Ch 7 (5)

Question 1

Sagittal:

Answer 1

an imaginary line bisecting the body into right and left halves (flexion / extension)

Question 2

Frontal:

Answer 2

an imaginary line bisecting the body into anterior and posterior halves (abduction /
adduction)

Question 3

Transverse:

Answer 3

an imaginary line bisecting the body into superior and inferior halves (rotation)

Question 4

Concentric:

Answer 4

muscle action where muscle shortens, think acceleration.

Question 5

Eccentric:

Answer 5

muscle action where muscles lengthen (stronger eccentrically), think negatives in the gym.

Question 6

Isometric:

Answer 6

muscle action where the muscle stays the same length, think plank

Question 7

Isokinetic:

Answer 7

speed of movement is fixed (high-end piece of equipment.)

Question 8

Feed-forward activation:

Answer 8

STABILZATION FACT, certain muscles automatically activate in
anticipation of a movement.

Question 9

Open kinetic chain exercise:

Answer 9

distal segment is moving i.e. leg curl / bench press / lat pull-down

Question 10

Closed kinetic chain exercise:

Answer 10

distal segment is fixed i.e. squats / pull-ups / lunges

Question 11

Altered Reciprocal Inhibition

Answer 11

Agonist receives signal functional antagonist receives inhibitory
signal allowing it to lengthen

Question 12

Stretch Shortening Cycle:

Answer 12

loading of a muscle eccentrically to prep for a rapid contraction (jumping,
NOT TINKERBELL JUMPS) the energy is stored in the series elastic component (tendon) and the transition between the eccentric and concentric portion is rapid and termed amortization

Question 13

Force velocity curve:

Answer 13

As the velocity of a concentric action increases, its ability to produce force
DECREASES; during an eccentric action, as velocity increase, the ability to develop force also INCREASES.

Question 14

First Class Lever:

Answer 14

Nodding the head

Question 15

Second Class Lever:

Answer 15

Plantarflexion / push-up.

Question 16

Third Class Lever:

Answer 16

Biceps Curl. Most limbs in the body are these (hamstring curl

Question 17

Agonist, synergist, stabilizer (always rotator cuff for upper, transverse abs for lower)

Answer 17

.

Question 18

1. An anatomical location referring to a position above a reference point is known as:

Answer 18

Superior

Question 19

2. Which of the following is a third-class lever?

Answer 19

Hamstring Curl

Question 20

3. During a bench press, which muscle(s) are the stabilizers?

Answer 20

Rotator Cuff

Question 21

4.Which of the following is an example of a closed kinetic chain exercise?

Answer 21

Push-Up

Question 22

Answer 22

Going Up Stairs, Squats, RDL, Curls, Triceps, Chin Ups

Question 23

Frontal Examples | Front and Back

Answer 23

Jumping Jacks, Lateral Raise, Band Walks
