Some people do not know what a hamstring is. They just know they are easy to pull when running. The hamstrings are the three posterior muscles in the thigh (on the back of the leg) located between a person’s hip and their knee. They consist of the three muscles. These include the semitendinosus, semimembranosus, and biceps femoris muscles. Together, they work to bend the leg at the knee and to extend the leg straight behind the body. They are important muscles, but they are susceptible to injury.
Information. Hamstring injuries are infamous for sometimes being very painful, but of course, everyone is different, just as every injury is different. Luckily, there are several easy ways to treat and help prevent them. But what exactly are they? And what exactly happens in the leg during this type of injury? In short, a hamstring injury occurs when one or more of the three hamstring muscles become strained, overloaded, pulled, or even torn. The injury can cause a number of symptoms ranging from mild discomfort to surgery-requiring pain and damage. As these are very common injuries, they are often caused by people over-exerting themselves during sports or not properly stretching before being physically active.
