title: [Torsion movement of the foot in landing after a jump].
abstract: The risk of injury during landing after a jump is considered high, because large moments can force the foot into a distortion. The goals of this investigation were to measure the foot-movements during landing and to check the hypothesis, whether with changes at the shoe sole the rearfoot can be brought into a vertical and therefore stable position during the landing movement. The results show, that during landing the foot twists between forefoot and rearfoot. This movement is referred to as torsion and is described in detail in the anatomical literature. With grooves in the shoe sole the torsion with shoes comes closer to the barefoot values. The rearfoot is stabilized by 5-10 degrees and the risk of injury is decreased.
