Pool Dumbbell
A swimming float, commonly known as pool float or floaty, is a device used for toddlers or other very young children who are beginning to learn how to swim, or during exercise for therapeutic or training purposes. These devices, which come in many shapes and types, are used to aid them with buoyancy, or for floating on for fun. The most common floats for children and adults are inflatable rings (in the middle of which the user swims) and inflatable armbands (placed around the user's arms). After being inflated through a valve, they are much less dense than water because they are composed mainly of air, surrounded by a thin layer of synthetic material. Float-assisted swimming can be more difficult than free swimming, because if the float is held in front of the swimmer a more vigorous workout for the legs is given as the swimmer's weight is propelled solely by the legs, and vice versa for the arms.

Girl With Swimming Board
A girl is a young female human, usually a child or an adolescent. When a girl becomes an adult, she is accurately described as a ''woman''. However, the term ''girl'' is also used for other meanings, including ''young woman'',Dictionary.com, "Girl"'' Retrieved January 2, 2008. and is sometimes used as a synonym for ''daughter'', or ''girlfriend''. In certain contexts, the usage of ''girl'' for a woman may be derogatory. ''Girl'' may also be a term of endearment used by an adult, usually a woman, to designate adult female friends. ''Girl'' also appears in portmanteaus (compound words) like ''showgirl'', ''cowgirl'', and '' schoolgirl''. The treatment and status of girls in any society is usually closely related to the status of women in that culture. In cultures where women have a low societal position, girls may be unwanted by their parents, and the state may invest less in services for girls. Girls' upbringing ranges from being relatively the same as that of boys to comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HDPE
High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a thermoplastic polymer produced from the monomer ethylene. It is sometimes called "alkathene" or "polythene" when used for HDPE pipes. With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomembranes and plastic lumber. HDPE is commonly recycled, and has the number "2" as its resin identification code. In 2007, the global HDPE market reached a volume of more than 30 million tons. Properties HDPE is known for its high strength-to-density ratio. The density of HDPE ranges from 930 to 970 kg/m3. The standard method to test plastic density is ISO 1183 part 2 (gradient columns), alternatively ISO 1183 part 1MVS2PRO density analyzer. Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than ...

Swim Ring
A swim ring (also known as a swimming ring, swim tube, rubber ring, water donut, floatie, inner tube, or, in the United States, a lifesaver) is a toroid-shaped (hence the name "ring" or "doughnut") inflatable water toy. The swim ring was derived from the inner tube, the inner, enclosed, inflatable part of older vehicle tires. The inner tube, when inflated, was used as a water toy, and as a floating object to lounge on. The swim ring is not designed to save individuals from drowning. Structure A swim ring consists of two identically-sized layers of flat plastic, one of which contains a valve. The shape of each layer is like a large circle with a smaller, concentric circle removed. The two layers are joined at their inner and outer edges, sealing an air chamber inside. Swim rings (also called "swimming rings", "swimrings", "inner tubes", "innertubes", "rubber rings" or "floaty/floaties") are inflated with air and worn around the user's torso, usually just under the arms or sat u ...

Personal Flotation Device
A personal flotation device (PFD; also referred to as a life jacket, life preserver, life belt, Mae West, life vest, life saver, cork jacket, buoyancy aid or flotation suit) is a flotation device in the form of a vest or suite that is worn by a user to prevent the wearer from drowning in a body of water. The device will keep the wearer afloat with their head and mouth above the surface – they do not have to swim or tread water in order to stay afloat and can even be unconscious. PFDs are commonly worn on small watercraft or other locations where accidental entry into deep water may occur in order to provide immediate support for the wearer should they end up in the water. PFDs are also kept on large vessels for passengers to wear in an emergency in order to help them stay afloat should they be forced to enter the water or accidentally fall overboard during an evacuation. PFD's are commonly worn for swimming and/or other activities that require an individual to be in the water ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lifebuoy
A lifebuoy is a life-saving buoy designed to be thrown to a person in water, to provide buoyancy and prevent drowning. Some modern lifebuoys are fitted with one or more seawater-activated lights, to aid rescue at night. Other names Other names for "lifebuoy" include safety wheel, lifebelt, water wheely, ring buoy, lifering, lifesaver, life donut, life preserver, Perry buoy, or Kisbee ring. The "Kisbee ring", sometimes "kisby ring" or "kisbie ring", is thought to be named after inventor Thomas Kisbee (1792–1877), a British naval officer. Description The lifebuoy is usually ring- or horseshoe-shaped personal flotation device with a connecting line allowing the casualty to be pulled to the rescuer in a boat. They are carried by ships and are also located beside bodies of water that have the depth or potential to drown someone. They are often subjected to vandalism which, since the unavailability of lifebuoys could lead to death, may be punished by fines (up to £5,000 in t ...

Inflatable Armbands
Inflatable armbands, usually referred to as simply armbands, water wings, swimmies, or floaties, are swim aids designed to help a wearer float in water and learn to human swimming, swim. Inflatable Armband, armbands are typically cylinder (geometry), cylindrical, inflatable plastic bands that are inflated and worn on the upper arms. When the wearer is in water, the air inside the armbands provides buoyancy, helping the wearer float. Although often thought of as a swimming aid for children, armbands are also available in adult sizes. Advantages Inflatable armbands are inexpensive, easy to find, and durable. They can help children to build confidence and learn to swim earlier. The amount of flotation provided can be decreased by deflating them partially. During swimming lessons, children may do better in difficult lessons and be easier to supervise if they wear armbands. Criticism Despite their popularity, swimming experts advise against using inflatable armbands. Although they c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Mattress
An air mattress is an inflatable mattress or sleeping pad. Due to its buoyancy, it is also often used as a water toy or flotation device, and in some countries, including the UK, is called a lilo ("Li-lo" being a specific trademark -- derived from the phrase "lie low") or a Readybed. For sleeping An air mattress, also known as an airbed or a blow-up bed, is an inflatable mattress made of polyvinyl chloride (PVC) or textile-reinforced urethane plastic or rubber. The deflated mattress can be compacted and carried or stored in a small form. They are inflated by blowing into a valve, either with a manual or an electric pump. Some are automatically inflated when a valve is opened, up to a certain pressure with additional inflation manually or by pump. Air mattresses are used for camping, temporary or full-time home use, and may be optimized to combine several uses (e.g., camping and guest use) while others are single purpose. Air mattresses may have customized shapes, such as whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dumbbell
The dumbbell, a type of free weight, is a piece of equipment used in weight training. It can be used individually or in pairs, with one in each hand. History The forerunner of the dumbbell, halteres, were used in ancient Greece as lifting weights and also as weights in the ancient Greek version of the long jump. A kind of dumbbell was also used in India for more than a millennium, shaped like a club – so it was named Indian club. The design of the "Nal", as the equipment was referred to, can be seen as a halfway point between a barbell and a dumbbell. It was generally used in pairs, in workouts by wrestlers, bodybuilders, sports players, and others wishing to increase strength and muscle size. Etymology The term "dumbbell" or "dumb bell" originated in late Stuart England. In 1711 the poet Joseph Addison mentioned exercising with a "dumb bell" in an essay published in ''The Spectator''. Although Addison elsewhere in the same publication describes having used equipment sim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pool Noodle
A pool noodle is a cylindrical piece of flexible, buoyant polyethylene foam. Pool noodles are used by people of all ages while swimming. Pool noodles are useful when learning to swim, for floating, for rescue reaching, in various forms of water play, and for aquatic exercise. The most common dimensions are about in length and in diameter. The pool noodle is also used for people who experience difficulties in swimming. The pool noodle is often used to protect sharp edges and corners. Types The term "water woggle" derives from Koswell Holdings trademark Water Woggle, which was first marketed as a foam water toy in the 1980s. The term "noodle" derives from Jakks Pacific's trademark FunNoodle water product, which was created as a foam tube water toy. Canoodle ("connect a noodle") is the polypropylene (plastic) erector set manufactured in the US by Serranoventions. Connectors There are several pool noodle connectors on the market. One connector is a piece of pipe made ou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raft
A raft is any flat structure for support or transportation over water. It is usually of basic design, characterized by the absence of a hull. Rafts are usually kept afloat by using any combination of buoyant materials such as wood, sealed barrels, or inflated air chambers (such as pontoons), and are typically not propelled by an engine. Rafts are an ancient mode of transport; naturally-occurring rafts such as entwined vegetation and pieces of wood have been used to traverse water since the dawn of humanity. Human-made rafts Traditional or primitive rafts were constructed of wood or reeds. Modern rafts may also use pontoons, drums, or extruded polystyrene Polystyrene (PS) is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a ... blocks. Inflatable rafts up to the 20th century used flotation chambers ...

Pull Buoy
A pull buoy or leg float is a figure-eight shaped piece of closed-cell foam used in swim workouts. Swimmers place the buoy between their thighs or their ankles to provide support to the body without kicking their legs; this allows the swimmer to focus on training only their arms and developing both endurance and upper body strength. Using the pull buoy gives the arms a more focused workout by providing flotational support for hips and legs. Good body position and technique can be established and a bilateral breathing rhythm can be refined. The pull buoy can be combined with a rubber ring to tie one's feet together, so there is no notion of kick. It also provides individuals with heavy legs with a way to be better positioned in the water. ''Pull buoy'' is often confused with ''pool buoy'', particularly by those who have never seen the term written. ''Pull'' here refers to the pull phase of the swim stroke Human swimming typically consists of repeating a specific body motion or ...
