What does myositis refer to?

Myositis refers specifically to inflammation of muscle tissue. This condition can arise from various causes, including autoimmune diseases, infections, and injuries. Inflammation leads to symptoms such as pain, weakness, swelling, and sometimes stiffness in the affected muscles. Understanding myositis is important for athletic training and rehabilitation since it can significantly impact a person’s ability to perform physical activities and require targeted treatment strategies to manage inflammation and promote healing.

The other options describe different conditions or symptoms related to muscles but do not accurately define myositis. For example, stiffness in muscles refers broadly to discomfort in muscle flexibility, while a muscle strain is primarily due to overexertion and involves the tearing of muscle fibers rather than inflammation. Persistent muscle fatigue without inflammation would indicate an entirely different issue that does not pertain to the inflammatory processes characteristic of myositis.
