Five movement skills with rationales for each movement skills for which a high percentage of fast-twitch fibers is an asset and five movement skills with rationales for each movement skills for which a high percentage of slow-twitch fibers is an asset. Concept introduction: The muscle fibers contain bundles of myofibrils that are arranged in parallel along with the longitudinal axis. They also include myofibrils, muscle membrane, sarcoplasm, sarcotubular system, and mitochondria. There are two types of muscle fibers that are type I and type II.

We move a lot and do not even realize how intricate these movements may be from gross motor to fine motor manipulations. Briefly explain the steps involved in a single muscle contraction beginning at the neuromuscular junction through one complete contraction and relaxation for the sliding filament theory. Don’t forget to include all the major proteins (actin, myosin, troponin and tropomyosin) involved as well as calcium and ATP.
