Skateboarding is the act of riding and performing tricks using a skateboard. A person who skateboards is most often referred to as a skateboarder, or just skater.
Skateboarding can be a recreational activity, an artform, a job, or a method of transportation. Skateboarding has been shaped and influenced by many skateboarders throughout the years. A 2002 report by American Sports Data 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.
Skateboarding is relatively modern. A key skateboarding maneuver, the ollie, was developed in the late 1970s by Alan “Ollie” Gelfand as a half-pipe maneuver. Freestyle skateboarder Rodney Mullen was the first to take it to flat ground and later invented the kickflip and its variations.
Freestyle slalom skating is a highly technical field of skating that involves performing tricks around a straight line of equally spaced cones.
Most freestyle slalomers use inline skates although some use quad skates. Those who use inline skates tend to use a full rocker wheel configuration and a short frame (230-245mm) to give them the maximum possible maneuverability. The inline skates are very tight with a very strong cuff, to give sustaining ankle support.
