Group Action of Muscles



Group Action of Muscles: Integrated activity of many muscle groups is required for production of efficient functional movement. They are

i) Agonists: Group of muscles which contract to provide the force required to produce the movement.

ii) Antagonists: These muscles oppose the action of agonists and relax progressively for permitting the movement.

iii) Synergists: These groups of muscles work with agonists to provide a suitable activity and facilitates the movements


iv) Fixators: These muscles stabilize the bones of origin of the agonists and increases their efficiency for production of movement.
