Career
He missed the 1992 Summer Olympics in Barcelona because of an injury and came fourth in the 1993 World Championships in Athletics in Stuttgart. This ranks him ninth among German decathletes, behind Jürgen Hingsen, Uwe Freimuth, Siegfried Wentz, Frank Busemann, Torsten Voss, Guido Kratschmer, Paul Meier and Siegfried Stark. Schenk shares the decathlon world record in high jump with Rolf Beilschmidt at 2.27 m.
He was noted for his use of the straddle technique, at a time when the Fosbury flop had become almost universal in competitive high jumping.
