Trudgen
The trudgen is a swimming stroke sometimes known as the ''racing stroke'', or the ''East Indian stroke''. It is named after the English swimmer John Trudgen (1852–1902) and evolved out of sidestroke. One swims mostly upon one side, making an overhand movement, lifting the arms alternately out of the water. When the left arm is above the head, the legs spread apart for a kick; as the left arm comes down the legs extend and are then brought together with a sharp scissor kick. The right arm is now brought forward over the water, and as it comes down the left arm is extended again. The scissor kick comes every second stroke; it involves spreading the legs, then bringing them together with a sudden "snap" movement. The swimmer's face is underwater most of the time; the only chance to breath Breathing (or ventilation) is the process of moving air into and from the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring i ...

New Oxford American Dictionary
The ''New Oxford American Dictionary'' (''NOAD'') is a single-volume dictionary of American English compiled by American editors at the Oxford University Press. ''NOAD'' is based upon the ''New Oxford Dictionary of English'' (''NODE''), published in the United Kingdom in 1998, although with substantial editing, additional entries, and the inclusion of illustrations. It is based on a corpus linguistics analysis of Oxford's 200 million word database of contemporary American English. ''NOAD'' includes a diacritical respelling scheme to convey pronunciations, as opposed to the Gimson phonemic IPA system that is used in ''NODE''. Editions First edition Published in September 2001, the first edition was edited by Elizabeth J. Jewell and Frank Abate. Second edition Published in May 2005, the second edition was edited by Erin McKean. The edition added nearly 3,000 new words, senses, and phrases. It was in a large format, with 2096 pages, and was 8½" by 11" in size. It included a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dictionary (software)
Dictionary is an Application software, application developed by Apple Inc. as a part of macOS. The application provides definitions and synonyms from various dictionaries, Wikipedia articles and a glossary of Apple-related terms. Dictionary was introduced in Mac OS X Tiger, OS X 10.4 with the ''New Oxford American Dictionary'' and ''Oxford American Writer's Thesaurus'' (as well as the ''Wikipedia'' and ''Apple Dictionary'' sections). Mac OS X Leopard, 10.5 added Japanese dictionaries, Mac OS X Lion, 10.7 added the British ''Oxford Dictionary of English'', and OS X Mountain Lion, 10.8 added French, German, Spanish and Chinese. History OS X's progenitor, OPENSTEP (and NEXTSTEP) provided similar functionality, called Digital Webster, providing dictionary and thesaurus definitions from Webster's Dictionary, Webster's Ninth New Collegiate Dictionary and Webster's Collegiate Thesaurus (termed the "First Digital Edition"). OPENSTEP Services provide lookup from all applications. Dict ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sidestroke
The sidestroke is a swimming stroke, so named because the swimmer lies on one's side with asymmetric arm and leg motion. 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. The hands act like oars, and do not waste any power by oblique action. In ordinary swimming on the right side, the left arm moves gently in the water, almost at rest. Then, when the used arm becomes tired, the swimmer turns on the other side, and the left arm works while the right arm rests. The legs move in opposite directions with legs bent, and straighten as they come together. The kicking motion is exaggerated and slow, opening the legs wide to provide more thrust r ...

Breath
Breathing (or ventilation) is the process of moving air into and from the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen. All aerobic creatures need oxygen for cellular respiration, which extracts energy from the reaction of oxygen with molecules derived from food and produces carbon dioxide as a waste product. Breathing, or "external respiration", brings air into the lungs where gas exchange takes place in the alveoli through diffusion. The body's circulatory system transports these gases to and from the cells, where "cellular respiration" takes place. The breathing of all vertebrates with lungs consists of repetitive cycles of inhalation and exhalation through a highly branched system of tubes or airways which lead from the nose to the alveoli. The number of respiratory cycles per minute is the breathing or respiratory rate, and is one of the four primary vital signs of life. Under normal con ...

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 ar ...
