Law enforcement agents protect life and property, and uphold the law within a jurisdiction. Many of the job requirements are not based on education, but on one's physical and mental characteristics. To become a law enforcement agent, individuals need to complete agency training programs, such as police academy.
A muscle strain, also called a pulled muscle, occurs when a muscle is stretched too far, and microscopic tears occur within the muscle fibers. Common muscle strains include pulled hamstrings, groin strains, and calf strains. The usual symptoms of this type of injury include pain, spasm of the muscle, swelling, bruising, and limited mobility.
Pain and Tenderness. Pain is the hallmark symptom of a pulled arm muscle. Sudden pain typically occurs at the time of the injury, when the muscle or tendon fibers tear while the muscle is actively engaged. For example, a biceps strain commonly occurs when lifting a heavy object, either during weight training or while performing everyday tasks.
