Impulsive ankle push-off powers leg swing in human walking

SW Lipfert, M Günther, D Renjewski… - Journal of …, 2014 - journals.biologists.com
Rapid unloading and a peak in power output of the ankle joint have been widely observed
during push-off in human walking. Model-based studies hypothesize that this push-off …

Compliant ankle function results in landing-take off asymmetry in legged locomotion

D Maykranz, A Seyfarth - Journal of theoretical biology, 2014 - Elsevier
The spring loaded inverted pendulum (SLIP) model is widely used to predict and explain

Foot function enabled by human walking dynamics

D Renjewski, S Lipfert, M Günther - Physical Review E, 2022 - APS
Bipedal walking, the habitual gait for man, is rather unique in nature and poses particular
challenges for balance and propulsion. The characteristic double-humped ground reaction …

Dynamic force measurements for a high bar using 3D motion capturing

C Cagran, P Huber, W Müller - Journal of biomechanics, 2010 - Elsevier
The displacement of a calibrated horizontal bar is used as a measure for forces acting on the
bar itself during dynamic performances in artistic gymnastics. The high bar is loaded with …

What does head movement tell about the minimum number of mechanical degrees of freedom in quiet human stance?

M Günther, O Müller, R Blickhan - Archive of Applied Mechanics, 2012 - Springer
In this study, we checked experimentally whether anterior–posterior accelerations of the
head during quiet human stance are usually below or above known thresholds of the otolith …
