Sliding Filament Theory Part 2 NSCA Certification HD

http://www.personaltrainerexam.com/ This is part 2 of the sliding filament theory of muscle contraction. I made this to help me study for the NSCA Certification. I plan on getting my CSCS and CPT Certification.This video talks about the 5 phases of the sliding filament theory. It will also show some pictures of actin, tropomyosin, troponin and myosin cross bridges. Here is part of the outline for part 2 to follow along with : 5 Phases of the Sliding Filament Theory of Muscular Contraction Resting Phase Excitation-Contraction Coupling Phase Contraction Phase Recharge Phase Relaxation Phase *Remember-there are 5 phases 1. Resting Phase The muscle is not being stimulated by the motor neuron so the muscle is at rest. 2. Excitation-Contraction Coupling Phase Calcium is released into the myofibril Calcium attaches to troponin, which causes the shifting of tropomyosin and exposing the active binding sites on the actin molecule.
