The correct answer here is "antagonist."

Explanation

In biomechanics and muscle physiology, antagonists are muscles that oppose the action of other muscles, referred to as agonists. When an agonist muscle contracts to perform a movement, the antagonist muscle relaxes to allow that movement to occur smoothly. For example, when you flex your bicep (the agonist), your tricep works to relax (the antagonist) to facilitate the movement.

This coordinated effort is crucial for balanced movement and changes of direction. Each pair of agonist and antagonist muscles work in harmony to ensure that the movements are controlled and that the joints are stabilized. Furthermore, understanding the roles of agonists and antagonists is essential for designing effective training programs and rehabilitation protocols. Overall, antagonists play a significant role in not only reversing movement but also in maintaining proper posture and joint integrity.
