This review raises the key question of whether the definition of extreme sport is one of risk taking with a high chance of injury or death or if there are more to be considered. Furthermore do factors other than risk, i.e. psychological, socio-demographic and lifestyle, contribute to the defining features of extreme sports?

Secondly, to propose a revised, more accurate definition of extreme sport, reflective of the activities it encompasses in the context of other non-mainstream sports. Based on this review it is argued that a new definition of an ‘extreme sport’ is one of “a competitive (comparison or self-evaluative) activity within which the participant is subjected to natural or unusual physical
