What term describes the loss of muscle mass due to stopping strength training?

Explanation:
When muscles aren’t used regularly, they shrink because the body reduces the size of the muscle fibers in response to decreased demand. This loss of muscle mass from stopping strength training is called atrophy. Hypertrophy would be growth in muscle size from training, not loss. Hyperplasia refers to an increase in the number of muscle fibers (not common in skeletal muscle for strength changes), and metaplasia is a tissue-type change, not a reduction in muscle size.
