Three Types of Muscle - ANS 1. Skeletal 2. Cardiac 3. Smooth 2 forms of Hypertrophy - ANS 1. In series 2. In parallel Primary mechanism for hypertrophy associated with resistance training - ANS Increase in number of sarcomeres in parallel How is in series hypertrophy achieved - ANS Increasing the number of sarcomeres- basic functional unit of muscle- along length of fiber Though in series hypertrophy does take place in humans, it only occurs in extreme cases such as - ANS Following immobilization of a joint by a cast or By performing very long duration incline treadmill walking How is in parallel hypertrophy achieved? - ANS When sarcomeres (basic functional unit of muscle) are added next to each other (Muscle cross-sectional area is increased) (Produces thicker/fuller muscle) Maximal muscular strength v Hypertrophy - ANS Maximal muscular strength: Ability to lift heavy loads Substantial neurological component (By enhancing various neurological factors, an individual is better able to produce optimal force... the nervous system sends faster and stronger electrical signals to muscles to increase strength) Hypertrophy is regulated by a number of intracellular factors (factors within the cell) Sarcomere - ANS Contractile unit of muscle Muscle hypertrophy is ultimately a function of what? - ANS Protein balance - synthesize more muscle proteins than you break down and you will pack on size Three mechanisms involved in exercise-induced muscle hypertrophy - ANS 1. Mechanical tension 2. Muscle damage 3. Metabolic stress Mechanical Tension - ANS The amount of force developed by muscle fibers in response to a stimulus
