Underwater Rugby
Underwater Rugby (UWR) is an underwater team sport in which two teams compete to deliver a negatively buoyant ball into the opponents’ goal at the bottom of a swimming pool. It originated from physical fitness training programs in German diving clubs during the early 1960s. Recognized by the Confédération Mondiale des Activités Subaquatiques (CMAS) in 1978, it was first played in a world championship in 1980. The sport has little in common with rugby football, except for its name. History In 1961, Ludwig von Bersuda, a member of the German Underwater Club (DUC) in Cologne, conceived the idea of an underwater ball game. Since air-filled balls are unsuitable for underwater games due to buoyancy, von Bersuda experimented with a ball filled with saltwater. Since saltwater is denser than pool water, the ball slowly sinks to the bottom. The sink rate can be controlled within limits by adjusting the concentration of the salt solution. Water polo balls are used instead of l ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Geography Lüdenscheid is located on the saddle of the watershed between the Lenne and Volme rivers which both empty into the Ruhr river (which subsequently flows into the Rhine), with three smaller valleys leading to them. The saddle has a height of 420 meters, higher elevations on the watershed are an unnamed hilltop of 505 meters in the north, and the 663 meters high ''Nordhelle'' in the Ebbe Mountains range. In the surrounding mountainous area, six dams created reservoirs to regulate the water flow in the Ruhr river and supply drinking water. The mountainous nature of the city's territory gave rise to the nickname "Bergstadt" (mountain town). The original settlement circles around the church built on a ledge of the slope above the saddle.
