Lecture 28 of the Sports Biomechanics Lecture Series #SportsBiomLS 
Walter Herzog presents a lecture on the fundamentals of muscle mechanics. This includes: basic structure of muscles and sarcomeres; the sliding filament, cross-bridge and three filament model of muscle contraction; and how these muscle mechanics models relate to the force-length relationship, force-velocity relationship, and force-time properties of muscle (with sporting examples).
