MUSCLE CONTROL

TYPES OF CONTRACTIONS

CONCENTRIC: The shortening of a muscle whilst creating tension
ECCENTRIC : The lengthening of a muscle whilst creating tension
ISOMETRIC: Muscle length stays the same whilst creating tension

MUSCLE CONTROL

AGONIST: Known as the prime mover, the agonist is the muscle which creates movement.

ANTAGONIST: Plays the opposite role to the agonist, the antagonist muscle relaxes or opposes the agonist to create a better contraction. It can play different roles, for one it can relax the agonist, secondly it can create some tension to prevent injury or it can contract fully to add precision and control to the movement.

NEUTRALIZER: Prevents any irrelevant action created by the agonist.

FIXATOR: The fixator muscle contracts to keep other areas stable.

SYNERGIST: Known to assist the agonist muscle when contracting.
