Skateboard
โ€ข Skateboarding is an action sport which 
involves riding and performing tricks using 
a skateboard. Skateboarding can also be 
considered a recreational activity, an art form, 
a job, or a method of transportation. 
โ€ข Skateboarding has been shaped and 
influenced by many skateboarders throughout 
the years. A 2002 report found that there 
were 18.5 million skateboarders in the world. 
85 percent of skateboarders polled who had 
used a board in the last year were under the 
age of 18, and 74 percent were male.
โ€ข Since the 1970s, skateparks have been 
constructed specifically for use by 
skateboarders, Freestyle 
BMXers, aggressive skaters, and very 
recently, scooters.
โ€ข Skateboarding was probably born sometime in 
the late 1940s or early 1950s when surfers 
in California wanted something to surf when 
the waves were flat. No one knows who made 
the first board; it seems that several people 
came up with similar ideas at around the 
same time. These first skateboarders started 
with wooden boxes or boards with roller skate 
wheels attached to the bottom.
โ€ข In the early 1970s, Frank Nasworthy started to 
develop a skateboard wheel made of 
polyurethane, calling his company Cadillac 
Wheels. Prior to this new material, 
skateboards wheels were metal or "clay" 
wheels. The improvement in traction and 
performance was so immense that from the 
wheel's release in 1972 the popularity of 
skateboarding started to rise rapidly again, 
causing companies to invest more in product 
development.
โ€ข This period 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 Florida in 1976, and the almost 
parallel development of the grabbed aerial 
by George Orton and Tony Alva in California, 
made it possible for skaters to perform airs on 
vertical ramps.
โ€ข Skateboarding during the 1990s became 
dominated by street skateboarding. Most 
boards are about 7 1โ„4 to 8 inches (180 to 
200 mm) wide and 30 to 32 inches (760 to 
810 mm) long. The wheels are made of an 
extremely hard polyurethane, with hardness 
(durometer) approximately 99A. The wheel 
sizes are relatively small so that the boards are 
lighter, and the wheels' inertia is overcome 
quicker, thus making tricks more manageable.
โ€ข By 2001 skateboarding had gained in such 
popularity, that more participants under the age 
of 18 rode skateboards (10.6 million) than played 
baseball (8.2 million), although traditional 
organized team sports still dominated youth 
programs overall. Skateboarding and skateparks 
began to be viewed and used in a variety of new 
ways to compliment academic lessons in schools, 
including new non-traditional physical education 
skateboarding programs, like Skatepass and 
Skateistan that are used to encourage youth to 
have better attendance, self-discipline and 
confidence.
โ€ข With the evolution of skateparks and ramp 
skating, the skateboard began to change. Early 
skate tricks had consisted mainly of two-dimensional 
freestyle manoeuvres like riding 
on only two wheels ("wheelie" or "manual"), 
spinning only on the back wheels (a "pivot"), 
high jumping over a bar and landing on the 
board again, also known as a "hippie jump", 
long jumping from one board to another, 
(often over small barrels or fearless 
teenagers), or slalom. Another popular trick 
was the Bertlemann slide, named after Larry 
Bertelemann's surfing manoeuvres.
โ€ข Skateboarding was popularized by the 1986 
skateboarding cult classic Thrashin'. Directed 
by David Winters and starring Josh Brolin, it 
features appearances from many famous skaters 
such as Tony Alva, Tony Hawk, Christian 
Hosoi and Steve Caballero. Thrashin' also had a 
direct impact on Lords of Dogtown, as Catherine 
Hardwicke, who directed Lords of Dogtown, was 
hired by Winters to work on Thrashin' as 
a production designer where she met, worked with 
and befriended many famous skaters including the 
real Tony Alva, Tony Hawk, Christian 
Hosoi and Steve Caballero.
โ€ข Skateboarding was, at first, tied to the culture 
of surfing. As skateboarding spread across 
the United States to places unfamiliar with 
surfing or surfing culture, it developed an 
image of its own. For example, the classic film 
short Video Days(1991) portrayed 
skateboarders as reckless rebels.
โ€ข One of the early leading trends associated 
with the sub-culture of skateboarding itself, 
was the sticky sole "Slip-On" Skate shoe, most 
popularized by Sean Penn's skateboarding 
character from the film Fast Times at 
Ridgemont High. Because early skateboarders 
were actually surfers trying to emulate the 
sport of surfing, at the time when skateboards 
first came out on the market, many 
skateboarded barefoot.
โ€ข But skaters often lacked traction, which led to 
foot injuries. This necessitated the need for a 
shoe that was specifically designed and 
marketed for skateboarding, such as the 
Randy "720", manufactured by the Randolph 
Rubber Company, and Vans sneakers, which 
eventually became cultural iconic signifiers for 
skateboarders during the 70s & 80's as 
skateboarding became more widespread.
โ€ข Skateboards, along with other small-wheeled 
transportation such as in-line skates and 
scooters, suffer a safety problem: riders may 
easily be thrown from small cracks and 
outcroppings in pavement, especially where 
the cracks run across the direction of travel. 
Hitting such an irregularity is the major cause 
of falls and injuries. The risk may be reduced 
at higher travel speeds.
โ€ข Transportation 
โ€ข The use of skateboards solely as a form of 
transportation is often associated with 
the longboard. Depending on local laws, using 
skateboards as a form of transportation 
outside residential areas may or may not be 
legal. Backers cite portability, exercise, and 
environmental friendliness as some of the 
benefits of skateboarding as an alternative to 
automobiles.
โ€ข Military 
โ€ข The United States Marine Corps tested the 
usefulness of commercial off-the-shelf 
skateboards during urban combat military 
exercises in the late 1990s in a program called 
Urban Warrior '99. Their special purpose was 
"for maneuvering inside buildings in order to 
detect tripwires and sniper fire.
โ€ข Trampboarding 
โ€ข Trampboarding is a variant of skateboarding 
that uses a board without the trucks and the 
wheels on a trampoline. Using the bounce of 
the trampoline gives height to perform tricks, 
whereas in skateboarding you need to make 
the height by performing an Ollie. 
Trampboarding is seen on YouTube in 
numerous videos.
โ€ข Swing boarding 
โ€ข Swing boarding is the activity where a 
skateboard deck is suspended from a pivot 
point above the rider which allows the rider to 
swing about that pivot point. The board 
swings in an arc which is a similar movement 
to riding a half pipe. The incorporation of a 
harness and frame allows the rider to perform 
turns spins all while flying though the air.
โ€ข Skateboarding is sometimes associated with 
property damage to urban terrain features 
such as curbs, benches, and ledges when 
skateboarders perform tricks known as grinds 
on these surfaces. Private industry has 
responded to this perceived damage with 
skate deterrent devices, such as 
the Skatestopper, in an effort to mitigate 
damage and discourage skateboarding on 
these surfaces.
