In the contact and recovery phase, the quadriceps contract to extend the knee while the hamstrings lengthen to allow the movement. The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist. An agonist is something that causes a specific physiological response in the cell. Knee action: Extension. There is a specific pattern to the sequence of muscle activation involved during joint movement. Twitter. Pecs (horizontal adduction, flexion, extension, medial rotation): Agonist - Triceps brachii. An agonist muscle is the source of the force needed to finish a movement and to achieve this it must contract (shorten) or relax (lengthen). As the muscles contract across the shoulder joint it brings your shoulder upward into flexion as you push the ball the opposite happens and the antagonist becomes your deltoid and the latissimus dorsi becomes your agonist. An example of an antagonist muscle would be the triceps during a biceps curl Fixator • The fixator in a movement is the muscle/s .
