The roles of muscles
Muscles have different roles when an exercise is carried out, in fact there are multiple muscles working in different ways whenever we move.
| The Antagonist |
The name given to the muscle that relaxes when the prime mover contracts. |
| The Agonist |
The name given to the muscle that is the prime mover for a given joint action. |
| Synergist |
The name given to the muscle that assists the main muscle (prime mover)in bringing about the action. |
| Fixator |
The muscle that contracts to stabilise the part of the body that remains fixed, e.g the trapezius stabilising the shoulder girdle or the transverses abdominus stabilising the vertebrae. |
