Skateboarding

Is the act of ride and make tricks using a skateboard, the person who skateboards are called skateboarder or skater. The skateboarding can be a sport, an art, a job, or can be used for transportation.
Skateboarding is relatively modern. The basic trick in skateboarding is called Ollie, the Ollie was developed in the 70s by Alan “Ollie” Gelfand as a half-pipe maneuver, and then born the freestyle by Rodney Mullen, and he was the first to take it in the ground and later invented the kick flip and an other variations.
The first manufactured skateboards were ordered by a Los Angeles, California surf shop, meant to be used by surfers in their downtime. The shop owner, Bill Richard, made a deal with the Chicago Roller Skate Company to produce sets of skate wheels, which they attached to square wooden boards. Accordingly, skateboarding was originally denoted "sidewalk surfing" and early skaters emulated surfing style and maneuvers. Crate scooters preceded skateboards, and were borne of a similar concept, with the exception of having a wooden crate attached to the nose front of the board, which formed rudimentary handlebars.
With the evolution of skate parks and ramp skating, the skateboard began to change. Early skate tricks had consisted mainly of two-dimensional manoeuvres like riding on only two wheels, spinning only on the back wheels, high jumping over a bar and landing on the board again, also known as a "hippie jump", long jumping from one board to another.
The use of skateboards solely as a form of transportation is often associated with the long board. 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.
Skateboards, along with other small wheeled transportation such as in line skates and scooters, suffer a safety caveat where riders may easily be thrown from small cracks and outcroppings in pavement, especially where the cracks run perpendicular to the direction of travel. However, high average travel speeds help mitigate this; injuries are more likely to be minor, although very uncommon, head injuries still pose a major health risk.
