Question: 1 / 400

What does "reciprocal inhibition" achieve during movement?

It decreases muscle tissue temperature

It allows for the relaxation of the opposite muscle while one contracts

Reciprocal inhibition is a physiological process that occurs during movement where the contraction of one muscle automatically causes the relaxation of its opposing muscle. This mechanism is crucial for smooth and coordinated movements, as it allows for better control and efficiency when performing physical activities. For example, when a person bends their arm at the elbow, the biceps brachii contracts to flex the arm, while the triceps brachii, which is the opposing muscle, will relax to enable that movement. This interplay between contraction and relaxation is essential for a fluid range of motion and helps prevent injury by ensuring that antagonistic muscles do not work against each other at the same time. Understanding this process is vital in fields such as physical therapy and sports science, where optimizing movement patterns is key to improving performance and recovery.
