Chapter 5 Human Movement Science

Question 1

the length-tension relationship (LTR) can best be described as:

Answer 1

the ability of a muscle to produce force at its current rate

Question 2

flexion and extension are two movements that occur in which plane of motion?

Answer 2

sagittal

Question 3

golfing and swinging a bat are both examples of movement that occur in which plane of motion?

Answer 3

transverse

Question 4

science concerned with the internal and external forces acting on the human body and the effects produced by these forces is known as?

Answer 4

biomechanics

Question 5

when a muscle is exerting less force than being placed on it, resulting in the lengthening of the muscle, this is known as what type of contraction?

Answer 5

eccentric

Question 6

when a muscle shortens at a constant speed over the full range of motion, it is known as what type of contraction?

Answer 6

isokinetic

Question 7

where is the right foot in relation to the left hand?

Answer 7

contralateral

Question 8

with which of the following terms is eccentric motion synonymous?

Answer 8

deceleration

Question 9

which of the following is true of an eccentric (deceleration) motion?

Answer 9

it is known as “a negative” in the health and fitness industry

Question 10

which muscle action occurs when a muscle is exerting force greater than the resistive force, resulting in shortening of the muscle?

Answer 10

concentric

Question 11

around which axis does frontal plane motion occur?

Answer 11

anterior- posterior

Question 12

the force- velocity curve describes the relationship between which of the following?

Answer 12

muscle force and the velocity of contraction. As the velocity of a concentric muscle action increases, its ability to produce force decreases

Question 13

bending movement in which the relative angle between two adjacent segments decreases?

Answer 13

flexion

Question 14

what kind of muscle action is raising a dumbbell up against the direction of resistance?

Answer 14

concentric action

Question 15

adduction is a movement back toward the midline of the body in which of the following planes?

Answer 15

frontal plane

Question 16

a client practices repeated squat exercises in order to create permanent changes in her technique, what is she exhibiting?

Answer 16

motor learning

Question 17

as the velocity of a muscular contraction increases, the ability to produce force decreased for which part of the muscle action spectrum?

Answer 17

concentric

Question 18

scapular elevation refers to which of the following motions of the scapula?

Answer 18

superior

Question 19

in which plane of motion does a hammer curl occur?

Answer 19

sagittal

Question 20

horizontal abduction involves the movement of the arm or thigh in the transverse plane from which of the following positions to a lateral position?

Answer 20

anterior

Question 21

what is the hip joint inferior to?

Answer 21

gastrocnemius

Question 22

landing a jump is an example of what kind of motion?

Answer 22

eccentric

Question 23

what term refers to the movement of the arm or thigh in the transverse plane from a lateral position to an anterior position when the joint is in an anteriorly flexed position?

Answer 23

horizontal adduction

Question 24

As the velocity of a muscular contraction increases, the ability to produce force increases for which part of the muscle action spectrum?

Answer 24

eccentric
