Rationales Included
, 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 muscle and sends
information to CNS.
helps to prevent muscles from stretching too far or too fast
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
Epimysium connective tissue UNDER fascia that acts as an outer layer of the whole muscle
Perimysium connective tissue acts as an outer layer of fascicles
Endomysium between the individual muscle fibers
Type 1 Muscle Fiber "slow-twitch", smaller in size, lessforce produced, long-term contractions
(stabilization)
Type 2 Muscle Fiber fast twitch, larger, quick to fatigue, force and power exercises
Agonist PRIME MOVER, main muscles
ex: chest press-> pectoralis major
Synergist ASSIST PRIME MOVER,
ex: chest press -> ant deltoid, triceps
Stabilizer stabilizes while prime mover and assist work.
chest press -> rotator cuff
Antagonist Oppose Prime mover,
chest press -> posterior delt
