Sandra Köppen

Sandra Köppen was a German three-time Olympian heavyweight judoka. She finished tied fifth at Sydney in 2000 and was eliminated in the pool stage at both Athens in 2004 and Beijing in 2008. In 2001 and 2002, Köppen won the European Championships, and she added three bronze medals in 1998-99, 2003. She also won bronze medals at the 2001 and 2007 Worlds.

Since 1998, Köppen started sumo wrestling alongside her judo. She won four Sumo World Championship titles in 1999, 2001, and 2004-05, and team golds in 2001 and 2004. Köppen won a gold at the World Games in 2005. Köppen trained as a medical assistant but later turned to coaching both judo and sumo. In 2013 she partly needed a wheelchair as both of her knees needed protheses, but she subsequently recovered.
