings 300 mm extended and perpendicular to the back line that denote distances of ten m and 5 m from just about every aim post. These are relevant at a penalty corner the former is the mark from which the attacking group calls for the penalty corner and the latter is the closest position which a defender may stand. These marks had been 5 and ten yards (4.six and 9.1 m) in earlier versions of the suggestions.3 There is a connected mark 5 m from along the side line (from precisely exactly where extended corners have been formerly taken) and a mark 14.six m along the side line indicating the level of the prime of the penalty circle. There are also 150 mm extended markings precisely exactly where the aim posts are situated.14

Artificial playing surface

“artificial grass permits much less tricky ball handle and this in itself assists to lessen the quantity of infringements of the rules—which suggests substantially much less whistle and fewer stoppages. The game therefore becomes much less tricky to adhere to, as adequately as becoming a much more promptly spectacle and significantly far much more fascinating from a spectator point of view.”

Historically, the game was made on organic grass turf. Nonetheless, in 1976, the International Hockey Federation (FIH) made artificial pitches mandatory at all crucial competitions.17 The 1976 Summer season season Olympics in Montreal was the initial of these nonetheless at this time handful of players had observed or played on synthetic pitches.18 Even although it is nonetheless permissible to play on organic turf all national competitions and international matches need to be played on an artificial surface.19 Elite-level competitions, such as the Olympic Games and Globe Cup, get in touch with for a water-mainly primarily based playing surface. Nonetheless, due to water conservation efforts, this is not observed as a extended-term sustainable option and selection elite surfaces that do not get in touch with for water are becoming researched.20

There are three most essential types of artificial hockey pitch surface:

   • Unfilled or water-mainly primarily based – artificial fibers that are densely packed for stabilization, desires irrigation or watering to remain clear of pitch place on

    • Dressed or sand-dressed – artificial fibers can be substantially much less densely packed and sand supports the fibers for element of the pile depth

    • Filled or sand-filled – artificial fibers can be longer and substantially much less densely packed and sand supports the fibers for 1 hundred% of the pile depth

On water-mainly primarily based pitches, shorter fibers and wetted turf lessen friction and boost the speed at which the game can be played. Nonetheless, these pitches get in touch with for watering ahead of, in the course of and instantly following the game and upkeep charges are substantial.

Sand-dressed pitches expense far much more than sand-filled pitches but are preferable for hockey as there is an absence of sand close to the playing surface. Nonetheless, a multi-purpose surface acceptable for sports such as association football and tennis is regularly important and hockey may not be the predominant sport. There are very a handful of diverse specifications and categorizations for artificial turf such as shock absorption, surface rebound, friction, and strength outlined by the International Hockey Federation.26 Lately, longer-pile third-generation or 3G pitches have turn out to be nicely-identified, specifically for football, but these do not usually meet the FIH’s test criteria they are regularly as nicely inconsistent and slow.27

Criticism

The Globe Hockey magazine reported on the initial hockey tournament played on an artificial pitch in 1975—a trial occasion in Montreal prior to the Olympics—and pointed out the surface had “substantial constructive elements”.1516 Steve Ruskin, of Sports Illustrated, pointed out that “A slow, analytical game gave way to 1 unique of nonstop, correct-hop action.”28 Nonetheless, it has been stated that the option to make artificial surfaces mandatory significantly favored far much more affluent Western nations who could afford these new pitches.29 Prior to the switch to an artificial surface the Indian men’s hockey group have been dominant, winning seven of the eight Olympic gold medals amongst 1928 and 1964.28 In 1996, Indian hockey player Ajit Pal Singh stated that in spite of its size ” can afford only 12 or so Artificial Turf fields”.Sardara Singh, captain of the Indian men’s hockey group, pointed out that “hockey players in India play on astroturf [sic] for the initial time at the age of 19 or 20 and uncover it hard to adapt.”29 Nonetheless, the Pakistan hockey group have performed adequately following the transform of surface in spite of the nation becoming worse off economically and getting fewer artificial pitches.16 When describing the transform of surface, Ruskin pointed out that “for India it was like starting much more than, with all nations even in field hockey
