What are the three muscles that comprise the hamstring group?

The hamstring group is made up of three specific muscles located at the back of the thigh, which play a critical role in various movements, particularly those involving bending the knee and extending the hip. The correct muscles that comprise this group are the Biceps Femoris, Semitendinosus, and Semimembranosus.

These muscles work to facilitate actions like running, jumping, and squatting, making them essential for athletic performance and everyday movements. The Biceps Femoris is unique in that it has two heads and plays a role in both knee flexion and hip extension. The Semitendinosus and Semimembranosus are similarly involved in these functions but also contribute to internal rotation of the knee when it is flexed.

Understanding these muscles and their functions is fundamental in both rehabilitation and strength training, as they often need to be properly activated and strengthened to prevent injuries, particularly during activities that require explosive movements.
