Final answer:
GTOs inhibit contracting muscles and excite antagonist muscles to prevent injury.
Step-by-step explanation:
GTOs inhibit contracting (agonist) muscles and excite antagonist muscles to prevent injury. When a muscle contracts, the agonist muscle is responsible for the movement, while the antagonist muscle works in opposition to it, allowing for controlled movement and preventing injury. The inhibitory role of GTOs help regulate the tension and prevent muscles from exerting excessive force, which can result in damage or injury.
