Buoyancy aid
Buoyancy aid is the name given to aids that reduce the amount of effort required to swim .
Depending on their intended use, a distinction is made between two types of swimming aids: firstly, swimming aids, which swimmers (including beginners) use to stay afloat or to learn certain swimming techniques, and secondly, swimming aids, which are used by athletes who practice theirs Sports often falling into the water (such as canoeists and water skiers ) allow swimming with less effort.
Swimming aids are to be distinguished from life-saving aids, which must also be suitable in the event of fainting ( life jackets ), and secondly from water toys (such as water balls, air mattresses).
Buoyancy aids for surfers, canoeists ...
According to DIN EN 393, swimming aids have a minimum buoyancy of 50 Newtons , are not faint-proof and not suitable for children under 30 kg. These are used, for example, for dinghy sailing , where a life jacket would be too bulky, or for whitewater paddling (also in connection with a chest strap ). The lifejacket, on the other hand, does not count among the swimming aids, as swimming aids are intended for people who are conscious, while lifejackets are also intended to enable unconscious people to survive in the water.
Swimming aids for swimmers
Swimming aids widely used in German-speaking countries
Among the flotation devices, among other water wings , flippers , swimming boards , pull buoy , swim rings , swimming belts , swimming pillows and called the Swimming Tube , and other devices (mainly from PVC and foam polystyrene ), which by its own buoyancy , the swimming support. In the 1930s, a swim ring or swim ring was known as a rubber cavalier . The term also became known through the hit from 1927 " Amalie goes with a rubber cavalier " by Siegwart Ehrlich .
Inflatable water toys such as rubber animals , air mattresses or beach balls are completely unsuitable as swimming aids and dangerous : such objects slip easily when you try to hold on to them and are quickly swept away by the wind. The susceptibility to wind can also lead to rapid drifting into danger zones (deep water area, current zone); Air-filled swimming rings are to be viewed critically as swimming aids on this point.
Buoyancy aids in the United States
In the United States , spontaneous swimming ("dog paddling"; English paddle swim ) is systematically encouraged in beginners' swimming lessons for three to five year olds in order to then develop the crawl swimming from it. The breaststroke never or only later learn American children. To encourage spontaneous swimming, swimming aids are widely used as teaching aids. Most of the swimming aids commonly used in Germany (such as water wings) are, however, not used in the USA because they hinder arm work and thus both spontaneous swimming and crawling. In the USA, they are replaced by air-filled floats or floats made of foam ( back bubble ), which are attached to the child's back with a belt. The "bubble" not only keeps the child afloat, but at the same time brings them into the stable prone position required for active swimming. Learning beginners use in addition to the "Bubble" another tool such as a swimming noodle ( pool noodle ) or a floating weight ( float bar , swim bar , water barbell ). The latter is a plastic rod with two foam floating bodies at the ends. The swimming noodle or swimming dumbbell is placed under the armpits, provides additional buoyancy and also prevents the face from sinking into the water.
