What do fixator muscles do during movement?

Fixator muscles play a crucial role during movement by providing support and stabilization to the body. They engage to maintain posture and ensure that the prime movers, which are responsible for the primary movement, can function effectively without unnecessary distraction or injury. By stabilizing the joints and the body segment involved in the movement, fixators allow for smooth, coordinated actions, making them essential for maintaining proper form and preventing injuries during physical activity.

In contrast, the primary movement is initiated by the prime movers, and opposing movements are managed by antagonist muscles. While options mentioning conduction of energy may highlight other physiological processes, they do not accurately describe the role of fixator muscles. Understanding the function of fixators highlights their importance in enhancing performance and stability during various exercises.
