True or False: The statement 'True synergy occurs when a muscle contracts to stop the secondary action of another muscle' is accurate?

1. True

2. False

3. Only in specific exercises

4. Not relevant to muscle training

The correct answer is: True

The statement is accurate because it reflects the concept of true synergy in the context of muscle function. True synergy refers to the coordinated action of different muscles to achieve a movement more efficiently and effectively. When one muscle contracts to modulate or stop the secondary action of another muscle, it allows for smooth and controlled movement, preventing unwanted force or motion that could lead to injury or inefficiency. This is particularly important in complex movements where multiple muscles are engaged. For instance, while performing a movement like a squat, the primary muscles (like the quadriceps and hamstrings) work together, but synergistic muscles (such as the glutes) also engage to stabilize the motion and control the movement pattern. In summary, true synergy enhances movement coordination and stability by ensuring that while one muscle is active, another muscle effectively manages the overall action, contributing to optimal performance and reduced risk of injury.
