Which injury is specifically caused by overstretching a muscle?

The injury specifically caused by overstretching a muscle is a strain. A strain occurs when the muscle fibers are pulled or torn due to excessive force or stretching. This can happen during activities that involve sudden movements, lifting heavy objects, or any situation where the muscle is extended beyond its normal range of motion.

In contrast, myopathy refers to muscle disease that results in muscle weakness or dysfunction, but it is not solely the result of overstretching. Dislocation involves the displacement of a joint, which is a different type of injury typically associated with trauma, rather than the overstretching of muscle tissue. Atrophy refers to the wasting away or reduction in muscle mass due to inactivity or disease, which does not relate to overstretching either. Understanding these distinctions is key to recognizing the specific causes and types of muscular injuries.
