NASM Certified Personal Trainer (CPT) Final Exam Study Guide 1.Proprioception
: The body's ability to to sense the relative position of adjacent parts
of the body
Ex: when walking our feet give us proprioception about the type of
surface we are on.
2.Mechanoreceptors
: specialized structures that recognize pressure in tissue and transmit
signals to sensory nerves.
3.Muscle Spindles
: sensory receptors in the muscles that are parallel to the muscle fibers
and are sensitive to change in muscle length. Spindles stretch with 1 / 3
- /
muscle and sends information to CNS.helps to prevent muscles from stretching too far or too fast 4.Golgi Tendon Organs
: sensory receptors that are located at the point where the skeletal
muscle fibers insert into the tendon. Sensitive to change in tension at the rate of change causes the muscle to relax 5.Epimysium
: connective tissue UNDER fascia that acts as an outer layer of the
whole muscle 6.Perimysium
: connective tissue acts as an outer layer of fascicles
7.Endomysium
: between the individual muscle fibers 2 / 3

8.Type 1 Muscle Fiber
: "slow-twitch", smaller in size, lessforce produced, long-term
contractions (stabilization) 9.Type 2 Muscle Fiber
: fast twitch, larger, quick to fatigue, force and power exer- cises
10.Agonist : PRIME MOVER, main muscles ex: chest press-> pectoralis major 11.Synergist : ASSIST PRIME MOVER, ex: chest press -> ant deltoid, triceps 12.Stabilizer
: stabilizes while prime mover and assist work. chest
press -> rotator cuff 13.Antagonist
