The hamstring refers to a group of three muscles located at the back of the thigh. These muscles are called the biceps femoris, semitendinosus, and semimembranosus. They play a crucial role in bending the knee and extending the hip, which is important for activities like running, jumping, and walking.
Injuries to the hamstring are common, especially among athletes. A hamstring strain can occur when these muscles are stretched too far or torn, leading to pain and difficulty moving. Proper warm-up exercises and stretching can help prevent such injuries, allowing individuals to stay active and enjoy their favorite sports.
