    Abstract

    The setting values as indicated on the scale of the toe bindings of 54 World Cup freestyle mogul skiers participating in a World Cup mogul competition in Lillehammer, Norway, were 92% (range 18 to 175%) higher than the ISO (International Organisation of Standardisation) recommended setting values. The estimated torque at which the bindings actually released when tested on-slope with a testing machine was even 15% (range—23 to 143%) higher than the setting value indicated, decreasing to 7% (range—22 to 88%) after the first release. Only 4 of the 54 skiers suggested a setting value within a range of 10% of the ISO recommendations when asked what they believed was the ISO recommended setting value in their own case. The findings of this study suggest that the ISO recommendations play a minor role when adjusting the setting value for release of the toe bindings for World Cup mogul skiers. Moreover, when tested the toe piece of the bindings released not only outside the ISO limits, but also at a higher torque than indicated by the setting values on the visual scale of the toe bindings.
