Abstract

The AGAINER is a shock absorbing exoskeleton for skiing. It provides a dampening and support at the knees using an adjustable gas spring. The AGAINER is one of the first commercial exoskeletons designed with a very specific application in mind, skiing. It is a passive, knee only exoskeleton. The AGAINER takes advantage of the rigid boots that skiers have to wear in order to connect to their skis and integrates them as part of the exoskeleton. How AGAINER’s adjustable gas springs act on the body was tested by measuring electromyography. The measurements were first performed on flat ground, and then compared with the device on and off during vertical bending movements. Next, they performed parallel turns on the snow with and without the device. The results showed that wearing the device reduced the load on the vastus lateralis muscle.
