- Three Types of Muscle
: 1. Skeletal
- Cardiac
- Smooth
- 2 forms of Hypertrophy
: 1. In series
- In parallel
- Primary mechanism for hypertrophy associated with resistance training
: -
Increase in number of sarcomeres in parallel
- How is in series hypertrophy achieved
- / 3

: 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
: Following immobilization of a joint by a cast
or
By performing very long duration incline treadmill walking
- How is in parallel hypertrophy achieved
?: 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
: Maximal muscular strength:
Ability to lift heavy loads Substantial neurological component (By enhancing various neurological factors, an 2 / 3
- / 9
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
: Contractile unit of muscle
- Muscle hypertrophy is ultimately a function of what
?: Protein balance - syn- thesize more muscle proteins than you break down and
you will pack on size
- Three mechanisms involved in exercise-induced muscle hypertrophy
: 1. Mechanical tension
- Muscle damage
- Metabolic stress
- Mechanical Tension
: The amount of force developed by muscle fibers in re- sponse to a stimulus
