Antagonist and agonist muscles often occur in pairs, called antagonistic pairs. As one muscle contracts, the other relaxes. An example of an antagonisic pair is the biceps and triceps; to contract-the triceps relaxes while the biceps contracts to lift the arm.ntagonist and agonist muscles often occur in pairs, called antagonistic pairs.

Agonist muscles and antagonist muscles refer to muscles that cause or inhibit a movement. Agonist muscles cause a movement to occur through their own contraction. For example, the triceps brachii contracts during the up phase of a push-up (elbow extension).During the down phase of a push-up, the same triceps brachii actively controls elbow flexion while relaxing.ntagonist muscles oppose a specific movement. This controls a motion, slows it down, and returns a limb to its initial position. Antagonism is not an intrinsic property; it is a role that a muscle plays depending on the motion. If a motion is reversed, agonist and antagonist muscles switch roles.
