e-SKI - The Principle of Maximum Effectiveness and Efficiency

Similar to the electrification of bicycles, motorised ascent assistance systems are emerging in ski touring. The e-SKI module is biomechanically evaluated regarding efficiency and reduction of physical effort and compared with an existing exoskeleton-based ascent system.

Description

In standardized treadmill tests, participants use both the e-SKI module and Hypershell under identical conditions.

EMG, motion analysis, and spirometry quantify differences in

muscle activity,
movement economy, and
physiological load

to assess efficiency and identify optimization potential for the e-SKI-Module.
