In this episode, host and NASM Master Instructor Rick Richey, answers a question from a student listener about the sliding filament theory/model of muscle contractions. Rick goes into the detail about the anatomy and characteristics of skeletal muscles, muscle filaments actin and myosin, "force-field proteins" troponin and tropomyosin, cellular currency, and more! He then helps listeners use what we just learned to better understand the length-tension relationships based on limited cross-bridging. Let’s dig deeper into physiology in this episode of the NASM CPT Podcast.
