Some exameples are: skateboarding, inline skating, snowboarding, or one of the more extremer sports, such as Moto X, skysurfing and kytesurfing.\n\nExtreme sport (practically synonymous with the term action sport) is a general term for sports featuring speed, height, danger or spectacular stunts. A feature of such activities in the view of some is their alleged capacity to induce a so-called ‘‘adrenaline rush’’ in participants (a misnomer, since often the rush or high obtained is a product of increased levels of dopamine endorphins and serotonin).\n\nExtreme sports are often associated with young adults wishing to push themselves to the limits of their physical ability and fear, in turn pushing the boundaries of a particular sport. This youthful demographic accounts too for extreme sports’ frequent association with youth culture, not restricted to clothing fashions and music.\n\nSome contend that the distinction between an extreme sport and a conventional one is as much to do with marketing as it is to do with perceptions about levels of danger involved or the amount of adrenaline generated. Snowboarding thus has a more extreme ‘‘image’’ than skiing due to differing marketing strategies and the fact of being a newer sport, even though skiing is a faster and at least equally dangerous activity.
