Throw ball and volley ball Recrea=onal (Level C) beginner. Level B -‐ A level B player is slightly more advanced than a beginner. Level BB -‐ Level BB players have a great understanding of the game and its objec2ves. They’re comfortable on the court and know where to be at all 2mes. Level BB players possess several of the skills needed to be successful in a compe22ve environment. These players oDen play compe22vely and typically have in depth knowledge of offensive and defensive game play. Level A -‐ Level A players are above average compe22ve players. These individuals may possess the skills needed to play professionally. They have in depth knowledge of offensive and defensive game play, and use advanced strategies to be successful. Level A players are typically in excellent physical condi2on and are able to compete at a high level. Level AA/Olympic -‐ Very advanced professional players are considered Level AA, or Olympic skilled. They compete at the highest professional level and oDen represent their country in global compe22on. These very advanced players have in depth knowledge of offensive and defensive game play, use advanced strategies to be successful, and are able to perform at the highest levels for an extended period of 2me. Level AA players are in superior physical condi2on and lead their sport in performance and compe22on.
Basket ball equipment -‐clocks, score sheets, scoreboard(s), alterna2ng possession arrows, and whistle-‐operated stop-‐clock systems. The COURT: A general court is 91.9DX49.2D. In NBA it is 94DX50D. Material: wood flooring. Maple planks. Outdoor courts have cement flooring. The basket is a steel rim 18 inches diameter with an abached net affixed to a backboard that measures 6 feet by 3.5 feet and one basket is at each end of the court. The white outlined box on the backboard is 18 inches high and 2 feet wide. At almost all levels of compe22on, the top of the rim is exactly 10 feet above the court and 4 feet inside the baseline. While varia2on is possible in the dimensions of the court and backboard, it is considered important for the basket to be of the correct height – a rim that is off by just a few inches can have an adverse effect on shoo2ng. The size of the basketball is also regulated. For men, the official ball is 29.5 inches in circumference (size 7, or a "295 ball") and weighs 22 oz. If women are playing, the official basketball size is 28.5 inches in circumference (size 6, or a "285 ball") with a weight of 20 oz. LIGHTING-‐1000wabs
Labadie In the interna2onal team version of kabaddi, two teams of seven members each occupy opposite halves of a field of 10 m × 13 m in case of men and 8 m × 12 m in case of women GROUNDS (Kabaddi Grounds) Grounds shall consist of a semi-‐soD or grassy level land. The boundary shall be drawn into a 75 Ft. semi-‐circle of an oval shape from the mid point for out door fields. Grounds for indoor stadiums could be adjusted accordingly with the prior approval from federa2on. The boundary and mid-‐line shall be dis2nctly drawn in white by Three inch thick lines except the por2on of mid line between the two posts which would be Four inch thick line. A clear space of Thirty (30) feet shall be provided all around the play area no one will be allowed to enter during the play off. In the Centre of mid -‐ line, a Four inch thick line measuring 20 feet from inside at equal distance from both ends of the mid -‐ line shall be demarcated to be called a ‘Pala’ or ‘Gate-‐Line’. Two posts, round in shape of soD or playable material with a radius of Six to Nine inches in white color shall be placed at each end of Pala or Gate-‐Line and these posts will not be a part of Gate-‐Line. Raiders must stand at the side corner at the end of their respec2ve half near the center line and opposite to their opponent team as shown in the diagram. Stoppers must stand on the top front of the field from the center line as shown in the diagram. Abached is a diagram showing measurements of the outdoor ground and posi2ons for both Raiders & Stoppers.
Kabaddi is one of the few games which does not require any equipment whatsoever. All that is required is a good play-‐field, ideally situated. Most of the players, even today prefer to play the game bare-‐foot although rules now permit the wearing of soD canvas shoes. Since the game is played bare-‐foot it is very important to ensure that the play field is soD, pebble free and levelled properly, so as to avoid chances of injuries. The game is such that it involves a good deal of rolling and falling during struggles. This is another reason for having and maintaining the right kind of play field. The players' performance also depends to a considerable extent on the type of the play field. The ground should neither be too hard nor too loose. A hard ground will lead to more injuries and this will bring down the players' performance. If the surface of the play-‐field is too loose, it will check the speed of the raiders aback and the game will become slow. As per the rules of the game, a play field must be soD and properly levelled. The methods of preparing the kabaddi play field differs from place to place depending upon weather condi2ons, type of soil, loca2on etc. The criteria for preparing a good kabaddi ground are: (1) Selec=on of site: The first thing to do is to select a suitable site for loca2ng the play field. The area should not have any obstacles such as boulders, lamp-‐posts, culverts etc. It should also be ensured that it does not form a part of a thoroughfare for pedestrians. Place should be hygienic with no drain or garbage dumps nearby causing unhealthy atmosphere. The loca2on should be in such a place where spectators are able to watch the game which will act as a mo2va2ng factor for the players. Since all these factors influence the player physiologically and psychologically, due considera2on should be given in selec2ng a proper site. [4] (2) Soil: Soil is the main factor to be taken into considera2on for preparing the play field. In India, the type of soil differs from place to place. For example, in North India we have soDer soil compared to South India. In South India the soil is s2cky whereas in Western India the soil is more sandy in texture. On the other hand in Eastern India, especially in West Bengal, the soil is black and soD and rain makes this soil very muddy. The amount of digging of the surface to prepare the ground depends solely upon the texture of the soil. (3) Weather condi=ons Weather condi2ons prevailing in the place where the ground is under prepara2on also plays a major deciding factor. Where the weather is mainly dry such as in Gujarat & Rajasthan, the prepara2on differs from a place where there are frequent rains such as Kerala. In places where moisture is required to be retained, a layer of salt is also put under the top surface. Whereas in places where there are frequent rains and excess moisture, we have to put a thick bobom layer of pieces of bricks and coal to absorb the excess moisture quickly. (4) Direc=on In order to avoid direct glare of the sun, the court should be laid in the North-‐ South direc2on. (5) Method I Layer (BoUom Layer) Dig up the required rectangular area approximately 12 inches deep, or according to the nature of the soil of the place. Take out the dug up material, remove stones and other impuri2es like glass pieces etc. by sieving and if usable, keep it aside for further use. Spread a layer of broken bricks or stone chips of four inches depth. Spread two inches of soil over this layer. Use a medium size roller to make this layer seble well. Watering and rolling should be done con2nuously for three days. Rolling should not be done immediately aDer watering since the soil and other material will s2ck to the roller and will damage the ground. II Layer (Middle) A thin layer of one or two inches salt/charcoal pieces are to be spread according to need considering weather condi2ons and moisture required. In some places, a layer of cowdung in a liquid form is also used instead of salt/charcoal. In Bangalore NIS South Centre, a layer of cinder was used with effec2ve results. [5] III Layer (Top Layer) Prepara2on of the top layer of the surface is more important. This top surface should be neither too hard nor too loose. The surface should be soD but firm and well levelled. The soil of the top layer should be a mixture of the finest quality of smooth sand, sieved earth, and sawdust. The en2re mixture should be like a smooth powder. If silt form of clay is available, like in the western part of India, it will be more useful. In Southern India, the upper layer should be preferably of silt since the soil is rela2vely hard. The top layer should be spread approximately 2 to 4 inches thick. The top surface should be an inch over the normal ground level and slightly higher of mid-‐field sloping towards either side so that rain water does not get accumulated in the play field. ADer spreading the upper layer, thorough watering and rolling is required to be done regularly. It is not advisable to use heavy rollers on the top surface. Maintenance of the Play Field Kabaddi courts require con2nuous maintenance. Watering should be done one hour before prac2ce. A watering can or a hose pipe abached with a garden sprinkler should be used to water the play field. Water should not be poured with buckets since the play field will become muddy. ADer a 15 minute gap, scraper should be used to lightly scrap the surface. Once the prac2se session/ game is over, a wooden plank should be used to level the surface, because the level of the surface many become uneven during the game. ADer levelling with the wooden block, a light roller should be used and watering done. Ne>ng should be done once in a week to remove stones or pebbles, if any, on the surface. In hot weather condi2ons watering can be done even during half-‐2me of play to maintain moisture. Once in 2 days, the upper layer should be renewed.

taekwondo Kyorugi (sparring sport category) • There are two players in a bout which is controlled by a referee. • The players are matched according to age group, belt ranking, gender and weight. Contestants wear different coloured
‘tobok’ or uniforms. Points are scored when a player delivers a successful punch or a kick to designated target areas on the trunks and kicks to the head. There are four judges posi2oned in each corner of the contest area, with a 1m safety zone surrounding. Compulsory protec2ve guards are used on the head, body, arms, hands, groin, legs, feet and mouth.
• The dura2on of the contest is two rounds of two minutes each for lower rank belt divisions and three rounds of two minutes each for higher ranked black belt players. There is a one-‐minute rest period between rounds. • The compe22on area measures 10m x 10m and is covered with an EVA mat 20mm thick. • The marginal line of the compe22on area is called the boundary line. • The compe22on area may be installed on a playorm 50cm−60cm high from the base and the outer part of the boundary line is inclined with a gradient of less than 30 degrees for the safety of the contestants. • The safety zone area is 2m outside the boundary line.
Poomsaie (technical sport category) • In this technical compe22on, each player individually performs a pre-‐determined taekwondo form that comprises taekwondo tehcniques using hand and feet techniques such a punching, blocking and kicking. Each form ranges from 40−60 moves. • The players are matched according to age group, belt ranking and gender. Other categories include individual, pairs, teams and crea2ve poomsaie (with music and without music). • The compe22on floor area is a 12m x 12m EVA mat 20mm thick. There are seven judges, four on one side of the compe22on area and three on the other.
Dimensions of a singles squash court • A squash court is a rectangular box with four ver2cal walls of varying height. These are the front wall,
side walls and back wall. It has a level floor and a clear height above the court area. Following are the dimensions of a standard squash court:
• length of court between playing surfaces is 9.75m • width of court between playing surfaces is 6.4m • diagonal is 11.665m • height above floor to lower edge of front wall line is 4.57m • height above floor to lower edge of back wall line is 2.13m • height above floor to lower edge of service line on front wall is 1.780m • height above floor to upper edge of board is 4.8m • distance to nearest edge of short line from back wall is 4.26m • internal dimensions of service boxes is 1.600m • width of all lines and the board is 5cm • minimum clear height above the floor of the court is 5.640m
Ligh=ng • The court is lit by ar2ficial light. The recommended standard is 500 lux, • minimum standard is 300 lux and the television standard is 1200 lux. • The ligh2ng must be shadow-‐free and free from any stroboscopic effects. • In courts with transparent walls, the level of illumina2on is the same on both sides of the wall.
• Normal construc2on is used for the building of squash courts. Solid walls of precast concrete units or prefabricated panelled 2mber framed construc2on are finished with special white plaster. To improve the view for spectators it is advantageous to use transparent material for the back wall.
• The floor needs to be slightly springy and have good surface grip. It is made of light coloured wood(maple or beech) boards running parallel to the side walls. Appropriate grade tongue-‐and-‐groove boards 25mm thck and with a sealing coat should be used.
• Across the foot of the front wall rus a strip made of 2.5mm thck sheet of metal or metal covered plywood painted white.
SHOOTING
Compe22ve shoo2ng consists of a number of events across the four disciplines of rifle, pistol, running target and shotgun. All events are conducted as individual and team events
Small bore rilfe • There are two types of rifle shoo2ng, 0.177 air rifle and 0.22 rimfire rifle. Air rifle shoo2ng is done over 10m from a free standing posi2on. Rimfire rifle shoo2ng is done at a
target 50m away. Rimfire shoo2ng is done unsupported in the prone, kneeling or standing posi2ons. • In all rifle events, compe2tors earn points with their shots at an appropriate sized 10-‐ring target, and the shooter with the most points at the end of the compe22on wins • 10m air rifle (60 shots) men • 10m air rifle (40 shots) women Fullbore rifle • Fullbore Target Rifle is an outdoor shoo2ng discipline that uses high powered rifles. The most common class of compe22on, TR, is restricted to using 5.56mm NATO and
7.62mm NATO calibre rifles. • In Fullbore Target Rifle, compe2tors earn points with shots in a five-‐ring target, and the shooter with the most points at the end of the compe22on wins. Shooters always fire
from a prone posi2on. • Compe2tors shoot distances at ranges every 100m between 300m and 1000m. Galleries are typically from five to 40 targets wide, depending on the number of compe2tors for
which the range has been designed. Running target • Running target involves shoo2ng at targets with dedicated target air rifles and four scopes from 10m. Maximum rifle weight is 5.5kg. The match consists of 30 shots 'slow runs'
and 30 shots 'fast runs'. Slow runs means the target takes five seconds to pass across a 2m gap. Fast runs means the target passes the same gap in 2.5 seconds. • 10m air rifle (60 shots) men • 10m air rifle (40 shots) women
• Pistol • Pistol shoo2ng comprises a number of types including rapid fire, sports pistol, centre fire, standard pistol, 50m pistol, air pistol and others. For pistol events, targets are at 50m
and 25m for the rapid fire and sport pistol events and 10m for the air pistol. The shooter must stand free, without support, with both feet and/or shoes completely within the firing point. The pistol must be held and fired with one hand only. The wrist must be visibly free of support.
• 10m air pistol (60 shots) men • 10m air pistol (40 shots) women • 25m rapid fire pistol (60 shot) men • 25m pistol (30+30 shot) women • 50m pistol (60 shots) men
• Spor=ng clays • Spor2ng clays is a clay target discipline to simulate the type of shoo2ng one could normally expect in the field while hun2ng. The size of the targets, their speed and angles of
flight are all variable, making spor2ng clays a challenging clay target sport. • Unlike conven2onal clay target shoo2ng, where all targets follow regular and standard trajectories from course to course, no two spor2ng clays grounds are the same and no
two grounds have the same targets. In spor2ng clays, aspects of natural terrain at the ground are u2lised so that compe2tors are shoo2ng amongst trees, rocks, uphill, downhill and overhead.
The different types of targets are: • standard clays • 'midis' or 'minis' which are smaller • the larger but very thin 'babue' targets that turn on their side at the end of their trajectories • hard-‐rimmed 'rabbit' targets that roll along the ground • the smallest of all, the 'super-‐mini' is a high-‐speed midget • Targets are thrown in single and double forma2on, and in combina2ons of different sizes and at infinitely variable speeds, from angles of all points of the
compass around the compe2tor. A single round of spor2ng clays consists of 25 targets.
• Shotgun • Clay target shoo2ng is one of the most popular target shoo2ng sports. The firearm used is a shotgun with spinning saucer-‐shaped clay targets (normally 100mm
in diameter and 20mm thick) that are thrown by machine at variable speeds and trajectories to provide the shooter with a small, moving target. Other clay target disciplines such as skeet and trap have set target trajectories.
• Trap (125 targets) men • Trap (75 targets) women • Double trap (120 targets) men • Skeet (125 targets) men • Skeet (75 targets) women
• The special considera2ons taken are: • Distance to exix2ng or planned building areas and to inhabited houses; planned shoo2ng direc2on; soil condi2ons; supply arrangements and waste disposal facili2es; situa2on
in rela2on to road and rail links and parking spaces. • It is important to assess whether it is possible or necessary to deviate from local guidelines. The control of noise pollu2on is a legal necessity and must be planned from the
beginning. For open ranges, in the par2cular allowance sholud be made for addi2onal noise redu2on measures. These can be built-‐in in separate building phases. Approval and permission procedures are determined by na2onal and local regula2ons.
• The design and size of a shoo2ng range should facilitate the economic construc2on of any necessary future addi2ons and extension
JUDO Dimensions for Judo The compe22on area is a minimum of 14m x 14m and a maximum of 16m x 16m and is covered by tatamis or similarly acceptable green material. The compe22on area is divided into two zones. • The contest area is a minimum of 8m x 8m or a maximum of 10m x 10m. Surrounding the contest area is a 1m wide danger zone. • The safety area outside the danger zone is 3m wide. • The compe22on area must be fixed to a resilient floor or playorm. Where two or more adjoining compe22on areas are used, a common safety area of between 3m and 4m is necessary. • A free zone of 50cm must be maintained around the compe22on area. • A strip of blue and a strip of white adhesive tape, 10cm wide and 50cm long, are fixed on the centre of the contest area 4m apart. This is the star2ng posi2on at which the contestants must start and end the contest. The blue tape is fixed to the referee’s right and the white to his leD. • Clear headroom 3.5 to 7.6m.
Floor mats Sec2onal mats 2*1m are close laid to make up contest/compe22on areas. Internal environment Background hea2ng of only 10-‐12.5 deg C Adequate ven2la2on is important to prevent the atmosphere becoming humid causing excessive perspira2on. A damp mat soon becomes dangerous. Storage One 16X16m compe22on area requires 128 mats , best stored on trollies ready for easy use and to avoid mishandling. Storage is also required for match officials table, scoreboard.2mer and pool sheet no2ce board.
Archery
• Archery is the art of shoo2ng arrows from a bow at a target. Although it is essen2ally an individual pursuit, it is possible to par2cipate as a member of a team. Compe22ons in the sport of archery are classified in the following disciplines:
• Outdoor target archery • Indoor target archery • Field archery • Para-‐archery • Run archery • Clout archery • Flight archery • 3D archery • Outdoor target archery • Target archery is the most popular form of archery prac2sed worldwide. Target archery events are called rounds and these consist of a number of ends
at different distances. • Field of play layout • The field of play is divided into shoo2ng lanes containing one to four target bubs. A line parallel to the shoo2ng like is marked 3m in front of the
shoo2ng line. • A wai2ng line is marked at least 5m behind the shoo2ng line. A media line is marked one meter in front of the wai2ng line. • Barriers for the public are erected to keep spectators safe. These barriers must be: • At least 20m away from the sides of the first and last target set at 90m. • 10m behind the wai2ng line. • At least 50m beyond the 90m target line. • The backstop must be high enough to stop arrows which have just missed the top of the bub at 90m. • Field archery • Field archery requires shoo2ng uphill and downhill. Athletes shoot on marked (known) and unmarked (unknown) distances, from 5 to 60 meters,
depending on the division. Shots are uphill, downhill, with various condi2ons, forcing the athletes to adapt on each shot. • The course should not be posi2oned higher than 1800m above sea level and the maximum difference between the highest and the lowest point in a
course should not be more than 100m. • The field course is arranged so that the shoo2ng posi2ons and the targets can be reached without undue difficulty, hazard or waste of 2me. Field
courses should be as condensed as possible. The walking distance from the central (assembly) area to the furthest target should be no more than one kilometre or 15 minutes normal walking.
• The course must include safe paths for judges, medical personnel and to allow for transporta2on of equipment around the course whilst shoo2ng is in progress.
• Indoor target archery • Indoor target archery is shot at 18 or 25 meters a the same targets as outdoor target archery. The
venue generally has a polished wooden floor or a concrete floor and the range layout similar to outdoor field archery.
• Barriers to keep spectators back are erected at least 10m from the end of the target line and are a minimum of 5m behind the wai2ng line. Spectators are not allowed beyond the target line.

TABLE TENNIS Playing area These are the minimum size dimensions needed for the playing area (this means the area required for one table tennis table), based on the standard of table tennis compe22on being played: Interna=onal Events, World Championships & Olympic Games 14m x 7m (46 feet x 23 feet) Na=onal tournaments 12m x 6m (40 feet x 20 feet) Na=onal league / Representa=ve matches 10m x 5m (33 feet x 16 feet 6 inches) Local league / Local tournaments 9m x 5m (30 feet x 16 feet 6 inches) Recrea=onal play and coaching 8.5m x 4.12m (28 feet x 13 feet 6 inches) Ligh=ng The minimum light intensity over the whole of the playing surface (measured at the table surface height) and the clear height from the floor to the light should be as follows: World Championships & Olympic Games 1,000 lux 5m (16 feet 6 inches) above the floor Other Interna=onal and Na=onal tournaments 750 -‐ 1,000 lux 4m (13 feet) above the floor Na=onal league / Representa=ve matches 500 lux 3m (10 feet) above the floor Local league / Local tournaments 500 lux 3m (10 feet) above the floor Recrea=onal play and coaching 300 lux 3m (10 feet) above the floor
Materials The table is made with a Masonite (a type of hardboard) or similarly manufactured 2mber, layered with a smooth, low-‐fric2on coa2ng. Wooden semi-‐sprung floors provide the best surface, whilst solid concrete and carpeted floors are totally unsuitable. The flooring must also provide a good contrast between the table top surface and the surrounding areas, both for the benefit of the players and the spectators, so it should be non-‐reflec2ve. The floor must also be smooth and level and able to support the weight of the table tennis table and the players. Mul=-‐table venue When using a table tennis room size that can accommodate mul2ple tables, they should be arranged side by side rather than long ways. For example, in a badminton court you can get four tables side by side. This provides enough room for recrea2onal play or coaching. Ideally, leaving a gangway between the playing areas gives access to each court without the need to disturb the other courts.
CYCLING
Length Olympic standard velodromes are minimum 250m in circumference. Other velodromes can range from 133m to 500m, although 250m is the most popular length used in all major events. The length of the track is measured 20cm above the inner edge of the track. For outdoor tracks the minimum 250m in length s2ll applies but there is no maximum. The length of a track is such that a whole number of laps or half laps is a distance of one kilometre. For example: 50m track is four laps = 1km 333.333m track is three laps = 1km 500m track is two laps = 1km The width of the track is 5m−10m, depending on the category of racing. Ligh=ng There must be an even spread over the surface of the track without definite pools of light. Surface light values for an indoor track are 300 lux for training or general ac2vity and 600 lux for racing events. A minimum of 1400 lux is required for elite interna2onal events. Track terminology: Blue band and safety zone A rideable area sky-‐blue in colour known as the ‘blue band’ is located along the inside edge of the track. The width is at least 10 per cent of the width of the track. Immediately inside the blue band there is a marked safety zone. The combined width of the blue bank and safety zone is at least 4m for a 250m track and 2.5m for tracks shorter than 250m. Measuring line A black line in a white background, drawn 20cm from the inside edge of the track, numbered every 10m and marked every 5m. Sprinters line Red line marked 85cm from the inner edge of the track. Stayers line Blue line drawn at one third of the total width of the track or 2.45m (whichever is the greater) from the inner edge of the track. Finish line It is a black perpendicular line 4cm wide at the centre of a white bank 72cm wide, situated towards the end of one of the straights and at least a few metres before the start of the banking. 200 metre line A white line is drawn across the track 200m before the finish line, from which point 2mes will be taken for sprint events. Pursuit lines Two red lines half the width of the track in length, perpendicular to the track and in line with one another, drawn at the midpoint of each straight to mark the finish point for pursuit events.
Materials Velodrome tracks are constructed from a variety of materials, including concrete, cinders, wood, asphalt, and in the early days, grass.
FENCING Field of play The piste or fencing mat is made of a conduc2ve surface such as copper mesh or aluminium plate. It is a strip at least 1.5m wide and 14m long with an extension or runback of 1.5m at either end. It should have an even surface. There is a centre line and two en-‐garde lines 2m either side of the centre. There are warning lines 2m from either end of the strip to let a retrea2ng fencer know that he is nearly out of space.
Materials There are three different types of piste: 1. Rubber conduc2ve piste Made from conduc2ve material with a rubber back; lightweight, approximately 25 kg. 2. Aluminium sec2on piste Made from sec2ons of rolled aluminium which are bolted together; weighs approximately 300 kg. 3. Metallic piste Made from woven metal with no backing; weighs approximately 70 kg. Ligh=ng The lux required for recrea2on and training is 500 and for compe22on is 700.

WEIGHTLIFTING Compe==on placorm The playorm is a 4m square. If the floor surrounding the playorm is the same or similar colour, the top edge of the playorm must have a different coloured line of at least 150mm. A clear 1m area surrounding the playorm is compulsory. This area must be flat and free from any obstacle including discs. Weightliding compe==on area The height of the playorm is between 50mm and 150mm. If the playorm is above ground level, a restraining bar at least the width of the playorm is suitably and safely fixed to the stage, at least 1m in front of the playorm. Where a prescribed playorm is not available the compe22on may be conducted within a 4m square marked clearly on the floor. In this case the athlete is only regarded as leaving the playorm if during the execu2on of the liD the athlete’s feet completely leave the marked area. The centre referee must be seated 4m away (measured from the front of the playorm to the rear of the referee’s table) and in line with its centre. The side referees must be seated on the same line as the centre referee, 3m−4m apart. Materials The platform is made of wood, plastic or any solid material and can be covered with a non-slippery material.

CRICKET
The pitch A turf pitch is 20.12m long and 3.05m wide. A non-‐turf pitch is a minimum length of 17.68m and a minimum of 1.83m wide In the case of a turf pitch, the slope of the pitch should not exceed 1 per cent and follow the slope pabern of the oval. If the oval is centre sloped, the pitch square should also slope from the centre. The amount of fall should therefore not exceed 30mm across a 3.05m strip or 200mm along its length, being as flat as possible at the centre. The pitch square should be about 75mm above the level of the ouyield to allow for surface drainage off the pitch.
ORIENTATION North-‐south
CRICKET FIELD . There are no fixed dimensions for the field but its diameter varies between
137m and 150m. Ideally, the oval should fall in all direc2ons from the centre, but failing this, should have a single phase slope of one per cent in any convenient direc2on. If the oval is on a very well drained soil, no slope is required

Super 8 cricket Super 8 cricket is an introductory modified games program for upper primary school aged children. Each team is allowed six to a maximum of 10 players. Only approved plas2c equipment is used. The stumps are a single plas2c mould with weighted base. The pitch is 14m−16m long and can be any reasonably flat surface. The distance from pitch to boundary should not exceed 30m.
CRICKET
Indoor cricket Indoor cricket is a varia2on of standard cricket. A game is played with two teams, each with a maximum of eight players or, in some rare cases, six . Indoor cricket is played on a rectangular, ar2ficial grass-‐surfaced court. The court is enclosed in 2ghtly tensioned ne>ng, including a 4m high ‘ceiling’. Courts are usually constructed in factory units or purpose-‐built centres.
Playing area/net dimensions The court is rectangular, 28m−30m long, 10.5m−12m wide, and roofed by flat ne>ng at 4m and 4.5m high. The walls are also of flexible ne>ng. The cricket pitch is 20m long and 1.8m wide, covered with ar2ficial turf, with the striker’s end close to one end of the court.
The net The net enclosing an indoor cricket court is very 2ghtly tensioned The court is defined by a cubic frame of high-‐strength steel cable, to which the ne>ng is securely abached. Tensioning of the net is achieved by tensioning of this ‘cube’. The lower four cables of the cube are secured directly into the concrete floor. The four lower corners are tensioned to anchor points set into the concrete. The top four cables are all fastened at the corners to anchor points, located on the ceiling/inner-‐roof. These take the main tension and help form the ‘box’ structure of the cables. These top cables are then further fastened to the ceiling for addi2onal support. The shape of the box thus formed is achieved by adjus2ng the tension mainly in the eight corners, with finer tuning possible by individually adjus2ng the extra abachments along the top edges.
Ligh=ng The min ligh2ng is between 1000 and1500 lux. Generally a system of horizontal, fluorescent luminaires, fibed with reflectors and mounted at right angles to the pitch. The reflectors must screen both batsman and bowler from direct view of this light source.

They are marked at each end by a line 8cm wide and 80cm in length, 40cm of which is drawn on the pitch and 40cm off the pitch. The area in front of the 2mekeeper’s table, 5m to either side of halfway line, is kept clear. Goals The distance (inside measurement) between the posts is 3m and the distance from the lower edge of the crossbar to the ground is 2m. The goal posts and crossbar have the same width and depth of 8cm. Nets made of hemp, jute or nylon are abached to the back of the goalposts and crossbar. The lower part of the net is abached to curved tubing or another means of support. The depth of the goal is at least 80cm at the top and 100cm at ground level. The goals must have a stabilising system that prevents them from overturning. Portable goals may be used provided they are as stable as normal goals.
MATERIALS At interna2onal level futsal is played either on a wooden or a synthe2c floor that is smooth and flat and does not restrict the roll of the ball. At other levels futsal is played on a variety of surfaces including astroturf. Concrete or tarmac should be avoided.
SMALL SIDED GAMES (SSG) SSG is the FFA’s modified game for children 6−12 years old. The aim is to give young girls and boys the maximum opportunity to par2cipate in soccer. This program replaces Rooball, with the implementa2on to be complete by 2012. This is all about ‘kids’ soccer’. Kids play on smaller fields with less players, fewer rules and modified equipment. As a result, they get more touches of the ball, more goals scored, increased ac2vity and a lot more fun. SSG is played on any field or open arena. The new age football program is divided into four age specific groups and games: Under 9−10s (Football 7’s) ─ 7 v 7 games on macro fields about a quarter of the size of an adult field Under 11−12s (Football 9’s) ─ 9 v 9 on maxi fields about half an adult-‐sized field Following are diagrams of the FFA’s suggested layouts for SSG football grounds using a full size adult soccer pitch -‐ 120m long x 90m wide (maximum).

INDOOR HOCKEY Indoor hockey or floorball is a version of hockey that is played indoors on a hard, smooth and flat
surface and is usually played in a sports hall. It is a six-‐a-‐side game.
The main difference between indoor and outdoor hockey is that the ball may only be pushed and not hit. Indoor hockey has sideboards along both sidelines which keeps the ball in play.
The pitch The field of play is rectangular, not less than 36m or more than 44m long and not less than 18m or more
than 22m wide. Recommended run-‐off areas are 5m at the backlines and 4m at the sidelines. The two goals at either end of the fields are 3m wide by 2m high.
Sideboards 100mm high run along both sidelines of the pitch. The sideboards must be made of wood or materials with similar physical proper2es
. The goals posts are 2m high to the underside of the crossbar. The crossbar is 3m long between the inside edge of the goal posts. The nets are abached to the goal posts at 150mm intervals.

ICE HOCKEY In ice hockey, two teams, each comprised of six players, use a s2ck to hit a puck. The object of the game
is to put the puck into the opposi2on’s goal and keep it out of your goal. The aim is to score more goals than the opposi2on.
Dimensions of the ice rink Maximum size ─ 61m long x 30m wide (interna2onal compe22on).
Minimum size ─ 56m long x 26m wide. The rink is surrounded by a wall painted white known as the 'boards'. The boards are a minimum of
1.7m high to a maximum of 1.22m high. All doors giving access to the ice surface must swing away from the ice surface. For interna2onal compe22ons, protec2ve glass and end zone nets are obligatory. The glass is 160cm to
200cm high on the ends and extends 4m from the goal line. Goals Goal nets are located in the centre of the goal lines. Goal posts are 1.22m high and 1.83m wide. The goal
posts and horizontal crossbar are painted red. A white nylon cord net encloses the back of the net to prevent the puck from going through.
Ligh=ng Fluorescent lamps are generally used because of the more light per wab and long life expectancy.
Recommended are lamps 30−80 wabs.
