Movement Flashcards
What occurs when a muscle develops tension while lengthening
A) isometric
B) isokinetic
C) eccentric
D) concentric
C) Eccentric Muscle “easier”
What occurs when the contractile force is greater than the resistive force, resulting in a visible Shortening of the muscle?
A) isometric
B) isokinetic
C) eccentric
D) concentric
D) Concentric “harder”
What occurs when the contractile force is equal to the resistive force, leading to no visible change in the muscle length?
A) isometric
B) isokinetic
C) eccentric
D) concentric
A) isometric
What is it called when a muscle shortens at a constant speed over the full Rom?
A) concentric
B) eccentric
C) isokinetic
D) isometric
C) Isokinetic
When a muscles resting length is too short or too long, reducing the amount of force it can produce
A) sarcomere
B) reciprocal inhibition
C) altered length tension relationship
D) actin
Altered length-tension relationship
What are closed chain movements? Give example
Persons hands or feet are stationary
Example: back squat and pull up
What are open chain movements? Give example
Hand and feet are not fixed in one place.
Seated bicep curls
Tend to focus on isolating the primer mover muscles
Thin, stringlike, myofilament that acts along with myosin to produce muscular contraction
A) sarcomere
B) reciprocal inhibition
C) altered length tension relationship
D) actin
D) actin
What is the structural unit of a myofribil composed of actin and myosin filaments between two z-lines
A) sarcomere
B) reciprocal inhibition
C) altered length tension relationship
D) actin
A) sarcomere
What is an agonist receives a swig all to contract, it’s functional antagonist also receives an inhibitory signal allowing it to lengthen?
A) sarcomere
B) reciprocal inhibition
C) altered length tension relationship
D) actin
B) reciprocal inhibition
Loading of a muscle eccentrically to prepare it for a rapid concentric contraction
Stretch shortening cycle
