3 Types Of Muscle Contraction

Question 1

What are the 3 types?

Answer 1

Concentric, eccentric, and isometric

Question 2

Concentric

Answer 2

Muscle contracts and shortens to pull up on a skeletal bone. Movement: flexion decreases the angle at a joint.
Muscle force is greater than the resistance

Question 3

Eccentric

Answer 3

Muscle contracts and lengthens to control the lowering of a skeletal bone. Movement: extension increases the angle of the joint.
Muscle force is less than the resistance.

Question 4

Isometric

Answer 4

Muscle contracts but does not changes its length to keep a bone motionless. Movement: no motion to the angle of a joint.
Muscle force is equal to the resistance.
