Badminton Players From Zhejiang
Badminton is a racquet sport played using racquets to hit a shuttlecock across a net. Although it may be played with larger teams, the most common forms of the game are "singles" (with one player per side) and "doubles" (with two players per side). Badminton is often played as a casual outdoor activity in a yard or on a beach; professional games are played on a rectangular indoor court. Points are scored by striking the shuttlecock with the racquet and landing it within the other team's half of the court, within the set boundaries. Each side may only strike the shuttlecock once before it passes over the net. Play ends once the shuttlecock has struck the floor or ground, or if a fault has been called by the umpire, service judge, or (in their absence) the opposing side. The shuttlecock is a feathered or (in informal matches) plastic projectile that flies differently from the balls used in many other sports. In particular, the feathers create much higher drag, causing the shu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olympics 2012 Mixed Doubles Final
The modern Olympic Games (Olympics; ) are the world's preeminent international Olympic sports, sporting events. They feature summer and winter sports competitions in which thousands of athletes from around the world participate in a Multi-sport event, variety of competitions. The Olympic Games, Open (sport), open to both amateur and professional athletes, involves more than 200 teams, each team representing a sovereign state or territory. By default, the Games generally substitute for any world championships during the year in which they take place (however, each class usually maintains its own records). The Olympics are staged every four years. Since 1994 Winter Olympics, 1994, they have alternated between the Summer Olympic Games, Summer and Winter Olympics every two years during the four-year Olympiad. Their creation was inspired by the ancient Olympic Games, held in Olympia, Greece, from the 8th century BC to the 4th century AD. Baron Pierre de Coubertin founded the Int ...

Drag (physics)
In fluid dynamics, drag, sometimes referred to as fluid resistance, is a force acting opposite to the direction of motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers, two solid surfaces, or between a fluid and a solid surface. Drag forces tend to decrease fluid velocity relative to the solid object in the fluid's path. Unlike other resistive forces, drag force depends on velocity. Drag force is proportional to the relative velocity for low-speed flow and is proportional to the velocity squared for high-speed flow. This distinction between low and high-speed flow is measured by the Reynolds number. Drag is instantaneously related to vorticity dynamics through the Josephson-Anderson relation. Examples Examples of drag include: * Net force, Net Aerodynamic force, aerodynamic or Fluid dynamics, hydrodynamic force: Drag acting opposite to the direction of movement of a solid object such as cars, aircraft, and boat hulls. * Viscou ...

Eurasia
Eurasia ( , ) is a continental area on Earth, comprising all of Europe and Asia. According to some geographers, Physical geography, physiographically, Eurasia is a single supercontinent. The concept of Europe and Asia as distinct continents dates back to classical antiquity, antiquity, but their borders have historically been subject to change. For example, the ancient Greeks originally included Africa in Asia but classified Europe as separate land. Eurasia is connected to Africa at the Suez Canal, and the two are sometimes combined to describe the largest contiguous landmass on Earth, Afro-Eurasia. History Eurasia has been the host of many ancient civilizations, including those based in Mesopotamia, Egypt, the Indus Valley and China. In the Axial Age (mid-first millennium BCE), a continuous belt of civilizations stretched through the Eurasian Subtropics, subtropical zone from the Atlantic to the Pacific. This belt became the mainstream of world history for two millennia. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battledore - Youthful Sports
Battledore and shuttlecock, or jeu de volant, is a sport related to the professional sport of badminton. The game is played by two or more people using small racquet, rackets (battledores), made of parchment or rows of catgut, gut stretched across wooden frames, and shuttlecocks, made of a base of some light material, such as cork, with trimmed feathers fixed around the top. The object is for players to bat the shuttlecock from one to the other as many times as possible without allowing it to fall to the ground. The modern game is closely related to the professional sport of badminton. History Games with a shuttlecock are attested to as early as 2,000 years ago, and have been popular in India, China, Japan, and Siam. Various traditional shuttlecock games have been played by North American Indigenous peoples of the Americas, indigenous peoples, including the Kwakiutl, Pima people, Pima, Salish peoples, Salish, and Zuni people, Zuni; they are often played with a feathered shutt ...

Motor Coordination
In physiology, motor coordination is the orchestrated movement of multiple body parts as required to accomplish intended actions, like walking. This coordination is achieved by adjusting kinematic and kinetic parameters associated with each body part involved in the intended movement. The modifications of these parameters typically relies on sensory feedback from one or more sensory modalities (see multisensory integration), such as proprioception and vision. Properties Large degrees of freedom Goal-directed and coordinated movement of body parts is inherently variable because there are many ways of coordinating body parts to achieve the intended movement goal. This is because the degrees of freedom (DOF) is large for most movements due to the many associated neuro- musculoskeletal elements.Bernstein N. (1967). The Coordination and Regulation of Movements. Pergamon Press. New York. Some examples of non-repeatable movements are when pointing or standing up from sitting. Ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strength Athletics
Strength athletics is the collection of strength sports which measure physical strength, based on both: non-standard and historical implements as seen in Strongman and Highland games, and standardized and calibrated equipment as seen in Powerlifting and Olympic weightlifting, Weightlifting. Some of the disciplines have similarities to each other and although it is very difficult to master more than one, some athletes participate in several of them and perform at world class levels. Weightlifting consists of two main lifts (''Snatch (weightlifting), snatch'' and ''clean & jerk'') and powerlifting consists of three main lifts (''Squat (exercise), squat, Bench press, bench'' and ''deadlift'') where all test the maximal strength (one rep max output). Highland games consists of up to about ten different disciplines (including ''stone put, Scottish hammer throw, weight throw, weight over bar, caber toss, Keg-tossing, keg toss'' and ''sheaf toss'') while strongman span across more than th ...

Agility
Agility or nimbleness is an ability to change the body's position quickly and requires the integration of isolated movement skills using a combination of balance, coordination, speed, reflexes, strength, and endurance. More specifically, it is dependent on these six skills: * Balance – The ability to maintain equilibrium when stationary or moving (i.e., not to fall over) through the coordinated actions of our sensory functions (eyes, ears and the proprioceptive organs in our joints); * Static balance – The ability to retain the center of mass above the base of support in a stationary position; * Dynamic balance – The ability to maintain balance with body movement; an equal distribution of weight; * Speed – The ability to move all or part of the body quickly; * Strength – The ability of a muscle or muscle group to overcome a resistance; and lastly, * Coordination – The ability to control the movement of the body in co-operation with the body's sensory functions (e. ...

Aerobic Conditioning
Aerobic conditioning is the use of continuous, rhythmic movement of large muscle groups to strengthen the heart and lungs ( cardiovascular system), as well as changes to the skeletal muscles. Improvement in aerobic conditioning occurs when athletes expose themselves to an increase in oxygen uptake and metabolism, but to keep this level of aerobic conditioning, the athletes must keep or progressively increase their training to increase their aerobic conditioning. Aerobic conditioning is usually achieved through aerobic exercise such as running, swimming, rowing machine, elliptical, treadmill, cycling, etc. A stronger heart does not pump more blood by beating faster but by beating more efficiently, primarily via increased stroke volume and left ventricular mass. Trained endurance athletes can have resting heart rates as low as a reported 28 beats per minute ( Miguel Indurain) or 32 beats per minute ( Lance Armstrong), both of whom were professional cyclists at the highest lev ...

Asia
Asia ( , ) is the largest continent in the world by both land area and population. It covers an area of more than 44 million square kilometres, about 30% of Earth's total land area and 8% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilisations. Its 4.7 billion people constitute roughly 60% of the world's population. Asia shares the landmass of Eurasia with Europe, and of Afro-Eurasia with both Europe and Africa. In general terms, it is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a social constructionism, historical and cultural construct, as there is no clear physical and geographical separation between them. A commonly accepted division places Asia to the east of the Suez Canal separating it from Africa; and to the east of the Turkish straits, the Ural Mountains an ...
