Movement Analysis

Question 1

First class lever

Answer 1

Found at the elbow joint

Fulcrum in the middle

Question 2

Second class lever

Answer 2

Found at the ankle

Resistance is in the middle

Question 3

Third class lever

Answer 3

Majority of body’s joints

Effort is in the middle

Question 4

Mechanical advantage

Answer 4

The benefit to a lever system of having either a short effort arm giving rapid movements and a large range of movement , or a short resistance arm hinging the advantage of being able to lift a heavy weight

Question 5

Agonist

Answer 5

The prime mover- muscle that causes movement

Question 6

Antagonist

Answer 6

Muscle that relaxes to allow the agonist to contract

Question 7

Isotonic

Answer 7

Muscle action where muscle changes length- causes movement

Question 8

Isometric

Answer 8

Muscle action where muscle stays the same length- used in balances

Question 9

Concentric

Answer 9

Isotonic contraction where muscle shortens

Question 10

Eccentric

Answer 10

Isotonic contraction where muscle lengthens- used to control downward movements
