Death diving, also known as Dødsing, is a form of extreme freestyle diving from heights where the diver jumps with stretched arms and belly first, landing in a cannonball or a shrimp position. The roots of death diving are in Norway, where Døds events still dominate. There are two classes of death diving: Classic and Freestyle. In the Classic event, competitors fly horizontally with their arms and legs extended until they hit the water, with no rotations. Competitors curl into a fetal position just before entering the water, landing first with their feet and hands or knees and elbows to avoid serious injury. Dives are judged on speed, air time, complexity, how long the diver holds the original pose, the closing, and the splash. The Døds Diving World Championship is the pinnacle event of the sport of death diving, and has taken place in Oslo, Norway every August since it debuted in 2008 as the first official death diving competition on the global stage. Death diving is considered an extreme sport and can be dangerous, as divers can suffer injuries from the impact of hitting the water.
