Skateboarding

Skateboarding is the act of riding on or performing tricks with a skateboard. A person who skateboards is referred to as a skateboarder or skater.

History
The first skateboard originated sometime in the 1950s and coincided with the initial popularization of surfing in California. The earliest skateboards were homemade and constructed of flat wooden planks attached to roller-skate trucks and wheels. Skateboarding was originally called "sidewalk surfing" and early skaters emulated surfing style and moves. Skateboards may or may not have evolved from "crate scooters." Crate scooters preceded skateboards, and were essentially similar except for having a wooden crate attached to the front, which formed rudimentary handlebars. In the film Back to the Future, Marty McFly is seen confiscating such a scooter from an unsuspecting '50s youth, and ripping the crate off to fashion an improvised skateboard.

In the mid 1960s, skateboarding went mainstream. A number of surfing manufacturers such as Hobie and Makaha started building skateboards that resembled small surfboards and assembling teams to promote their products. The popularity of skateboarding at this time spawned a national magazine, Skateboarder Magazine and the 1965 international championships were broadcast on national television. The growth of skateboarding at this time can also be seen in Makaha's sales figures which quoted $4 million worth of board sales between 1963 and 1965 (Weyland, 2002:28). Yet by 1966 sales had dropped significantly (ibid) and Skateboarder Magazine had stopped publication. Skateboarding's popularity dropped and remained low until the early 1970s.

Second generation
In the early 1970s, Frank Nasworthy started to develop a skateboard wheel made of polyurethane. The improvement in traction and performance was so immense that the popularity of skateboarding started to rise rapidly again, and companies started to invest more in product development. Many companies started to manufacture trucks (axles) especially designed for skateboarding. As the equipment became more maneuverable, the decks started to get wider, reaching widths of 10 inches and over in the end, thus giving the skateboarder even more control. Banana board is a term used to describe skateboards made of polypropylene that were skinny, flexible, with ribs on the underside for structural support and very popular during the mid-1970s. They were available in myriad colors, bright yellow probably being the most memorable, hence the name.

Manufacturers started to experiment with more exotic composites, like fiberglass and aluminum, but the common skateboards were made of maple plywood. The skateboarders took advantage of the improved handling of their skateboards and started inventing new tricks. Skateboarders, most notably the Z-Boys, started to skate the vertical walls of swimming pools that were left empty in the 1976 California drought. This started the vert trend in skateboarding. With increased control, vert skaters could skate faster and perform more dangerous tricks, such as slash grinds and frontside/backside airs. This caused liability concerns and increased insurance costs to skatepark owners. During this era, the "freestyle" movement in skateboarding began, which can be characterized by the development of a wide assortment of flat-ground tricks.

Skateparks increasingly had to contend with high-liability costs that led to many parks closing, Vert skaters therefore started making their own ramps and freestylers didn't need skateparks. Thus by the beginning of the 1980s, skateboarding had died again.

Third generation
The third skateboard generation, from the early/mid eighties to early nineties, was fueled by skateboard companies that were run by skateboarders. The focus was initially on vert ramp skateboarding. The invention of the no-hands aerial (later known as the ollie) by Alan Gelfand in 1976 made it possible for skaters to perform airs off of vertical ramps. While this wave of skateboarding was sparked by commercialized vert ramp skating, a majority of people who skateboarded during this period never rode vert ramps. Because most people couldn't afford to build vert ramps or didn't have access to nearby ramps, street skating gained popularity. Freestyle skating remained healthy throughout this period with pioneers such as Rodney Mullen inventing the basics of modern street skating; the flatground ollie, the ollie kickflip, the heelflip, and the 360 flip, to name a few. The influence freestyle had on street skating became apparent during the mid-eighties, but street skating was still performed on wide vert boards with short noses, slide rails, and large soft wheels. Skateboarding, however, evolved quickly in the late 1980s to accommodate the street skater. Since few skateparks were available to skaters at this time, street skating pushed skaters to seek out shopping centers and public and private property as their "spot" to skate. Public opposition, and the threat of lawsuits, forced businesses and property owners to ban skateboarding on their property. By 1992, only a small fraction of skateboarders remained as a highly technical version of street skating, combined with the decline of vert skating, produced a sport that lacked the mainstream appeal to attract new skaters.

Current generation
The fourth and current generation of skateboards is dominated by street skating. Most boards are about 7¼ to 8 inches wide and 30 to 32 inches long. The wheels are made of an extremely hard polyurethane, durometer (approximately 99a). Additionally, very high durometers offer the benefit of reduced drag on hard surfaces which results in an overall faster ride. The wheel sizes are relatively small so that the boards are lighter, thus making tricks more manageable. Today, modern wheels are currently around 48 to 60 mm in diameter and advances in technology have made them extremely light compared to the wheels of the eighties. Most decks are still constructed out of Canadian Maple, with 7-plys being the industry standard for strength and durability. Board styles have changed dramatically since the 1970s but have remained mostly alike since the mid 1990s. The contemporary shape of the skateboard is derived from the freestyle boards of the 1980s with a largely symmetrical shape and relatively narrow width. During the 90s ramp or vert skateboarding dropped in popularity.

While street skateboarding remains popular, there is a resurgence of other types of skateboarding brewing. Longboarding, pool or bowl skating, slalom and ditch skateboarding are thriving all over the world, albeit below the radar.

Trick skating

Early skate tricks consisted mainly of two-dimensional maneuvers (e.g. riding on only the front wheels (nose manual), spinning like an ice skater on the back wheels (a 360 pivot), high jumping over a bar (sometimes called a "Hippie Jump"), long jumping from one board to another (often over fearless teenagers lying on their backs), and slalom.

In 1976, skateboarding was transformed by the invention of the first modern skateboarding trick by Alan "Ollie" Gelfand. It remained largely a unique Florida trick from 1976 until the summer of 1978, when Gelfand made his first visit to California. Gelfand and his revolutionary manoeuver caught the attention of the West Coast skaters and the media where it began to spread worldwide. An ollie is performed by popping the tail of the skateboard, sliding the front foot towards the nose and lifting up the back foot to level the skateboard out. This results in the skateboarder, along with his or her skateboard, lifting into the air without the aid of foot straps or the skateboarder's hands.

The ollie was reinvented by Rodney Mullen in 1981, who adapted it to freestyle skating by ollieing on flat ground rather than out of a vert ramp. Mullen also invented the ollie kickflip, which, at the time of its invention, was dubbed the "magic flip." The flat ground ollie allowed skateboarders to perform tricks in mid-air without any more equipment than the skateboard itself. The development of these complex tricks by Rodney Mullen and others transformed skateboarding. Skateboarders began performing their tricks down stair sets and on other urban obstacles - they were no longer confined to empty pools and expensive wooden ramps.

The act of "ollieing" onto an obstacle and sliding along it on the trucks of the board is known as grinding, and has become a mainstay of modern skateboarding. Types of grinds include the 50-50 grind (balancing on the front and back trucks while grinding a rail), the 5-0 grind (balancing on only the back truck while grinding a rail) the nose grind (balancing on only the front truck while grinding a rail), and the crooked grind (balancing on the front truck at an angle while grinding). There are various other grinds that involve touching both the trucks and the deck to the rail, ledge, or lip. The most common of these is the smith grind, in which the rider balances over the back truck while touching the outer middle of the board to the grinding surface in the direction from which he or she ollied. Popping and landing on the back truck and touching the inner edge of the board, i.e. popping "over", is known as a feeble grind. Boardslides, lipslides, noseslides, and tailslides are other variations of grinding that are characterized by sliding on an obstacle while balancing on the (usually wooden) deck of the skateboard, rather than on the trucks.

Skateboard ban in Norway
The only country ever to ban skateboards was Norway, in the period between 1978 and 1989. The use, ownership and sale of skateboards were forbidden. The ban was said to be due to the perceived high amount of injuries caused by boards. The ban led skateboarders to construct ramps in the forest and other secluded areas to avoid the police.

Military experimentation in the United States
It has been publicly reported that the United States Marine Corps tested the usefulness of commercial off-the-shelf skateboards during urban combat military exercises in the late 1990s. Their special purpose has been described as "for manuevering inside buildings in order to detect tripwires and sniper fire".

Novice and amateur skate teams
Many novice and amateur skateboarding teams have emerged in the last ten years consisting of groups of talented skateboarders. These are most popular in the USA, where skateboarding started.
