Document Summary

Insertion: attachment site of a muscle that does move during contraction i. e. biceps brachii long head insertion is the radial tuberosity of radius, know the actions of muscles (abductors, adductors, etc) Moves limb away from the midline of the body. Moves limb toward the midline of the body. What occurs during a power stroke: know the function of these muscle proteins: troponin, tropomyosin, titin, myosin, actin (which is the thick/thin filament?). Isotonic contraction muscle contraction in which the muscle shortens in length and maintains roughly the same amount of tension throughout the shortening process. Enzymes: allows them to metabolize glucose anaerobically (lactic acid fermentation) to produce atp, type iix fibers have the greatest rate of atp consumption and fastest rate of atp and phosphocreatine depletion. Intermediate fast-twitch fiber: categorized as fast-twitch fibers, but also have high oxidative capacity, makes them more resistant to fatigue, aka fast oxidative glycolytic fibers, type iia fibers.
