7 - Human Movement Science

Question 1

Multiplanar movement of the foot and ankle complex consisting of eversion, dorsiflexion, and ankle abduction; associated with force reduction.

Answer 1

Pronation of the foot

Question 2

Multiplanar movement of the foot and ankle complex consisting of inversion, plantar flexion, and ankle adduction; associated with force production.

Answer 2

Supination of the foot

Question 3

Biomechanical motion of the lower extremities during walking, running, and sprinting.

Answer 3

gait

Question 4

When range of motion at a joint is limited.

Answer 4

hypomobility

Question 5

Force is produced, muscle tension is developed, and movement occurs through a given range of motion. Isotonic muscle actions are subdivided into concentric and eccentric muscle actions.

Answer 5

Isotonic

Question 6

The speed of movement is fixed, and resistance varies with the force exerted.

It requires sophisticated training equipment often seen in rehabilitation or exercise physiology laboratories.

Answer 6

Isokinetic

Question 7

A muscle action that occurs when a muscle develops tension while lengthening.

Answer 7

eccentric muscle action

Question 8

A muscle action that occurs when a muscle is exerting force greater than the resistive force, resulting in a shortening of the muscle.

Answer 8

concentric muscle action

Question 9

In order to optimally load muscle during the eccentric phase, the fitness professional should recommend which of the following?

Answer 9

Lower the weight more slowly to increase time under tension

Question 10

What movement term is used to describe the concept of adducting the shoulder blades so that they become closer together?

Answer 10

Scapular retraction

Question 11

Which of the following statements would be accurate with regard to muscle force and velocity during a concentric contraction?

Answer 11

As the velocity of the muscle action increases, its ability to produce force decreases.

Question 12

What scientific term is used to describe the concept whereby a loaded eccentric contraction prepares the muscles for a rapid concentric contraction?

Answer 12

Stretch-shortening cycle

Question 13

The deep longitudinal subsystem includes which of the following muscle groups?

Answer 13

Hamstrings and erector spinae

Question 14

In what plane of movement do shoulder horizontal adduction and abduction occur?

Answer 14

Transverse

Question 15

Performing a biceps curl with a dumbbell in the hand is an example of which type of lever?

Answer 15

Third class

Question 16

Pronation of the foot describes what multiplanar movements?

Answer 16

Eversion, dorsiflexion, and ankle abduction

Question 17

What type of lever could be described as having a fulcrum in the middle like a seesaw?

Answer 17

First class

Question 18

Which of the following muscle groups work eccentrically in the sagittal plane during the lowering phase of the squat?

Answer 18

Quadriceps

Question 19

Performing a biceps curl with a dumbbell in the hand is an example of which type of lever?

Answer 19

Third class
