When prolonged inactivity results in the muscles getting smaller, what is this process called?

Explanation:
When muscles are not used for a long time, their fibers shrink because the rate of protein breakdown exceeds protein synthesis, leading to a loss of muscle mass and strength. This specific situation is called disuse atrophy. It’s a particular form of atrophy driven by inactivity, unlike hypertrophy, which is growth from training, and hyperplasia, which would mean more cells rather than smaller cells. General atrophy can result from aging or disease, but the term disuse atrophy pinpoints inactivity as the cause of the muscle shrinking.
