Many people believe that extreme sports are all about marketing. The actual perception of them along with their definition has changed over the years. For instance sports such as scuba diving, mountaineering and storm chasing are no longer considered extreme sports these days while they were considered as extreme sports during the 80s.
Bungee jumping is one good example for this change in perception. When it was first invented the sport soared in popularity as an extreme sport which could be done by only a very few trained professionals. This myth was broken when more and more people began to take up the sport, just for fun or for the adrenaline rush. These days many extreme sports are targeted at the youth. The advertisements that promote these sports are almost always targeted at the youth. They would typically have youth with their favorite styles of music and clothing.
Perhaps the major reason why these sports are popular is because of the kind of adrenaline rush that they provide. However there are other theories being floated by the medical fraternity which say that this high is not due to adrenaline rush. These experts are of the opinion that the feeling of high is due to the increased levels of serotonin, endorphins and dopamine, which are released due to the very high level of physical exertion.
