Abstract

A hydraulic ergometer for the human foot is described that can apply ankle rotations up to 1 rad at a constant high speed of 10-20 rad/s against moments up to 200 N m. The initial acceleration is damped, so as not to exceed a preset value. With the presented set-up the series elasticity of the intact human m. triceps surae can be measured.
