Medical Definition: The hamstring consists of three muscle groups, including the semimembranosus, semitendinousus, and the biceps femoris. A hamstring strain occurs when excessive or repetitive stress causes tearing of the muscle fibers in the hamstring. Causes: Tight hamstring muscles, muscle imbalance, sudden movement, and repetitive strain are all common types of hamstring injuries. Symptoms: A sharp pain may be felt in the hamstring when a serious strain or tear occurs. This often happens during such action as an explosive move in basketball or a quick sprint. If you feel a deep ache in the hamstring area it may be a less severe strain or minor tear. Recommended Treatment: See a medical professional for an evaluation. Rest leg as much as possible and ice after any activity to promote healing. Use a brace when participating in any strenuous activity to reduce stress to area. Stretch the hamstring muscles as long as stretching causes no pain.
