1. Agonist: The agonist in a movement is the muscle(s) that provides the major force to complete the movement. Because of this agonists are known as the âprime moversâ. In the bicep curl which produces flexion at the elbow, the biceps muscle is the agonist, as seen in the image below.
Agonist works with the muscles, and the antagonist is the muscle working against it in a contraction. i.e. Bicep curl, the agonist is the Biceps brachii and the antagonist mus â¦ cle is the triceps brachii.The word agonist means producing an action - an antagonist opposes that action.uring movement, the muscle that is contracted is the agonist muscle and the opposing muscle is the antagonist, that returns the agonist muscle back to its relaxed state. 7 people found this useful.
