40
Q

What are the 4 types of muscular contraction:

A

1) Isotonic contraction

2) Concentric contraction

3) Eccentric contraction

4) Isometric contraction

41
Q

What is a Isotonic contraction:

A
  • Describes a change in the muscular length caused by movement (split into 2 types of contraction- concentric & eccentric)
42
Q

What is a concentric contraction:

A
  • The muscles become shorter as it undergoes contraction/tension
43
Q

What is a Eccentric contraction:

A
  • The muscle lengthens under tension and acts like a break
44
Q

What is a Isometric contraction:

A
  • Opposite of Isotonic contraction as there is NO movement or change in muscle length as it undergoes contraction
