New publication online: Muscle mechanics during late stance is the key to explaining maximum running speed

A recently accepted manuscript "Rules of nature’s Formula Run: Muscle mechanics during late stance is the key to explaining maximum running speed" has now been published. Michael Günther, Robert Rockenfeller, Tom Weihmann, Daniel F.B. Haeufle, Thomas Götz, Syn Schmitt. (DOI: https://doi.org/10.1016/j.jtbi.2021.110714). This is a joint work with U Koblenz, U Köln, U Tübingen.

Highlights

  • A biomechanical model for calculating maximum legged running speed is formulated.
  • In the model, air drag equilibrates with horizontal ground reaction force.
  • Ground reaction force is a muscle's force transformed through leg gearing.
  • Maximum legged running speeds across all sizes of animals on earth are predicted.
  • The overall speed maximum is caused by leg muscle inertia rather than fatigue.
  • The impact of body design parameters on running speed is demonstrated.
  • Insight into the emergence of gaits in fast running is provided.
