Domain 1: Human Movement Science

Front 1

Concentric

Back 1

Moving in opposite direction of force, accelerates or produces four; muscle shortens

Front 2

Eccentric

Back 2

Also developed attention while lengthening; decelerates force

Front 3

Isometric

Back 3

Muscular force equal to resistive force, stabilizes force; no change in muscle length

Front 4

Length – tension relationsh

Back 4

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

Front 5

Force-couple

Back 5

Muscles working together to produce movement

Front 6

Force – velocity curve

Back 6

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

Front 7

Neuromuscular efficiency

Back 7

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

Front 8

Structural efficiency

Back 8

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

Front 9

Davis’s law

Back 9

Soft tissue models along the lines of stress

Front 10

Autogenic inhibition

Back 10

Neural impulses that sense tension are greater than the impulses that cause muscles to contract; provides inhibitory effect to muscle spindles

Front 11

Reciprocal inhibition

Back 11

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

Front 12

Relativs flexibility

Back 12

Tendency of the body to seek the path of least resistance

Front 13

Pattern overload

Back 13

Consistently repeating the same motion; places abnormal stress on the body

Front 14

Postural distortion patterns

Back 14

Predictable patterns of muscle imbalances

Front 15

Altered reciprocal inhibition

Back 15

Muscle in addition caused by a tight agonist, which inhibits it’s functional antagonist

Front 16

Synergistic dominance

Back 16

Inappropriate muscle takes over function of a weak or inhibited prime mover

Front 17

Muscle imbalance

Back 17

Alteration of muscle length surrounding a joint
