CH 7

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

STABILIZATION FACT, certain muscles automatically activate in anticipation of 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 signals functional antagonist receives inhibitory signal allowing it to lengthen

Question 12

Stretch shortening cycle

Answer 12

Loading of muscle eccentrically to prep for a rapid contraction (jumping, NOT TINKER BELL 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

Bicep curl/ most limbs in the body are these (hamstring curl)
Agonist, synergist, stabilizer (always rotator cuff for upper, transverse abs for lower)
