Flywire (Nike)
Nike Flywire is a thread, composed of vectran or nylon, developed by Nike to minimize weight and maximize support, and used in the upper part of a sneaker. Shoes containing Flywire became available for consumer purchase in 2008. Development Flywire was created by Jay Meschter, Director of Innovation at Nike. He began by taking a last (an object shaped like a foot used to design shoes) and marking the key points of where a shoe needs to support the foot. When Meschter saw an embroidery machine, he determined the machine could be used to make long stitches. Long stitches allow lightweight fibers to support the foot in key points, instead of using layers of material that support the whole foot. This idea was pioneered by Adi Dassler in 1949, when he added 3 reinforcing stripes to his canvas Adidas running shoe. Design The goal of the design is to help and support the foot using the lightest and strongest material possible, Vectran. The Flywire design (threads placed in key part ...

Nike Air Max
Nike Air Max is a line of shoes produced by Nike, Inc., with the first model released in 1987. Air Max shoes are identified by their midsoles incorporating flexible urethane pouches filled with pressurized gas, visible from the exterior of the shoe and intended to provide cushioning to the underfoot. Air Max was conceptualized by Tinker Hatfield, who initially worked for Nike designing stores. Overview M. Frank Rudy, an aeronautical engineer, first brought the idea of an air-cushioned sole to Nike in 1977. In 1979, he patented a design using polyurethane sacs filled with pressurized inert gas, and Nike has been using some version of this design ever since. As the name indicates, all Air Max shoes feature one or more translucent pouches of pressurized gas embedded in the midsole and visible from the outside of the shoe. Referred to as "Air units" or "airbags," their stated purpose is to provide superior cushioning to traditional foam while also reducing weight. The effectivenes ...

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Basketball
Basketball is a team sport in which two teams, most commonly of five players each, opposing one another on a rectangular Basketball court, court, compete with the primary objective of #Shooting, shooting a basketball (ball), basketball (approximately in diameter) through the defender's hoop (a basket in diameter mounted high to a Backboard (basketball), backboard at each end of the court, while preventing the opposing team from shooting through their own hoop. A Field goal (basketball), field goal is worth two points, unless made from behind the 3 point line, three-point line, when it is worth three. After a foul, timed play stops and the player fouled or designated to shoot a technical foul is given one, two or three one-point free throws. The team with the most points at the end of the game wins, but if regulation play expires with the score tied, an additional period of play (Overtime (sports), overtime) is mandated. Players advance the ball by bouncing it while walking ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Track And Field Athletics
Track and field is a sport that includes Competition#Sports, athletic contests based on running, jumping, and throwing skills. The name is derived from where the sport takes place, a running track and a grass field for the throwing and some of the jumping events. Track and field is categorized under the umbrella sport of athletics, which also includes road running, cross country running and racewalking. The foot racing events, which include sprint (running), sprints, middle-distance running, middle- and long-distance running, long-distance events, racewalking, and hurdling, are won by the athlete who completes it in the least time. The jumping and throwing events are won by those who achieve the greatest distance or height. Regular jumping events include long jump, triple jump, high jump, and pole vault, while the most common throwing events are shot put, javelin throw, javelin, discus throw, discus, and hammer throw, hammer. There are also "combined events" or "multi events", ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Running
Running is a method of terrestrial locomotion allowing humans and other animals to move rapidly on foot. Running is a type of gait characterized by an aerial phase in which all feet are above the ground (though there are exceptions). This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion.Biewener, A. A. 2003. Animal Locomotion. Oxford University Press, US. books.google.com/ref> A feature of a running body from the viewpoint of spring-mass mechanics is that changes in kinetic and potential energy within a stride occur simultaneously, with energy storage accomplished by springy tendons and passive muscle elasticity. The term running can refer to any of a variety of speeds ranging from jogging to Sprint (running), sprinting. Running in humans is associated with improved health and life expectancy. It is assumed that the ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bill Bowerman
William Jay Bowerman (February 19, 1911 – December 24, 1999) was an American track and field coach and co-founder of Nike, Inc. Over his career, he trained 31 Olympic athletes, 51 All-Americans, 12 American record-holders, 22 NCAA champions and 16 sub- 4 minute milers. Bowerman disliked being called a coach, and during his 24 years at the University of Oregon, the Ducks track and field team had a winning season every year but one, attained 4 NCAA titles, and finished in the top 10 in the nation sixteen times. As co-founder of Nike, he invented some of their top brands, including the ''Cortez'' and ''Waffle Racer'', and assisted in the company moving from being a distributor of other shoe brands to one creating their own shoes in house. Early life Born in Portland, Oregon, Bowerman's father Jay was a former governor; his mother, Elizabeth Hoover Bowerman, had grown up in Fossil. The family returned to Fossil after the parents divorced in 1913. Bowerman had an older brothe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Track Spikes
Track spikes, or just spikes, are a type of footwear featuring protruding spikes on the soles used by athletes when racing on the track. Some spikes are designed for longer-term training on tracks, but generally the shoes are used for racing. The term "spikes" can also refer to track shoes featuring such protrusions, though these are technically called pins. Spikes are similar to studs, which are used for team sports, although generally smaller and with a sharp point. History Track spikes had become popular in England by the 1860s, but the concept of spikes in shoes to give running traction has been around much longer. As written in the 1852 publication of ''Calmet's Dictionary of the Holy Bible'' regarding military arms at the time of Paul the Apostle (c. 5 – c. 67): For pioneering the use of spikes, J.W. Foster and Sons's revolutionary running pumps appear in the book, ''Golden Kicks: The Shoes that changed Sport''. The company began distributing shoes across the United ...

Snickers
Snickers is a chocolate bar made by the American company Mars, Incorporated, consisting of nougat topped with caramel and peanuts that is encased in milk chocolate. The annual global sales of Snickers was over $3 billion . In the United Kingdom, Snickers was sold under the brand name Marathon until 1990. A Marathon retro edition was sold exclusively at Morrisons for three months in 2020. History In 1930, Mars introduced Snickers, named after the favorite horse of the Mars family. The Snickers chocolate bar consists of nougat, peanuts, and caramel with a chocolate coating. The bar was marketed under the name "Marathon" in the UK and Ireland until 1990, when Mars decided to align the UK product with the global Snickers name (Mars had marketed and discontinued an unrelated bar named Marathon in the United States during the 1970s which was similar to the UK's Curly Wurly). There are also several other Snickers products such as Snickers mini, dark chocolate, ice cream bars, Sn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gram
The gram (originally gramme; SI unit symbol g) is a Physical unit, unit of mass in the International System of Units (SI) equal to one one thousandth of a kilogram. Originally defined as of 1795 as "the absolute weight of a volume of pure water equal to Cube (algebra), the cube of the hundredth part of a metre [1 Cubic centimetre, cm3], and at Melting point of water, the temperature of Melting point, melting ice", the defining temperature (~0 °C) was later changed to 4 °C, the temperature of maximum density of water. However, by the late 19th century, there was an effort to make the Base unit (measurement), base unit the kilogram and the gram a derived unit. In 1960, the new International System of Units defined a ''gram'' as one one-thousandth of a kilogram (i.e., one gram is Scientific notation, 1×10−3 kg). The kilogram, 2019 redefinition of the SI base units, as of 2019, is defined by the International Bureau of Weights and Measures from the fixed numeric ...

Tendon
A tendon or sinew is a tough, high-tensile-strength band of dense fibrous connective tissue that connects muscle to bone. It is able to transmit the mechanical forces of muscle contraction to the skeletal system without sacrificing its ability to withstand significant amounts of tension. Tendons are similar to ligaments; both are made of collagen. Ligaments connect one bone to another, while tendons connect muscle to bone. Structure Histologically, tendons consist of dense regular connective tissue. The main cellular component of tendons are specialized fibroblasts called tendon cells (tenocytes). Tenocytes synthesize the extracellular matrix of tendons, abundant in densely packed collagen fibers. The collagen fibers are parallel to each other and organized into tendon fascicles. Individual fascicles are bound by the endotendineum, which is a delicate loose connective tissue containing thin collagen fibrils and elastic fibres. Groups of fascicles are bounded by the epitenon, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
