Water Polo Cap
A water polo cap is a piece of headgear used in water polo and a number of underwater sports. The caps are used to identify both the player and their team, and to protect their ears from injury possibly caused by a water polo ball hitting the head. Use for water polo Caps are differentiated by the number printed on them as well as the color. Players from the visiting team will wear dark caps, whereas the home team players will wear white caps. The goalkeepers wear quartered red caps, numbered "1", while substitute goalies have caps which are either numbered "1-A" in NCAA games, or "13" in FINA international games. Thus, each team will have two sets of caps: one white and the other dark colored. According to the '' NFHS'' water polo uniform rules, the numbers on the cap contrast the color of the cap, and both the color of the cap and the color of the number contrast the color of the ball.

Water Polo
Water polo is a competitive sport, competitive team sport played in water between two teams of seven players each. The game consists of four quarters in which the teams attempt to score goals by throwing the water polo ball, ball into the opposing team's goal (sport), goal. The team with more goals at the end of the game wins the match. Each team is made up of six field players and one Goalkeeper (water polo), goalkeeper. Excluding the goalkeeper, players participate in both offensive and defensive roles. It is typically played in an all-deep swimming pool, pool where players cannot touch the bottom. A game consists mainly of the players swimming to move about the pool, treading water (mainly using the eggbeater kick), passing the ball, and shooting at the goal. Teamwork, tactical thinking and awareness are also highly important aspects. Water polo is a highly physical and demanding sport and has frequently been cited as one of the most difficult to play.

Referee
A referee is an official, in a variety of sports and competition, responsible for enforcing the rules of the sport, including sportsmanship decisions such as ejection. The official tasked with this job may be known by a variety of other titles depending on the sport, including '' umpire'', ''judge'', '' arbiter'', '' commissaire'', or ''technical official'' (by the International Olympic Committee). Referees may be assisted by '' linesmen'', '' timekeepers'', '' touch judges'', or '' video assistant referees'' (VAR). Football (association) Originally team captains would consult each other in order to resolve any dispute on the pitch. Eventually this role was delegated to an ''umpire''. Each team would bring their own partisan umpire allowing the team captains to concentrate on the game. Later, the referee, a third "neutral" official was added; this ''referee'' would be "referred to" if the umpires could not resolve a dispute. The referee did not take his place on the pi ...

Water is an inorganic compound with the chemical formula . It is a transparent, tasteless, odorless, and Color of water, nearly colorless chemical substance. It is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food energy or organic micronutrients. Its chemical formula, , indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. In liquid form, is also called "water" at standard temperature and pressure. Because Earth's environment is relatively close to water's triple point, water exists on Earth as a solid, a liquid, and a gas. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice ...

Wrestling Headgear
Wrestling headgear is protection that a person wears over the ears and chin during wrestling matches. Description The main purpose of headgear is to protect the ears of the wrestler, not really the head as the name implies. Thus, wrestling headgear equipment are also simply called ear guards or ear protectors. The headgear often covers the ears of the wearer, has two straps that go behind the head, two that go over the front and top part of the head, and one strap that goes under the chin (in some cases the strap will go on the chin). Headgear is often made of durable plastic, velcro, and button snaps. Reason Wrestling headgear is made to protect the wearer from long term injury. The constant bashing and beating on a wrestler's ears that comes from not wearing headgear can cause blood vessels in the ears to burst. These types of injuries do not cause any external bleeding; however incredibly painful sacs of blood will start to develop in the ears often resulting in permanent disf ...

Scrum Cap
The scrum cap is a form of headgear used by Rugby football, rugby players to protect the ears in the scrum (rugby), scrum, which can otherwise suffer injuries leading to the condition commonly known as cauliflower ears. Although originally designed for forwards they are now worn by players of all positions, even those who do not play in the scrum. A simpler alternative to a cap, or a head-cap and used by many players, is a thin strip of foam or cloth and electrical tape wrapped around the ears like a head band. Construction The scrum cap was first used by the Christ's College Finchley's 1st XV, and Eurig Evans is credited with its design. The traditional scrum cap was constructed of a thin cloth helmet with padding over the ears, held in place by a strap—but modern models are typically made from thin foam. The headgear is defined by Regulation 12 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquathlon (underwater Wrestling)
An aquathlon is a multisport race consisting of continuous run and swim elements. Competitors complete a swim immediately followed by a run over various distances. Athletes compete for fastest overall course completion, including the time transitioning between the disciplines. Aquathlon is one of a family of endurance based multisport races, which gained popularity from triathlon and various independent races in the second half of the twentieth century. Modern aquathlon is viewed as a discipline of triathlon as standard races cover the same distances as triathlon but without the cycling leg. As such the sport is governed by International Triathlon Union who organise the world championships each year. History An earliest contested date for aquathlon is hard to state due to it being a combination of swimming and running which both have ancient origins. The modern roots of aquathlon can be traced to life guarding races in Australia, in the 1950s. Races would consist of a run al ...

Swimfin
Swimfins, swim fins, diving fins, or flippers are finlike accessories worn on the feet, legs or hands and made from rubber, plastic, carbon fiber or combinations of these materials, to aid movement through the water in water sports activities such as swimming, bodyboarding, bodysurfing, float-tube fishing, kneeboarding, riverboarding, scuba diving, snorkeling, spearfishing, underwater hockey, underwater rugby and various other types of underwater diving. Swimfins help the wearer to move through water more efficiently, as human feet are too small and inappropriately shaped to provide much thrust, especially when the wearer is carrying equipment that increases hydrodynamic drag. Very long fins and monofins used by freedivers as a means of underwater propulsion do not require high-frequency leg movement. This improves efficiency and helps to minimize oxygen consumption. Short, stiff-bladed fins are effective for short bursts of acceleration and maneuvering, and are useful fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Underwater Rugby
Underwater Rugby (UWR) is an underwater team sport in which two teams compete to deliver a negatively buoyant ball into the opponents’ goal at the bottom of a swimming pool. It originated from physical fitness training programs in German diving clubs during the early 1960s. Recognized by the Confédération Mondiale des Activités Subaquatiques (CMAS) in 1978, it was first played in a world championship in 1980. The sport has little in common with rugby football, except for its name. History In 1961, Ludwig von Bersuda, a member of the German Underwater Club (DUC) in Cologne, conceived the idea of an underwater ball game. Since air-filled balls are unsuitable for underwater games due to buoyancy, von Bersuda experimented with a ball filled with saltwater. Since saltwater is denser than pool water, the ball slowly sinks to the bottom. The sink rate can be controlled within limits by adjusting the concentration of the salt solution. Water polo balls are used instead of l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Underwater Hockey
Underwater hockey (UWH), also known as Octopush in the United Kingdom, is a globally played limited-contact sport in which two teams compete to manoeuvre a puck across the bottom of a swimming pool into the opposing team's goal by propelling it with a hockey stick (or pusher). A key challenge of the game is that players are not able to use breathing devices such as scuba gear whilst playing, they must hold their breath. The game originated in Portsmouth, England in 1954 when Alan Blake, a founder of the newly formed Southsea Sub-Aqua Club, invented the game he called Octopush as a means of keeping the club's members interested and active over the cold winter months when open-water diving lost its appeal. Underwater hockey is now played worldwide, with the Confédération Mondiale des Activités Subaquatiques, abbreviated CMAS, as the world governing body. The first Underwater Hockey World Championship was held in Canada in 1980. History Originally called "Octopush" (and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
