Document Summary
Sliding filament theory how actin and myosin slide pass each other to produce force that allows muscles to produce movement and contraction. Page 48- muscle memory research perspective box!!! Primary tool that we use in physiology to take muscle samples to study the skeletal muscle (can do this to all types of people- sedentary and athletes and all others) The muscle biopsy in exercise physiology: research tool, not a medical biopsy for kidney or liver and so on. History of biopsy: ducschans muscular dystrophy, neurologist that characterized dystrophy abnormality in skeletal muscle, all the skeletal muscle have a defect that cause them to lose their functional ability. Inject anesthesia into that area, make an incision with a scapula at the midpoint of the muscle, and take biopsy needed and insert it into the muscle. Tell subject to tell technician when they feel a muscle contraction, and when they do, you know you are in the right place.
