A tennis court is the venue where the sport of tennis is played. It is a firm rectangular surface with a low net stretched across the centre. The same surface can be used to play both doubles and singles matches. A variety of surfaces can be used to create a tennis court, each with its own characteristics which affect the playing style of the game.
A climbing wall is an artificially constructed wall with manufactured grips for the hands and feet. Most walls are located indoors, and climbing on such walls is termed indoor climbing. Some walls are brick or wooden constructions, but on most modern walls, the material most often used is a thick multiplex board with holes drilled into it. Recently, manufactured steel and aluminum have also been used. The wall may have places to attach belay ropes, but may also be used to practice lead climbing or bouldering.
A cricket ball is a hard, solid ball used to play cricket. A cricket ball consists of a cork core wound with string then a leather cover stitched on, and manufacture is regulated by cricket law at first-class level. The trajectory of a cricket ball when bowled, through movement in the air, and off the ground, is influenced by the action of the bowler and the condition of the ball and the pitch, while working on the cricket ball to obtain optimal condition is a key role of the fielding side. The principal method through which the batter scores runs is by hitting the ball, with the bat, into a position where it would be safe to take a run, or by directing the ball through or over the boundary. Cricket balls are harder and heavier than baseballs.
Indoor cricket is a variant of and shares many basic concepts with cricket. The game is most often played between two teams each consisting of six or eight players.
Swing bowling is a technique used for bowling in the sport of cricket. Practitioners are known as swing bowlers. Swing bowling is generally classed as a subtype of fast bowling.
A baseball is a ball used in the sport of the same name. The ball consists of a rubber or cork center wrapped in yarn and covered with white natural horsehide or cowhide, or a synthetic composite leather. A regulation baseball is 9 to 9.25 inches in circumference i.e. 2.86 to 2.94 inches in diameter, with a weight of 5 to 5.25 ounces.
Gillnetting is a fishing method that uses gillnets: vertical panels of netting that hang from a line with regularly spaced floaters that hold the line on the surface of the water. The floats are sometimes called "corks" and the line with corks is generally referred to as a "cork line." The line along the bottom of the panels is generally weighted. Traditionally this line has been weighted with lead and may be referred to as "lead line." A gillnet is normally set in a straight line. Gillnets can be characterized by mesh size, as well as colour and type of filament from which they are made. Fish may be caught by gillnets in three ways:
- Wedged – held by the mesh around the body.
- Gilled – held by mesh slipping behind the opercula.
- Tangled – held by teeth, spines, maxillaries, or other protrusions without the body penetrating the mesh.
Glass floats were once used by fishermen in many parts of the world to keep their fishing nets, as well as longlines or droplines, afloat.
Mist nets are used by hunters and poachers, but also by ornithologists and chiropterologists to capture wild birds and bats for banding or other research projects. Mist nets are typically made of nylon or polyester mesh suspended between two poles, resembling a volleyball net. When properly deployed in the correct habitat, the nets are virtually invisible. Mist nets have shelves created by horizontally strung lines that create a loose, baggy pocket. When a bird or bat hits the net, it falls into this pocket, where it becomes tangled.
Filet lace is the general word used for all the different techniques of embroidery on knotted net. It is a hand made needlework created by weaving or embroidery using a long blunt needle and a thread on a ground of knotted net lace or filet work made of square or diagonal meshes of the same sizes or of different sizes. Lacis uses the same technique but is made on a ground of leno or small canvas.
A batting cage is an enclosed area for baseball or softball players to practice the skill of batting.
In cricket a bowling machine is a device which enables a batsman to practise and to hone specific skills through repetition of the ball being bowled at a certain length, line and speed. It can also be used when there is no-one available to bowl, or no one of the desired style or standard.
A driving range is a facility or area where golfers can practice their golf swing. It can also be a recreational activity itself for amateur golfers or when enough time for a full game is not available. Many golf courses have a driving range attached and they are also found as stand-alone facilities, especially in urban areas. They are typically run by businesses or sometimes by universities. Distances are usually marked by target greens at regular distances. Driving ranges may have natural grass, similar to a golf course, or players may use synthetic mats that resemble real turf.
A pitch or a sports ground is an outdoor playing area for various sports. The term pitch is most commonly used in British English, while the comparable term in Australian, American and Canadian English is playing field or sports field.
Net or netting is any textile in which the yarns are fused, looped or knotted at their intersections, resulting in a fabric with open spaces between the yarns. Net has many uses, and comes in different varieties. Depending on the type of yarn or filament that is used to make up the textile, its characteristics can vary from durable to not durable.
A net comprises threads or yarns knotted and twisted into a grid-like structure which blocks the passage of large items, while letting small items and fluids pass. It requires less material than something sheet-like, and provides a degree of transparency, as well as flexibility and lightness.
Queenstown Events Centre, John Davies Oval, or Davies Park is a multi-purpose sports complex and stadium in Queenstown, Otago, in the South Island of New Zealand.
Gillis Field House is a 3,500-seat, multi-purpose arena in West Point, New York. It was home to the United States Military Academy's Army Black Knights men's basketball team until Christl Arena opened in 1985.
Copper alloys are important netting materials in aquaculture. Various other materials including nylon, polyester, polypropylene, polyethylene, plastic-coated welded wire, rubber, patented twine products, and galvanized steel are also used for netting in aquaculture fish enclosures around the world. All of these materials are selected for a variety of reasons, including design feasibility, material strength, cost, and corrosion resistance.
The game of indoor cricket can be played in any suitably sized multi-purpose sports hall. There is evidence of the game being played in the 1920s and 1930s. Furthermore, it was played in the 1960s as a means of giving amateur and professional cricketers a means of playing their sport during the winter months. The first recorded organised indoor cricket league in the world took place in 1970 in North Shropshire, and the first national tournament was completed in 1976 with over 400 clubs taking part. By 1979 over 1000 clubs were taking part in indoor cricket in the UK, and it remains extremely popular today with many leagues around the country. Other forms of indoor cricket have been developed, based on variations of the indoor game.
