[Carving and ski technique--aspects of biological regulation]

Based on theoretical calculations the effects of skis with great sidecuts on the biological regulation are shown. Of main interest is the overload of the biological system by unexpectedly catching an edge. The calculations show that a great sidecut using the same edge ankle causes a greater lateral deviation compared to a normal ski. The correction of unexpected incidents is done by reflex mechanisms. Remarkable consequences for the reflex time can be calculated for the various sidecuts only. It can be concluded that problems in using carving skis mainly occur in combining high velocities and/or weak movement experiences.
