In most extreme sports, athletes perform multiple sporting activities over rugged, often remote, wilderness terrains. These sporting activities may include, but are not limited to, hiking, trail running, mountain biking, caving, technical climbing, fixed-line mountaineering, flat- and white-water boating, and orienteering.
Over the past three decades, the popularity of extreme sports all over the world has grown with increasing numbers of events and participants each year. The provision of on-site medical care during these events is essential to ensure the health and safety of the athletes and thus the success of these sports.
