In connection with theoretical calculations concerning the influence of the sidecut of a ski on skiing behaviour, results of different field and laboratory research to the neuromuscular regulation are discussed in this study. The calculations show that a greater sidecut under identical conditions regarding edge angle and velocity causes a greater lateral deviation which is hardly corrigible. In addition, indispensible regulatory processes are complicated by additional vibration loads. However, it appears that a higher basic overall and local muscle-stiffness helps to prevent danger situations resulting from edge over and cutting edge. The pre-innervated musculature can react faster and more effectively to sudden lateral deviations. Studies with world class and junior athletes during straigth gliding showed that the subtle regulation in the ankle-joint is trainable to a considerable degree. Verf.-Referat
