What type of injury is caused by excessive stretching, overuse, or misuse of a muscle?

The correct answer is a strain, which refers specifically to an injury that occurs when a muscle is excessively stretched or overused. This type of injury often results from activities that involve heavy lifting, repetitive motion, or sudden movement that the muscle is not adequately prepared for. Strains can affect any muscle in the body but are particularly common in the back, hamstrings, and shoulders.

In a strain, the muscle fibers may suffer small tears, leading to pain, swelling, and limited mobility, which distinguishes it from other types of injuries. Understanding strains is crucial for both prevention and treatment, as managing activity levels and practicing proper technique can help mitigate the risk of these injuries.
