Chapter 7

Question 1

flexibility

Answer 1

normal extensibility of all soft tissues that allows the full range of motion of a joint

Question 2

extensibility

Answer 2

capability to be elongated or stretch

Question 3

dynamic range of motion

Answer 3

combination of flexibility and nervous system’s ability to control range of motion efficiently

Question 4

relative flexibility

Answer 4

tendency of body to seek path of least resistance during movement

Question 5

muscle imbalance

Answer 5

alteration of muscle length surrounding a joint

Question 6

reciprocal inhibition

Answer 6

simultaneous contraction of a muscle and relaxation of its antagonist

Question 7

altered reciprocal inhibition

Answer 7

tight agonist inhibits functional antagonist

Question 8

synergistic dominance

Answer 8

inappropriate muscles take over function of a weak prime mover

Question 9

arthrokinematics

Answer 9

motions of joints in the body

Question 10

autogenic inhibition

Answer 10

inhibitory effect to muscle spindles (reason behind why stretching works to create muscle extensibility)

Question 11

pattern overload

Answer 11

consistently repeating same pattern of motion may place abnormal stress on body

Question 12

Davis’s law

Answer 12

soft tissue models along the lines of stress

Question 13

static stretching

Answer 13

passively taking a muscle to the point of tension and holding for minimum of 30 sec

Question 14

active-isolated stretching

Answer 14

(at strength level) using agonists and synergists to dynamically move the joint into a range of motion- use same stretches at static but only hold 1-2 sec 5 times

Question 15

dynamic stretching

Answer 15

(power level of athletic competition) active extension of a muscle, using force production and momentum to move the joint through full range of motion
