What are the 4 types of muscular contraction:
1) Isotonic contraction
2) Concentric contraction
3) Eccentric contraction
4) Isometric contraction
What is a Isotonic contraction:
- Describes a change in the muscular length caused by movement (split into 2 types of contraction- concentric & eccentric)
What is a concentric contraction:
- The muscles become shorter as it undergoes contraction/tension
What is a Eccentric contraction:
- The muscle lengthens under tension and acts like a break
What is a Isometric contraction:
- Opposite of Isotonic contraction as there is NO movement or change in muscle length as it undergoes contraction
