Chptr 12 Types of Muscle Contractions
Terms in this set (21)
What are the 3 types of muscle contractions?
Concentric Contraction: muscle shortens
Eccentric Contraction: muscle lengthens
Isometric Contraction: muscle does not move, therefore it does not shorten or lengthen
What is the name given to a muscle that concentrically contracts?
What is the name given to the force that a concentrically contracting muscle must work against?
resistance force - this force is an antagonist to the action (the action of shortening muscle). This force is resisting, antagonizing or trying to stop the shortening muscle contraction.
What type of contraciton occurs when a muscle contracts and shortens?
What type of contraction occurs when a muscle contracts and lengthens?
What type of contraction occurs when a muscle contracts and stays the same length?
Give an example of a resistance exercise.
What defines a muscle contraction?
What type of force is a tensile force?
Do muscles pull or push when they contract?
What does the term gravity neutral mean?
What type of muscle contraction is necessary for a person to flex the arm at the shoulder joint from anatomic position?
What type of muscle contraction is necessary for a person to slowly adduct the arm from a position of 90 degrees of abduction (at the shoulder joint) to anatomic position?
What type of muscle contraction is necessary for a person in anatomic position to rotate the neck to the right at the spinal joints?
What type of muscle contraction is necessary for a person (otherwise in anatomic position) to hold the left thigh in 30 degrees of abduction at the hip joint?
What is the most common scenario in which a muscle eccentrically contracts?
Why might a person contract mover muscles for a joint action that brings a body part downward?
Give an example of an internal force and an external force.
Which type of muscle contraction stops movement from occurring?
Which type of muscle contraction fixes (i.e., stabilizes) a body part in position?
What is the relationship between joint mobility and joint stability?
