More recently, the commonly used definition from research is "a competitive (comparison or self-evaluative) activity within which the participant is subjected to natural or unusual physical and mental challenges such as speed, height, depth or natural forces and where fast and accurate cognitive perceptual processing may be required for a successful outcome" by Dr. Rhonda Cohen (2012).
Examples include changing snow conditions for snowboarders, rock and ice quality for climbers, and wave height and shape for surfers.
[11]The Dangerous Sports Club of Oxford University, England was founded by David Kirke, Chris Baker, Ed Hulton and Alan Weston.
Bungee jumping was treated as a novelty for a few years, then became a craze for young people, and is now an established industry for thrill seekers.
The event reached its limits when the Club arrived in St. Moritz with a London double-decker bus, wanting to send it down the ski slopes, and the Swiss resort managers refused.
Kitesurfing on the other hand was conceived by combining the propulsion system of kite buggying (a parafoil) with the bi-directional boards used for wakeboarding.
For example, rugby union is both dangerous and adrenaline-inducing but is not considered an extreme sport due to its traditional image, and because it does not involve high speed or an intention to perform stunts (the aesthetic criteria mentioned above) and also it does not have changing environmental variables for the athletes.
[19][20] Brymer and Gray's study defined 'true' extreme sports as a leisure or recreation activity where the most likely outcome of a mismanaged accident or mistake was death.
The perceived risk in an extreme sport has been considered a somewhat necessary part of its appeal,[25] which is partially a result of pressure for athletes to make more money and provide maximum entertainment.
[28] However, these sports also have the potential to produce drastic benefits on mental and physical health and provide opportunity for individuals to engage fully with life.
[29] It is believed that the implementation of extreme sports on mental health patients improves their perspective and recognition of aspects of life.
According to Sigmund Freud, we have an instinctual 'death wish', which is a subconscious inbuilt desire to destroy ourselves, proving that in the seek for the thrill, danger is considered pleasurable.
