Ski Binding Settings Based on Anthropometric and Biomechanical Data

Abstract

The international standard for setting ski bindings is based on the measurement of the tibia proximal width (the width of the shin bone just below theknee) because of the propensity of this bone to suffer trauma as the ski and skier attempt to go in different directions. This is shown to be an invalid measurement. The actual proximal width can be corrected by a formula based on multiple regression of height, weight, and measured proximal width. A nomograph of this equation, suitable for use in setting release levels on a binding is given. Other anthropometric variables (the length and midshaft diameter of the tibia and wrist, chest, and waist circumferences) were found to be unsuitable as predictors of actual proximal width.
