Final answer:
In a discrete movement, the typical patterns of agonist-antagonist movement involve the interaction between the agonist and antagonist muscles. The agonist is the main muscle responsible for creating the movement, while the antagonist muscle opposes or resists the movement created by the agonist.
Step-by-step explanation:
In a discrete movement, the typical patterns of agonist-antagonist movement involve the interaction between the agonist and antagonist muscles. The agonist is the main muscle responsible for creating the movement, while the antagonist muscle opposes or resists the movement created by the agonist. For example, when flexing the knee joint, the quadriceps femoris muscles are the agonists responsible for knee extension, while the hamstrings are the antagonists responsible for knee flexion.
