Dolphin Dive
In Diving (sport)#Non-competitive diving, non-competitive diving, a dolphin dive is a form of rapid entry used by lifeguards to quickly traverse stretches of shallow (waist – chest deep) water. To perform a dolphin dive: * The rescuer runs to a point where the water is roughly-waist deep. * Before forward momentum can be slowed, the rescuer leaps forward in a dive position, arching his body to break the surface and reach down towards the ground. * The rescuer then tucks his feet underneath his chest to where his hands were, and begins the next dive. Dolphin dives are performed in rapid succession until the water is neck-deep, at which point the rescuer transitions into an appropriate human swimming, swimming stroke, such as heads-up front crawl or breaststroke.

Diving (sport)
Diving is the sport of jumping or falling into water from a platform or springboard, usually while performing acrobatics. Diving is an internationally recognized sport that is part of the Olympic Games. In addition, unstructured and non-competitive diving is a recreational pastime. Competitors possess many of the same characteristics as gymnasts and dancers, including strength, flexibility, kinaesthetic judgment and air awareness. Some professional divers were originally gymnasts or dancers as both the sports have similar characteristics to diving. Dmitri Sautin holds the record for most Olympic diving medals won, by winning eight medals in total between 1992 and 2008. History Plunging Although diving has been a popular pastime across the world since ancient times, the first modern diving competitions were held in England in the 1880s. The exact origins of the sport are unclear, though it likely derives from the act of diving at the start of swimming races.Wilson, William ...

Lifeguard
A lifeguard is a rescuer who supervises the safety and rescue of swimmers, surfers, and other water sports participants such as in a swimming pool, water park, beach, spa, river and lake. Lifeguards are trained in swimming and CPR/ AED first aid, certified in water rescue using a variety of aids and equipment depending on requirements of their particular venue. In some areas, lifeguards are part of the emergency services system to incidents and in some communities, lifeguards may function as the primary EMS provider. Responsibilities A lifeguard is responsible for the safety of people in an area of water, and usually a defined area immediately surrounding or adjacent to it, such as a beach next to an ocean or lake. The priority is to ensure no harm comes to users of the area for which they are responsible. Lifeguards often take on this responsibility upon employment, although they can also be volunteers. The conditions resulting in drowning are summarized by the 'drowning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Swimming
Swimming is the self-propulsion of a person through water, or other liquid, usually for recreation, sport, exercise, or survival. Locomotion is achieved through coordinated movement of the limbs and the body to achieve hydrodynamic thrust that results in directional motion. Humans can hold their breath underwater and undertake rudimentary locomotive swimming within weeks of birth, as a survival response. Swimming is consistently among the top public recreational activities, and in some countries, swimming lessons are a compulsory part of the educational curriculum. As a formalized sport, swimming is featured in a range of local, national, and international competitions, including every modern Summer Olympics. Swimming involves repeated motions known as strokes in order to propel the body forward. While the front crawl, also known as freestyle, is widely regarded as the fastest out of four primary strokes, other strokes are practiced for special purposes, such as for training. ...

Front Crawl
The front crawl or forward crawl, also known as the Australian crawl or American crawl, is a swimming stroke usually regarded as the fastest of the four front primary strokes. As such, the front crawl stroke is almost universally used during a freestyle swimming competition, and hence freestyle is used metonymically for the front crawl. It is one of two long axis strokes, the other one being the backstroke. Unlike the backstroke, the butterfly stroke, and the breaststroke, the front crawl is not regulated by the FINA. This style is sometimes referred to as the Australian crawl although this can sometimes refer to a more specific variant of front crawl. Ergonomics The face-down swimming position allows for a good range of motion of the arm in the water, as compared to the ''backstroke'', where the hands cannot be moved easily along the back of the spine. The above-water recovery of the stroke reduces drag, compared to the underwater recovery of ''breaststroke''. The alternating a ...

Breaststroke
Breaststroke is a swimming style in which the swimmer is on their chest and the torso does not rotate. It is the most popular recreational style due to the swimmer's head being out of the water a large portion of the time, and that it can be swum comfortably at slow speeds. In most swimming classes, beginners learn either the breaststroke or the freestyle (front crawl) first. However, at the competitive level, swimming breaststroke at speed requires endurance and strength comparable to other strokes. Some people refer to breaststroke as the "frog" stroke, as the arms and legs move somewhat like a frog swimming in the water. The stroke itself is the slowest of any competitive strokes and is thought to be the oldest of all swimming strokes. Speed and ergonomics Breaststroke is the slowest of the four official styles in competitive swimming. The fastest breaststrokers can swim about 1.70 meters (~5.6 feet) per second. It is sometimes the hardest to teach to rising swimmers aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
