Slalom Skateboarding
Slalom skateboarding is a form of wikt:downhill, downhill skateboard racing that first appeared in the 1960s and 1970s and has made a resurgence in popularity in the 2000s. wikt:Slalom, Slalom racers skate down a course usually marked by plastic cones. The racer tries to get through the course with the fastest time, while knocking down the fewest cones. Each cone typically carries a penalty of a fraction of a second (most often 0.1 seconds) which is added to the skater's time. Disciplines Races can be done in dual format where the racing is a head-to-head match, or in a single lane format where the racer is only racing against the clock. There are five types of Slalom race formats: Super Giant Slalom, Giant Slalom, Hybrid Slalom (a.k.a. Special Slalom), Tight Slalom, and Banked Slalom. The Super Giant Slalom, or SuperG, is characterized by fast speeds of 30-40 mph, very long distances between cones (up to 40–50 feet) and run times of around 1 minute. Giant Slalom is similar t ...

Jason At Bear
Jason ( ; ) was an ancient Greece, ancient Greek Greek mythology, mythological hero and leader of the Argonauts, whose quest for the Golden Fleece featured in Greek literature. He was the son of Aeson, the rightful king of Iolcos. He was married to the sorceress Medea. He was also the great-grandson of the messenger god Hermes, through his mother's side. Jason appeared in various literary works in the classical world of Ancient Greece, Greece and Ancient Rome, Rome, including the epic poem ''Argonautica'' and the tragedy ''Medea (play), Medea''. In the modern world, Jason has emerged as a character in various adaptations of his myths, such as the 1963 film ''Jason and the Argonauts (1963 film), Jason and the Argonauts'' and the 2000 TV miniseries of the Jason and the Argonauts (TV miniseries), same name. Persecution by Pelias Pelias (Aeson's half-brother) was power-hungry and sought to gain dominion over all of Ancient Thessaly, Thessaly. Pelias was the progeny of a union ...

Skateboard
A skateboard is a type of sports equipment used for skateboarding. They are usually made of a specially designed 7-8 ply maple plywood deck and polyurethane wheels attached to the underside by a pair of skateboarding trucks. The skateboarder moves by pushing with one foot while the other foot remains balanced on the board, or by pumping one's legs in structures such as a bowl or half pipe. A skateboard can also be used by simply standing on the deck while on a downward slope and allowing gravity to propel the board and rider. If the rider's leading foot is their right foot, they are said to ride "goofy". The two main types of skateboards are the longboard and the shortboard. The shape of the board is also important: the skateboard must be concaved to perform tricks. History Skateboarding started in California in the 1950s. The first skateboards were made from roller skates attached to a board. Skateboarding gained in popularity because of surfing: in fact, skateboarding ...

Racing
In sport, racing is a competition of speed, in which competitors try to complete a given task in the shortest amount of time. Typically this involves traversing some distance, but it can be any other task involving speed to reach a specific goal. A race may be run continuously to finish or may be made up of several segments called heats, stages or legs. A heat is usually run over the same course at different times. A stage is a shorter section of a much longer course or a time trial. Early records of races are evident on pottery from ancient Greece, which depicted running men vying for first place. A chariot race is described in Homer's ''Iliad''. Etymology The word ''race'' comes from a Norse word. This Norse word arrived in France during the invading of Normandy and gave the word ''raz'' which means "swift water" in Brittany, as in a mill race; it can be found in "Pointe du Raz" (the most western point of France, in Brittany), and "''raz-de-marée''" (tsunami).

Skatepark
A skatepark, or skate park, is a purpose-built recreational environment made for skateboarding, BMX, scootering, wheelchairs, and aggressive inline skating. A skatepark may contain half-pipes, handrails, funboxes, vert ramps, stairsets, quarter pipes, ledges, spine transfers, pyramids, banked ramps, full pipes, pools, bowls, snake runs, and any number of other objects. History The first skatepark in the world, Surf City, opened for business at 5140 E. Speedway in Tucson, Arizona on September 3, 1965. Patti McGee, Women's National Champion, attended the grand opening. The park had concrete ramps and was operated by Arizona Surf City Enterprises, Inc. A skatepark for skateboarders and skaters made of plywood ramps on a half-acre lot in Kelso, Washington, USA opened in April 1966. It was lighted for night use. California's first skatepark, the Carlsbad Skatepark opened on March 3, 1976. The World Skateboard Championships were held here on April 10, 1977. It operated un ...

Carbon Fiber
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but other addi ...

Foam
Foams are materials formed by trapping pockets of gas in a liquid or solid. A bath sponge and the head on a glass of beer are examples of foams. In most foams, the volume of gas is large, with thin films of liquid or solid separating the regions of gas. Soap foams are also known as suds. Solid foams can be closed-cell or open-cell. In closed-cell foam, the gas forms discrete pockets, each completely surrounded by the solid material. In open-cell foam, gas pockets connect to each other. A bath sponge is an example of an open-cell foam: water easily flows through the entire structure, displacing the air. A sleeping mat is an example of a closed-cell foam: gas pockets are sealed from each other so the mat cannot soak up water. Foams are examples of dispersed media. In general, gas is present, so it divides into gas bubbles of different sizes (i.e., the material is polydisperse)—separated by liquid regions that may form films, thinner and thinner when the liquid phase drain ...

Skateboarding Styles
A skateboard style refers to the way a skateboarder prefers to ride a skateboard. Skateboard styles can be broadly divided into two different categories: skateboarding to perform tricks and skateboarding as a means of transportation. Styles of skateboarding have evolved over time and are influenced by a number of factors including sociocultural evolution, mass media, music, technology, corporate influence and individual skill level. The styles used by different skateboarders when riding skateboards should not be confused with skater style, the manner in which skateboarders dress or act in relation to skateboarding culture. Styles Freestyle Probably the oldest style of skateboarding, freestyle skateboarding developed from the use of skateboards as a mode of transport in the 1960s. Professional freestyle competitions often involved music and choreography and focused on fluidity and technical skill. The style changed significantly with the introduction of ollies and other trick ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
