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 which results in directional motion. Humans can hold their breath underwater and undertake rudimentary locomotive swimming within weeks of birth, as a survival response.
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.
The butterfly is a swimming stroke swum on the chest, with both arms moving symmetrically, accompanied by the butterfly kick. While other styles like the breaststroke, front crawl, or backstroke can be swum adequately by beginners, the butterfly is a more difficult stroke that requires good technique as well as strong muscles. It is the newest swimming style swum in competition, first swum in 1933 and originating out of the 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 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.
Human swimming typically consists of repeating a specific body motion or swimming stroke to propel that body forward. There are many kinds of strokes, each defining a different swimming style or crawl.
Medley is a combination of four different swimming styles—backstroke, breaststroke, butterfly, and freestyle—into one race. This race is either swum by one swimmer as individual medley (IM) or by four swimmers as a medley relay.
Francesco ("Frank") Pia is an American lifeguard, recognized in the field for his research and training on ways to rescue people in trouble in the water. He is best known for:
The sidestroke is a swimming stroke, so named because the swimmer lies on one's side with asymmetric arm and leg motion and it is helpful as a lifesaving technique and is often used for long-distance swimming. The sidestroke allows the swimmer increased endurance because instead of working both arms and legs simultaneously in the same way, the side stroke uses them simultaneously but differently. A swimmer tired of exercising one side can turn over and use the other, the change of action helping the limbs to recover.
Finning techniques are the skills and methods used by swimmers and underwater divers to propel themselves through the water and to maneuver when wearing swimfins. There are several styles used for propulsion, some of which are more suited to particular swimfin configurations. There are also techniques for positional maneuvering, such as rotation on the spot, which may not involve significant locational change. Use of the most appropriate finning style for the circumstances can increase propulsive efficiency, reduce fatigue, improve precision of maneuvering and control of the diver's position in the water, and thereby increase the task effectiveness of the diver and reduce the impact on the environment. Propulsion through water requires much more work than through air due to higher density and viscosity. Diving equipment which is bulky usually increases drag, and reduction of drag can significantly reduce the effort of finning. This can be done to some extent by streamlining diving equipment, and by swimming along the axis of least drag, which requires correct diver trim. Efficient production of thrust also reduces the effort required, but there are also situations where efficiency must be traded off against practical necessity related to the environment or task in hand, such as the ability to maneuver effectively and resistance to damage of the equipment.
Swimming lessons are the process of learning to swim. In most countries there is a definition of a number of swimming levels that are reached in the process of the curriculum. The respective certificates of swimming tests are required for further training in aquatic abilities. Many countries have defined a minimum swimming level that children should reach by the end of primary education, in most cases with the help of school swimming classes being part of the normal curriculum.
Lifesaving is the act involving rescue, resuscitation and first aid. It often refers to water safety and aquatic rescue; however, it could include ice rescue, flood and river rescue, swimming pool rescue and other emergency medical services. Lifesaving also refers to sport where lifesavers compete based on skills, speed and teamwork. Lifesaving activities specialized in oceanic environment is called surf lifesaving or coastal lifesaving.
Combat side stroke or CSS is a variation of the side stroke that was developed by and taught to the United States Navy SEALs. The Combat Swimmer Stroke was developed for the United States Navy Seals by Former Navy SEAL Stew Smith (CSCS) and Terry Laughlin of Total Immersion Swimming.
The Bronze Medallion, signifying a qualified lifesaver, has been a lifesaving standard award of The Royal Life Saving Society - Australia and Surf Life Saving Australia for over one hundred years. It was developed in England in 1892. It has evolved over the years to accommodate the environmental conditions of Australia.
Swimming is an individual or team racing sport that requires the use of one's entire body to move through water. The sport takes place in pools or open water. Competitive swimming is one of the most popular Olympic sports, with varied distance events in butterfly, backstroke, breaststroke, freestyle, and individual medley. In addition to these individual events, four swimmers can take part in either a freestyle or medley relay. A medley relay consists of four swimmers who will each swim a different stroke, ordered as backstroke, breaststroke, butterfly and freestyle.
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.
The Champaign County YMCA Heat Swim Team (HEAT) is a competitive age group swim program that serves all ages and abilities in Champaign County and the surrounding areas. Participants attend weekly practices in Urbana and Champaign and are offered from 5 different practice levels, determined by their skill. The team is competitive at a national level for the YMCA and USA Swimming/ Illinois Swimming.
Competitive swimming in Britain started around 1830, mostly using breaststroke. Swimming was part of the first modern Olympic games in 1896 in Athens. In 1908, the world swimming association, Fédération Internationale de Natation (FINA), was formed.
The German rescue swimming badge is awarded by the Wasserwacht of the German Red Cross and the DLRG for proficiency in rescue swimming skills. The German rescue swimming badge is awarded in bronze, silver, and in gold. The awards is available as a cloth patch, as a metal badge, or as a ribbon. The rescue swimming badges in silver and gold are permitted to be worn on uniforms of the Bundeswehr, the German Police and various rescue services as a ribbon. It is also an entry-requirement for some German Police agencies.
The German swimming badge is awarded by members of the Wasserwacht of the German Red Cross and the DLRG for completing certain requirements and for demonstrating swimming skills.
The eggbeater kick is a style of kicking where the swimmer's legs alternate one-legged breaststroke kicks. This form provides continuous support because there is no break in the kick, and allows the swimmer to remain stable in the water without swaying. However, it can cause knee problems due to the circular rotation of the knee joint.
