Chapter 7: Human Movement Science

Question 1

Kinesiology

Answer 1

Study of movement through anatomy and physiology.

Question 2

Agonists

Answer 2

Primary muscle providing force.

Question 3

Synergists

Answer 3

Secondary Muscles helping Agonist

Question 4

Feed-Forward Activation

Answer 4

When a muscle is automatically activated during a movement.

Question 5

Antagonists

Answer 5

Muscles on the opposite side of agonist muscles.

Question 6

Reciprocal Inhibition

Answer 6

When agonist receives signal to contract, and antagonist to lengthen.

Question 7

Altered Reciprocal Inhibition

Answer 7

When overactive agonist muscle decreases neural drive to antagonist.

Question 8

Altered Length-Tension Relationship

Answer 8

Muscle’s resting length is too short or too long which reduces the force it can produce.

Question 9

Stretch-Shortening Cycle

Answer 9

Loading muscle eccentrically to prepare for a quick concentric contraction.

Question 10

Force-Couple Relationship

Answer 10

The synergistic action of multiple muscles working together to produce movement around a joint.

Question 11

Torque

Answer 11

A movement that produces rotation

Question 12

Neuromuscular Efficiency

Answer 12

Ability of nervous system to recruit the correct muscles to produce force, reduce force, and dynamically stabilize the body in all three planes of motion.
