Biomechanics of Movement | Lecture 4.2: Basic Muscle Properties: Force-Length and Force-Velocity

Lecture by Professor Scott Delp of Stanford University about biomechanics of muscle. Learn about fundamental muscle properties including the force-length and force-velocity relationships. Understanding these muscle properties and relationships helps us to explore how changing biology can affect the force output of a muscle.

The bicycle gear analogy was very good; it well explains the physical mechanism of optimal locomotive velocity.

I presume that the force-length property could be the best explanation to answer why we could push easier than to pull an object
