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). • How muscles work (6 min video): • How Muscles REALLY Work: Sliding Fila... • Subscribe: https://www.youtube.com/c/StuartMcErl... • 00:00 Sports Biomechanics Lecture Series • 01:27 Muscle Mechanics Introduction • 03:09 Muscle Structure • 05:38 Three Filament Model • 08:57 Cross-Bridge / Sliding Filament Theory • 12:45 Force-Length Relationship in Muscle • 23:41 Force-Velocity Relationship in Muscle • 35:58 History-Dependent Properties of Muscle • 43:35 Sporting Applications of History-Dependent Muscle Properties • 48:58 Q A (3D Implications, Cycling, Fatigue, Eccentric Contractions, EMG, Modeling, Training, and More) • Links to muscle mechanics review papers: • Herzog, 2018: https://doi.org/10.1007/s12551-017-03... • Herzog et al., 2016: https://doi.org/10.1152/physiol.00049... • Web: https://www.stuartmcnaylor.com/sports... • Audio: https://www.stuartmcnaylor.com/podbean/ • Twitter: / biomechstu • Monthly research newsletter: https://www.stuartmcnaylor.com/newsle...
