A New Six Component Dynamometer for Measuring Ground Reaction Forces in Alpine Skiing.

This paper describes the development of a new six component dynamometer for measuring ground reaction forces in alpine skiing. Unique of this new dynamometer is its ability to be used with any kind of skiing equipment, its easy adjustability to different boot size and its wireless data transmission. The mechanical construction consists of three parts: the fixation to the boot, the fixation to the binding and the load cell. To measure the loads a mechanically uncoupled assembling of shear beams attached with gauges are mounted in the load cell. Power supply and Bluetooth⠪ module are integrated into the system, data is acquired and stored on an external PDA. [ABSTRACT FROM AUTHOR]
