Muscle Action Spectrum

Question 1

Concentric

Answer 1

Muscular force greater than resistive force; muscle shortens

Question 2

Eccentric

Answer 2

Muscle develops tension while lengthening; decelerates force

Question 3

Isometric

Answer 3

Muscular force to resistive force; no change in muscle length

Question 4

Length- Tension Relationship

Answer 4

Resting length of a muscle and the tension it can produce at that length

Question 5

Force- Couple

Answer 5

Muscles working together to produce movement

Question 6

Force- Velocity Curve

Answer 6

As the velocity of a contraction increases, concentric force decreases and eccentric force increases

Question 7

Neuromuscular Efficiency

Answer 7

Ability to produce and reduce force and stabilize the kinetic chain in all three planes of motion

Question 8

Structural Efficiency

Answer 8

Alignment of the musculoskeletal system that allows center of gravity to be maintained over a base of support

Question 9

Davis’s Law

Answer 9

Soft tissue models alone the lines of stress

Question 10

Autogenic Inhibition

Answer 10

When neutral impulses that sense tension are greater than the impulses that cause muscles to contract; inhibits muscle spindles

Question 11

Reciprocal Inhibition

Answer 11

Simultaneous contraction of one muscle, and relaxation of it antagonist to allow movement.

Question 12

Relative Flexibility

Answer 12

Tendency of the body to seek the path of least resistance

Question 13

Pattern Overload

Answer 13

Consistently repeating the same motion; places abnormal stresses on the body.

Question 14

Postural Distortion Patterns

Answer 14

Predictable patterns of muscle imbalances

Question 15

Altered reciprocal inhibition

Answer 15

Muscle inhibition cause by a tight agonist. which inhibits its functional antagonist

Question 16

Synergistic Dominance

Answer 16

Synergist takes over function for a weak or inhibited prime mover

Question 17

Muscle Imbalance

Answer 17

Alteration of muscle length surrounding a joint
