What does a strain refer to in terms of injury?

A strain refers specifically to an injury that affects muscles or tendons. Muscles are responsible for movement, and tendons connect those muscles to bones. When a muscle or tendon is overstretched or torn, it is classified as a strain. This type of injury commonly occurs during physical activity when muscles are exerted beyond their normal capability, leading to pain, swelling, and a reduced range of motion in the affected area. Understanding the distinction of strains is crucial for effective injury prevention and management, especially in physically demanding roles such as law enforcement, where the risk of such injuries can be higher due to the physical nature of the job.
