Inner Tube Water Polo
Inner tube water polo (ITWP) is a variant of water polo with the important difference that players, excluding the goalkeeper, are required to float in inflatable inner tubes. By floating in an inner tube, players experience less contact and expend less energy than traditional water polo players, not having to tread water. This allows casual players to enjoy water polo without undertaking the intense conditioning required for conventional water polo. This sport is predominantly played at universities, but can also be found in recreational adult leagues.

Water Polo
Water polo is a 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 ball into the opposing team's goal. The team with the most goals at the end of the game wins the match. Each team is made up of six field players and one goalkeeper. Excluding the goalkeeper, players participate in both offensive and defensive roles. It is typically played in an all-deep 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. Special equipment for water polo includes a water polo ball, a ball of varying colors which floats on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goalkeeper (water Polo)
In water polo, the goalkeeper occupies a position as the last line of defense between the opponent's offence and their own team's goal, which is . The goalkeeper position is unique; they possess certain privileges and are subject to different restrictions than those of field players. Accordingly , they possess different skills than those of the field players. Goalkeepers often have longer playing careers than field players because they need mental power rather than physical power. In water polo, the goalkeeper is commonly known as the ''goalie'' or ''keeper'' and may also be known as ''the man/woman in the cage''. Burckett, p. 3 History The position of the goalkeeper has existed since the game of water polo originated. At that time, the object of the game was to touch the ball on the opponent's end of the pool. Wilson, pp. 4–5 The goalkeeper would wait at the end of the pool until an opposing player approached the goal, when the goalkeeper would try to stop that player, f ...

Inner Tube
An inner tube is an inflatable ring that forms the interior of some pneumatic tires. The tube is inflated with a valve stem, and fits inside of the casing of the tire. The inflated inner tube provides structural support and suspension, while the outer tire provides grip and protects the more fragile tube. They are widely used in bicycles and are also used in many motorcycles and heavy road vehicles such as trucks and buses. They are now less common in other wheeled vehicles because of the benefits of having no tube, such as the ability to operate at low pressure and at high pressure (unlike a tube tire, which would pinch at low pressure and burst at high pressure), without going flat. Large inner rings also make effective flotation devices and are widely used in the leisure activity of tubing. Material The tube is made out of a mix of natural and synthetic rubber. Natural rubber is less prone to punctures and is often more pliable, while synthetic rubber is cheaper. Often racin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tread Water
Treading water or water treading is what a swimmer can do while in a vertical position to keep their head above the surface of the water, while not providing sufficient directional thrust to overcome inertia and propel the swimmer in any specific direction. As it expends less energy than traditional strokes, it is often used by swimmers to rest in between periods of exertion without having to leave the water. In figurative language, the expression "treading water" has become a metaphor for an effort expected to create motion, but which actually results in merely staying in one, possibly barely sustainable, place. Methods Any sort of movement that allows the swimmer to do this can be classified as treading water, but it is more efficient to move the arms and legs in a specific fashion. Non-swimmers often splash and kick in an effort to stay above the surface but their lack of technique along with shortness of breath and the panic factor make for a very ineffective method of tread ...

Water Polo Variants
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which 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, H2O, 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°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. 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 may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water covers ab ...

Team Sports
A team sport includes any sport where individuals are organized into opposing teams which compete to win or cooperate to entertain their audience. Team members act together towards a shared objective. This can be done in a number of ways such as outscoring the opposing team. Team members set goals, make decisions, communicate, manage conflict, and solve problems in a supportive, trusting atmosphere in order to accomplish their objectives. Examples are basketball, volleyball, rugby, water polo, handball, lacrosse, cricket, baseball, and the various forms of association football, doubles tennis, and hockey. Team sports require internal coordination between members of the team in order to achieve success. Team sports are practiced between opposing teams, where the players generally interact directly and simultaneously between them to achieve an objective. The objective often involves teammates facilitating the movement of a ball or similar object in accordance with a set of ru ...

Sports Originating In The United States
Sport pertains to any form of competitive physical activity or game that aims to use, maintain, or improve physical ability and skills while providing enjoyment to participants and, in some cases, entertainment to spectators. Sports can, through casual or organized participation, improve participants' physical health. Hundreds of sports exist, from those between single contestants, through to those with hundreds of simultaneous participants, either in teams or competing as individuals. In certain sports such as racing, many contestants may compete, simultaneously or consecutively, with one winner; in others, the contest (a ''match'') is between two sides, each attempting to exceed the other. Some sports allow a "tie" or "draw", in which there is no single winner; others provide tie-breaking methods to ensure one winner and one loser. A number of contests may be arranged in a tournament producing a champion. Many sports leagues make an annual champion by arranging games in a r ...
