    Abstract

    The release bindings of 376 alpine ski racers have been examined by onslope recordings of the lateral toe release torques. The skiers were randomly selected from the participants of seven alpine competitions arranged in Norway during the winters of 1982 and 1983. Several bindings displayed release torques that deviated significantly from the binding settings. The mean deviation was 6% (P < 0.001), but the dispersion was considerable (range: −71 to 125%). About 40% of the bindings released in accordance with the setting (±10%), and 7% released for values 50% beyond the setting. The deviation of binding release from binding setting increased with increasing binding age and with increased frequency of bindings with insufficient lug clearance at the toepiece (the binding front safe was mounted too low). The mean binding release/setting deviation varied with the binding models tested but was negligible for bindings self-release tested the same week. In conclusion, alpine bindings should be properly mounted and adjusted, be of a relatively recent age, and self-release tested every day before skiing to prevent an unintentional high release level.
