What term refers to the overstretching or excessive work of muscles?

The term that refers to the overstretching or excessive work of muscles is strain. A strain occurs when a muscle or tendon is stretched beyond its normal capacity, leading to damage and pain. It commonly arises from overexertion or repetitive motions, resulting in micro-tears in the muscle fibers. This injury is often associated with symptoms such as swelling, muscle spasms, and limited range of motion.

In contrast, a sprain specifically refers to the overstretching or tearing of ligaments, which connect bones to one another, rather than muscles. Dislocation involves the displacement of bones at a joint, which can occur due to trauma but does not pertain to muscle overexertion. A fracture is a break in a bone and is a different type of injury from those involving muscle or tendon strain. Understanding the distinctions between these terms is crucial for diagnosing and treating musculoskeletal injuries effectively.
