What type of muscle is the primary mover in a muscle contraction that provides the work in a muscle contraction?
Agonist
What type of muscle opposes the primary mover?
Antagonist
What type of muscle inhibits the contraction of another muscle?
Neutralizer
What type of muscle assists other muscles by fixing a specific joint in place?
Stabilizer
What enhances the movement of another muscle?
Synergist
Isokinetic & Isotonic are what type of contractions?
Dynamic
Name the 6 types of muscle contractions.
- Isometric
- Isokinetic
- Isotonic
- Concentric
- Eccentric
Concentric & Eccentric contractions are in what muscle contraction category?
Isotonic contraction
Contractions producing tension within the muscle without a change in length of fiber are known as…?
Isometric contraction
Contraction that is the same or controlled speed of movement is…?
Isokinetic contraction
Constant resistance of force in which both eccentric & concentric movements occur is known as…?
Isotonic contraction
What is the characteristic of dynamic muscular actions?
The muscle fibers either shorten or lengthen
A contraction of a muscle in which the muscle fiber shortens is…?
Concentric
A muscle in which the fibers lengthen is…?
Eccentric
