Anatomy and physiology - Muscular contraction types

Question 1

What are the three types of muscle contractions ?

Answer 1

• Concentric
• Eccentric
• Isometric

Question 2

What happens when there is a concentric muscle contraction ?

Answer 2

• The muscle shortens and develops tension

- Causes join movement (Agonist)

Question 3

What happens when there is a Eccentric muscle contraction?

Answer 3

• The muscle lengthens to develop tension
• Controls the movement
• Downward/Negative phase
• Resist gravity

Question 4

What happens when there is an isometric muscle contraction?

Answer 4

• When a muscle produces tension but stays the same length

- The body is fixed in one position.
