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 ...

List Of Swimming Styles
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. In high school, collegiate, and Olympic swimming, there are two undulating strokes (breaststroke and butterfly stroke) and two alternating strokes (front crawl and backstroke). Most strokes involve rhythmic and coordinated movements of all major body parts — torso, arms, legs, hands, feet, and head. Breathing typically must be synchronized with the strokes, too. It is possible, however, to swim by moving only legs without arms or only arms without legs; such strokes may be used for special purposes, for training or exercise, or by amputees (paralympians) and paralytics. Swimming styles Within a competitive sense particularly, swim stroke techniques are continuously changing to become either easier or more efficient as more people explore the activity. * Front crawl: the faste ...

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 ...

Combat Sidestroke
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 combat side stroke is a relaxing and very efficient swim stroke that is an updated version of the traditional sidestroke. The CSS is a mix of sidestroke, front crawl, and breaststroke. The combat side stroke allows the swimmer to swim more efficiently and reduce the body's profile in the water in order to be less likely to be seen during combat operations if surface swimming is required. The concept of CSS has been that it can be used with or without wearing swim fins (flippers), the only difference being that when wearing swim fins the swimmer's legs will always be kicking in the regular flutter kick The flutter kick is a kicking movement used in both swimming and calisthenics.

Long-distance Swimming
Long-distance swimming is distinguished from ordinary swimming in that the distances involved are longer than are typically swum in pool competitions. When a given swim calls more on endurance than on outright speed, it is the more likely to be considered a long-distance swim. Long-distance swims, however, may take place in pools, such as the 1st official 24 hours World Championship in 1976 won by Peppo Biscarini with a record of 83.7 km (24 hour swims in a 50 m-long pool) or the current 25 meter pool world record of 2008 Olympic gold medalist Maarten van der Weijden. Some of the better-known long-distance swims are crossings of the English Channel, Catalina Channel, Fehmarn Belt and Cook Strait. Ultra-long-distance swimming is sometimes referred to as marathon swimming. The minimum distance that constitutes a marathon swim has dramatically shortened over time. Different organizations adopt various minimum distances. The swimming marathon events at the Olympic games have a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Leg
The human leg, in the general word sense, is the entire lower limb of the human body, including the foot, thigh or sometimes even the hip or gluteal region. However, the definition in human anatomy refers only to the section of the lower limb extending from the knee to the ankle, also known as the crus or, especially in non-technical use, the shank. Legs are used for standing, and all forms of locomotion including recreational such as dancing, and constitute a significant portion of a person's mass. Female legs generally have greater hip anteversion and tibiofemoral angles, but shorter femur and tibial lengths than those in males. Structure In human anatomy, the lower leg is the part of the lower limb that lies between the knee and the ankle. Anatomists restrict the term ''leg'' to this use, rather than to the entire lower limb. The thigh is between the hip and knee and makes up the rest of the lower limb. The term ''lower limb'' or ''lower extremity'' is commonly u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water
Water (chemical formula ) is an Inorganic compound, inorganic, transparent, tasteless, odorless, and Color of water, nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food energy, food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breaststroke
Breaststroke is a human swimming, 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 swimming (sport), competitive swimming. The fastest breaststrokers can swim about 1.70 meters (~5.6 feet) per second. It is sometimes the harde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
